第一个问题:如果客户端不在known_hosts文件里面会出行一些提示
执行 # ansible IP地址 -m command -a 'date'
paramiko: The authenticity of host '10.252.129.216' can't be established.
The ssh-rsa key fingerprint is cef5f02a439420eab5472a6384d14ddc.
Are you sure you want to continue connecting (yes/no)?
我不想输入yes或者no,取消这个提示,怎么办?
很简单,修改ansible.cfg的#host_key_checking= False取消注释,即可。
第二个问题:如果ansible命令登录需要通过输入命令的服务器,会出现以下错误:
[root@reedoracle ansible]# ansible app -m shell -a "ls -l /tmp" -u reed
rhel56-192.168.209.133 | UNREACHABLE! => {
"changed": false,
"msg": "No authentication methods available",
"unreachable": true
}
rhel61-192.168.209.142 | UNREACHABLE! => {
"changed": false,
"msg": "No authentication methods available",
"unreachable": true
}
解决办法:二选一
1、要不修改ansible.cfg配置文件的ask_pass= True给取消注释,
2、要不就在运行命令时候加上-k,这个意思是-k, --ask-pass ask for SSH password
