首先需要添加 yum 的源，通过一个官方脚本可以执行

curl -sS https://downloads.mariadb.com/MariaDB/mariadb_repo_setup | sudo bash

然后执行安装，会安装最新版本数据库

yum install MariaDB-server

安装完之后，查看运行状态

systemctl status mysql

启动数据库

systemctl start mysql

设置开机启动

systemctl enable mysql

进入mysql数据库控制台

mysql

创建数据库和对应的用户/密码

-- 创建数据库
create database homework default character set utf8mb4 collate utf8mb4_unicode_ci;

-- 创建用户
create user homework identified by 'xxxx';

-- 分配权限
grant all privileges on homework.* to 'homework'@'localhost' identified by 'xxxx' with grant option;
grant all privileges on homework.* to 'homework'@'%' identified by 'xxxx' with grant option;
flush privileges ;
