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
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.3/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

# 清除 yum 缓存 
yum clean all 
yum makecache

升级已有数据库

# 安装 MariaDB 新版本 
yum install mariadb mariadb-server

# 启动新版 MariaDB
systemctl start mariadb

# 升级已有数据库
