#测试是否互信成功
[ansible@node1 .ssh]$ ssh 192.168.253.129
[ansible@node2 ~]$ mkdir .ssh
[ansible@node2 ~]$ mv authorized_keys .ssh/
[ansible@node2 ~]$ chmod -R 700 .ssh/

——使用ansible
1）使用ping模块测试是否成功
[ansible@node1 ~]$ chmod g-wx,o-wx .python-eggs/
[ansible@node1 ~]$ ansible all -m ping
192.168.253.131 | success >> {
"changed": false,
"ping": "pong"
}
192.168.253.129 | success >> {
"changed": false,
"ping": "pong"
}
192.168.253.130 | success >> {
"changed": false,
"ping": "pong"
}
127.0.0.1 | success >> {
"changed": false,
"ping": "pong"
}
