CentOS7上YUM安装MariaDB 10

首先先要去mariadb网站获取下载信息，以便下一步编辑安装的配置文件：

找到你要装的版本 - 比如当前选择的是CentOS/64位/10.2
https://downloads.mariadb.org/mariadb/repositories/#mirror=tuna&distro=CentOS&distro_release=centos7-amd64--centos7&version=10.2

配置YUM安装源

下面是 CentOS的自定义安装YUM源，粘贴复制这些到/etc/yum.repos.d/,建议命名
MariaDB.repo

name = MariaDB
baseurl = http://yum.mariadb.org/10.2/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

因为官网的源下载安装非常慢，可以用以下源：
