Detailed Description
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.
At present, communication schemes of bare metal and cloud platform networks have three modes of pure software implementation, hardware switch implementation and intelligent network card implementation. The pure software implementation mode has low hardware requirement, but the available functions are few, and most functions of the virtual machine are difficult to implement. The overlay network can be encapsulated based on a hardware switch mode and an intelligent network card mode, so that bare metal has the same function as a virtual machine and achieves the function which cannot be realized by pure software, but the two modes both need to purchase a specific hardware switch or an intelligent network card and have higher use cost.
According to the method and the device, the soft gateway node has the function of providing the deployment service for the bare metal node by establishing the connection relation of the internal information of the soft gateway node, and the soft gateway node has the same characteristics as the virtual machine, so that the bare metal node can realize the same network functions as the virtual machine through the soft gateway node, including communication with an overlay network, setting of a security group, qos, distributed floating IP and the like.
The embodiment of the invention discloses a control method of a bare metal node, which is applied to a soft gateway node, wherein the soft gateway node comprises a physical network card and an overlay network card, the physical network card is connected with the bare metal node, the overlay network card is connected with any node in an overlay network, and the control method comprises the following steps:
s1: creating a soft network bridge corresponding to the physical network card and creating a common network bridge corresponding to the overlay network card;
s2: connecting the common network bridge with the soft network bridge, and connecting the common network bridge with the deployment service in the soft gateway node;
specifically, the process of connecting the ordinary network bridge and the soft network bridge includes:
respectively setting a patch interface on the common network bridge and the soft network bridge, and linking the two patch interfaces into a patch interface pair;
and each bare metal node corresponds to one patch interface pair.
As shown in fig. 2, the physical network card is connected to the bare metal node through the switch, the soft bridge and the overlay network card corresponding to the physical network card are connected through a patch interface pair, the interface pair includes a patch interface v-bm and a repr-bm, and the normal network bridge is also connected to the deployment service, so as to ensure a subsequent traffic path.
S3: acquiring initial information of the bare metal node through a physical network card, and sending the initial information to a deployment service through a soft network bridge and a common network bridge in sequence;
s4: and deploying the bare metal node according to the initial information through the deployment service so as to enable the deployed bare metal node to communicate with the overlay network.
Specifically, the process of deploying the bare metal node by the deployment service according to the initial information includes:
the deployment service performs the following operations:
acquiring dhcp information according to the initial information to determine the communication deployment information of the bare metal node;
and deploying the bare metal nodes according to the communication deployment information.
Further, the deployment service is specifically an ironic service.
It can be understood that before the bare metal node is not deployed by the deployment service, a representative port of the soft gateway node for the bare metal node is an open representative port, which is applied to a current patch interface pair and used for binding an insert port of the bare metal node for deployment, at this time, a dhcp broadcast needs to be sent to obtain IP address allocation at the mac position of the bare metal node, the initial information of the bare metal node is a preset vlan number, all the initial information of the bare metal node on the soft gateway node can be set to be the same, as long as the soft gateway node detects a new bare metal node on the switch through a physical network card, the initial information is determined to be a preset vlan number, at this time, the patch interface does not use port security setting for the lower open representative port, all traffic is released, and the preset vlan number can be set to 4051. After initial information is sent to a deployment service through a soft bridge and a common bridge, the deployment service learns that a new bare metal node exists to be deployed, communication deployment information of the bare metal node is determined by obtaining dhcp information, the communication deployment information is a communication vlan number with a value different from a preset vlan number and is also different from communication vlan numbers of other configured bare metal nodes connected to a local soft gateway node, the bare metal node is deployed through the communication deployment information, and after deployment, the bare metal node performs conventional communication through the communication deployment information.
It can be understood that, in the above deployment process, the open representative port of the bare metal node on the soft gateway node and the port of the deployment service belong to the same network segment, so that the bare metal node can be ensured to normally communicate with the deployment service after passing through the physical network card, the soft bridge and the ordinary bridge.
It can be understood that, in this embodiment, the open representative port of the bare metal node belongs to a local port relative to the soft gateway node, that is, the traffic sent out by the port is not allowed to go out of the soft gateway node, and since the open representative port and the deployment service correspond to the same soft gateway node, the deployment service performs one-by-one initialization deployment on the bare metal nodes detected on the local soft gateway node, and a situation that communication deployment information of a plurality of bare metal nodes is the same or a situation that a communication path is sent out to cause deployment of a bare metal node on another soft gateway node does not occur.
Further, specifically, the process of communication between the deployed bare metal node and the overlay network includes:
acquiring first communication information of the deployed bare metal nodes through a physical network card, and sending the first communication information to an overlay network card through a soft network bridge and a common network bridge in sequence, so that the overlay network card sends the first communication information to corresponding nodes in an overlay network;
and acquiring second communication information, which is sent by any node in the overlay network and corresponds to the deployed bare metal node, through the overlay network card, and sending the second communication information to the physical network card through the common network bridge and the soft network bridge in sequence, so that the physical network card sends the second communication information to the deployed bare metal node.
It can be understood that the deployed bare metal nodes communicate with communication vlan numbers, each bare metal node has a respective normal representative port, and is applied to a patch interface pair that belongs to itself when passing through a normal bridge and a soft bridge, and the home definition is performed with the communication vlan number, each bare metal node has a certain mac and ip, for example, the communication vlan number of the bare metal node bm1 is vlan =100, the corresponding patch interface pair includes v-bm1 and repr-bm1, the communication vlan number of the bare metal node bm2 is vlan =101, and the corresponding patch interface pair includes v-bm2 and repr-bm2. The communication vlan numbers of each bare metal node after deployment are different, so that the bare metal nodes cannot be directly communicated through an exchanger, the patch interface pairs are different, the communication vlan numbers are used for distinguishing, and the communication between any bare metal node and other objects must pass through a physical network card, a soft gateway, a corresponding patch interface pair and a common bridge, and then the communication is forwarded to a corresponding node position by the common bridge.
As shown in fig. 3, taking communication between a bare metal node bm1 and an overlay network as an example, the bare metal node bm1 sends first communication information to the overlay network, and then a physical network card in a soft gateway node receives the first communication information, determines a patch interface pair v-bm1 and a repr-bm1 according to a vlan number, and sends the first communication information to the overlay network card by the normal bridge after passing through the soft bridge, the patch interface pair v-bm1 and repr-bm1 and the normal bridge, and the overlay network card forwards the first communication information to a node at a corresponding position in the overlay network, where the node includes other soft gateway nodes, bare metal nodes, virtual machines, and the like; correspondingly, when any node in the overlay network sends second communication information corresponding to the bare metal node bm1, the overlay network card receives the second communication information, and after the second communication information is coupled to the repr-bm1, the v-bm1 and the soft network bridge through the common network bridge and the patch interface, the soft network bridge sends the second communication information to the physical network card, and the physical network card sends the second communication information to the bare metal node bm1.
The communication between the bare metal node bm2 and the overlay network is the same.
Further, even if the bare metal nodes belonging to the same soft gateway node are the same, because communication vlan numbers are different, communication traffic needs to be forwarded by the soft gateway node, and cannot be directly communicated through a bottom-layer-connected switch, specifically, communication between the bare metal nodes bm1 and bm2 takes the case that the bare metal node bm1 sends third communication information to bm2, a physical network card in the soft gateway node receives the third communication information and forwards v-bm1 and repr-bm1 to a common network bridge through a soft network bridge and a patch interface, the common network bridge sends the third communication information to the physical network card after passing through the patch pair repr-bm1 and v-bm1 and the soft network bridge, and the physical network card sends the third communication information to the bare metal node bm2 according to the communication vlan number of a target object.
Therefore, the patch port on the normal bridge is externally equivalent to a normal port in the overlay network, and can perform normal communication with other ports. It can be understood that in the above description, the bare metal node implements control of the network configuration security group, qos, and floating IP through open representative port and normal representative port. The embodiment provides pure software for providing a two-layer network agent for a soft gateway node, and can provide network configuration management (security group, qos and the like) and overlay tunnel encapsulation for a bare metal node, so that the bare metal node has the same network function as a virtual machine, and the competitiveness of a cloud product is increased.
Further, in this embodiment, an abnormal fault in the communication process may also be detected and located by the soft gateway node, and specifically, the control method further includes:
monitoring state information of the physical network card, the overlay network card, the soft network bridge and the common network bridge;
judging whether all the state information has abnormality or not;
if so, corresponding safeguard measures are taken according to the abnormal conditions.
Wherein, before taking corresponding safeguard measures according to the abnormal condition, the method further comprises the following steps:
determining abnormal conditions according to the abnormal state information; the abnormal conditions include: the method comprises the following steps of detecting the abnormality of a physical network card, and/or the abnormality of a network agent of a soft gateway node, and/or the abnormality of the connection of other nodes in an overlay network.
Further, when the abnormal condition is the network proxy abnormality of the soft gateway node, the process of taking corresponding safeguard measures according to the abnormal condition includes:
and the current deployment of all bare metal nodes of the soft gateway node is unbound, so that the bare metal nodes bind any other soft gateway node with brand-new deployment information different from the current deployment.
Furthermore, due to the occurrence of abnormal conditions, the reasons are not limited to the current soft gateway node, and at this time, the abnormal conditions can be reported to the manager node, and the manager node further comprehensively studies and judges network faults and determines safeguard measures.
It can be understood that, for the detection of the physical network card abnormality, the problem of the physical network card or the switch is usually found in time by judging the link state of the physical network card. Specifically, the soft gateway bridge can find out whether the physical network card is abnormal in time by monitoring the change of the bridge interface. And after the exception is found, continuously monitoring at intervals for 5 times, and reporting the report to the manager node neutron-server to transfer all binding bare metals of the soft gateway node. The existence of the physical network card is generally caused by manual operation of operation and maintenance personnel, so that the cache time of the network card changed by a user is given, and the condition that the physical network card is not added after the user removes the physical network card is prevented.
Furthermore, information forwarding on the soft gateway node depends on a network agent, the network agent comprises modules such as a soft network bridge and a common network bridge, and the bare metal soft gateway is ensured to be really effective by monitoring the state of the network agent of the node. When the network agent is found to be abnormal, the network agent is judged to be a middle-level fault and reported to the manager node, the manager node and the manager node are used for studying and judging whether the network agent is a uniformly dependent other service fault or a single-node fault, and if the single-node fault is caused, all the bound bare metal nodes of the soft gateway node need to be transferred.
Furthermore, the connection abnormality with other nodes in the overlay network is mainly communication detection abnormality with other soft gateway nodes, and the abnormality is data plane detection and aims to ensure that an actual data plane is normal. When communication detection is abnormal, the communication detection is judged to be low-level fault, and the manager node neutron-server comprehensively studies and judges the communication conditions of other soft gateway nodes, because the link through which the data really used by the bare metal soft gateway passes cannot be accurately determined, the migration is carried out only if the communication conditions of other soft gateway nodes are completely better than that of the current soft gateway node.
It can be understood that the abnormal condition is researched and judged by the manager node, and the manager node changes the soft gateway node bound by bare metal after each soft gateway node reports the manager node if a fault exists, so that judgment and contention among all soft gateway nodes can be avoided.
It can be understood that the mode of rebinding switching deployment is adopted, namely when the bare metal node changes the bound soft gateway node, the communication vlan number is changed to be different from the original vlan number, the use of the vlan number used before is avoided, and even if misjudgment occurs, namely a plurality of soft gateway nodes bind one bare metal node, a loop cannot occur, and the bare metal node can normally work.
Further, in this embodiment, the specific situations of preventing loops include: when the service network is abnormal and the management network is abnormal, the bare metal soft gateway configuration can be remained, and the service network is abnormal, so that other service networks cannot be influenced; when the service network is abnormal and the management network is normal, the soft gateway node is removed through the manager node, and the abnormality can be eliminated; the service network is normal, the management network is abnormal, and the original configuration of the soft gateway node is remained at this time, but because the vlan number of the bare metal node is changed, the soft gateway node does not forward the information of the bare metal node any more. Specifically, if a vlan configured and used by a residual bare metal node (identified as bmA) is bound by another bare metal (identified as bmB), bare metal bmB flow enters the soft gateway node, and if port security is configured by bmA, the flow of the bmB is discarded, and a service network is not affected; if the bmA is not port-safe, then the flow of bmB is possible.
According to the method and the device, the soft gateway node has the function of providing deployment service for the bare metal node by establishing the connection relation of the internal information of the soft gateway node, and the soft gateway node is externally embodied with the characteristics same as the virtual machine, so that the bare metal node can realize the network functions same as the virtual machine through the soft gateway node, including communication with an overlay network, setting of security groups, qos, distributed floating IP and the like.
