提示这个咋办？别急

红帽安装rpm安装MySQL时爆出警告： 警告：MySQL-server-5.5.46-1.linux2.6.x86_64.rpm: 头V3 DSA/SHA1 Signature, 密钥 ID 5072e1f5: NOKEY 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

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

[root@node1 apps]# rpm -ivh mysql-community-* --force --nodeps
