在做的时候，主控机和受控机已经连接了
首先，先把受控机恢复快照到空配置的时候
此时ssh则需要输入密码
[root@control httpd]# ssh web01.example.com root@web01.example.com's password: Activate the web console with: systemctl enable --now cockpit.socket This system is not registered to Red Hat Insights. See https://cloud.redhat.com/ To register this system, run: insights-client --register Last login: Fri May 27 15:43:57 2022 [root@localhost ~]# exit logout Connection to web01.example.com closed.
设置免密登录
[root@control httpd]# ssh-copy-id web01.example.com
/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@web01.example.com's password:
Number of key(s) added: 1
Now try logging into the machine, with: "ssh 'web01.example.com'"
and check to make sure that only the key(s) you wanted were added.
//现在可以ping通了
[root@control httpd]# ansible all -m ping
web01.example.com | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
"ping": "pong"
}
