CentOS7 yum安装MySql报错The GPG keys listed for the MySQL 8.0 Community Server repository are already installed but they are not correct for this package.的解决方法

在CentOS7中使用yum安装MySql8的时候，遇到这个问题。

原因是，MySQL GPG密钥已过期，无法从官方存储库安装或升级MySQL包。其他详细信息也可以在MySQL网站上找到：https://bugs.mysql.com/bug.php?id=106188

解决方法是，在运行安装程序之前导入密钥：

rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022

对于Ubuntu系统：

wget -q -O - https://repo.mysql.com/RPM-GPG-KEY-mysql-2022 | apt-key add -
