Centos 6.0 yum–中国科技大学源 和关于 error: /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6: key 1 import failed.

1.先把/etc/yum.repos.d备份

#cp -a /etc/yum.repos.d/ /etc/yum.repos.d.back

 

2.修改/etc/yum.repos.d/CentOS-Base.repo文件

#vim /etc/yum.repos.d/CentOS-Base.repo

# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.

3.更新yum源

#yum makecache

#yum update

 

4.一切OK！

 

有可能 之后的yum 还会出现 id 和key的错误。。

开始yum -y install gcc
　　可是又出错了
　　warning: rpmts_HdrFromFdno: Header V3 RSA/SHA256 Signature, key ID c105b9de: NOKEY
　　updates/gpgkey
　　Public key for glibc-common-2.12-1.7.el6_0.5.x86_64.rpm is not installed
　　gpgchek没过，解决方法有三种：（推荐第三个）
　　1.运行
　　[root@RedHat Packages]# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
　　可能能解决；
　　但是如果导入过了这一条就不起作用了，会提示
　　error: /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release: key 1 import failed.
　　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
