目录是软件包安装源，需要配置，官网有相应教程

/etc/yum.repos.d/

创建MySQL 安装源 mysql-community.repo

内容

# Enable to use MySQL 5.7

[mysql57-community]

name=MySQL 5.7 Community Server

baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/

enabled=1

gpgcheck=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

 

如果报gpgkey错误就把gpgcheck改成0,不校验就好了。

 You could try using --skip-broken to workaround the problem

 You could try running: rpm -Va --nofiles –nodigest

 

经过一下午的努力centos7安装mysql时遇到以上错误，解决安装包之后还是不能正确安装mysql，原来是自己的mysql源里面的6和我们使用的CentOS7不匹配导致mysql安装不成功，只需要把所以的6改成7即可
