linux服务-anbsible 常用模块
ansible常用模块使用详解
ansible常用模块有:
- ping
- yum
- template
- copy
- user
- group
- service
- raw
- command
- shell
- script
ansible常用模块raw、command、shell的区别:
- shell模块调用的/bin/sh指令执行
- command模块不是调用的shell的指令,所以没有bash的环境变量
- raw很多地方和shell类似,更多的地方建议使用shell和command模块。但是如果是使用老版本python,需要用到raw,又或者是客户端是路由器,因为没有安装python模块,那就需要使用raw模块了
ping模块
[root@ansible ~]# ansible 192.168.248.133 -m ping
192.168.248.133 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
"ping": "pong"
}
command模块
若不指定模块,则默认使用该模块(不支持管道重定向)
[root@ansible ~]# ansible 192.168.248.133 -m command -a 'ls /root'
192.168.248.133 | CHANGED | rc=0 >>
anaconda-ks.cfg
[root@ansible ~]# ansible 192.168.248.133 -m command -a 'echo "123" > /tmp/a'
192.168.248.133 | CHANGED | rc=0 >>
123 > /tmp/a
[root@ansible ~]# ansible 192.168.248.133 -m command -a 'ls /tmp'
192.168.248.133 | CHANGED | rc=0 >>
ansible_command_payload_lovox0nu
row模块
其支持管道符与重定向
[root@ansible ~]# ansible 192.168.248.140 -m raw -a 'echo "123" > /tmp/a'
192.168.248.140 | CHANGED | rc=0 >>

ansible_command_payload_oqlgr2mo
shell模块
shell模块用于在受控机上执行受控机上的脚本,亦可直接在受控机上执行命令。
shell模块亦支持管道与重定向。
root@ansible ~]# ansible 192.168.248.133 -m shell -a '/bin/bash /tmp/test.sh'
