ansible之role-创新互联
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'
