Redhat EL5.4用CentOS源进行更新

Redhat EL5.4用CentOS源进行更新 1.备份或删除yum源配置文件 #cd /etc/yum.repos.d #mv rhel-debuginfo.repo rhel-debuginfo.repo.bak 2.编辑CentOS-Base.repo,填入以下内容 [base] name=CentOS-5 - Base repo=os baseurl=http://centos.ustc.edu.cn/centos/5/os/$basearch/ gpgcheck=1 gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 [update] name=CentOS-5 - Updates baseurl=http://centos.ustc.edu.cn/centos/5/updates/$basearch/ gpgcheck=1 gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 [addons] name=CentOS-5 - Addons baseurl=http://centos.ustc.edu.cn/centos/5/addons/$basearch/ gpgcheck=1 gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 [extras] name=CentOS-5 - Extras baseurl=http://centos.ustc.edu.cn/centos/5/extras/$basearch/ gpgcheck=1 gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 [centosplus] name=CentOS-5 - Plus baseurl=http://centos.ustc.edu.cn/centos/5/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 [contrib] name=CentOS-5 - Contrib baseurl=http://centos.ustc.edu.cn/centos/5/contrib/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 3.从http://centos.ustc.edu.cn/centos/5.4/os/i386/CentOS/下载以下文件并安装 yum-fastestmirror-1.1.16-13.el5.centos.noarch.rpm yum-3.2.22-20.el5.centos.noarch.rpm yum-updatesd-0.9-2.el5.noarch.rpm 或者找个FTP站点用wget下载： #wget ftp://ftp.pdc.kth.se/pub/bambi/centos/5.4/os/i386/CentOS/yum-fastestmirror-1.1.16-13.el5.centos.noarch.rpm #wget ftp://ftp.pdc.kth.se/pub/bambi/centos/5.4/os/i386/CentOS/yum-3.2.22-20.el5.centos.noarch.rpm #wget ftp://ftp.pdc.kth.se/pub/bambi/centos/5.4/os/i386/CentOS/yum-updatesd-0.9-2.el5.noarch.rpm #rpm -ivh yum*.rpm 4.如果http://centos.ustc.edu.cn/centos这个服务器的CentOS映像不够快的话用自己适合的服务器替换，可以用IE上去先看看 5.导入KEY文件，注意大小写 rpm --import http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5 6.测试 #yum list 注意：因为需要解析域名，所以需要先配置好DNS，不建议直接用IP地址
