Saltstack is a centralized and lightweight automated O & M management tool with puppet and func functions. It is written in Python and has powerful functions and can be quickly installed using epel. Compared with puppet, installation and configuration are easier and easier.

 

Epel install

[[email protected] ~]# rpm -Uvh  http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm###CentOS 5.x###rpm -Uvh https://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm

 

1. Install salt-master (only installed on Master hosts)

[[Email protected] ~] # Yum-y install salt-master salt #### salt-minmion managed machine ### [email protected] ~] # Yum-y install salt-minion

 

2. Configure saltstack
