First, System initialization

1. Writing resolv.conf (DNS) files

[Email protected] init]# Cat/etc/salt/states/init/dns.sls

/etc/resolv.conf:

File.managed:

-Source:salt://init/files/resolv.conf

-User:root

-Group:root

-mode:644

2. Add time to Historical order (history)

[Email protected] init]# Cat/etc/salt/states/init/history.sls

/etc/profile:

File.append:

-Text:

-Export histtimeformat= "%F%T ' WhoAmI '"

3. Write command audit function

[email protected] init]# cat Audit.sls

/etc/bashrc

File.append:

-Text:

-Export prompt_command= ' {msg=$ (History 1 | {read x y; echo $y;}); Logger "[euid=$ (WhoAmI)]": $ (Who am I): [' pwd '] "$msg"; }‘

4. Changing kernel parameters

[email protected] init]# cat Sysctl.sls

Vm.swappiness:

Sysctl.present:

-value:0

Net.ipv4.ip_local_port_range:

Sysctl.present:

-value:10000 65000

Fs.file-max:

Sysctl.present:

-value:100000

5. Centralized management of the above 4 configuration files

[email protected] init]# cat Env_init.sls

Include

-Init.dns

-Init.history

-Init.audit

-Init.sysctl

6. Writing the Top.sls file

[Email protected] init]# CD.

[email protected] states]# cat Top.sls

Base

‘*‘:

-Init.env_init

7. Execute salt

[[email protected] states]# Salt ' * ' state.highstate test=true #模拟运行 (Build environment Run method)

8. See if the Minion side is performing successfully

[[email protected] init]# Salt ' * ' state.highstate

[[email protected] init]# Salt ' * ' cmd.run ' cat/etc/resolv.conf '
