对于没接触过Linux的人来说可能不知道源是个什么东西。。不知道也没关系。自己去查。这里简单的说下。源你可以理解成事软件更新加下载的服务器就是了。对于CentOS的源编辑如下1.打开终端输入vi /etc/yum.repos.d/CentOS-Base.repo 打开里面的内容看都不用看直接全删除。然后把下面的内容复制黏贴进去就可以了。一.国内某大学源（电信网通皆可使用）[base]name=CentOS-5 – Base#mirrorlist=http://mirrorlist.centos.org/?release=$releasever5&arch=$basearch&repo=os#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/baseurl=http://ftp.sjtu.edu.cn/centos/5.3/os/$basearch/gpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos6#released updates[update]name=CentOS-5 – Updates#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=updatesbaseurl=http://ftp.sjtu.edu.cn/centos/5.3/updates/$basearch/gpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5#packages used/produced in the build but not released[addons]name=CentOS-5 – Addons#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=addonsbaseurl=http://ftp.sjtu.edu.cn/centos/5.3/addons/$basearch/二. 国内电信源# CentOS-Base.repo## This file uses a new mirrorlist system developed by Lance Davis for CentOS.# The mirror system uses the connecting IP address of the client and the# update status of each mirror to pick mirrors that are updated to and# geographically close to the client. You should use this for CentOS updates# unless you are manually picking other mirrors.## If the mirrorlist= does not work for you, as a fall back you can try the# remarked out baseurl= line instead.##[base]name=CentOS-$releasever – Basebaseurl=http://centos.ustc.edu.cn/centos/$releasever/os/$basearch/gpgcheck=1gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5#released updates[updates]name=CentOS-$releasever – Updatesbaseurl=http://centos.ustc.edu.cn/centos/$releasever/updates/$basearch/gpgcheck=1gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5#packages used/produced in the build but not released[addons]name=CentOS-$releasever – Addonsbaseurl=http://centos.ustc.edu.cn/centos/$releasever/addons/$basearch/gpgcheck=1gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5#additional packages that may be useful[extras]name=CentOS-$releasever – Extrasbaseurl=http://centos.ustc.edu.cn/centos/$releasever/extras/$basearch/gpgcheck=1gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5#additional packages that extend functionality of existing packages[centosplus]name=CentOS-$releasever – Plusbaseurl=http://centos.ustc.edu.cn/centos/$releasever/centosplus/$basearch/gpgcheck=1enabled=0gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-52.之后在终端之下输入yum update 等着更新完之后你就可以开始使用yum了。。在这里同样提供先如今比较深受大众喜爱的Ubuntu源的更新过程1.在终端下输入 vi /etc/apt/sources.list 同样把里面的内容清空。然后去网上找些好用的源。我校园网用过的网易的源算是不错比较快的。把找到的源替换默认内容之后保存退出就可以了。2.终端下输入sudo apt-get update 更新源包头信息3.终端下输入sudo apt-get upgrade 更新你机子中已安装的软件信息之后你就可以使用apt-get install 安装软件了。
