Ansible-使用playbook自动化部署mariadb

1，编写mariadb.yaml文件

[root@c7-4-mh02 ansible]# vim mariadb.yaml
---
    - hosts: mariadb
      remote_user: root
      tasks:
        - name: install mariadb
          yum: name=mariadb-server state=present
        - name: start mariadb
          service: name=mariadb state=restarted enabled=true

2，检查mariadb.yaml文件语法是否正确

# 检查语法是否正确
ansible-playbook --syntax-check mariadb.yaml

# 执行mariadb.yaml文件，安装并启动mariadb
ansible-playbook mariadb.yaml

# 查看mariadb是否启动
systemctl status mariadb
