       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.1

2.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.rpm

3.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
[root@akinlau ~] cd yum-3.4.3

[root@akinlau yum-3.4.3] ./yummain.py install yum

base                                                         | 3.7 kB     00:00    

base/primary_db                                              | 4.5 MB     00:07    

extras                                                       | 3.5 kB     00:00    

extras/primary_db                                            |  23 kB     00:03

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://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.i686.rpm

x86_64:

wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

EL 5:

i386:

wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm

x86_64:

wget http://pkgs.repoforge.org/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://mirrorlist.centos.org/?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
