SaltStack 配置SLS过程

file.managed模块的使用示例：

1.在/etc/salt/master中编辑

file_roots:
  base:
    - /srv/salt
  dev:
    - /srv/salt/dev
  test:
    - /srv/salt/test
  prod:
    - /srv/salt/prod

2.在/srv/salt下面新建目录mkdir dev test prod init

3.在init目录下新建需要管理的文件dns.sls

/etc/resolv.conf:
  file.managed:
    - source: salt://init/files/resolv.conf
    - user: root
    - group: root
    - mode: 644

4.在init目录下新建files目录，拷贝/etc/resolv.conf到/srv/salt/init/files下面，并且修改resolv.conf文件为

nameserver 144.144.144.144
nameserver 8.8.8.8

5.在/srv/salt下面新建top.sls文件,并且重启master服务/etc/init.d/salt-master restart

base:
  '*':
    - init.dns

6.执行salt '*' state.highstate
