公司提供的CentOS VM中，/etc/yum.repos.d 下 只有一個build.repo，其中提供的yum 源只有公司內(nèi)部的幾個源，很多包在這些源中都找不到。于是要添加別的源，下面的帖子中介紹了如何在CentOS中添加中科大、搜狐和163的yum源：http://www.husw.net/blog/post/1386/。摘錄如下：

本文章介紹的yum源支持的版本是CentOS 6系列，理論上支持RHEL6系列。
更新方法如下：
先進(jìn)入yum源配置目錄

cd /etc/yum.repos.d

?

備份系統(tǒng)自帶的yum源

mv CentOS-Base.repo CentOS-Base.repo.save

下載其他更快的yum源
中科大的yum源：

wget http://centos.ustc.edu.cn/CentOS-Base.repo

163的yum源：

wget http://mirrors.163.com/.help/CentOS-Base-163.repo

sohu的yum源

wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo

更新完yum源后，建議更新一下，使操作立即生效

yum makecache [yasi]: 在執(zhí)行最后一步，即yum makecache的時候，遇到錯誤： Loaded plugins: fastestmirror Repository base is listed more than once in the configuration Repository updates is listed more than once in the configuration Repository extras is listed more than once in the configuration Repository centosplus is listed more than once in the configuration Repository contrib is listed more than once in the configuration Loading mirror speeds from cached hostfile * addons: mirrors.163.com * base: mirror.metrocast.net * extras: mirror.beyondhosting.net * fasttrack: centos.vipernetworksystems.com * updates: centos.vipernetworksystems.com http://mirrors.163.com/centos/6/addons/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404" Trying other mirror. http://mirror.centos.org/centos/6/addons/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404" Trying other mirror. Error: Cannot retrieve repository metadata (repomd.xml) for repository: addons. Please verify its path and try again 原因是，http://mirrors.163.com/centos/6/addons/x86_64/repodata/repomd.xml和?http://mirror.centos.org/centos/6/addons/x86_64/repodata/repomd.xml?確實不存在，可能被更新掉了。解決辦法是，找到可用的URL替換之，或者把相應(yīng)的.repo文件中的項整個注釋掉。這里我采用后者。 例如，在CentOS-Base-163.repo中，注釋掉整個addon項 #[addons] #name=CentOS-$releasever - Addons - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=addons #baseurl=http://mirrors.163.com/centos/$releasever/addons/$basearch/ #gpgcheck=1 #pgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5 在CentOS-Base-sohu.repo中注釋掉下面的內(nèi)容 #[addons] #name=CentOS-$releasever - Addons - sohu.com #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=addons #baseurl=http://mirrors.sohu.com/centos/$releasever/addons/$basearch/ #gpgcheck=1 #gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5CentOS-Base-sohu.repo 然后，再執(zhí)行yum makecache。之后，yum就可以找到我要安裝的包了，比如gdb, subversion, gcc-c++ 等。 注意： 有時用yum list xxx找不到某個包，可用嘗試用yum search xxx。 如，yum list vim 就報告?Error: No matching Packages to list。而 yum search vim 則返回： vim-X11.x86_64 : The VIM version of the vi editor for the X Window System vim-common.x86_64 : The common files needed by any version of the VIM editor vim-enhanced.x86_64 : A version of the VIM editor which includes recent enhancements vim-minimal.x86_64 : A minimal version of the VIM editor

使用?yum 程序安裝所需開發(fā)包（以下為標(biāo)準(zhǔn)的rpm包名稱）
yum install gcc gcc-c++ gcc-g77 flex bison autoconf automake bzip2-devel zlib-devel ncurses-devel libjpeg-devel libpng-devel libtiff-devel freetype-devel pam-devel openssl-devel libxml2-devel gettext-devel pcre-devel mysql-devel net-snmp-devel curl-devel perl-DBI

?

執(zhí)行yum源更新

[root@localhost ~]# yum clean all [root@localhost ~]# yum makecache [root@localhost ~]# yum update

?注意：

更新為163的源后,yum的時候報錯:GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5.

解決方案:vi /etc/yum.repos.d/CentOS-Base.repo?

把文件里所有的RPM-GPG-KEY-CentOS-5更改為RPM-GPG-KEY-CentOS-6就可以了

vim 替換 :%s/RPM-GPG-KEY-CentOS-5/RPM-GPG-KEY-CentOS-6
