centos7 环境下

安装

yum install ansible

配置远程受控机的信息

/etc/ansible/host文件中配置

[server-test]
192.168.11.11 ansible_user=user01

生成ssh-key并推送到配置的用户

ssh-keygena -t ras
ssh-copy-id -i ~/.ssh/id_rsa.pub user01@192.168.11.11

测试连通

ansible server-tset -m  command -a "ls -a /home"

使用角色

可以手动建文件夹操作，也可以用ansible-galaxy init <rolename> 来创建。
可以用ansible-galaxy search <rolename> 来搜索现有的role，然后用ansible-galaxy install <rolename> 来安装使用
