top file文件的作用：
告诉minion端在哪台机器上执行什么操作：
例子：
# cat /srv/salt/top.sls
base: =============>指明什么环境
'*.example.com': =============>指明哪台机器
- apache =============>指明需要执行什么状态
apache.sls文件：
apache-install: ==============>id,可随意取
pkg.installed: ==============>模块和方法
- names: ==============>指定下面需要安装什么模块
- httpd ==============>需要哪个软件包
- httpd-devel ==============>需要哪个软件包
apache-service: ==============>id,可随意取
service.running: ==============>模块和方法
- name: httpd ==============>程序名
- enable: True ==============>是否开机自启动
- reload: True ==============>是否允许重载
# salt '*' state.sls apache
salt 命令
* 指明哪一台机器
state 模块
sls 方法
apache 指明是哪个状态文件需要执行
