Saltstack (vii) Configuration management system initialization init

Saltstack Configuration Management sub-environment management:
①.base is a basic environment that typically stores configuration management information that is used by all servers.
②.dev for developing test environments, it is common to store configuration management information that is used by the development test server.
③.pro is an online environment that typically stores configuration management information used by online servers.
The state file entry for Saltstack configuration management is Top.sls, and it is recommended that you configure one Top.sls file per environment.

Saltstack System Initialization Practical case:
1. Modify the master configuration file on the Node1 to define the base environment.

Base 2 ^file_roots/etc/salt/master file_roots:  base:    -/srv/salt/Base 

2. Write the state file, and the final directory tree looks like this:

Base]   # tree/srv/salt/Base//srv/salt/base/├──init│├──dns.sls│├──env_init.sls│├──files││ ├──hosts││└──zabbix_agentd.conf│├──history.sls│├──sysctl.sls│└──zabbix_agent.sls└──top.sls2  8 files

Details of the 3.state file:
* Note: Because of too many configuration files, the direct definition in the Top.sls file is too bloated, so defined a Env_init.sls file, all the state files include, see the last file content.

4. The state file for configuration management is executed on the master side of the Node1, which can be executed before the test is passed.

[[email protected] ~]# Salt ' * ' state.highstate env=base Test ---Add the test parameter, the simulation performs the operation, does not actually execute.
[[email protected] ~]# Salt ' * ' state.highstate env=base
