Description

A method for collecting cluster server information

technical field

The invention discloses an information collection method, relates to the field of cluster server management, in particular to a cluster server information collection method.

Background technique

Various information of the computer is stored in the server, and the management and maintenance of the server are very important. The server needs to obtain various files of the server during management and maintenance, such as system log information to analyze the status of the server. For small clusters, this is not very time-consuming and laborious. However, for larger clusters, the server has many nodes. If you use the usual Method It takes a lot of time and energy to copy the information of each node through the U disk or the scp command, and a lot of repetitive work. The present invention provides a kind of cluster server information collection method, this method realizes the operation of inputting IP address, user name and password in scp remote copying process together through expect tool and shell script, executes this script afterwards and can finish copying operation, does not need in the execution process Manually enter other system commands and perform other operations. The method of the invention is convenient to use, simple to operate, can be completed without professional knowledge, saves manpower and time, and improves work efficiency.

expect for Windows is a powerful expect tool under the Windows platform for system management and automated testing. expect uses Tcl as the language core. Tcl is actually a library of subroutines that can be embedded in programs to provide language services. Not only that, Expect can be used regardless of whether the program is interactive or non-interactive.

Contents of the invention

Aiming at the needs and deficiencies of the current technological development, the present invention provides a cluster server information collection method, using this method only needs to select a node, copy the script to the node, and then execute the script to collect the information of all nodes The log information is copied to this node and named according to the serial number.

A method for collecting cluster server information:

Select a node of the cluster server, save the parameter information of each node in the configuration file, copy the information collection script to the selected node, execute the information collection script to extract the parameter information of each node in the configuration file, and call the expect tool to realize The parameter information of each node is automatically input, and the information collection script is executed to copy the file information of all nodes to the selected node and name it according to the serial number.

The information collection script is edited using a shell script.

Execute the scp command in the information collection script, use remote operation to copy the file information of all nodes to the selected node and name them according to the serial number.

The parameter information of each node includes an ip address, a user name and a password, and a file name to be copied.

The specific operation steps of the cluster server information collection method are as follows:

S1 selects a node of the cluster server,

S2 edits the configuration file, and saves the parameter information of each node in the configuration file;

S3 copies the information collection script to the selected node,

The S4 information collection script is automatically executed to obtain the configuration document information, and call the expect tool to automatically input the parameter information of each node.

S5 executes the information collection script to copy the file information of all nodes to the selected node and name it according to the serial number.

The parameter information of the node in the configuration file is written in the following format: IP username password.

Enter the command as follows when executing the information collection script: ./copy.sh configuration file path node target file path/local save path.

The beneficial effect that the present invention has compared with prior art is:

Utilize the method of the present invention to select a certain node of the cluster server, save the parameter information of each node in the configuration file, copy the information collection script to the selected node, execute the information collection script to extract the parameter information of each node in the configuration file, and Call the expect tool to automatically input the parameter information of each node, execute the information collection script to copy the file information of all nodes to the selected node and name them according to the serial number; this method further uses the shell script and the expect tool to realize the file copy operation of the cluster server , can be applied to cluster server products of all linux systems, facilitates the maintenance and management of cluster servers, and greatly simplifies the operation process, especially for personnel without relevant experience, this method can easily complete the task, and is used in the management and maintenance of cluster servers , save time and improve efficiency.

detailed description

The present invention provides a cluster server information collection method: select a certain node of the cluster server, save the parameter information of each node in the configuration file, copy the information collection script to the selected node, execute the information collection script to extract the configuration file The parameter information of each node, and call the expect tool to realize the automatic input of the parameter information of each node, execute the information collection script to copy the file information of all nodes to the selected node and name it according to the serial number.

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific examples.

Take a cluster server as an example, select one of the servers as the node for copying file information, and save the parameter information such as node ip address, user name and password, and file name to be copied in the configuration file of each node;

Copy the shell script to the selected node, execute the shell script to extract the parameter information of each node in the configuration file, and call the expect tool to realize the automatic input of the ip address, user name and password of each node, and execute the scp command in the shell script for remote operation Copy the file information of all nodes to the selected node and name it according to the serial number.

The specific operation steps are:

S1 selects a node of the cluster server,

S2 Edit the configuration file configure.list, save the parameter information such as the ip address of each node, user name and password, and the file name to be copied in the configuration file; wherein the parameter information is written in the following format: IP usernamepassword, with spaces or tab keys in the middle To separate, the information of multiple hosts needs to write multiple lines, such as:

192.168.0.10root 12345678

192.168.0.20user passw0rd

S3 copies the shell script to the selected node,

The S4shell script is automatically executed to obtain the configuration document information, and call the expect tool to automatically input the parameter information of each node.

Enter the command in the following way during execution: ./copy.sh/configuration document path/node target file path/local save path, for example: ./copy.sh./configure.list/var/log/messages/tmp

S5 executes the shell script to copy the file information of all nodes to the selected node and names them according to the serial number.

The code of the script part of the above process is as follows:

Execute the script:

The expect script is used to execute the automatic input of user name and password as follows:

Use this method to use shell script and expect tool to realize the file copy operation of the cluster server, which can be applied to the cluster server products of all linux systems, facilitates the maintenance and management of the cluster server, and greatly simplifies the operation process, especially for those who have no relevant experience. Using this method can easily complete tasks, and when used in the management and maintenance of cluster servers, it saves time and improves efficiency.
