1、报错信息如下:
warning: /var/cache/yum/x86_64/7/mysql57-community/packages/mysql-community-server-5.7.37-1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3a79bd29: NOKEY
Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
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-server-5.7.37-1.el7.x86_64
GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

2、原因:
由于MySQL GPG 密钥已过期导致的
3、解决方法:
以2022年为例
运行命令:
rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022
这篇博客主要介绍了在遇到MySQL 5.7社区服务器的安装过程中,由于GPG密钥过期导致的报错问题。报错信息表明RPM包的签名无法验证,因为密钥不匹配。解决这个问题的方法是在2022年通过运行特定的命令来导入新的GPG密钥,即`rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022`。
