通过ansible命令直接ping多台机器的网络状态,提示报错
172.16.24.220 | UNREACHABLE! => {
"changed": false,
"msg": "Failed to connect to the host via ssh: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).\r\n",
"unreachable": true
}
解决方式:单向的ssh验证
ssh-keygen一路回车,主要是用来免密通信的
ssh-copy-id 172.16.24.220 需要输入对应主节的root密码
[root@chm log]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
7f:69:87:cf:28:fe:8b:19:55:a7:d0:c9:aa:6d:05:0c root@chm
The key's randomart image is:
+--[ RSA 2048]----+
| E |
| o o . |
| + = .|
| = o |
| S o o |
| . + + |
| + B . |

[root@chm log]#
[root@chm log]# ssh-copy-id 172.16.24.220
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@172.16.24.220's password:
Number of key(s) added: 1
Now try logging into the machine, with: "ssh '172.16.24.220'"
and check to make sure that only the key(s) you wanted were added.
再次验证,成功
[root@chm log]# ansible 172.16.24.220 -m ping
172.16.24.220 | SUCCESS => {
"changed": false,
"failed": false,
"ping": "pong"
}
记录一下,希望可以帮到更多人
