saltstack 实现系统初始化

1、整体结构如下

[root@zabbix init]# pwd

/srv/salt/base/init

[root@zabbix init]# ll

total

-rw-r--r--  root root  Jun  : audit.sls

-rw-r--r--  root root  Mar    dns.sls

-rw-r--r--  root root   Jun  : env_init.sls

drwxr-xr-x  root root   Jun  : files

-rw-r--r--  root root   Jun  : history.sls

-rw-r--r--  root root  Jun  : sysctl.sls

2、状态文件内容如下

[root@zabbix 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"; }'

[root@zabbix init]# cat dns.sls

/etc/resolv.conf:

  file.managed:

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

    - user: root

    - gourp: root

    - mode: [root@zabbix init]# cat history.sls

/etc/profile:

  file.append:

    - text:

      - export HISTTIMEFORMAT="%F %T `whoami`"

[root@zabbix init]# cat sysctl.sls

net.ipv4.ip_local_port_range:

  sysctl.present:

    - value:

fs.file-max:

  sysctl.present:

    - value:

net.ipv4.ip_forward:

  sysctl.present:

    - value:

vm.swappiness:

  sysctl.present:

    - value:

[root@zabbix init]# cat env_init.sls

include:

  - init.dns

  - init.history

  - init.audit

  - init.sysctl

[root@zabbix init]# cat /srv/salt/base/top.sls

base:

  '*':

    - init.env_init

3、执行结果

[root@zabbix init]# salt '*' state.highstate test=True #可以先测试一下

[root@zabbix init]# salt '*' state.highstate test=True
