前言
SaltStack 是一款高性能的自动化运维工具
类似的工具还有 Puppet、Chef、Ansible，他们之间可以相互替代，但是哪一个更好，我就不在此引发圣战了
这里分享一下 SaltStack 执行命令的方法
Tip: 当前的版本为 Latest release: 2017.7.3 (February 5, 2018)

[root@h209 ~]#一般而言，语法如下
salt <target> <module.function> [argument]- target: 指定哪些系统来执行以下命令
- command (module.function): 命令由模块和方法构成，这是 salt 的处理逻辑
- arguments: 处理逻辑需要的参数，有些没有参数，就不必添加，有些参数具备默认值，也可以不必加，但是可以通过改变参数值来调整处理逻辑
salt 加 执行对象 加 模块.方法 加 参数
查看磁盘用量
[root@h209 ~]# salt "*" disk.usage
