Redhat5未注册照样升级.doc

Redhat Enterprise 5.4用CentOS 5.5 yum源替换(原创) 2010-11-29 21:22 要使用CentOS的源，就得将RHEL的更新源移除，或是禁用掉，并且需要将RHEL5自带的YUM工具删除。 #cd /etc/yum.repos.d #mv rhel-debuginfo.repo rhel-debuginfo.repo.bak 此处将其备份起来，供意外恢复时使用，删除。如有其他的相关的源设置，都要删除， 或是采用以上方法备份。删除RHEL5自带的YUM及YUM组件： 使用rpm -qa | grep yum列出所有相关的包，把它们都删掉，如果因依赖性不能删除，就使用--nodeps参数删除。 用rpm -qa | grep yum再次查看，如果都没有，就说明都卸载完毕。 下面就可以来进行CentOS源的设置了： 首先，我们需要下载安装CentOS的YUM工具： yum-3.2.22-26.el5.centos.noarch.rpm 下载地址：/i386/CentOS/yum-3.2.22-26.el5.centos.noarch.rpm ??yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm 下载地址： /centos/5.5/os/i386/CentOS/yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm 下载地址： 以上三个都要加安装。 然后复制CentOS5.5的/etc/yum.repos.d下的有且仅有两个的CentOS-Media.repo和CentOS-Base.repo到Redhat Enterprise 5.4相同的目录下。 省的大家再去装CentOS5.5我把这两个文件的内容复制出来，只要保存为同名文件放到/etc/yum.repos.d即可。 的内容： 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-$releasever - Basemirrorlist=/?release=$releaseverarch=$basearchrepo=os#baseurl=/centos/$releasever/os/$basearch/gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5 #released updates [updates]name=CentOS-$releasever - Updatesmirrorlist=/?release=$releaseverarch=$basearchrepo=updates#baseurl=/centos/$releasever/updates/$basearch/gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5 #packages used/produced in the build but not released[addons]name=CentOS-$releasever - Addonsmirrorlist=/?release=$releaseverarch=$basearchrepo=addons#baseurl=/centos/$releasever/addons/$basearch/gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5 #additional packages that may be useful[extras]name=CentOS-$releasever - Extrasmirrorlist=/?release=$releaseverarch=$basearchrepo=extras#baseurl=/centos/$releasever/extras/$basearch/gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5 #additional packages that e
