                        become)
結尾參數-k 意思是要讓輸入ssh 密碼

例：檢查某節點的httpd 服務
[root@master ~]# ansible slave -m service -a "name=httpd state=running" –s

[root@master tmp]# ansible client02 -m service -a "name=httpd state=running" -s
client02 | SUCCESS => {
    "changed": false, 
    "name": "httpd", 
    "state": "started"
}

[root@master tmp]# ansible slave -m service -a "name=httpd state=stopped" -k
SSH password: 111111
client01 | SUCCESS => {
    "changed": false, 
    "name": "httpd", 
    "state": "stopped"
}
client02 | SUCCESS => {
    "changed": false, 
    "name": "httpd", 
    "state": "stopped"
}

[root@master tmp]# ansible client02 -m service -a "name=httpd state=status" -s
client02 | FAILED! => {
    "changed": false, 
    "failed": true, 
    "msg": "value of state must be one of: running,started,stopped,restarted,reloaded, got: status"
