CentOS 5 yum的配置

hi_good

先备份
cp /etc/yum.repos.d/CentOS-Base.repo CentOS-Base.repo.bak
# vi /etc/yum.repos.d/CentOS-Base.repo
用下面的这段话替换掉原来的
[base]
name=CentOS-5.0 - Base
baseurl=http://mirror.be10.com/centos/5.0/os/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
#released updates
[update]
name=CentOS-5.0 - Updates
baseurl=http://mirror.be10.com/centos/5.0/updates/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
#packages used/produced in the build but not released
[addons]
name=CentOS-5.0 - Addons
baseurl=http://mirror.be10.com/centos/5.0/addons/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
#additional packages that may be useful
[extras]
name=CentOS-5.0 - Extras
baseurl=http://mirror.be10.com/centos/5.0/extras/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-5.0 - Plus
baseurl=http://mirror.be10.com/centos/5.0/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
#contrib - packages by Centos Users
[contrib]
name=CentOS-5.0 - Contrib
baseurl=http://mirror.be10.com/centos/5.0/contrib/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
#packages in testing
[testing]
name=CentOS-5.0 - Testing
baseurl=http://mirror.be10.com/centos/5.0/testing/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
然后更新一次系统，并将yum设置为自启动，让其即时自动为系统更新。
# yum -y update
# chkconfig yum on
# /etc/rc.d/init.d/yum start


加速yum的下载
两个途径可以加速yum的速度，大家可根据情况自己组合使用。
1.使用http-proxy ,  设置方法不说了，就是修改/etc/yum.conf,或者直接在/etc/profile添加以下语句
http_proxy="http://user:password@server ip:3128"
export http_proxy
记得保存后 source该配置文件，使配置生效。
2。使用yum的扩展插件yum-fastestmirror，个人认为这个插件非常有效，速度真的是明显提高，安装只要
yum -y install yum-fastestmirror   就行。
希望通过以上方法，能解除yum的漫长等待过程。
