问题分析

我们定位到错误地方

The GPG keys listed for the "MySQL 5.7 Community Server" repository are already installed but they are not correct for this package. Check that the correct key URLs are configured for this repository. Failing package is: mysql-community-client-5.7.38-1.el7.x86_64
 GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

直译过来：

为“MySQL 5.7 社区服务器”存储库列出的 GPG 密钥已安装，但它们对于此软件包不正确。检查是否为此存储库配置了正确的密钥 URL。

可以理解为：CentOS7.6 安装mysql5.7的时候报错，提示某一个包安装不成功。

操作系统：CentOS 7.5
Mysql版本：mysql5.7

总结失败原因：
GPG对于包的源key的验证没有通过

解决办法

在yum install 版本后面加上 --nogpgcheck，即可绕过GPG验证成功安装。比如命令：yum install mysql-community-server --nogpgcheck

[root@qbi-executor-01 mysql]# yum install mysql-community-server --nogpgcheck

看到上面的complet完成就神奇的成功了！

疑问

但是不明白包的源key为什么没有通过验证？这里很奇怪，我尝试了好几个5.7的版本都失败了，之前安装都是成功的，有明白相关信息的欢迎评论分享。
