Description

Bare metal server route updating method and device, electronic equipment and medium

Technical Field

The invention relates to the field of cloud computing, in particular to a bare metal server route updating method and device, electronic equipment and a medium.

Background

Common cloud computing is implemented in a virtual machine manner based on physical resource sharing. However, with the development of technology, more and more applications need high-performance computing platforms, and a bare metal server is one of the high-performance computing platforms, wherein when the bare metal server is used as the high-performance computing platform, the bare metal server also has the advantages of low latency, exclusive tenant and the like.

The Overlay network is a novel network which is operated on a traditional network and is completely isolated from an underlying network by adopting a transmission layer packaging technology, such as a virtual extensible local area network VxLAN, a virtual network NVGER packaged by a general routing, a virtual network GENEVE packaged by a general network and the like. The largest characteristic of the Overlay network is that any subnet address can be selected, and different tenants can use the same IP address.

The underlying Underlay underwlay network is a network carrying an Overlay network, i.e. a network based on two-layer switching and three-layer routing forwarding technology in the traditional sense.

In order to meet the requirements of users for accessing different services, a bare metal server needs to be connected with an Underlay network and an Overlay network at the same time. However, the virtual network management component Neutron only implements management of the Overlay network, and for the Underlay network, Neutron is difficult to manage. Therefore, when the bare metal server needs to access services on both the Underlay network and the Overlay network, when the tenant creates a network, it is easy for the input IP address segment to collide with the address of the Underlay network. In addition, for advanced network functions such as load balancing, source address translation SNAT, destination address translation DNAT, etc., a partial IP address field needs to be reserved, which is different from the IP address inside the bare metal server, so as to avoid conflict.

Aiming at the problems that the addresses of the two networks of underwritay and Overlay can not conflict and the routing has no interference, the existing solution is to maintain all IP address segments which can not be used by the tenant virtual network by configuring a white list through a cloud management platform. That is, when an Underlay network and an Overlay network exist in a bare metal server at the same time, in order to avoid IP address or route conflicts, it is necessary to determine in advance an IP address segment occupied by the Underlay network and the Overlay network and a reserved network address segment. Then, the network address segments are shielded on the cloud management platform, so that the user cannot use the network address segments which conflict with the planning when the user creates the tenant network. Finally, after the bare metal server is created, routing information needs to be configured inside the bare metal server manually or in a preset script mode.

Because the cloud management platform does not uniformly manage the IP address segments and the reserved network address segments occupied by the Underlay network and the Overlay network, which are determined in advance, in the bare metal server, when the network address segments are determined in advance or reserved and need to be changed, routing information of the bare metal server needs to be checked and modified one by one to ensure that new routing information can take effect in the bare metal server.

Therefore, in the prior art, when the network address changes, a great deal of energy is needed to perform routing update on the created bare metal server.

Disclosure of Invention

The invention provides a bare metal server route updating method, a bare metal server route updating device, electronic equipment and a bare metal server route updating medium, which are used for solving the problem that in the prior art, when a network address on a bare metal server changes, a great deal of energy is needed to perform route updating on the created bare metal server.

In order to solve the above technical problem, according to an aspect of the present invention, there is provided a bare metal server route updating method applied to a cloud platform, the method including:

determining a target bare metal server for performing routing update according to the obtained changed first IP address segment and a corresponding second IP address segment stored for each bare metal server, wherein the first IP address segment is an IP address segment occupied by an Overlay network and/or a bottom-layer Underlay network;

acquiring tenant information of the target bare metal server;

and generating a first routing information table according to the first IP address field and the tenant information, and sending the first routing information table to the target bare metal server.

As can be seen from the above description, in the present invention, the cloud platform uniformly stores and manages the IP address segments occupied by the Overlay network and/or the Underlay network on the bare metal server and the routing table of the bare metal server. Therefore, when the network address on the bare metal server changes, the cloud platform can determine a target bare metal server needing routing change according to the changed IP address field, then automatically generates a first routing information table according to tenant information accessed to the target bare metal server, issues the first routing information table to the target bare metal server, and updates the target bare metal server according to the first routing information table. Therefore, the established bare metal server is not required to be subjected to route updating by a great deal of labor, the workload of manually adjusting the route can be saved, and the work efficiency of route updating of the bare metal server is greatly improved

Specifically, the method further comprises:

and receiving response information sent by the target bare metal server after the target bare metal server finishes updating the routing information table stored in the target bare metal server according to the first routing information table.

By receiving the response information sent by the target bare metal server, the routing update of the target bare metal server can be confirmed, and the cloud platform can store the latest routing information of the target bare metal server conveniently.

Specifically, the determining, according to the obtained changed first IP address segment and the corresponding second IP address segment stored for each bare metal server, a target bare metal server for performing routing update includes:

acquiring an IP address field change notification sent by a cloud management platform aiming at an IP address field occupied by an Overlay network and/or an Underlay network, wherein the IP address field change notification carries information of the first IP address field;

and determining a target second IP address segment corresponding to the first IP address segment according to the first IP address segment and a corresponding second IP address segment stored for each bare metal server, and taking the bare metal server corresponding to the target second IP address segment as a target bare metal server.

Here, after receiving the IP address segment change notification sent by the operation and management platform, the cloud platform can actively confirm the target bare metal server that needs to be subjected to routing update according to the IP address segment change notification, thereby realizing automatic update of routing information of the bare metal server without performing a troubleshooting on a per-station basis.

Specifically, the determining, according to the first IP address segment and the corresponding second IP address segment stored in each bare metal server, a target second IP address segment corresponding to the first IP address segment includes:

judging whether an address field corresponding to the first IP address field is a universal IP address field or not according to the universal IP address field aiming at all bare metal servers in the second IP address field;

if yes, the general IP address field is used as a target second IP address field;

if not, judging a specific IP address segment corresponding to the first IP address segment, and taking the specific IP address segment corresponding to the first IP address segment as a target second IP address segment.

Specifically, the taking the bare metal server corresponding to the target second IP address segment as the target bare metal server includes:

when the general IP address field is used as a target second IP address field, determining that the target bare metal server is all bare metal servers;

and when the specific IP address segment corresponding to the first IP address segment is taken as a target second IP address segment, determining that the target bare metal server is the bare metal server of the corresponding specific IP address segment.

Because the IP address field occupied by the Overlay network and/or the Underlay network comprises the general IP address field and the specific IP address field, the target bare metal server can be judged more conveniently by judging whether the first IP address field corresponds to the general IP address field or the specific IP address field.

Specifically, the determining, according to the obtained changed first IP address segment and the corresponding second IP address segment stored in each bare metal server, a target bare metal server for performing routing update further includes:

receiving a routing update request sent by a first bare metal server;

judging whether an IP address field change notification sent by a cloud management platform aiming at an IP address field occupied by an Overlay network and/or an Underlay network is acquired, wherein the IP address field change notification carries information of the first IP address field;

if so, judging whether a corresponding second IP address field stored aiming at the first bare metal server corresponds to the first IP address field;

and if so, determining the first bare metal server as a target bare metal server.

Specifically, the receiving a route update request sent by a first bare metal server includes:

receiving a route updating request sent by the first bare metal server according to a preset period; alternatively, the first and second electrodes may be,

receiving a routing update request sent by the first bare metal server according to a control message protocol ICMP notification, wherein when the cloud platform detects that the first bare metal server sends service traffic to an error gateway, the cloud platform sends the ICMP notification to the first bare metal server.

Here, the cloud platform receives a route update request sent by the bare metal server, and in order to determine whether the bare metal server needs to perform route update, it needs to actively determine whether an IP address segment change notification sent by the cloud management platform is received, and if so, determines the target bare metal server. Therefore, the mode of triggering the routing update of the bare metal server is more intelligent and can be suitable for different cloud environments.

According to another aspect of the present invention, there is also provided a bare metal server route updating method, applied to a bare metal server, the method including:

receiving a first routing information table sent by a cloud platform;

and updating the locally stored routing information table according to the first routing information table.

Because the bare metal server is provided with the routing configuration agent, the bare metal server can automatically update the routing after receiving the first routing information sent by the cloud platform, manual configuration is not needed, and the workload of manually adjusting the routing is saved, so that the automation level is improved, and the cost of synchronizing the routing information is reduced.

Specifically, the method further comprises:

and according to the first routing information table, after the locally stored routing information table is updated, response information of the updated routing information table is sent to the cloud platform.

By sending the response information to the cloud platform, it can be confirmed that the routing information table locally stored by the bare metal server is consistent with the routing information table stored on the bare metal server on the cloud platform, that is, the bare metal server is updated.

Specifically, before receiving the first routing information table sent by the cloud platform, the method further includes:

Specifically, the sending the route update request to the cloud platform includes:

a route updating request is sent according to a preset period; alternatively, the first and second electrodes may be,

receiving a control message protocol ICMP notification sent by the cloud platform, wherein the ICMP notification is sent when the cloud platform detects that the metal server sends service traffic to an error gateway;

and sending a route updating request according to the ICMP notification.

The bare metal server can send a route updating request to the cloud platform, and the route table information stored locally is actively changed, so that automatic updating on the bare metal server is realized, the route updating mode of the bare metal server is triggered more intelligently, and the method is applicable to different cloud environments.

Specifically, the updating the routing information table stored in the first routing information table according to the first routing information table includes at least one of the following:

deleting the corresponding routing entry from the locally stored routing information table according to the first routing information table; and

and modifying the corresponding routing entry for the locally stored routing information table according to the first routing information table.

Because the changed IP address field can be the deletion, the expansion or the modification of the original IP address field, the routing information table also needs to be changed correspondingly so as to ensure that the accessed tenant network can successfully access the corresponding network and avoid the bare metal server sending the service flow to the wrong gateway.

Detailed Description

The invention provides a bare metal server route updating method, a bare metal server route updating device, electronic equipment and a medium, and aims to solve the problem that in the prior art, when a network address on a bare metal server changes, a large amount of labor is required to perform route updating on the created bare metal server.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The first embodiment is as follows:

in the prior art, although the cloud management platform may maintain the Underlay network and the Overlay network on the bare metal server, the cloud management platform does not store and manage the IP address fields occupied by the Underlay network and the Overlay network on the bare metal server in a unified manner. Therefore, in order to realize the uniform storage and management of the IP address fields occupied by the Underlay network and the Overlay network on the bare metal server, the cloud platform is added between the cloud management platform and the bare metal server, and the cloud platform uniformly stores and manages the IP address fields occupied by the Overlay network and/or the Underlay network on the bare metal server and the routing information table of the bare metal server.

Therefore, according to an aspect of the embodiments of the present invention, a bare metal server route changing method is provided, the bare metal server route updating method provided by the embodiments of the present invention is applied to a cloud platform, and is specifically applied to an electronic device installed with the cloud platform, fig. 1 is a flowchart of the bare metal server route changing method in the embodiments of the present invention, and as shown in fig. 1, the method includes the following steps:

step S101, determining a target bare metal server for performing routing update according to the obtained changed first IP address segment and a corresponding second IP address segment stored for each bare metal server, wherein the first IP address segment is an IP address segment occupied by a covering layer Overlay network and/or a bottom layer Underlay network.

In the embodiment of the present invention, as can be seen from fig. 2, the cloud platform is connected to the cloud management platform and the bare metal server, so that the cloud platform can obtain and store the network address plan about the IP address segment occupied by the Overlay network and/or the Underlay network on the bare metal server and issued by the cloud management platform, and can also issue the initialized routing information or the changed routing information to the corresponding bare metal server. Therefore, the IP address fields occupied by the Overlay network and/or the Underlay network are effectively stored and managed through the cloud platform, the problem of IP address or route conflict in the bare metal server is solved, and the complexity of maintaining the Overlay network and/or the Underlay network is reduced.

It should be noted that a plurality of bare metal servers can be accessed on one cloud platform. And for each bare metal server, the IP address field occupied by the corresponding Overlay network and/or the Underlay network is different. Therefore, the cloud platform can determine the bare metal server needing to be subjected to the route change by comparing the changed first IP address segment with the IP address segment occupied by the saved Overlay network and/or the Underlay network, and the cloud platform does not need to manually perform investigation one by one, so that the workload of manually updating the route is saved.

And S102, acquiring tenant information of the target bare metal server.

Generally, when a server accesses a network, two routing methods are adopted: default route and detailed route. By default route, it is meant a route selected when there is no matching route entry between destination addresses in the routing table, with both the destination IP and subnet segments changed to 0.0.0.0 and 0.0.0.0. The detail routing means routing information manually configured by a user or a network administrator, and a destination IP and a subnet segment thereof need to be set. For example, for a certain tenant network, the subnet segment of the corresponding Overlay network is 192.168.1.0/24, and the gateway is 192.168.1.254, the cloud platform automatically issues the route shown in table 1, where the first behavior in table 1 is detailed route and the 2 nd behavior is default route.

TABLE 1

Destination	Netmask	Nexthop
			192.168.1.0	255.255.255.0	192.168.1.254
0.0.0.0	0.0.0.0	192.168.1.254

Therefore, after the cloud platform determines the target bare metal server to be changed, the cloud platform should acquire tenant information of the tenant network accessed to the target bare metal server to generate the first routing information table corresponding to the changed first IP address segment.

Step S103, generating a first routing information table according to the first IP address segment and the tenant information, and sending the first routing information table to the target bare metal server.

The cloud platform automatically generates a first routing information table according to the changed first IP address segment and tenant information of a tenant network accessed to the target bare metal server in a mode of detailed routing in the table 1 and issues the first routing information table to the target bare metal server, wherein the bare metal server is configured with a routing configuration agent, so that after the target bare metal server receives the first routing table issued by the cloud platform, the routing configuration agent automatically updates according to the first routing table, and a worker does not need to perform routing configuration in a manual or script preset mode, so that the process of updating the bare metal server routing is automated, and the workload of manually updating the routing is saved. In addition, compared with a mode that a worker manually or presets a script, the method can avoid errors caused by manual operation in the route configuration process, and greatly improves the efficiency and the accuracy of the route configuration.

Therefore, in the embodiment of the invention, compared with the prior art, a great deal of energy is not needed to be consumed to update the route of the established bare metal server, the workload of manually adjusting the route can be saved, the working efficiency of updating the route of the bare metal server is greatly improved, and the cost of updating the route of the bare metal server is reduced.

It should be noted that, on the cloud platform, the information format of the IP address field occupied by the Overlay network and/or the Underlay network on each bare metal server is shown in table 2. It is understood that, in the embodiment of the present invention, the information format of the IP address segment occupied by the cloud platform for the Overlay network and/or the Underlay network on each bare metal server is not limited to the reference format in table 2.

TABLE 2

Address segment	Gateway	Use of	Type (B)
				10.10.0.0/16	*	Management network	Underlay
10.20.0.0/16	*	Storage network	Underlay
				172.10.0.0/16	*	External network	Overlay

As can be seen from the reference format given in table 2, the information format of the IP address field occupied by the cloud platform for the Overlay network and/or the Underlay network on each bare metal server mainly includes an address field and gateway information. Since the address field may be an aggregated address and correspond to a plurality of pre-planned gateways, specific gateway information is not given in table 2.

For the application scenario given in table 2 as an example, the IP address segment occupied by the Overlay network and/or the Underlay network stored in the cloud platform mainly includes the following three aspects:

1) the portion of the underwlay network plans or reserves address segments for physical network addresses. Such as a storage network, a management network, etc. in the table.

2) And an Overlay external network, which is used for planning a network for providing services for the bare metal server for the administrator. Such as a CMNET public network or an IP bearer network, and the like, have a corresponding relationship with an actual underlying physical network.

3) The Overlay service network, which is a virtual network (or called tenant network) customized by a user, uses an address field which must be removed from the occupied or planned address field.

In addition, since the address field may be an aggregated address, the address field may correspond to a plurality of pre-planned gateways, and therefore, in the IP address field occupied by the Overlay network and/or the Underlay network, a part of the IP address field is a general IP address field that can be commonly used by all bare metal servers, and another part of the IP address field is a specific IP address field that is specific to a part of bare metal servers and different from other bare metal servers. Wherein the specific IP address field is related to the network location of the part of bare metal server and the application carried on it.

Since in general, the bare metal server is routed to the Overlay network by default and to the Underlay network by explicit routing. Therefore, in the embodiment of the present invention, mainly for the above situation, an initialization process of route configuration on a bare metal server is described, where the initialization process is as shown in fig. 3.

As can be seen from the above, the IP address segments occupied by the Overlay network and/or the Underlay network can be divided into the general IP address segment and the specific IP address segment, so that when performing initialization configuration, the detailed route can be generated according to the general IP address segment in the Underlay network and in the manner in table 1, and then the part of the detailed route can be saved as the general route table, and then the detailed route can be generated according to the specific IP address segment in the Underlay network and in the manner in table 1, and then the part of the detailed route can be saved as the specific route table applicable to the part of the bare metal server. Wherein the generic routing table is shown in table 3 and the specific routing table is shown in table 4.

			10.10.0.0	255.255.0.0	10.10.1.254

				BM1	10.10.10.0	255.255.255.0	10.10.10.254
BM2	10.20.10.0	255.255.255.0	10.20.10.254

As can be seen from table 3, the generic routing table does not specifically limit the model of the bare metal server. As can be seen from table 4, the model number of the bare metal server corresponding to each routing entry needs to be marked in the specific routing table to distinguish between different bare metal servers, such as the first row routing entry in table 4 corresponding to BM1 in table 4, and the second row routing entry in table 4 corresponding to BM 2.

It should be understood that, in the embodiment of the present invention, the initialization process of the route configuration on the bare metal server is also applicable to a scenario where the default route goes through an Underlay network, or a scenario where the explicit route goes to an Overlay network, and in the embodiment of the present invention, the comparison is not specifically limited.

For example, tenant a creates a tenant network, the corresponding subnet segments are 192.168.1.0/24, and the gateways are 192.168.1.1, and the network plan of the IP address segments occupied by the Overlay network and/or the Underlay network is shown in table 5.

TABLE 5

Address segment	Gateway	Use of	Type (B)
				10.10.0.0/16	*	Management network	Underlay
172.10.0.0/16	*	External network	Overlay

The generated default route is as follows:

the address field is 0.0.0.0/0, and the gateway is 192.168.1.1.

The detailed routing on the Underlay network is as follows:

the address field is 10.10.0.0/16, and the gateway is an Underlay network access gateway corresponding to the bare metal server.

The detailed routing on the Overlay network is as follows:

the address field is 172.10.0.0/16, and the gateway is 192.168.1.1.

As can be seen from the above, for the same tenant, the Underlay network and the Overlay network respectively generate detailed routes, where in the detailed routes on the Overlay network, the gateway is the gateway of the tenant, and in the detailed routes on the Underlay network, the gateway is the Underlay network access gateway corresponding to the bare metal server. The routing configuration on the Underlay network is more complicated when the routing configuration is performed, so that errors are more likely to occur when the routing configuration is performed manually. Therefore, in the embodiment of the invention, the cloud platform automatically generates the routing information table according to the stored tenant information and the IP address fields occupied by the Underlay network and the Overlay network, so that the method is more reliable, errors caused by manual operation in the routing configuration process can be avoided, and the efficiency and the accuracy of routing configuration are greatly improved.

In the detailed routing on the Underlay network, the address of the Underlay network access gateway corresponding to the bare metal server is determined according to the network location where the bare metal server is located, for example, the address of the gateway of the bare metal server hung under the Underlay network access switch a is 10.10.1.1, and the address of the gateway of the bare metal server hung under the Underlay network access switch B is 10.10.2.1.

Similarly, in a specific route, the Underlay network access gateway corresponding to the bare metal server is also mainly determined by the location of the bare metal server, the type of the server, the requirements of the service party, the network policy, and the like.

For example, a Hadoop server installed in a harbourine room needs to access a Master node (IP: 100.1.1.1) deployed in an Underlay network, and may correspond to a specific route: the address segment is 100.1.1.1/32, and the gateway is the Underlay network access gateway corresponding to the bare metal server. The gateway is determined by the position of the Master node, the type of the server, the requirement of a service party and the network policy.

Specifically, in the embodiment of the present invention, to determine that the target bare metal server has performed the route update, the method further includes: and receiving response information sent by the target bare metal server after the target bare metal server finishes updating the routing information table stored in the target bare metal server according to the first routing information table.

Therefore, by receiving the response information sent by the target bare metal server, it can be determined that the routing information table on the target bare metal server is synchronized with the routing information table of the target bare metal server stored on the cloud platform, and the cloud platform is prevented from resending the first routing information table to the target bare metal server, so that the computation load of the cloud platform is increased.

Specifically, in the embodiment of the present invention, when determining the target bare metal server for performing the route update, the cloud platform may determine the target bare metal server for performing the route update according to the changed IP address segment after receiving the IP address segment change notification sent by the cloud management platform, or the cloud platform may determine whether the IP address segment change notification sent by the cloud management platform is received after receiving the route update request sent by the bare metal server, and if so, determine the target bare metal server for performing the route update according to the changed IP address segment. Namely, the cloud platform can actively judge whether the change notification of the IP address field sent by the cloud management platform is received according to the route update request sent by the bare metal server, and can also passively and directly receive the change notification of the IP address field sent by the cloud management platform.

The following describes two cases of determining a target bare metal server for performing routing update with reference to specific embodiments.

Example two:

in the embodiment of the present invention, determining, according to the obtained changed first IP address segment and the corresponding second IP address segment stored in each bare metal server, a target bare metal server for performing routing update includes:

The embodiment of the invention mainly describes that the cloud platform passively and directly receives an IP address field change notification sent by the cloud management platform, and determines a target second IP address field corresponding to a first IP address field from IP address fields occupied by an Overlay network and/or an Underlay network on a plurality of bare metal servers according to information of the first IP address field carried in the IP address field change notification, thereby determining a target bare metal server needing to perform route updating from the plurality of bare metal servers.

This kind of mode is after the cloud platform receives the IP address section update notice that the cloud manages the platform and send, can trigger to the automatic route update that carries out of the naked metal server of target who determines, consequently whenever carries out the network address change, can all realize carrying out the route update to the naked metal server of target is automatic, has promoted route update efficiency to a great extent, need not to go on through the manual work again and investigate one by one, has saved the work load of artifical update route.

As can be seen from the foregoing embodiments, the IP address segments occupied by the Overlay network and/or the Underlay network include a general IP address segment and a specific IP address segment.

Therefore, determining a target second IP address segment corresponding to the first IP address segment according to the first IP address segment and the corresponding second IP address segment stored for each bare metal server comprises:

judging whether an address field corresponding to the first IP address field is a universal IP address field or not according to the universal IP address field aiming at all bare metal servers in the second IP address field; if yes, the general IP address field is used as a target second IP address field;

When the target second IP address field is a general IP address field corresponding to all bare metal servers, judging that the target bare metal servers are all bare metal servers; and when the target second IP address field is a specific IP address field corresponding to a part of bare metal servers, judging that the target bare metal servers are part of bare metal servers of the corresponding specific IP address field.

Therefore, in the embodiment of the present invention, the IP address segments occupied by the Overlay network and/or the Underlay network are uniformly stored and maintained through the cloud platform, so that when a target bare metal server requiring routing update is determined, whether the first IP address segment that is changed corresponds to the general IP address segment or the specific IP address segment can be preferentially determined, and the target bare metal server can be determined conveniently and quickly. Compared with the method in the prior art, which requires the personnel to check one by one, the method greatly improves the efficiency of route updating and saves the workload of manually adjusting the route.

In the above embodiment, the process of updating the routing of the initialization configuration of the bare metal server is briefly described by taking a scenario in which the bare metal server is routed to the Overlay network by default and is routed to the Underlay network by detail as an example.

As shown in fig. 4, an administrator uses a transportation and management platform as an entrance to update an IP address segment occupied by an Underlay network, a cloud platform receives a changed first IP address segment sent by the transportation and management platform, then the cloud platform determines a target bare metal server needing a routing change according to the changed first IP address segment and the IP address segment occupied by the Underlay network, and then the cloud platform generates a first routing information table according to the changed first IP address segment and tenant information accessed to the target bare metal server, and notifies the target bare metal server of a routing update.

Example three:

receiving a routing update request sent by a first bare metal server;

As can be seen from the foregoing embodiment, a plurality of bare metal servers may be connected to the cloud platform, and each bare metal server may send a routing update request to the cloud platform in order to ensure that the information of the routing table corresponding to the bare metal server stored on the cloud platform is consistent with the information of the routing table corresponding to the bare metal server stored on the cloud platform, so that the cloud platform may actively determine whether an IP address segment change notification sent by the cloud management platform is received after receiving the routing update request sent by the bare metal server, and if so, determine a target bare metal server that needs to perform routing update, and send a first routing information table generated according to the IP address segment that has changed and tenant information to the target bare metal server. The cloud platform generates a first routing information table according to the routing update request sent by the bare metal server, and notifies the bare metal server of a routing update process as shown in fig. 5.

In the embodiment of the invention, the cloud platform actively updates the route according to the route updating request sent by the bare metal server. Therefore, the mode of triggering the cloud platform to update the routing of the bare metal server can timely update the routing information on the bare metal server with the changed network address, and the intelligent automatic updating of the routing information on the bare metal server is realized.

In addition, it should be noted that, in the embodiment of the present invention, the route update request may be sent by the bare metal server according to a preset period, which can ensure that the cloud platform finds the target bare metal server that needs to perform the route update in time, and performs the route update in time, and is applicable to different cloud environments.

In the embodiment of the present invention, the route update request may also be passively sent to the cloud platform by the bare metal server according to the ICMP notification. The ICMP notification is sent to the bare metal server when the cloud platform detects that the bare metal server sends the service traffic to the wrong gateway. Because the reason why the bare metal server sends the service traffic to the error gateway may be that a locally stored routing information table in the bare metal server is different from a routing information table stored in the cloud platform, in order to determine whether the bare metal server sends the service traffic to the error gateway due to the reason, the bare metal server sends a routing update request to the cloud platform to store that the locally stored routing information table in the bare metal server is synchronized with the routing information table stored in the cloud platform. Although the method for triggering the cloud platform to update the route of the bare metal server is not periodic, the synchronization between the locally stored route information table in the bare metal server and the route information table stored in the cloud platform is ensured to a certain extent.

To sum up, in the bare metal server routing update method provided in the above embodiment, the cloud platform is added between the cloud management platform and the bare metal server, and the cloud platform uniformly stores and manages the IP address segment occupied by the Overlay network and/or the Underlay network on the bare metal server and the routing table of the bare metal server, so that when the routing update is performed, the workload of manually adjusting the routing can be saved, the work efficiency of performing the routing update on the bare metal server is greatly improved, and the cost of performing the routing update on the bare metal server is reduced.

Example four:

on the basis of the foregoing embodiment, according to another aspect of the embodiment of the present invention, an embodiment of the present invention further provides a route update method for a bare metal server, where the route update method for the bare metal server provided by the embodiment of the present invention is applied to the bare metal server, and is specifically applied to an electronic device installed with the bare metal server, as shown in fig. 6, the method includes the following steps:

step S601: receiving a first routing information table sent by a cloud platform;

step S602: and updating the locally stored routing information table according to the first routing information table.

The bare metal server runs a routing configuration agent, which is used for acquiring a routing table of the bare metal server where the bare metal server is located and performing routing configuration on the bare metal server where the bare metal server is located according to the routing table. Therefore, when the target bare metal server is determined to need to perform route updating, the route configuration agent in the target bare metal server needs to automatically acquire the first route information table and perform updating according to the route information in the first route information table.

Therefore, in the embodiment of the invention, the routing configuration agent is introduced into the bare metal server, so that the routing table stored on the bare metal server is automatically updated according to the first routing information table, and the workload of manually adjusting the routing is saved, thereby improving the automation level and reducing the cost of synchronizing routing information.

Wherein, in the embodiment of the present invention, the method further includes:

By sending the response information to the cloud platform, it can be determined that the routing information table on the target bare metal server is synchronized with the routing information table of the target bare metal server stored on the cloud platform, so that the cloud platform is prevented from sending the first routing information table again, and the operation amount of the cloud platform is increased.

In this embodiment of the present invention, the updating, according to the first routing information table, the routing information table stored in the first routing information table includes at least one of:

1) adding corresponding routing entries to a locally stored routing information table according to the first routing information table;

2) deleting the corresponding routing entry from the locally stored routing information table according to the first routing information table;

3) and modifying the corresponding routing entry for the locally stored routing information table according to the first routing information table.

As can be seen from the above embodiments, the generated routing information table is related to the changed first IP address field, regardless of the default route or the detailed route, where the change of the first IP address field includes the following three cases:

1) deleting an IP address field occupied by an Overlay network and/or an Underlay network;

2) expanding an IP address field occupied by an Overlay network and/or an Underlay network;

3) the segments of the IP address occupied by the Overlay network and/or the Underlay network are modified.

Therefore, for the change of the three IP address fields, the updating of the stored routing information table correspondingly includes: adding corresponding routing entries to the existing routing entries in the routing information table stored therein, or deleting corresponding routing entries to the existing routing entries in the routing information table stored therein, or modifying corresponding routing entries to the existing routing entries in the routing information table stored therein.

When the routing information is updated, the routing information table locally stored on the whole bare metal server does not need to be replaced, and only the changed routing table needs to be updated, so that a large storage space is not occupied, and the updating speed and efficiency are improved.

In this embodiment of the present invention, before receiving the first routing information table sent by the cloud platform, the method further includes:

and sending a route updating request to the cloud platform.

Wherein sending a route update request to the cloud platform comprises:

and sending a route updating request according to the ICMP notification.
