centos7解决yum install mysql-server没有可用包?

第一步:安装从网上下载文件的wget命令

[ ~]# yum -y install wget

第二步:下载mysql的repo源

[ ~]# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

第三步:安装mysql-community-release-el7-5.noarch.rpm包

[ ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm

第四步:查看下

[ ~]# ls -1 /etc/yum.repos.d/mysql-community*
/etc/yum.repos.d/mysql-community.repo
/etc/yum.repos.d/mysql-community-source.repo

会获得两个mysql的yum repo源:/etc/yum.repos.d/mysql-community.repo,/etc/yum.repos.d/mysql-community-source.repo。

第五步:安装mysql

[ ~]# yum install mysql-server
