centos6 可用的网络yum 源
安装环境：VPS,CentOS 6 + devel包
一、安装相应的软件
1.安装python
下载Python源码包
[root@akinlau ~]# wget http://www.python.org/ftp/python/2.4.3/Python-2.4.3.tar.bz2
解压Python源码包
[root@akinlau ~]# tar jxvf Python-2.4.3.tar.bz2
编译安装Python
[root@akinlau ~]# cd Python-2.4.3 [root@akinlau Python-2.4.3]# ./configure checking MACHDEP... linux2 checking EXTRAPLATDIR... checking for --without-gcc... no checking for --with-cxx=... no checking for c++... c++ checking for /dev/ptmx... yes checking for /dev/ptc... no checking for socklen_t... yes checking for build directories... done configure: creating ./config.status config.status: creating Makefile.pre config.status: creating Modules/Setup.config config.status: creating pyconfig.h creating Setup creating Setup.local creating Makefile [root@akinlau Python-2.4.3]# make [root@akinlau Python-2.4.3]# make install running install_scripts copying build/scripts-2.4/smtpd.py -> /usr/local/bin copying build/scripts-2.4/pydoc -> /usr/local/bin copying build/scripts-2.4/idle -> /usr/local/bin changing mode of /usr/local/bin/smtpd.py to 755 changing mode of /usr/local/bin/pydoc to 755 changing mode of /usr/local/bin/idle to 755 if test -f /usr/local/bin/python -o -h /usr/local/bin/python; then rm -f /usr/local/bin/python; else true; fi (cd /usr/local/bin; ln python2.4 python) Creating directory /usr/local/man Creating directory /usr/local/man/man1 /usr/bin/install -c -m 644 ./Misc/python.man /usr/local/man/man1/python.12.下载并安装python-urlgrabber，python-pycurl，yum-metadata-parser
[root@akinlau ~] wget http://tel.mirrors.163.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-8.el6.noarch.rpm [root@akinlau ~] wget http://tel.mirrors.163.com/centos/6/os/x86_64/Packages/python-pycurl-7.19.0-8.el6.x86_64.rpm [root@akinlau ~] wget http://tel.mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm [root@akinlau ~] rpm -ivh python-urlgrabber-3.9.1-8.el6.noarch.rpm python-pycurl-7.19.0-8.el6.x86_64.rpm yum-metadata-parser-1.1.2-16.el6.x86_64.rpm3.创建yum配置文件
[root@akinlau ~] touch /etc/yum.conf
4.下载yum源码包并安装
[root@akinlau ~] wget http://yum.baseurl.org/download/3.4/yum-3.4.3.tar.gz
解压源码包
[root@akinlau ~] tar zxvf yum-3.4.3.tar.gz
编译安装yum
出现以上提示就证明yum已经安装成功了。
二、配置yum源(建议使用国内的163和sohu源，速度比较快)
1.网易(163) yum源
下载对应版本repo文件, 放入/etc/yum.repos.d/(操作前请做好相应备份)
CentOS5 wget http://mirrors.163.com/.help/CentOS5-Base-163.repo CentOS6 wget http://mirrors.163.com/.help/CentOS6-Base-163.repo运行yum makecache生成缓存
2.搜狐(sohu) yum 源
下载CentOS-Base-sohu.repo, 放入/etc/yum.repos.d/
wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo
运行yum makecache生成缓存
3.EPEL源
下载相应的RPM包安装
第6版企业版 Linux
wget http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
第5版企业版 Linux
wget http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
4.RPMForge源
下载对应系统版本的RPM包安装
EL 6:
i686:
wget http:///rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.i686.rpm
x86_64:
wget http:///rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
EL 5:
i386:
wget http:///rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm
x86_64:
wget http:///rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm
163和sohu的源直接下载相应的repo文件放到/etc/yum.repos.d/目录，然后运行yum makecache生成缓存就可以使用
EPEL源和RPMForge源（国外的yum源）都是下载相应的RPM包安装后会自动在/etc/yum.repos.d/目录下生成相应的repo文件，然后运行yum makecache生成缓存就可以使用
不建议多种源一起用，一般情况下一个官方标准源加一个上面的其中一个源就足够用了，以上源对CentOS等系统完全兼容，但各软件库之间并不能保证完全兼容没有冲突。如果您需要同时使用以上源，您需要安装yum-priorities插件。安装yum-priorities插件后，您可以给各个源设置优先级priority。一般设置官方标准源优先级为1，最高，第三方源推荐>10（priority=N （N为1到99的正整数，数值越小越优先）。如果不想使用某个源的话可以在repo文件中设置 enabled=0不启用该源，如果想启用设成enabled=1就可以了。
下面以官方标准源：CentOS-Base.repo为例子，说明一下主要的设置选项：
[base] //软件源的名称，将被yum取得并识别 name=CentOS-$releasever - Base //定义软件仓库的名称,没实际作用 mirrorlist=http:///?release=$releasever&arch=$basearch&repo=os //mirrorlist指定镜像服务器的地址列表 #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ //baseurl指定一个源的镜像服务器地址,这里加了#表示注释了yum将忽略这一行 priority=1 //设置源优先级,1到99的正整数，数值越小越优先 enabled=0 //这个选项表示是否启用repo中定义的这个源，0为禁用，1为启用 gpgcheck=1 //这个选项表示是否要对下载的rpm包进行gpg的校验，来确定rpm包的来源是有效和安全的，跟下面的gpgkey成对使用 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 //定义用于校验的gpg密钥
