mariadb

MariaDB数据库管理系统是MySQL的一个分支，主要由开源社区在维护，采用GPL授权许可 MariaDB的目的是完全兼容MySQL，包括API和命令行，使之能轻松成为MySQL的代替品。在存储引擎方面，使用XtraDB来代替MySQL的InnoDB。 MariaDB由MySQL的创始人Michael Widenius主导开发，他早前曾以10亿美元的价格，将自己创建的公司MySQL AB卖给了SUN，此后，随着SUN被甲骨文收购，MySQL的所有权也落入Oracle的手中。MariaDB名称来自Michael Widenius的女儿Maria的名字。

最终实现在线下载mariadb二进制包，安装依赖，环境变量设置，初始化数据库，创建库，创建用户，创建用户权限，远程连接设置，版本获取，安装完成删除包，防火墙设置。
/usr/local/mysql 安装位置
/usr/local/mysql/data 数据目录
linux 系统创建的mariadb 是mysql
root/Report@123 mariadb数据库登录管理员
mar/Report@123 此账号是自定义创建的管理员，生产环境删除哦
mariadb_test 创建的临时数据库
/usr/local/mysql/support-files/systemd/mariadb.service #默认官方的服务脚本
