Linux system, set up a local CD yum source

Setting up a local CD yum source

• Step: CentOS installation into the disc, and the disc mount to the specified location; command is as follows:

[root@localhost ~]#mkdir /mnt/cdrom
#创建cdrom目录，作为光盘的挂载点
[root@localhost ~]#mount -t iso9660 /dev/cdrom1 /mnt/cdrom/
mount: block device /dev/sr0 is write-protected mounting read-only
#挂载光盘到/mnt/cdrom目录下

• Step Two: New bak directory, * .repo file to the backup folder backup, because only the extension is "* .repo" yum source file to a configuration file. Of course, you can also delete a few other yum source profile, but if you delete, when you want to use the network as a source yum, there is no reference file. Command is as follows:

[root@localhost ~]#cd /etc/yum.repos.d/
[root@localhost yum.repos.d]#mv *.repo /backup/

• The third step: modifying the source profile disc yum CentOS-Media.repo, with reference to the following modified method:

[root@localhost ~]# vim /etc/yum.repos.d/backup/CentOS-Media.repo
[c6-media]
name=CentOS-$releasever - Media
baseurl=file:///media/CentOS_6.6_Final/
        file:///media/cdrom/
        file:///dev/cdrom1
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

• Step four: Clear the cache yum

[root@localhost yum.repos.d]# yum clean all
已加载插件：fastestmirror, refresh-packagekit, security
Cleaning repos: demo
清理一切

• Step five: the package information is downloaded to the local computer server cached

[root@localhost yum.repos.d]# yum makecache
已加载插件：fastestmirror, refresh-packagekit, security
