第一個問題:若是客戶端不在known_hosts文件裏面會出行一些提示shell
執行 # ansible IP地址 -m command -a 'date'服務器
paramiko: The authenticity of host '10.252.129.216' can't be established.oracle
The ssh-rsa key fingerprint is cef5f02a439420eab5472a6384d14ddc.app
Are you sure you want to continue connecting (yes/no)? ssh
我不想輸入yes或者no,取消這個提示,怎麼辦?ide
很簡單,修改ansible.cfg的#host_key_checking= False取消註釋,便可。spa
第二個問題:若是ansible命令登陸須要經過輸入命令的服務器,會出現如下錯誤:ci
[root@reedoracle ansible]# ansible app -m shell -a "ls -l /tmp" -u reedit
rhel56-192.168.209.133 | UNREACHABLE! => {io
"changed": false,
"msg": "No authentication methods available",
"unreachable": true
}
rhel61-192.168.209.142 | UNREACHABLE! => {
"changed": false,
"msg": "No authentication methods available",
"unreachable": true
}
解決辦法:二選一
一、要不修改ansible.cfg配置文件的ask_pass= True給取消註釋,
二、要不就在運行命令時候加上-k,這個意思是-k, --ask-pass ask for SSH password
