一、如何设置CentOS 5的yum源为上海交通大学网站 一。如何设置CentOS 5的yum源为上海交通大学网站 1．修改/etc/yum.repos.d/CentOS-Base.repo为: #mirrorlist=http://mirrorlist.centos.org/?release=$releasever5&arch=$basearch& #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ baseurl=http://ftp.sjtu.edu.cn/centos/5.0/os/$basearch/ gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=updates baseurl=http://ftp.sjtu.edu.cn/centos/5.0/updates/$basearch/ gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #packages used/produced in the build but not released #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=addons baseurl=http://ftp.sjtu.edu.cn/centos/5.0/addons/$basearch/ gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #additional packages that may be useful #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=extras baseurl=http://ftp.sjtu.edu.cn/centos/5.0/extras/$basearch/ gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #additional packages that extend functionality of existing packages #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=centosplus baseurl=http://ftp.sjtu.edu.cn/centos/5.0/centosplus/$basearch/ gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 #contrib - packages by Centos Users #mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=contrib baseurl=http://ftp.sjtu.edu.cn/centos/5.0/contrib/$basearch/ gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5 # 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. baseurl=http://mirror.be10.com/centos/5/os/i386/ baseurl=http://mirror.be10.com/centos/5/updates/i386/ #packages used/produced in the build but not released baseurl=http://mirror.be10.com/centos/5/addons/i386/ #additional packages that may be useful baseurl=http://mirror.be10.com/centos/5/extras/i386/ #additional packages that extend functionality of existing packages baseurl=http://mirror.be10.com/centos/5/centosplus/i386/ #contrib - packages by Centos Users baseurl=http://mirror.be10.com/centos/5/contrib/i386/ baseurl=http://mirror.be10.com/centos/5/testing/i386/ 不知道大家有没有和我一样尝试使用rsync 同步mirrors.kernel.org/CentOS，总计超过6G的数据在只有30-50KB/s的速度下传输，也许需要3-5天才可以完成。怎么办？使用国内的服务器吧，但是他们只提供yum源更新，也就是只能使用http访问，而不提供rsync server。 这是我找到的一个速度不错的CentOS 4/5 yum源:218.201.144.68 以上命令会从网络上抓取2.6G左右的数据，会运行很长时间，你完全可以去做其它的工作。完成后，使用ls命令看看我们获取到的数据，我们只需要保留i386目录下面的数据，将其移动到opt，并将下载时产生的index.html?之类文件一并删除 cd /opt/CentOS/218.201.144.68/centos/5/os/ find CentOS5 -name index.htm?\* -exec rm -f{}\; 下一步配置yum更新源。CentOS已经在/etc/yum.repos.d下面创建了CentOS-Media.repo，对该文件做适应修改就可以使用。以下是修改结果 [root@localhost etc]# cat yum.repos.d/CentOS-Media.repo # This repo is used to mount the default locations for a CDROM / DVD on # CentOS-5. You can use this repo and yum to install items directly off the # DVD ISO that we release. # To use this repo, put in your DVD and use it with the other repos too: # yum --enablerepo=c4-media [command] # or for ONLY the media repo, do this: # yum --disablerepo=\* --enablerepo=c4-media [command] name=CentOS-$releasever - Media baseurl=file:///opt/CentOS # file:///media/cdrecorder/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-beta 现在就可以使用yum check-update来测验一下本地源了。如果在没有连接网络情况，最好把yum.repos.d目录下面的其它repo文件适当更名，这样yum就只使用本地源，速度得以提升。 本文转自king_819 51CTO博客，原文链接：http://blog.51cto.com/kerry/102807，如需转载请自行联系原作者
