centos7安装mysql报错问题

如果采用命令

yum install mysql-server mysql-libs mysql

来安装mysql，报如下错误

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirrors.skyshe.cn
 * extras: mirrors.zju.edu.cn
 * updates: centos.ustc.edu.cn
No package mysql-server available.
Package 1:mariadb-libs-5.5.47-1.el7_2.x86_64 already installed and latest version
Package 1:mariadb-5.5.47-1.el7_2.x86_64 already installed and latest version
Nothing to do

其中，出现

No package mysql-server available.

之类的错误的话，是因为CentOs7采用MariaDB来代替Mysql，可以使用

yum -y install mariadb-server mariadb

来安装。如果要按照原来方法安装MySQL的话，添加如下语句

sudo rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

这样就可以按照原来方法安装MySQL了。
