3,建立yum 源
CentOS-Base.repo改名
yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak
備份建立光碟repo配置檔案，名稱可自取配置檔案，名稱可自取
yum.repos.d]# cp CentOS-Media.repo CentOS-Media.repo.bak
修改光碟repo配置檔案，名稱可自取
yum.repos.d]# vim CentOS-Media.repo
# CentOS-Media.repo # # This repo can be used with mounted DVD media, verify the mount point for # CentOS-6. 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=c6-media [command] # # or for ONLY the media repo, do this: #
# yum --disablerepo=\* --enablerepo=c6-media [command]
[c6-media]
name=CentOS-$releasever - Media
baseurl=file:///mnt/cdrom/
# file:///media/cdrom/
# file:///media/cdrecorder/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
4，載入yum源
~]# yum clean all
