Linux解压Mysql报错：警告：mysql-community-libs-5.7.28-1.el7.x86_64.rpm: 头V3 DSA/SHA1 Signature, 密钥 ID 5072e1

在安装目录下执行rpm安装时报错：

[root@hadoop102 software]# rpm -ivh mysql-community-libs-5.7.28-1.el7.x86_64.rpm

[root@hadoop102 software]# yum install mysql-community-common(x86-64)

原因：这是由于yum安装了旧版本的GPG keys造成的 解决办法：后面加上

 --force --nodeps

如： 

 rpm -ivh MySQL-server-5.5.46-1.linux2.6.x86_64.rpm --force --nodeps

从 RPM 版本 4.1 开始，在安装或升级软件包时会检查软件包的签名。

用此命令对RPM包再次进行安装：

[root@hadoop102 software]# rpm -ivh mysql-community-libs-5.7.28-1.el7.x86_64.rpm --force --nodeps
