This article will explain in detail about the use of linux pssh command batch management implementation, the editor thinks it is very practical, so share it for you to do a reference, I hope you can get something after reading this article.

Pssh is an open source software implemented in python, which is used for batch ssh to operate a large number of machines; pssh is a tool that can execute commands on multiple servers and supports copying files, which is excellent among similar tools; I recommend pssh more than the for loop! The premise for using pssh is that key authentication access (that is, ssh trust relationship) must be configured on the local machine and other servers.

Syntax format: pssh [parameters] [file]

Common parameters:

Reference example

Batch execute commands:

[root@linuxcool] # pssh-h hosts.txt-l root-I 'uptime'

If you add the-A parameter, you will be prompted for a password even if the ssh trust relationship is done in advance:

[root@linuxcool ~] # pssh-h hosts.txt-l root-I-A 'uptime' about batch management and execution using linux's pssh command is here. I hope the above content can be of some help and learn more knowledge. If you think the article is good, you can share it for more people to see.
