ansible使用

[root@x112 ~]# yum repolist
[root@x112 ~]#ssh-keygen 
[root@x112 ~]#ssh-copy-id 192.168.0.160
[root@x112 ~]#ssh 192.168.0.160

[root@x112 ~]# yum -y install ansible　　　　　　#需要epel扩展源
[root@x112 ~]# cat /etc/ansible/ansible.cfg

添加模块信息，例如如下：
[root@x112 ~]#  vim /etc/ansible/hosts 
[webserver]
192.168.0.160

[root@x112 ~]# ansible  webserver -m shell -a 'systemctl stop firewalld'
[root@web1 ~]# systemctl status firewalld.service 
firewalld.service - firewalld - dynamic firewall daemon
