这里发现这个问题：
Public key for mysql-community-server-5.7.37-1.el7.x86_64.rpm is not installed Failing package is: mysql-community-server-5.7.37-1.el7.x86_64 GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
备注：
由于MySQL在CentOS7中收费了，所以已经不支持MySQL了，取而代之在CentOS7内部集成了mariadb，而安装MySQL的话会和MariaDB的文件冲突。
如果安装的话，需要卸载MariaDB，另外也注意安装正确的安装包，以及安装顺序，建议参考我的另外一篇文章。
