Centos7 安装mairadb
1.yum -y install mysql
默认安装的是mariadb，之后用命令：mysql,总是出现：
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
2.之后再运行：
[root@localhost ~]# yum -y install mariadb* 已加载插件：fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.opencas.cn * extras: mirrors.yun-idc.com * updates: mirrors.opencas.cn 软件包

PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on...

By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] y ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] y ... Success!
