注意三台都需要联网  
我的是80.100、80.101、80.102  
我是在80.100上操作的其他两台只要开着就行了不需要操作

yum install -y epel-release  //安装epel源
    yum install ansible -y
    
    ansible --version          //查看ansible版本
    
    yum install tree -y
    
    cd /etc/ansible
    vi hosts       //配置主机清单
    最后一行添加
    [web]
    192.168.80.10[1:2]
    
    ansible all --list-hosts    显示所有已定义的主机
    
    ssh-keygen -t rsa
    ssh-copy-id root@192.168.80.101
    ssh-copy-id root@192.168.80.102
    
    ansible all -a 'systemctl stop firewalld'
    
    ansible all -a 'setenforce 0'
