- hosts: all
  tasks: 
    - name: install httpd  # 安装httpd
      yum: name=httpd state=latest
    - name: httpd start and enable # 启动，设置自启
      service: name=httpd state=started enabled=yes
    
    - name: install mariadb  # 安装mariadb
      yum: name={{item}} state=latest
      with_items:
        - mariadb
        - mariadb-server
    - name: mariadb start and enable
      service: name=mariadb state=started enabled=yes

    - name: install php   # 安装php
      yum: name={{item}} state=latest
      with_items:
        - php
        - php-devel
        - php-mysql
      notify:      # 当安装完php,通知handler执行httpd重启
        - httpd restart
  handlers:
    - name: httpd restart
      service: name=httpd state=restarted

然后我们可以使用

1

ansible-playbook xxx.yml --syntax-check

来检查yml是否有语法错误

使用

1

ansible-playbook -i /etc/ansible/hosts ./LAMP.yml

执行剧本

这里，做的时候，另外两台机器之前装过mariadb和httpd，所以这里显示change是0

确定每台机器都正常运行。

LNMP

playbook编写，我们可以直接从刚才的playbook上改动一点就行
