[root@wang yum]# ssh-copy-id root@192.168.170.137 #设置免密登入
[root@wang yum]# cat /etc/hosts #配置清单文件
192.168.170.134 apache
192.168.170.137 cos7
将ansible配置文件f复制到yum目录下
[root@wang yum]# cp /etc/lamp/inventory
[root@wang yum]# cp /etc/ansible/ansible.cfg .
尝试能否ping通
[root@wang yum]# ansible cos7 -m ping
cos7 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
查看清单
[root@wang yum]# ansible all --list-hosts
hosts (2):
apache
cos7
