安装MySQL报错

Public key for mysql-community-common-5.7.41-1.el7.x86_64.rpm is not installed

解决方法：

重新导入秘钥

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

然后再执行 安装命令即可

yum -y install mysql-community-server

问题2：

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-5.7.39-1.el7.x86_64
GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

网上的解决方案，同上

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