见识了yum的缓慢,有人说yum就是郁闷,用惯了apt用yum还真是郁闷,关键是速度...速度就是效率阿. 在/etc/yum.repos.d/目录下，有两个文件 CentOS-Base.repo和CentOS-Media.repo 其中CentOS-Base.repo记录着网络上的yum源的地址和路径信息等 CentOS-Media.repo记录着可以从本地作为yum源的介质和路径。其中还有这样一个说明：  # CentOS-Media.repo # # This repo is used to mount the default locations for a CDROM / DVD on # CentOS-5. You can use this repo and yum to install items directly off the # DVD ISO that we release. # # To use this repo, put in your DVD and use it with the other repos too: # yum --enablerepo=c5-media [command] # # or for ONLY the media repo, do this: # # yum --disablerepo=* --enablerepo=c5-media [command] PS: 这个文件内原本是 baseurl=file:///media/CentOS/ file:///media/cdrom/ file:///media/cdrecorder/ 这个的CentOS就是你光盘挂载过来在/media目录中的名字,我起先没改就error了.我的光盘是CentOS_5.2_Final,改为 baseurl=file:///media/CentOS_5.2_Final/ file:///media/cdrom/ file:///media/cdrecorder/ 就OK了,根据自己实际情况改.... 觉得自己的光盘的源足够用了。不需要网络源，或者没有网络。 可以使用yum --disablerepo=\* --enablerepo=c5-media [command] 但是使用命令时如果这样 [root@centos yum.repos.d]# yum --enablerepo=c5-media Loading "installonlyn" plugin You need to give some command 这不是一个完整的命令，须在后面加上要执行的命令。这部分只是告诉你这条yum命令允许使用本地media介质的源而已。正确的命令如下： [root@centos cdrom]# [color="#ff0000"]yum [color="#ff0000"]--disablerepo[color="#ff0000"]=[color="#ff0000"]* --[color="#ff0000"]enablerepo=[color="#ff0000"]c5-[color="#ff0000"]media update Loading "installonlyn" plugin Setting up Update Process Setting up repositories c5-media 100% |=========================| 1.1 kB 00:00 Reading repository metadata in from local files primary.xml.gz 100% |=========================| 834 kB 00:00 ################################################## 2400/2400 No Packages marked for Update/Obsoletion 比如安装gdb [root@centos cdrom]# [color="#ff0000"]yum [color="#ff0000"]--[color="#ff0000"]disablerepo[color="#ff0000"]=* [color="#ff0000"]--[color="#ff0000"]enablerepo[color="#ff0000"]=[color="#ff0000"]c5[color="#ff0000"]-[color="#ff0000"]media install gdb Loading "installonlyn" plugin Setting up Install Process Setting up repositories Reading repository metadata in from local files Parsing package install arguments Resolving Dependencies --> Populating transaction set with selected packages.
