ansible常用模块之shell

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。

//在受控主机上简单创建一个脚本
[root@localhost ~]# mkdir /scripts
[root@localhost ~]# cd /scripts/
[root@localhost scripts]# ls
[root@localhost scripts]# vim test.sh 
#!/bin/bash

for i in $(seq 10);do
        echo $i
done

//使用shell模块在受控机上执行受控机上的脚本
[root@ansible ~]# ansible 192.168.118.130 -m shell -a '/bin/bash /scripts/test.sh'
