1. Installation and Configuration

Master

""" 1. Installing Salt-master Yum Install Salt-master 2. Modify the configuration file:/etc/salt/master interface:0.0.0.0 # Indicates the IP of master 3. Start Service Salt-master Start """

Minion:

""" 1. Installing Salt-minion Yum Install Salt-minion 2. Modify the configuration file/etc/salt/minion MASTER:192.168.1.100 # Master's address Or Master -192.168.1.4 -192.168.1.5 Random_master:true Id:peng # The unique ID that the client displays in Salt-master 3. Start Service Salt-minion Start """

2. Authorization

Master

""" Salt-key-l # View authorized and unauthorized slave Salt-key-a salve_id # Accept the salve of the specified ID Salt-key-r salve_id # denies the salve of the specified ID salt-key-d salve_id # Delete The salve of the specified ID """

3. Execution of commands

To remotely operate the salve on the master server:
1) Shell-based command

Salt ' peng ' cmd.run ' ifconfig '

2) The Salt API-based approach

Import Salt.client

Local = Salt.client.LocalClient ()

result = Local.cmd (' Peng ', ' cmd.run ', [' ifconfig '])
