可能给出ssh_exchange_identification错误

Question

我的Ansible剧本使用代理连接到远程节点。

当Ansible攻略运行时，它在执行ssh步骤时会给出以下错误。

[root@vm1-msdp ANSIBLE]# ansible-playbook fend_file.yaml -i env/target -vvvvv

PLAY [LAB1] *******************************************************************

fatal: [10.169.99.222] => SSH Error: ssh_exchange_identification: Connection closed by remote host
It is sometimes useful to re-run the command using -vvvv, which prints SSH debug output to help diagnose the issue.

但是，当我自己运行ssh命令时，我能够成功连接。

[root@vm1-msdp ANSIBLE]# ssh -C -tt -o ProxyCommand="nc -x 142.133.134.161:1088 %h %p" -o StrictHostKeyChecking=no -o GSSAPIAuthentication=no -o PubkeyAuthentication=no -o User=root -o ConnectTimeout=10 10.169.99.222

我需要清除任何ansible文件吗？

当您手动运行SSH命令时，您将指定root用户。您的行动手册正在使用您的本地用户msdp。尝试在清单文件中设置ansible_user变量。可能是这样的：

10.169.99.22 ansible_user=root
