Tag: CentOS 6

In this article, I will share about how to update and install RPM packages from the image CD-ROM/DVD-ROM in Red Hat Enterprise Linux 6 (RHEL 6). This step can also be used on CentOS 6 or older versions such as CentOS 5. It would be very useful if the server you have a slow internet connection, or no internet connection. Instead of using internet connection directly to RHEL repositories registered, it is possible to use the Local CD/DVD- ROM as your yum repository. There are two methods to install and configure local yum repository RHEL 6. Both methods have been tested and works well on Linux RHEL 6 server. You can choose whichever method you choose :

Method 1:
1. Insert DVD/ISO into DVD-Drive.
2. Mount the ISO from the DVD-ROM into /mnt directory :

[root@rhel6 ~]# mount /dev/cdrom /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only

3. Check the existing partition on your RHEL 6 server :

[root@rhel6 ~]# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/VolGroup-lv_root
                       9845280   1328824   8016336  15% /
tmpfs                   515660         0    515660   0% /dev/shm
/dev/sda1               495844     28689    441555   7% /boot
/dev/sr0               2862360   2862360         0 100% /mnt

4. Go to /mnt and check current directory :

[root@rhel6 ~]# cd /mnt
[root@rhel6 mnt]# pwd
/mnt

5. List out what is in DVD.

[root@rhel6 mnt]# ls

6. Read what is in media.repo. Take note on the mediaid :

[root@rhel6 mnt]# cat media.repo

[InstallMedia]
name=Red Hat Enterprise Linux 6.0
mediaid=1235481171.125642
metadata_expire=-1
gpgcheck=0
cost=500

7. Create dvdrhel.repo text file in /etc/yum.repos.d/ with the following content. Please create something as follow:

[root@rhel6 ~]# vi /etc/yum.repos.d/dvdrhel.repo

[DVD-RHEL6-Repository]
mediaid=1235481171.125642
name=DVD-RHEL6 repository
baseurl=file:///mnt/Server
enabled=1
gpgcheck=0

8. Finish. You can start install, remove and update using yum command :

Method 2 :
1. Check the existing partition on your RHEL 6 server :

[root@rhel6 ~]# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/VolGroup-lv_root
                       9845280   1221632   8123528  14% /
tmpfs                   515660         0    515660   0% /dev/shm
/dev/sda1               495844     28689    441555   7% /boot

2. Create repo directory in /media :

[root@rhel6 ~]# mkdir /media/repo

3. Create 1 2 3 directory in /media/repo :

[root@rhel6 ~]# mkdir -p /media/repo/{1,2,3}

4. Mount the ISO from the DVDROM into /media/repo/1 directory :

[root@rhel6 ~]# mount -o loop /dev/cdrom /media/repo/1

[root@rhel6 ~]# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/VolGroup-lv_root
                       9845280   1221644   8123516  14% /
tmpfs                   515660         0    515660   0% /dev/shm
/dev/sda1               495844     28689    441555   7% /boot
/dev/loop0             2862360   2862360         0 100% /media/repo/1

5. Create temporary repo folder under /tmp to put required rpm’s packages for createrepo installation :

[root@rhel6 ~]# mkdir /tmp/repo 

6. Copy the require packages to install create repo :

[root@rhel6 ~]# cp /media/repo/1/Packages/createrepo* /tmp/repo
[root@rhel6 ~]# cp /media/repo/1/Packages/deltarpm* /tmp/repo
[root@rhel6 ~]# cp /media/repo/1/Packages/python-deltarpm* /tmp/repo

7. Install the rpm packages using below command :

[root@rhel6 ~]# rpm -ivh /tmp/repo/*
warning: /tmp/repo/createrepo-0.9.8-4.el6.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY

   1:deltarpm               ########################################### [ 33%]
   2:python-deltarpm        ########################################### [ 67%]
   3:createrepo             ########################################### [100%]

8. Go to /media/repo directory :

[root@rhel6 ~]# cd /media/repo/
[root@rhel6 repo]# pwd
/media/repo

9. Run createrepo command :

[root@rhel6 repo]# createrepo .
