Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a method for maintaining a Linux cluster according to an embodiment of the present application. The execution main body of the method for maintaining the Linux cluster is a maintenance server in the Linux cluster. The method for maintaining the Linux cluster as shown in fig. 1 includes S101 to S104. The details are as follows:
s101, obtaining a maintenance command and loading information of a plurality of cluster servers.
In this embodiment, the maintenance server obtains the maintenance command and loads information of a plurality of cluster servers. The maintenance command is a command or a command set used for performing a maintenance operation on the cluster server, and includes, but is not limited to, a change command, an upgrade command, a software installation command, and the like, and may be a secure Shell protocol SSH command or a Shell script written by the SSH command. Wherein the SSH command can be sent to the maintenance server through a command window of an SSH tool (such as Putty, Xshell 5, Bitvise SSH Client, etc.) to be received by the maintenance server; shell scripts can be uploaded to the maintenance server through SSH tools.
The cluster server information is server information in the Linux cluster, and includes, but is not limited to, a server name, a server IP address, an account and a password required for logging in the server, a service project name to which the server belongs, information of a machine room in which the server is located, and the like. Among them, Linux is known as GNU/Linux, which is a free-running and freely-spreading UNIX-like operating system capable of running major UNIX tool software, application programs and network protocols, and Linux has hundreds of different releases, such as centros, Debian, ArchLinux based on community development, and Red Hat Enterprise Linux, SUSE, Oracle Linux based on commercial development, and the like. It can be understood that, depending on the business project, there may be a plurality of Linux clusters, and each cluster may include hundreds of servers. Illustratively, an SSH command is written into a Shell script, the Shell script is uploaded to a maintenance server through an SSH tool, and after the Shell script is obtained by the maintenance server, server information of a plurality of Linux clusters can be loaded according to business project names.
S102, filtering the information of the cluster servers to obtain the server information of the command execution servers.
In this embodiment, the system administrator previously logs in each Linux server needing maintenance through the SSH tool to execute the command, and as the number of the maintenance servers increases, the maintenance workload becomes larger and larger. Therefore, in this embodiment, the information of the plurality of cluster servers is filtered according to the preset filtering condition, so as to screen out the server information of the server executing the maintenance command. The preset filtering condition includes, but is not limited to, whether it is a preset server name, whether it is an Internet Protocol (IP) address of a preset server, whether it belongs to a preset machine room, and whether it belongs to a preset service project.
The command execution server is a server in the cluster that needs maintenance. For example, if the service logic in the policy service is changed, the server responsible for the policy service may be found from the plurality of cluster servers, and then one or more servers responsible for the corresponding service logic may be found from the server responsible for the policy service, and the server may be used as a command execution server.
In an embodiment, the cluster server information includes server IP addresses, and then, according to a preset IP address filtering condition, the cluster servers corresponding to the server IP addresses meeting the IP address filtering condition are used as command execution servers, and the server information of the command execution servers is obtained. Since the IP address of the server is unique, the server which needs to be ordered is screened out according to the IP address which needs to be maintained, so that the accuracy of the screening result is improved. The preset IP address filtering condition may be an IP address of a server to be maintained, which is sent to the maintenance server by the SSH tool in advance.
And S103, combining the maintenance command and the server information of the command execution server to generate a maintenance command execution work order.
In this embodiment, the maintenance command execution work order is a task work order of the maintenance server scheduling command execution server, and may include an SSH command execution work order or a Shell script execution work order according to different command forms. When the maintenance command is an SSH command, combining the SSH command with server information of a command execution server to generate an SSH command execution work order; and when the maintenance command is the Shell script, combining the Shell script with the server information of the command execution server to generate a Shell script execution work order.
It can be understood that different scheduling modes can be set for the command execution server according to different maintenance requirements, that is, the maintenance command execution work order can also include the scheduling mode of the command execution server. The scheduling mode can be a sequential scheduling mode and a parallel scheduling mode, the sequential scheduling mode is that the command execution server is sequentially scheduled according to a preset sequence to sequentially execute the SSH command or the command in the Shell script, and the parallel scheduling mode is that the command execution server is concurrently scheduled to concurrently execute the SSH command or the command in the Shell script. Illustratively, the SSH tool sends the maintenance command and the scheduling mode to the maintenance server together, so that the maintenance server generates a command execution work order by combining the maintenance command, the server information of the command execution server and the scheduling mode after screening out the command execution server. If the scheduling method is not specified, the maintenance server executes the maintenance command according to the scheduling command execution server of the default scheduling method.
And S104, executing the work order according to the maintenance command, and scheduling a plurality of command execution servers to execute the maintenance command.
In this embodiment, since the maintenance command execution work order includes the server information of the command execution servers, the command execution servers can be logged in batch according to the server information of the plurality of command execution servers in the maintenance command execution work order, and after logging in each command execution server, the maintenance server issues the ssh command to each command execution server for execution, so as to schedule the plurality of command execution servers for execution.
The embodiment of the application provides a method for maintaining a Linux cluster, which is characterized in that the information of a plurality of cluster servers is filtered by acquiring a maintenance command and loading the information of the cluster servers to obtain the server information of a plurality of command execution servers, so that the maintenance server can quickly screen out the command execution servers from a plurality of servers in the cluster and acquire the server information of each command execution server, and the server information can comprise a password for logging in a corresponding server, so that the maintenance server can log in the command execution servers in batches, and the maintenance efficiency of the Linux cluster is improved; and combining the maintenance command and the server information of the command execution server to generate a maintenance command execution work order, executing the work order according to the maintenance command, scheduling the command execution servers to execute the maintenance command to obtain the command execution work order, thereby providing feasibility for the maintenance server to schedule the command execution servers to execute the maintenance command concurrently in a parallel scheduling mode, and further improving the maintenance efficiency of the Linux cluster.
Referring to fig. 2, fig. 2 is a flowchart illustrating an implementation of step S104 in a method for maintaining a Linux cluster according to an embodiment of the present application. With respect to the embodiment corresponding to fig. 1, step S104 of the method for maintaining a Linux cluster provided in this embodiment includes steps S201 and S202. The details are as follows:
s201, according to the server information of a plurality of command execution servers in the maintenance command execution work order, the command execution servers are logged in batch.
In this embodiment, the general process of logging in the command execution server through the SSH tool is as follows: firstly, executing a command SSH username @192.168.1.x, wherein the system prompts whether to continue to connect for the first login, then 'yes' can be input in a command window of the SSH tool, and then after a period of time, the system prompts to input a password, and then a correct password can be input in the command window of the SSH tool to log in the command execution server. Therefore, the manual login process has two times of man-machine interaction, wherein one time is to input 'yes' and the other time is to input a password, the man-machine interaction is changed into automatic interaction, and the automatic interaction can be realized through a pexpect module of python.
S202, after logging in each command execution server, scheduling a plurality of command execution servers to execute maintenance commands.
In this embodiment, after logging in each command execution server, scheduling a plurality of command execution servers to execute a maintenance command includes: after logging in each command execution server, scheduling a first preset number of command execution servers each time and executing the maintenance commands until the execution of the maintenance commands is completed.
Because the Linux cluster has a load value and the number of servers to be maintained exceeds the load value that the Linux cluster can bear, in order to avoid Linux overload caused by scheduling too many servers concurrently to execute the maintenance command, the first preset number of command execution servers are scheduled each time to concurrently execute the maintenance command until the command execution servers in the command execution work order complete the execution of the maintenance command. It is understood that the specific value of the first preset number may be set according to an actual load value of the Linux cluster.
In one possible implementation manner, scheduling a first preset number of command execution servers at a time and executing the maintenance command concurrently includes: scheduling a first preset number of command execution servers each time, and connecting the command execution servers into a star model, wherein each command execution server is a connection node on the star model; and taking the central node of the star model as a starting point, and sequentially transmitting the maintenance command to each connecting node on the star model according to the connection sequence of the star model so that the command execution server corresponding to each connecting node executes the maintenance command.
In this embodiment, the star model is a transmission model for transmitting a maintenance command to the command execution server in a star manner, and is mainly used to implement upgrading, maintenance, querying, and detecting system configuration information. Specifically, the command execution servers deployed in different areas are connected into a star, the star takes one command execution server or a maintenance server as a star center, and other command execution servers are connected with the star center.
Illustratively, the first preset number is 32, 32 command execution servers are scheduled each time, one of the command execution servers is used as a star hub, and the other 31 command execution servers are connected with the star hub to form a star model. When the maintenance server issues the maintenance command to the command execution server, the maintenance command is sent to the star center, and then the maintenance command is sent to the other 31 command execution servers at the same time, so that the command execution server concurrently executes the maintenance command, and the maintenance efficiency of the Linux cluster is improved. It will be appreciated that for less than 32 cases of command execution servers, the maintenance server still connects the command execution servers into a star model.
In another possible implementation manner, scheduling a first preset number of command execution servers at a time and executing the maintenance command concurrently includes: scheduling a first preset number of command execution servers each time, and connecting the command execution servers into a tree model, wherein each command execution server is a connection node on the tree model; and taking the root node of the tree model as a starting point, and sequentially transmitting the maintenance command to each connecting node on the tree model according to the connection sequence of the tree model so that the command execution server corresponding to each connecting node executes the maintenance command.
In this embodiment, for maintenance commands such as a pulling command of a Docker image, a database installation command, a deployment command, an upgrade command, and the like, which carry data such as an image, an installation package, and the like, such maintenance commands need to instruct an execution server to receive the image or the installation package during execution, and if a traditional concurrency mode is adopted, network bandwidth is occupied at the moment of parallel execution, which greatly affects existing services. Therefore, in order to reduce the occupation of network bandwidth resources, the present embodiment connects the command execution servers as a tree model, which is a transmission model for transmitting the maintenance command to the command execution servers in a tree manner.
Specifically, the star type uses one command execution server or a maintenance server as a tree root, and other command execution servers are connected in sequence at an execution level of the command execution server, wherein the execution level of the command execution server is, for example, an installation command of a database, and the execution level of the command execution server executes the order of the installation command for each command execution server. It is understood that each node in the tree model may have a sub-node, that is, the next node, such as the root node, may have two or more command execution servers, that is, after the root node, two or more command execution servers are required to execute the maintenance command simultaneously.
Further, after scheduling a first preset number of command execution servers and executing the maintenance commands concurrently each time, the method further includes: if the load value of the Linux cluster is larger than the preset threshold value, scheduling a second preset number of command execution servers to execute the maintenance commands and executing the maintenance commands, wherein the second preset number is smaller than the first preset number; and if the load value of the Linux cluster is smaller than the preset threshold value, scheduling a third preset number of command execution servers to execute the maintenance commands in parallel, wherein the third preset number is larger than the first preset number.
In this embodiment, since there are a plurality of Linux clusters, the number of servers in each cluster is not necessarily the same, that is, the load value of each cluster is not necessarily the same. Therefore, for a cluster with a high load value, when a first preset number of command execution servers are scheduled, the load value of the cluster is greater than a preset threshold value, so that the cluster is overloaded, the cluster is subjected to balanced load, the phenomenon that the server is down due to the overload of the cluster is avoided, the execution process of the maintenance command is prevented from being influenced, and the safety of the execution process of the maintenance command is improved.
In all embodiments of the present application, the corresponding command execution work order is obtained based on the maintenance command and the server information of the command execution server, and specifically, the command execution work order is generated by combining the maintenance command and the server information of the command execution server. Uploading the command execution work order to the blockchain can ensure the safety and the fair transparency of the user. The command execution server can download the command execution work order from the blockchain so as to check whether the server information of the maintenance command and the command execution server is tampered. The blockchain referred to in this example is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, and the like. A block chain (Blockchain), which is essentially a decentralized database, is a series of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate a next block. The blockchain may include a blockchain underlying platform, a platform product service layer, an application service layer, and the like.
