（一）ansible基本格式
HOST-PATTERN #匹配主机模式,如all表示所有主机
-a MOD_ARGS #模块执行的参数
-f FORKS #生成几个子进行程执行
-C #(不执行，模拟跑)
-u Username #某主机的用户名
-c CONNection #连接方式（default smart）
完整示例:
[root@ansible ansible]# ansible all -m shell -a "ip add"
[root@ansible ansible]# ansible all -m shell -a "mkdir /root/sanchuang"
[root@ansible ansible]# ansible all -m shell -a "ls /root"
[root@ansible ansible]# ansible webservers -m shell -a "ip add"
（二）ansible-doc 获取帮助信息
ansible模块比较多,可以通过ansible-doc --help 显示帮助信息
ansible-doc -l 获取所有当前版本下的可用模块及简要信息
ansible-doc -s 模块名 获取指定模块帮助信息说明
#查看copy模块的使用说明
[root@ansible lianxi]# ansible-doc copy
[root@ansible ansible]# ansible-doc -l
