ansible模块--script模块

chdir=/目录 进入到指定目录
creates 文件存在 脚本不执行
removes 文件存在 脚本执行

1.执行script模块

[root@ansible ~]# cat /root/test.sh 
#!/bin/sh
echo `hostname`

[root@ansible ~]# ansible mysql -m script -a '/root/test.sh'
192.168.56.88 | CHANGED => {
    "changed": true, 
    "rc": 0, 
    "stderr": "Shared connection to 192.168.56.88 closed./r/n", 
    "stderr_lines": [
        "Shared connection to 192.168.56.88 closed."
    ], 
    "stdout": "mysql8/r/n", 
    "stdout_lines": [
        "mysql8"
    ]
}

2.可以针对某个文件存在或者不存在来执行脚本,

/etc/passwd文件存在，所以后面的语句被跳过​

[root@ansible ~]# ansible mysql -m script -a 'creates=/etc/passwd chdir=/root test.sh'
192.168.56.88 | SKIPPED

/etc/passwd文件存在，所以后面的语句被执行

[root@ansible ~]# ansible mysql -m script -a 'removes=/etc/passwd chdir=/root test.sh'
192.168.56.88 | CHANGED => {
    "changed": true, 
    "rc": 0, 
    "stderr": "Shared connection to 192.168.56.88 closed./r/n", 
    "stderr_lines": [
        "Shared connection to 192.168.56.88 closed."
    ], 
    "stdout": "mysql8/r/n", 
    "stdout_lines": [
        "mysql8"
    ]
}
