Error: GPG check FAILED

》》错误日志中其实已经把错误信息描述的很清楚了,说白了就是验证 GPG 失败:

文件中的 GPG 密钥:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql (0x5072E1F5) 已安装
为“MySQL 8.0 Community Server”存储库列出的 GPG 密钥已经安装,但它们对于此包不正确。
检查是否为此存储库配置了正确的密钥 URL。失败的包是:mysql-community-client-8.0.32-1.el8.x86_64

2. 解决方案

2.1 直接导入新的 GPG key (推荐)

MySQL 的最新 GPG key 放在其官方的仓库地址中: https://repo.mysql.com

从更新日期中可以看到 MySQL 2022 年更换过一次,截止到 2023年3月17日,目前最新的还是 2022 年更新的。如果以后再遇到此类错误可以去官方仓库地址中看一下,有最新的就直接使用最新的。

# 如果出现上面的报错,需要导入最新的 GPG key 
rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022

执行导入成功后,就可以继续执行相应的安装命令:

yum install mysql-community-server

2.2 跳过验证 (不推荐)

yum install mysql-community-server -y --nogpgcheck

参数说明:
-y:安装中的待确认操作不必询问,默认 yes
--nogpgcheck:忽略 gpg 验证。

3. 其他

MySQL 这个还是好发现的,Docker Hub 上有的时候会直接升级镜像(image),都是泪呀。

踩坑记录: 项目中一直使用 Docker Hub 上的 tomcat:8 镜像,该镜像内使用的是 JDK 1.8;但是有次获取最新的时候,项目直接启动不起来,排查半天,结果是镜像内部的 JDK 变成了 11,用了快 2 年的镜像,谁也没想到会升级,哈哈。后续二次封装了基础镜像,然后上传到了私有仓库;官方镜像虽好,可不要贪杯哟,但是最好自己定制一下。
