首先
[root@mode media]# cd /etc/yum.repos.d/[root@mode yum.repos.d]# lltotal 16-rw-r–r– 1 root root 560 Dec 19 01:20 CentOS-Media.repodrwxr-xr-x 2 root root 4096 Dec 18 20:03 bakdrwxr-xr-x 2 root root 4096 Jan 28 19:17 ncurses-develdrwxr-xr-x 2 root root 4096 Mar 12 18:32 openssl-devel[root@mode yum.repos.d]# cat CentOS-Media.repo # 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] [c5-media]name=CentOS-$releasever – Mediabaseurl=file:///mnt/cdrom/gpgcheck=1enabled=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5看到CentOS-Media.repo中的 baseurl=file:///mnt/cdrom/了吗
如果指定了CentOS-meida源，系统会根据路径查找安装 所需要的包
然后创建目录文件，，将镜像挂载到那个目录中
、[root@mode yum.repos.d]# mkdir -p /mnt/cdrom[root@mode yum.repos.d]# mount -o loop /dev/cdrom /mnt/cdrom然后就可以安装需要安装的软件了：
[root@mode yum.repos.d]# yum –disablerepo=\* –enablerepo=c5-media install xinetdLoaded plugins: fastestmirror, securityLoading mirror speeds from cached hostfileSetting up Install ProcessResolving Dependencies–> Running transaction check—> Package xinetd.x86_64 2:2.3.14-16.el5 set to be updated–> Finished Dependency ResolutionDependencies Resolved======================================================================================================================================================================= PackageArchVersionRepositorySize=======================================================================================================================================================================Installing: xinetdx86_642:2.3.14-16.el5c5-media127 kTransaction Summary=======================================================================================================================================================================Install1 Package(s)Upgrade0 Package(s)Total download size: 127 kIs this ok [y/N]: yDownloading Packages:Running rpm_check_debugRunning Transaction TestFinished Transaction TestTransaction Test SucceededRunning Transaction Installing: xinetd1/1 Installed: xinetd.x86_64 2:2.3.14-16.el5Complete![root@mode yum.repos.d]#
自己战胜自己是最可贵的胜利。
