什么是mariadb?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。开发这个分支的原因之一是：甲骨文公司收购了MySQL后，有将My
配置第一个实例：
#拷贝配置文件
[root@mariadb 3306]# cp ~/tools/mariadb-5.5.25/support-files/my-small.cnf ./my.cnf
#修改配置文件
[root@mariadb 3306]# cat my.cnf

1、创建/data目录
mkdir /data
chmod 777 /data(要给这个目录至少要附加读写权限)
2、把mariadb服务停掉：
systemctl stop mariadb.service
3、把/var/lib/mysql整个目录复制到/data
cp -r /var/lib/mysql/* /data/
这样就把MySQL的数据文档复制到了/data下
4、编辑mariadb的配置文档/etc/my.cnf
在[client]下添加：
把原来的socket=/var/lib/mysql/mysql.sock，前边加#注释掉，添加socket=/data/mysql.sock（以防有问题再改回来）。
在[mysqld]下添加：
把原来的socket=/var/lib/mysql/mysql.sock，前边加#注释掉，添加socket=/data/mysql.sock（以防有问题再改回来）。
datadir =/datal (这行没有，需要自己加上)
保存后退出。
5、 chown -R mysql:mysql /data/mysql
6、重新启动mariadb服务
systemctl start mariadb.service。

多用户可以访问同一个数据库的。
