两种方法可以解决：

1.运行

[root@RedHat Packages]# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

可解决；

2.运行

[root@RedHat Packages]# yum.conf 文件,把里面的gpgcheck=1改为gpgcheck=0

(不推荐)。

注：方法2的效果很好

3.最好的解决办法：

加上"--nogpgcheck"参数

[root@RedHat Packages]# yum install google-chrome-stable_current_i386.rpm --nogpgcheck
