Update your local MySQL source with MySQL website configuration

参考连接：51759200前提环境：Centos 6.* 本身配置的yum源自带的mysql版本为5.1；后续希望yum安装5.*其他版本的数据库可以使用新增yum源进行测试安装。

1. Configure the Yum source

Download the Yum source RPM installation package on the MySQL website: http://dev.mysql.com/downloads/repo/yum/

2. # download MySQL Source installation package

        shell> wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm        安装yum源        shell> yum localinstall mysql57-community-release-el7-8.noarch.rpm

3. Check if the MySQL source is installed successfully

  shell> yum repolist enabled | grep "mysql.*-community.*"

4, see the instructions can be MySQL source installation completed.

   可以修改vim /etc/yum.repos.d/mysql-community.repo源，改变默认安装的mysql版本。比如要安装5.6版本，将5.7源的enabled=1改成enabled=0。然后再将5.6源的enabled=0改成enabled=1即可。改完之后的效果如下所示：

Subsequent installation of the database can be done using yum install Mysql-community-server!

Follow-up: Feel this replacement of the original Yum source for the high-level installation of the database is relatively novel, so recorded.
