更新Centos6.2 yum的163源

   刚装完的Centos6.2的yum源默认是官网的源，使用yum起来比较慢，就想使用163的源，以下是我的步骤，有这方面的需求的可以看下：首先，备份下Centos-base.repo

#mv /etc/yum.repos.d/Centos-Base.repo /etc/yum.repos.d/Centos-Base.repo.bak

#vi /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.

#

#

[base]

name=CentOS-$releasever - Base

#mirrorlist=

baseurl=

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

#released updates

[updates]

name=CentOS-$releasever - Updates

#mirrorlist=

baseurl=

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

#additional packages that may be useful

[extras]

name=CentOS-$releasever - Extras

#mirrorlist=

baseurl=

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

#additional packages that extend functionality of existing packages

[centosplus]

name=CentOS-$releasever - Plus

#mirrorlist=

baseurl=

gpgcheck=1

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

#contrib - packages by Centos Users

[contrib]

name=CentOS-$releasever - Contrib

#mirrorlist=

baseurl=

gpgcheck=1

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

 

完成以上保存退出，使用yum clean all,清空以前的yum 缓存，再yum makecache下，就可以了，如果需要安装其它的源，可手动添加，如增加RPMforge源：

rpm  -ivh
