 You could try using --skip-broken to work around the problem

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

修改vim /etc/yum.repos.d/mysql-community.repo 源文件

vim  /etc/yum.repos.d/mysql-community.repo

修改如下文件

[mysql57-community-dmr]

name=MySQL 5.7 Community Server Development Milestone Release

baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/     # IDO老徐 注： el/6 -> el/7

enabled=1

gpgcheck=0   # IDO老徐注： 1 > 0

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

搞定；

再次执行

yum install mysql-community-server  #再次安装mysql

搞定 ；
