Abstract

The invention discloses a method for automatically copying files to each node of a cluster server, which belongs to the field of copying files to each node of a cluster server. The technical problem to be solved by the invention is that the efficiency of copying files to each node of a cluster server is low, and the technical solution adopted The steps are: (1) Set the configuration document information through the shell script. After configuration, the document information includes the IP address, user name and password of each node; (2) Execute the shell script and call the except tool, and input the document path and local source file path through the scp command and the target file path of the remote host; (3) The shell script is automatically executed to obtain the configuration file information and execute the copy; (4) Display the execution process.

Description

A method for automatically copying files to each node of a cluster server

technical field

The invention relates to the field of copying files to each node of a cluster server, in particular to a method for automatically copying files to each node of a cluster server.

Background technique

There are many cluster server nodes. When you want to copy some files or scripts to each node during the test, if you use a USB flash drive or manually enter the scp command to copy the nodes one by one, you need to do a lot of repetitive work such as user name and password input, which takes a lot of time. How to realize the operation of copying files to other nodes by simply selecting a node, copying the file to be copied together with the script to the node, and then executing the script is the technical problem to be solved by the present invention.

Contents of the invention

The technical task of the present invention is to provide a method for automatically copying files to each node of the cluster server to solve the problem of low efficiency of copying files to each node of the cluster server.

Technical task of the present invention is realized in the following manner:

A method for automatically copying files to each node of a cluster server, the steps are:

(1) Set the configuration file information through the shell script. After configuration, the file information includes the IP address, user name and password of each node;

(2) Execute the shell script and call the except tool, and input the document path, local source file path and remote host target file path through the scp command;

(3) The shell script is automatically executed to obtain the configuration file information and execute the copy;

(4) Display the execution process.

When setting the configuration document information in the step (1), the information format of the IP address, user name and password of each node is:

IP username password

The ip address and user name and the user name and password are separated by spaces or tab keys.

Enter the command when executing the script in step (2):

./batch_scp.sh configuration document path local source file path remote host target file path.

The principle of the present invention is: use shell script to extract information such as node ip address, user name and password in the configuration file, then execute the scp command and call the expect tool to realize the automatic input of the node's password in the scp remote operation process, eliminating the need for human-computer interaction process.

A method for automatically copying files to each node of the cluster server of the present invention has the following advantages: the present invention adopts shell script and expect tool to realize the operation of automatically copying files to each node of the cluster server, which greatly simplifies the operation process, especially for those who do not have relevant Experienced personnel can easily complete the copying task by using this method. The method can conveniently complete a large number of copying tasks during the testing and use stages of the cluster server, saving time and improving efficiency.

Description of drawings

The present invention will be further described below in conjunction with the accompanying drawings.

Accompanying drawing 1 is the schematic flow chart of shell script in the embodiment.

detailed description

A method for automatically copying files to each node of the cluster server according to the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Example:

A method for automatically copying files to each node of the cluster server according to the present invention, the steps are:

(1) Set the configuration file information through the shell script. After configuration, the file information includes the IP address, user name and password of each node;

(2) Execute the shell script and call the except tool, and input the document path, local source file path and remote host target file path through the scp command;

(3) The shell script is automatically executed to obtain the configuration file information and execute the copy;

(4) Display the execution process.

The shell script completes the following functions:

(1) Manually complete the configuration file cfg.list

Specify the remote host ip, user name and password in the configuration file cfg.list. These information need to be written in the following format:

IP username password

The middle is separated by a space or a tab key, and the information of multiple hosts needs to be written in multiple lines, such as:

192.168.0.1root123456

192.168.0.2userpassword

(2) Execute the script

When executing, enter the command in the following way:

./batch_scp.sh configuration document path local source file path remote host target file path

For example:

./batch_scp.sh ./cfg.list/root/file/root/file

(3) Complete the copy operation and display it on the screen

During the execution of the script, the copy process will be displayed on the screen, and the copied file information can be viewed according to the display.

Through the above specific implementation manners, those skilled in the technical field can easily realize the present invention. However, it should be understood that the present invention is not limited to the specific embodiments described above. On the basis of the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions. Except for the technical features described in the description, all are known technologies by those skilled in the art.
