RHEL5.4可以直接使用光盤作yum源，而RHEL5.1不能直接用光盤中的源,否則會出現????????urlopen error unknown url type: media，需要改造一番，注意這裡提供的方法不用拷貝光盤中的大量文件.
1.將光盤鏡像掛載到/media/RHEL/目錄下[[email protected] Desktop]#mkdir /media/RHEL
[[email protected] Desktop]#mount /root/rhel5.1.iso /media/RHEL -o loop
2.生成庫文件[[email protected] Desktop]#mkdir /media/yum/
[[email protected] Desktop]#rpm -ivh /media/RHEL/Server/createrepo-0.4.4-2.fc6.noarch.rpm
[[email protected] Desktop]createrepo -o /media/yum/ -g /media/RHEL/Server/repodata/comps-rhel5-server-core.xml /media/RHEL/Server/
[[email protected] Desktop]mount --bind /media/yum/repodate/ /media/RHEL/Server/repodate/
3.生成依賴關系
[[email protected] Desktop]# vim /etc/yum.repos.d/rhel-debuginfo.repo
修改為類似[rhel]
name=Red
baseurl=file:///media/RHEL/Server/
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-RedHat-release[[email protected] Desktop]# yum clean all;yum makecache
RHEL5.1下的本地YUM源就這樣OK了，注意,這裡並沒有拷貝大量的文件，而是掛載.
