解決辦法:

1》yum install mysql --nogpgcheck   /* --nogpgcheck     disable gpg signature checking*/

2》[root@localhost yum.repos.d]# rpm --import /ISO鏡像完整路徑/rpm-gpg/RPM-GPG-KEY-redhat-release

error: /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release: import read failed(-1).


3》[root@localhost rpm-gpg]# pwd
/etc/pki/rpm-gpg

[root@localhost rpm-gpg]# ll
total 40
-rw-r--r-- 1 root root 1397 Feb 25  2012 RPM-GPG-KEY
-rw-r--r-- 1 root root 1744 Feb 25  2012 RPM-GPG-KEY-EL4
-rw-r--r-- 1 root root 1519 Feb 25  2012 RPM-GPG-KEY-fedora
-rw-r--r-- 1 root root 1076 Feb 25  2012 RPM-GPG-KEY-fedora-test
-rw-r--r-- 1 root root 1397 Feb 25  2012 RPM-GPG-KEY-oracle

rpm --import /etc/pki/rpm-gpg/RPM* 

4》如果可以連外網可以使用下面的方法

RHEL7:

rpm --import http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7

RHEL6:

rpm --import http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6

RHEL5
rpm --import http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-5

RHEL4
rpm --import http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS4
