linux中利用yum 安装 MariaDB 数据库步骤
准备yum一个lamp环境，发现yum版本的mysql居然依然是5.1.x的版本，因此准备更换为MariaDB。
配置源：
[root@localhost ~]# cat /etc/yum.repos.d/MariaDB.repo
# MariaDB 10.0 CentOS repository list - created 2013-08-23 13:08 UTC
# http://mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
检查源：
[root@localhost ~]# yum search mariadb

安装database：
[root@localhost ~]# yum install MariaDB-server MariaDB-client
[root@localhost ~]# yum install MariaDB-*
运行database：
[root@localhost ~]# /etc/init.d/mysql start
Starting MySQL. SUCCESS!
