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。
总结
到这里，我们也就讲完了《centos7安装mysql5.7的踩坑记录》的内容了。个人认为，基础知识的学习和巩固，是为了更好的将其运用到项目中，欢迎关注golang学习网公众号，带你了解更多关于mysql的知识点！
