Mariadb安装

1、创建MariaDB.repo

vi /etc/yum.repos.d/Mariadb.repo

2、将以下文件中的字段添加到MariaDB.repo文件中

# MariaDB 10.3 CentOS repository list - created 2016-12-01 03:36 UTC
# 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

  国内配置可采用如下配置：

# MariaDB 10.3 CentOS repository list - created 2017-07-03 06:59 UTC

gpgcheck=1

3、yum安装MariaDB

     yum -y install MariaDB-server MariaDB-client

4、启动MariaDB服务

     systemctl start mysql.service

5、卸载

     yum -y remove mari*

     rm -rf /var/lib/mysql/*
