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

1、把这行中的6改为7# baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/

2、把gpgcheck=改为0

# 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/7/$basearch
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql-2023
       file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql-2022
       file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

保存后再执行就能正常安装了。
