前言
自从 CentOS 7 开始，自带的数据库就变成 MariaDB 了，yum 安装之后的默认版本是 5.5，但是这个数据版本已经比较老了，无论是安装全新的 Percona 还是升级 MariaDB 第一步始终是不要忘记备份。

备份数据库
重要的事情说三遍，备份，备份，备份
# 备份数据库，如果升级顺利是不要实施备份还原的
mysqldump -u root -p --all-databases > alldb.sql
# 如果想保留自己的 my.cof 配置，则备份一下这个文件
cp /etc/my.cnf /etc/my.cnf.bak
# 停止数据库运行
systemctl stop mariadb
# 卸载 MariaDB 老版本
yum remove mariadb mariadb-server
添加 MariaDB Yum 库
建议使用 MariaDB 官方推荐的 stable 稳定版，
https://downloads.mariadb.org/mariadb/ http://yum.mariadb.org/
# 添加 MariaDB 官方源
vi /etc/yum.repos.d/MariaDB.repo
# MariaDB 10.3 CentOS repository list
