warning: mysql-community-server-5.7.19-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1

CentOS安装rpm安装MySQL时爆出警告：

warning: mysql-community-server-5.7.19-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

 

缘由：这是因为yum安装了旧版本的GPG keys形成的

解决办法：后面加上

--force --nodeps

如：rpm -ivh mysql-community-server-5.7.19-1.el6.x86_64.rpm --force --nodeps
