MariaDB简介
- MariaDB数据库管理系统是MysqL的一个分支,主要由开源社区在维护,采用GPL授权许可 MariaDB的目的是完全兼容MysqL,包括API和命令行,使之能轻松成为MysqL的代替品。在存储引擎方面,使用XtraDB(英语:XtraDB)来代替MysqL的InnoDB。 MariaDB由MysqL的创始人Michael Widenius(英语:Michael Widenius)主导开发,他早前曾以10亿美元的价格,将自己创建的公司MysqL AB卖给了SUN,此后,随着SUN被甲骨文收购,MysqL的所有权也落入Oracle的手中。MariaDB名称来自Michael Widenius的女儿Maria的名字。

安装PHPMyAdmin
前提安装web服务器和PHP,参考下面:
http://www.jb51.cc/article/p-pukuckix-qq.html
http://www.jb51.cc/article/p-whodiwpn-qq.html
- 安装PHPMyAdmin
# install from EPEL
[root@linuxprobe~]# yum --enablerepo=epel -y install PHPMyAdmin PHP-MysqL PHP-mcrypt
[root@linuxprobe~]# vi /etc/httpd/conf.d/PHPMyAdmin.conf
# line 17: IP address you permit to access
Require ip 127.0.0.1 10.1.1.0/24
# line 34: IP address you permit to access
Require ip 127.0.0.1 10.1.1.o/24
[root@linuxprobe ~]# systemctl restart httpd
使用Web浏览器从客户端访问“http://(您的主机名或IP地址)/ PHPmyadmin /’,然后在MariaDB的用户在以下屏幕上登录。此示例使用root用户继续。
登录之后,您可以在这里操作MariaDB

MariaDB 主从复制和MysqL主从复制相同,请移步到:http://www.jb51.cc/article/p-dobsemhr-qq.html
安装 MariaDB 10.1
- 配置 CentOS SCLo源仓库
[root@linuxprobe ~]# yum --enablerepo=centos-sclo-rh -y install rh-mariadb101-mariadb-server
- 来自centos-sclo-rh的软件包安装在/ opt目录下。 要使用它,加载环境变量如下。
[root@linuxprobe ~]# scl enable rh-mariadb101 bash
[root@linuxprobe ~]# MysqL -V
MysqL Ver 15.1 Distrib 10.1.14-MariaDB,for Linux (x86_64) using EditLine wrapper
[root@linuxprobe ~]# which MysqL
/opt/rh/rh-mariadb101/root/usr/bin/MysqL
[root@linuxprobe ~]# vi /etc/profile.d/rh-mariadb101.sh
# create new
#!/bin/bash
source /opt/rh/rh-mariadb101/enable
export X_SCLS="`scl enable rh-mariadb101 'echo $X_SCLS'`"
- 启用MariaDB 10.1并配置初始设置
[root@linuxprobe ~]# MysqL_secure_installation
