使用Ansible Role自动化搭建LNMP环境
1、环境配置
| 主机名 | 配置 | 运行服务 | 备注 |
|---|---|---|---|
| node01 | 2核4G | nginx | |
| node02 | 1核2G | php、mysql |
2、准备工作
- 安装ansible工具
# yum install -y ansible
- 配置主机名，做免密
# vim /etc/hosts
192.168.85.128 node01
192.168.85.129 node02
# ssh-keygen
# ssh-copy-id root@node01
# ssh-copy-id root@node02
- 将使用到的文件放到指定目录（我已经打包上传到百度云，需要的自取）

- 编写playbook
# vim lnmp-role.yaml
- hosts: node01
remote_user: root
roles:
- lnmp-nginx
- hosts: node02
remote_user: root
roles:
- lnmp-php
- lnmp-mysql
三、使用ansible-playbook运行
root@DESKTOP-Q4O3FV5:~/playbooks# ansible-playbook lnmp-role.yaml

运行完毕，没有报错，进行验证

备注：如果用主机名进行访问的话，记得在windows的hosts里面配置解析
