关于Public key for *.rpm is not installed 的解决方法

今天在安装mysql提示错误

Public key for mysql-server-5.0.45-7.el5.i386.rpm is not installed

解决方法：此时要导入rpm的签名信息即可以root登录，执行下面命令

# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

Linux版本是CentOS 5.4执行下面命令

#rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
