安装mysql
1. 添加Mysql5.7仓库
CentOS 7的默认yum仓库中并没有MySQL5.7，我们需要手动添加，好在MySQL官方提供了仓库的地址，所以我们能够比较简单地安装MySQL。
rpm -ivh https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
2. 确认Mysql仓库成功添加
yum repolist all | grep mysql | grep enabled
[root@iZ2zeizsw2xjgxwhbbsxchZ ~]# yum repolist all | grep mysql | grep enabled
mysql-connectors-community/x86_64 MySQL Connectors Community enabled: 108
mysql-tools-community/x86_64 MySQL Tools Community enabled: 90
mysql57-community/x86_64 MySQL 5.7 Community Server enabled: 347
[root@iZ2zeizsw2xjgxwhbbsxchZ ~]#
3. 安装Mysql5.7
yum -y install mysql-community-server
[root@iZ2zeizsw2xjgxwhbbsxchZ ~]# yum -y install mysql-community-server
