命令模块：
每次重启10个主机
$ ansible atlanta -a "/sbin/reboot" -f 10

shell模块：
$ ansible raleigh -m shell -a ‘echo $TERM‘

文件模块：
拷贝文件
$ ansible atlanta -m copy -a "src=/etc/hosts dest=/tmp/hosts"
更改文件属性
$ ansible webservers -m file -a "dest=/srv/foo/a.txt mode=600"
$ ansible webservers -m file -a "dest=/srv/foo/b.txt mode=600 owner=mdehaan group=mdehaan"
创建文件夹
$ ansible webservers -m file -a "dest=/path/to/c mode=755 owner=mdehaan group=mdehaan state=directory"
递归删除
$ ansible webservers -m file -a "dest=/path/to/c state=absent"

包模块：

   Ansible 提供对 yum 和 apt 的支持.这里是关于 yum 的示例.
  确认一个软件包已经安装,但不去升级它:
  $ ansible webservers -m yum -a "name=acme state=present"
  确认一个软件包的安装版本:
  $ ansible webservers -m yum -a "name=acme-1.5 state=present"
  确认一个软件包还没有安装:
  $ ansible webservers -m yum -a "name=acme state=absent"
