 Failing package is: mysql-community-client-8.0.43-1.el7.x86_64
 GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql-2022, file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

看到问题了，这是 GPG 密钥验证失败。我们需要解决密钥问题。以下是几种解决方案：

🔑 解决方案一：跳过 GPG 检查（不推荐用于生产）

# 使用 --nogpgcheck 参数跳过 GPG 检查
sudo yum install mysql-community-server mysql-community-client --nogpgcheck

🔑 解决方案二：正确导入 GPG 密钥

# 重新导入 MySQL GPG 密钥
sudo rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022
sudo rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql

# 或者从本地文件导入（如果已下载）
sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-mysql-2022
sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

# 验证密钥是否导入成功
rpm -qa gpg-pubkey* | grep -i mysql

🔑 解决方案三：手动下载并安装 RPM 包

# 清理缓存
sudo yum clean all

# 手动下载所有必要的 RPM 包
wget https://repo.mysql.com/mysql-community-common-8.0.43-1.el7.x86_64.rpm
wget https://repo.mysql.com/mysql-community-libs-8.0.43-1.el7.x86_64.rpm
wget https://repo.mysql.com/mysql-community-client-8.0.43-1.el7.x86_64.rpm
wget https://repo.mysql.com/mysql-community-server-8.0.43-1.el7.x86_64.rpm

# 安装所有包（跳过 GPG 检查）
sudo rpm -ivh mysql-community-*.rpm --nodeps --force

🔑 解决方案四：配置 Yum 跳过 GPG 检查

# 编辑 MySQL 仓库配置
sudo vi /etc/yum.repos.d/mysql-community.repo

# 在每个 [mysql*] 部分添加
gpgcheck=0

或者临时禁用：

# 临时禁用所有仓库的 GPG 检查
sudo yum install mysql-community-server mysql-community-client --nogpgcheck

🎯 推荐执行顺序

我建议按以下步骤操作：

步骤 1：先尝试重新导入密钥

sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-mysql-2022
sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

步骤 2：如果密钥导入失败，使用跳过 GPG 检查的方式

sudo yum install mysql-community-server mysql-community-client --nogpgcheck

步骤 3：如果上述方法都不行，手动下载安装

# 下载所有必要包
wget https://repo.mysql.com/mysql-community-common-8.0.43-1.el7.x86_64.rpm
wget https://repo.mysql.com/mysql-community-libs-8.0.43-1.el7.x86_64.rpm
wget https://repo.mysql.com/mysql-community-client-8.0.43-1.el7.x86_64.rpm
wget https://repo.mysql.com/mysql-community-server-8.0.43-1.el7.x86_64.rpm

# 安装（注意安装顺序）
sudo rpm -ivh mysql-community-common-8.0.43-1.el7.x86_64.rpm
sudo rpm -ivh mysql-community-libs-8.0.43-1.el7.x86_64.rpm
sudo rpm -ivh mysql-community-client-8.0.43-1.el7.x86_64.rpm
sudo rpm -ivh mysql-community-server-8.0.43-1.el7.x86_64.rpm

⚠️ 注意依赖关系

如果手动安装遇到依赖问题，可以：

# 一次性安装所有包，自动解决依赖
sudo yum localinstall mysql-community-*.rpm --nogpgcheck

请先尝试方案二（重新导入密钥），如果不行再用方案一（跳过GPG检查）。 这两种方法应该能解决您的问题。
