RedHat Enterprise Linux 6.0（32位）如何使用CentOS YUM...

        因为 redhat的yum在线更新是收费的，若是没有注册的话不能使用，若是要使用，需将redhat的yum卸载后，重启安装，再配置其余源，如下为详细过程：  一、删除redhat原有的yum  rpm -aq|grep yum|xargs rpm -e --nodeps 二、下载yum安装文件 wget http://tel.mirrors.163.com/centos/6.4/os/i386/Packages/yum-3.2.29-40.el6.centos.noarch.rpm wget http://tel.mirrors.163.com/centos/6.4/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm wget http://tel.mirrors.163.com/centos/6.4/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm wget http://tel.mirrors.163.com/centos/6.4/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm 三、进行安装yum rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm rpm -ivh yum-metadata-parser-1.1.2-16.el6.i686.rpm rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm 注意最后两个包必需同时安装，不然会相互依赖. 四、更新repo文件 mv /etc/yum.repos.d/rhel-debuginfo.repo /etc/yum.repos.d/rhel-debuginfo.repo.repo.bak vi /etc/yum.repos.d/rhel-debuginfo.repo 内容为： [base] name=CentOS-$releasever - Base baseurl=http://mirrors.163.com/centos/6.4/os/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6 #released updates [updates] name=CentOS-$releasever - Updates baseurl=http://mirrors.163.com/centos/6.4/updates/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6 #packages used/produced in the build but not released #[addons] #name=CentOS-$releasever - Addons #baseurl=http://mirrors.163.com/centos/$releasever/addons/$basearch/ #gpgcheck=1 #gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras baseurl=http://mirrors.163.com/centos/6.4/extras/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus baseurl=http://mirrors.163.com/centos/6.4/centosplus/$basearch/ gpgcheck=1 enabled=0 五、yum clean all 六、yum update 七、yum install vim #测试一下可不能够用  【设置本地镜像做为yum源】 一、mkdir /mnt/cdrom 2 mount /dev/cdrom /mnt #挂着镜像，光盘 3 vi /etc/yum.repos.d/rhel-debuginfo.repo #编辑repo文件 添加一下内容： [rhel_6_iso] name=local iso baseurl=file:///mnt gpgcheck=1 gpgkey=file:///mnt/RPM-GPG-KEY-redhat-release
