在CentOS系统中，yum是个好东西，一组件可以直接通过yum来安装，但系统默认的yum源速度往往不尽人意，为了达到快递安装的目的，在这里就需要修改yum源

中科大的Centos 开源镜像站点.

执行以下命令就可以了

cd /etc/yum.repos.d

mv CentOS-Base.repo CentOS-Base.repo.bak

wget

mv CentOS-Base.repo.5 CentOS-Base.repo

cat CentOS-Base.repo

[base]
name=CentOS-$releasever - Base
baseurl=centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=centos/RPM-GPG-KEY-CentOS-5

#released updates
[updates]
name=CentOS-$releasever - Updates
baseurl=centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=centos/RPM-GPG-KEY-CentOS-5

#packages used/produced in the build but not released
[addons]
name=CentOS-$releasever - Addons
baseurl=centos/$releasever/addons/$basearch/
gpgcheck=1
gpgkey=centos/RPM-GPG-KEY-CentOS-5

#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
baseurl=centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=centos/RPM-GPG-KEY-CentOS-5

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
baseurl=centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=centos/RPM-GPG-KEY-CentOS-5

也可以使用，
