1.roles/mariadb/tasks/main.yml

# mariadb安装后，默认不需要密码，在此也不设置
# 安装数据库
yum -y install mariadb mariadb-server

# 启动数据库并加入开机自启动
systemctl start mariadb
systemctl enable mariadb

# mariadb数据库内创建zrlog、zh库，并授权用户和主机
create database zrlog;
create database zh;

grant all on zrlog.* to zrlog@'%' identified by '123456';
grant all on zh.* to zh@'%' identified by '123456';


flush privileges;

# 上传zrlog、zh 数据库文件至/tmp目录（过程略）
# 导入zrlog、zh 数据库文件至mariadb数据库中
mysql < zrlog.sql
mysql < zh.sql
