RHEL5.X 替换更新源复制代码代码如下:cd /etc/yum.repos.dwget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repomv CentOS-Base.repo rhel-debuginfo.reporpm –import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
RHEL6.1替换更新源1.移除Yum复制代码代码如下:rpm -aq|grep yum|xargs rpm -e –nodeps
2.下载Yum复制代码代码如下:wget http://mirrors.163.com/centos/6.2/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpmwget http://mirrors.163.com/centos/6.2/os/x86_64/Packages/yum-3.2.29-22.el6.centos.noarch.rpmwget http://mirrors.163.com/centos/6.2/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpmwget http://mirrors.163.com/centos/6.2/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-10.el6.noarch.rpm
3.安装Yum复制代码代码如下:rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpmrpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpmrpm -ivh yum-3.2.29-22.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-10.el6.noarch.rpm
4.更新repo文件，使用网易文件切换目录到 /etc/yum.repos.d/目录下复制代码代码如下:cd /etc/yum.repos.d/wget http://mirrors.163.com/.help/CentOS6-Base-163.repo vi CentOS6-Base-163.repo 编辑文件，把文件里面的$releasever全部替换为版本号，即6 最后保存！或者直接把下面的内存拷贝到CentOS6-Base-163.repo文件中即可（已经修改好）。 复制代码代码如下:# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # 复制代码代码如下: [base] name=CentOS-6 – Base – 163.com baseurl=http://mirrors.163.com/centos/6/os/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=os gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 复制代码代码如下: #released updates [updates] name=CentOS-6 – Updates – 163.com baseurl=http://mirrors.163.com/centos/6/updates/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=updates gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6复制代码代码如下: #additional packages that may be useful [extras] name=CentOS-6 – Extras – 163.com baseurl=http://mirrors.163.com/centos/6/extras/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=extras gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 复制代码代码如下: #additional packages that extend functionality of existing packages [centosplus] name=CentOS-6 – Plus – 163.com baseurl=http://mirrors.163.com/centos/6/centosplus/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=centosplus gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 复制代码代码如下: #contrib – packages by Centos Users [contrib] name=CentOS-6 – Contrib – 163.com baseurl=http://mirrors.163.com/centos/6/contrib/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=contrib gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
5.最后一步复制代码代码如下:yum clean all #清理yum缓存 yum makecache #将服务器上的软件包信息缓存到本地，以提高搜索安装软件的速度。yum list yum #测试配置的yum源是否已经生效。
