Referring to fig. 1 and fig. 2, fig. 1 is a schematic flowchart of a method for creating a Linux virtual server according to an embodiment of the present application, and fig. 2 is an interaction schematic diagram of the Linux virtual server and a management platform according to the embodiment of the present application. The Linux virtual server creating method is used for creating a Linux virtual server 21 in a Linux virtual server cluster. The Linux virtual server cluster includes a plurality of Linux virtual servers 21, and the plurality of Linux virtual servers 21 may be deployed on the same physical machine 20 or on a plurality of physical machines 20, which is not limited herein.
It should be noted that fig. 2 only illustrates the interaction between one physical machine 20 and the management platform 10, and the interaction between the other physical machines 20 and the management platform 10 is similar to that in fig. 2 and is not necessarily depicted. In addition, it is understood that the management platform 10 may be installed in a server of hardware.
As shown in FIG. 1, the Linux virtual server creating method comprises steps S101 to S105.
S101, receiving a creation request sent by a management platform, wherein the creation request comprises a software image identifier.
In this embodiment, when a new Linux virtual server 21 needs to be created in the Linux virtual server cluster, a user such as a developer or a maintainer may send an add Linux virtual server request to the management platform 10, so that the management platform 10 sends a creation request to the physical machine 20 when receiving the add Linux virtual server request. Wherein the creation request includes a software image identification. The software image identifier is an identifier corresponding to the software image in the image repository.
It should be noted that the software image identifier may be an identifier used for uniquely identifying the software image, such as a name and a number of the software image, and specific content of the software image identifier is not limited herein.
S102, acquiring a corresponding software image according to the software image identification, and creating a corresponding container according to the software image, wherein the software image comprises a Linux virtual server and routing software, and the Linux virtual server and the routing software are operated in the container.
In this embodiment, the physical machine 20 may acquire the software image pre-stored in the image repository according to the software image identifier. Two kinds of software, Linux virtual server 21 and routing software, are included in the software image. That is, the Linux virtual server 21 and the routing software are placed in one image.
After acquiring the software image, the physical machine 20 creates a container corresponding to the Linux virtual server 21 and the routing software by using the software image. After the container is created, the Linux virtual server 21 and routing software may be run in the container.
In one embodiment, physical machine 20 may obtain a software image by executing a Docker run command and create a corresponding container from the software image. For example, assuming that the software image is identified as "LVS-Qugga", the physical machine 20 may complete the operation of step S102 by executing the following commands: docker run LVS-Qugga.
In one embodiment, the routing software may be a Qugga software, and the generated container may be a Docker container. Of course, in other embodiments, the routing software and the container may be of other types, and the types of the routing software and the container are not limited herein.
S103, receiving the container network addresses distributed to the containers by the management platform and the virtual network addresses distributed to the Linux virtual servers, wherein the container network addresses of all the containers in the Linux virtual server cluster are different from each other, and the virtual network addresses of all the Linux virtual servers are the same.
In one embodiment, when the physical machine 20 successfully creates the container using the software image, a network address obtaining request is sent to the management platform 10, where the network address obtaining request includes the container creation success identifier and the identity information corresponding to the container. The identity information corresponding to the container may be a name, a number, or the like of the container for identifying the container. After receiving the network address acquisition request sent by the physical machine 20, the management platform 10 allocates a container network address to the container and allocates a virtual network address to the Linux virtual server 21 in the container, and sends the container network address of the container and the virtual network address of the Linux virtual server 21 to the physical machine 20. Meanwhile, the management platform 10 stores the correspondence between the identity information of the container and the container network address of the container, so that the management platform 10 manages the container network address of the container.
Of course, in other embodiments, the physical machine 20 may not send the network address obtaining request to the management platform 10, and the management platform 10 sends the container network address of the container and the virtual network address of the Linux virtual server 21 to the physical machine 20 after allocating the container network address to the container and allocating the virtual network address to the Linux virtual server 21, which is not limited herein.
The physical machine 20 receives the container network address assigned by the management platform 10 for the container and the virtual network address assigned for the Linux virtual server 21. It should be noted that, in this embodiment, because the Linux virtual server 21 runs in a container, a plurality of containers exist in the Linux virtual server cluster, one Linux virtual server 21 runs in each container, the container network address of each container is a private network address, the virtual network addresses corresponding to the Linux virtual servers 21 in all the containers in the Linux virtual server cluster are public network addresses, that is, in the Linux virtual server cluster, the container network addresses of each container are different from each other, and the virtual network addresses corresponding to the Linux virtual servers 21 in all the containers in the Linux virtual server cluster are the same, so that a plurality of Linux virtual servers 21 in the Linux virtual server cluster can work simultaneously, and the efficiency of processing requests by the Linux virtual server cluster is improved.
S104, configuring the container according to the container network address, and configuring the Linux virtual server according to the virtual network address.
After the physical machine acquires the container network address and the virtual network address, the network address of the container is configured as the container network address, and the network address of the Linux virtual server 21 is configured as the virtual network address.
Specifically, in one embodiment, physical machine 20 may configure the network address of the container as the container network address by executing a pipe command, and configure the network address of the Linux virtual server as the virtual network address by executing a Docker run command.
In this embodiment, the management platform 10 performs remote network address binding via an Angle command. Specifically, the management platform 10 starts the physical machine 20 to execute a pipe command and a Docker run command through the anchor command, and transmits a container network address and a virtual network address to the physical machine 20 through the anchor command. The physical machine 20 configures the network address of the container as the container network address by executing a pipeline command, and writes the virtual network address into the configuration file of the Linux virtual server 21 by executing a Docker run command, so that the Linux virtual server 21 can read the virtual network address in the configuration file at the subsequent start-up of the Linux virtual server 21 to complete the configuration of the network address.
In an embodiment, as shown in fig. 3 and fig. 4, fig. 3 is another schematic flowchart of a creating method of a Linux virtual server in an embodiment of the present application, and fig. 4 is an interaction schematic diagram of the Linux virtual server and a processing server in the embodiment of the present application. After step S104, steps S106 and S107 are also included.
S106, when the Linux virtual server is operated, reading a pre-stored configuration file, wherein the configuration file comprises the network address information and the port number of the processing server.
S107, loading the configuration file into a configuration directory of the Linux virtual server, so that the Linux virtual server communicates with the processing server through the network address information and the port number of the processing server.
After the container network address of the container and the virtual network address of the Linux virtual server 21 are configured in step S104, when the Linux virtual server 21 is running, the configuration file pre-stored in the physical machine 20 is read. The configuration file is a configuration file corresponding to the Linux virtual server 21, and the configuration file includes network address information and port numbers of the plurality of processing servers 30 managed by the Linux virtual server 21. The configuration file is then loaded into the configuration directory of the Linux virtual server 21. Thus, when the Linux virtual server 21 needs to send the received request to the processing server 30 for processing, the request can be forwarded to the corresponding processing server 30 according to the network address information and the port number of the processing server 30 in the configuration directory, so that the processing server 30 can process the request.
In an embodiment, the operating mode of the Linux virtual server 21 may be a DR operating mode, a VS/NAT mode, or a VS/TUN mode, which is not limited herein.
It should be noted that fig. 4 only illustrates the management relationship between some of the Linux virtual servers 21 and the processing servers 30, and it is understood that other Linux virtual servers 21 may also have a management relationship between the processing servers 30 illustrated in fig. 4, which is not necessarily illustrated herein.
In addition, in the creating method shown in fig. 3, step S105 and steps S106 and S107 are in parallel, but of course, in other embodiments, step S105 and steps S106 and S107 may also be in a sequential relationship, for example, step S104, step S106 and step S107 are executed in sequence, and then step S105 is executed; or the steps S104 and S105 are executed in sequence, and then the steps S106 and S107 are executed, where the sequence of the steps S105, S106 and S107 is not limited.
S105, establishing a neighbor relation between the container and the gateway through the routing software to generate a dynamic route in the gateway so as to complete the establishment of the Linux virtual server, wherein the dynamic route comprises a destination address and a next hop address, the destination address is a virtual network address corresponding to the Linux virtual server, and the next hop address is a container network address corresponding to the container.
In this embodiment, as shown in fig. 4, the physical machine 20 runs routing software in a container, and then establishes a neighbor relationship between the container and the gateway 40 through the routing software to generate a dynamic route in the gateway 40, thereby completing the creation of the Linux virtual server 21. The dynamic route includes a destination address and a next hop address, the destination address is a virtual network address corresponding to the Linux virtual server 21, and the next hop address is a container network address corresponding to the container.
When the gateway 40 receives a request sent by an external device, the gateway 40 may send the request to a container corresponding to a next hop address according to a dynamic route, and then the Linux virtual server 21 in the container matches with a destination address according to its own virtual network address. And if the matching is successful, processing the request. By adopting the Linux virtual server 21 created by the Linux virtual server creating method in the embodiment, a dynamic route can be established between each container in the Linux virtual server cluster and the gateway 40, and the gateway 40 can evenly distribute a plurality of requests to a plurality of containers, so that a plurality of Linux virtual servers 21 in the Linux virtual server cluster can work simultaneously, and the efficiency of processing the requests is improved. Meanwhile, when the number of the Linux virtual servers 21 in the Linux virtual server cluster is not enough to meet the request processing requirement, the creating method in the embodiment can be adopted to quickly add a new Linux virtual server 21 in the Linux virtual server cluster, so that the transverse expansion of the Linux virtual server 21 is realized, and the processing process of other Linux virtual servers 21 is not influenced.
In an embodiment, the establishing, by the routing software, a neighbor relation between the container and the gateway to generate a dynamic route in the gateway may specifically be: establishing, by the routing software and based on an OSPF protocol, a neighbor relation between the container and a gateway to generate a dynamic route in the gateway. As shown in fig. 4, the OSPF neighbor relationship is established between the container shown in fig. 4 and the gateway 40.
It should be noted that fig. 4 only illustrates the OSPF neighbor relationship between the container in which the Linux virtual server 21 is located and the gateway 40, and it is understood that the OSPF neighbor relationship is also established between the container in which other Linux virtual servers 21 are located and the gateway 40, which is not drawn herein.
Additionally, in other embodiments, the neighbor relationship between the container and the gateway 40 may also be established based on other protocols. For example, the neighbor relationship between the container and the gateway 40 may be established by the routing software based on the BGP protocol to generate dynamic routes in the gateway 40, which is not particularly limited herein.
In one embodiment, after establishing, by the routing software, a neighbor relation between the container and a gateway to generate a dynamic route in the gateway, the method further comprises: if the Linux virtual server is detected to be abnormally operated, sending a removal request to the management platform to enable the management platform to delete the Linux virtual server abnormally operated and the container where the Linux virtual server is located, and recovering the container network address of the container where the Linux virtual server abnormally operated is located.
Specifically, when the physical machine 20 detects that the Linux virtual server 21 is abnormally operated, a removal request may be sent to the management platform 10. After receiving the removal request, the management platform 10 may delete the Linux virtual server 21 running abnormally and the container in which the Linux virtual server 21 is located through the physical machine 20, and delete the correspondence between the identity information of the container in which the Linux virtual server 21 running abnormally is located and the container network address, so as to recover the container network address of the container in which the Linux virtual server 21 running abnormally is located, so as to allocate the container network address to other containers for use. Therefore, the Linux virtual server 21 with abnormal operation can be kicked out of the Linux virtual server cluster, and meanwhile, the working states of other Linux virtual servers 21 are not influenced.
The method for creating the Linux virtual server in the embodiment can quickly create the Linux virtual server 21 in the Linux virtual server cluster, and realize the transverse expansion of the Linux virtual server 21 so as to meet the requirement of the request processing quantity. Meanwhile, the Linux virtual server 21 created by the creating method can realize simultaneous work of a plurality of Linux virtual servers 21, and the efficiency of processing the request by the Linux virtual server cluster is improved.
