ansible常用模块使用详解
1.ansible常用模块之ping
[root@hm1 ~]# ansible all -m ping
192.168.70.138 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
"ping": "pong"
}
2. ansible常用模块之command
[root@hm1 ~]# ansible 192.168.70.138 -m command -a 'mkdir 123'
[WARNING]: Consider using the file module with state=directory rather than
running 'mkdir'. If you need to use command because file is insufficient you
can add 'warn: false' to this command task or set 'command_warnings=False' in
ansible.cfg to get rid of this message.

3. ansible常用模块之raw
//支持重定向
[root@ansible ~]# ansible 172.16.103.129 -m raw -a 'echo "hello world" > /tmp/test'
172.16.103.129 | SUCCESS | rc=0 >>

shell模块亦支持管道与重定向。
//查看受控机上的脚本
[root@localhost ~]# ll /scripts/
