CentOS7 安装官网最新MariaDB

在/etc/yum.repos.d/创建MariaDB.repo
方法一
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.2/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

方法二，官网的方法
curl -LsS https://downloads.mariadb.com/MariaDB/mariadb_repo_setup | sudo bash
yum install -y mariadb-server
比较慢，需要挂代理。

初始化命令 mysql_secure_installation

使用国内服务器比较快：
