解释 GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

GPG Keys are used for secure communication and authentication in software package management systems. In the context of the MySQL database management system, GPG keys are configured as a file location within the system, specifically at file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql. This indicates that the GPG key for MySQL is stored locally on the system in the specified file location. The purpose of this configuration is to ensure that any software packages related to MySQL are securely authenticated and verified before they are installed on the system.

Failing package is: mysql-community-common-5.7.42-1.el7.x86_64 GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

这个错误提示是因为在安装 `mysql-community-common-5.7.42-1.el7.x86_64` 时，系统检测到该软件包的 GPG 签名无效或未找到相应的 GPG 密钥。

如果您确定该软件包是可信的，并且您已经从官方网站下载了 GPG 密钥，则可以尝试导入该密钥来解决此问题。您可以使用以下命令导入 MySQL 官方 GPG 密钥：

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

如果您已经导入了 GPG 密钥但仍然遇到此问题，则可以尝试清除 Yum 缓存并再次运行安装命令：

yum clean all
yum install mysql-community-common-5.7.42-1.el7.x86_64

如果问题仍然存在，请尝试在安装命令中添加 `--nogpgcheck` 参数来禁用 GPG 检查：

yum install mysql-community-common-5.7.42-1.el7.x86_64 --nogpgcheck

请注意，禁用 GPG 检查可能会降低系统的安全性，因此请仅在您清楚了解风险并且确定软件包来源可信时使用该选项。
