[root@localhost ]# mkdir bak
#Move the original yum repositories to the bak directory
[root@localhost ]# mv *.repo bak
#Enter the bak directory
[root@localhost ]# cd bak
# Copy the CD-ROM yum source files to the /etc/ directory
[root@localhost bak]# cp ...
# Return to the /etc/ directory
[root@localhost bak]# cd ...
#Open the CD-ROM yum source file
[root@localhost ]# vim
# vim
...... omit part of ......
# yum --disablerepo=\* --enablerepo=c6-media [command]
[c6-media]
