    1、查看当前Linux操作系统RedHat 版本号与32/64位操作系统。

    [root@localhost CentOS5]# more /etc/redhat-release  Red Hat Enterprise Linux Server release 5.8 (Tikanga) [root@localhost centos5]# uname -a Linux localhost.localdomain 2.6.18-308.el5 #1 SMP Fri Jan 27 17:17:51 EST 2012 x86_64 x86_64 x86_64 GNU/Linux

    2、删除RedHat自带的yum服务

    [root@localhost centos5]# rpm -qa|grep yum |xargs rpm -e --nodeps

    3、下载相应的yum 安装包并安装(安装包个数因操作系统版本号不同会有存在差异)

    [root@localhost centos5]# wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-3.2.22-40.el5.centos.noarch.rpm [root@localhost centos5]# wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm [root@localhost centos5]# wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-4.el5.x86_64.rpm                 [root@localhost centos5]# rpm -ivh yum*.rpm

    4、配置yum源(推荐使用的是163的镜像)

    [root@localhost centos5]# vi /etc/yum.repos.d/CenOS-Base.repo

    添加以下内容:

    # CentOS-Base.repo # # 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-$releasever - Base #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os baseurl=http://mirrors.163.com/centos/5/os/x86_64/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/5/os/x86_64/RPM-GPG-KEY-CentOS-5

    #released updates  [updates] name=CentOS-$releasever - Updates #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates baseurl=http://mirrors.163.com/centos/5/updates/x86_64/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/5/os/x86_64/RPM-GPG-KEY-CentOS-5

    #additional packages that may be useful [extras] name=CentOS-$releasever - Extras #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras baseurl=http://mirrors.163.com/centos/5/extras/x86_64/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/5/os/x86_64/RPM-GPG-KEY-CentOS-5

    #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus baseurl=http://mirrors.163.com/centos/5/centosplus/x86_64/ gpgcheck=1 enabled=0 gpgkey=http://mirrors.163.com/centos/5/os/x86_64/RPM-GPG-KEY-CentOS-5

    #contrib - packages by Centos Users [contrib] name=CentOS-$releasever - Contrib #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=contrib baseurl=http://mirrors.163.com/centos/5/contrib/x86_64/ gpgcheck=1 enabled=0 gpgkey=http://mirrors.163.com/centos/5/os/x86_64/RPM-GPG-KEY-CentOS-5

    5、清除缓存并下载新的镜像缓存

    [root@localhost centos5]# yum clean all [root@localhost centos5]# yum makecache

    6、测试(查看当前subversion版本与检查服务器subversion版本)

    [root@localhost yum.repos.d]# rpm -qa|grep subversion subversion-1.6.11-7.el5_6.4 subversion-1.6.11-7.el5_6.4                                                                                                                              [root@localhost yum.repos.d]# yum check-update subversion Loaded plugins: fastestmirror, katello, product-id, subscription-manager Updating certificate-based repositories. Unable to read consumer identity Loading mirror speeds from cached hostfile

    subversion.i386                                                                                    1.6.11-12.el5_10                                                                            base     subversion.x86_64                                                                                  1.6.11-12.el5_10                                                                            base     Obsoleting Packages centos-release.x86_64                                                                              10:5-11.el5.centos                                                                          base     redhat-release.x86_64                                                                          5Server-5.8.0.3                                                                              installed firefox.i386                                                                                      31.3.0-4.el5.centos                                                                          updates   firefox.i386                                                                                  3.6.26-1.el5_7                                                                              installed firefox.x86_64                                                                                    31.3.0-4.el5.centos                                                                          updates   firefox.x86_64                                                                                3.6.26-1.el5_7                                                                              installed

    7、安装yum注意问题

    根据Linux 的版本号安装相应的CentOS并引用CentOS版本号对应的CenOS-Base.repo文件,

    (1)、如果安装了CentOS 5的yun,却引用CentOS6的源yum makecache时就会报错。

    (2)、如果操作系统是RedHat 5,却安装 CentOS6 yum会导致安装时需要手动安装与升级大量的依赖包。
