修改Centos 6.4 软件升级默认yum源

Read

Centos进行软件升级的时候，可能会使用Centos官方默认的yum源来进行更新，为了快速更新、下载软件，可以把yum源修改为国内镜像。通过编辑/etc/yum.repos.d/CentOS-Base.repo来达到修改yum源的目的。

方法一、：
脚本演示：

cd /etc/yum.repos.d/
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
mv CentOS6-Base-163.repo CentOS-Base.repo
yum makecache

cd /etc/yum.repos.d/

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

mv CentOS6-Base-163.repo CentOS-Base.repo

yum makecache

操作过程：

[root@Byrd www]# cd /etc/yum.repos.d/
[root@Byrd yum.repos.d]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup    #备份默认yum源
[root@Byrd yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo    #获取163官方yum源
[root@Byrd yum.repos.d]# mv CentOS6-Base-163.repo CentOS-Base.repo    #将163官方获取到的yum源改名为默认yum源
[root@Byrd yum.repos.d]# yum makecache    #服务器包信息下载到本地，以提高本地检索速度

[root@Byrd www]# cd /etc/yum.repos.d/

[root@Byrd yum.repos.d]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup #备份默认yum源

[root@Byrd yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo #获取163官方yum源

[root@Byrd yum.repos.d]# mv CentOS6-Base-163.repo CentOS-Base.repo #将163官方获取到的yum源改名为默认yum源

[root@Byrd yum.repos.d]# yum makecache #服务器包信息下载到本地，以提高本地检索速度

[root@WWW yum.repos.d]# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*    #导入证书

0	[root@WWW yum.repos.d]# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY* #导入证书
