If you have installed Red Hat Enterprise Linux 7 (RHEL 7) but do not have access to the redhat official repo, you will encounter problems installing and updating software. To solve the above problems, I have prepared a short step to update and install the RPM package from the CD-ROM/DVD-ROM image for RHEL 7. This step can also be used in RHEL 6 or older versions such as RHEL 5. For linux servers that do not have access to the internet or no access to the RHEL official repository, the steps below will help.
1. Mount the ISO from the DVD-ROM into /mnt directory :
[root@rhel7 ~]# mount /dev/cdrom /mnt
2. Take note the media ID :
[root@rhel7 ~]# cat /mnt/media.repo
[InstallMedia] name=RHEL-7.0 Server.x86_64 mediaid=1294067623.154321 metadata_expire=-1 gpgcheck=0 cost=500
3. Create rhel7.repo text file in /etc/yum.repos.d/ with the following content. Make sure you include the correct media ID as above. Save the file :
[root@rhel7 ~]# vi /etc/yum.repos.d/rhel7.repo
[Local-DVD-RHEL7-Repository] mediaid=1294067623.154321 name=DVD-RHEL7 repository baseurl=file:///mnt enabled=1 gpgcheck=0
4. Install, remove and update using yum command.
[root@rhel7 ~]# yum install perl -y
Example :
[root@rhel7 ~]# yum install perl -y .. .. ==================================================================================================== Package Arch Version Repository Size ==================================================================================================== Installing: perl x86_64 4:5.16.3-283.el7 Local-DVD-RHEL7-Repository 8.0 M Installing for dependencies: perl-Carp noarch 1.26-244.el7 Local-DVD-RHEL7-Repository 19 k perl-Encode x86_64 2.51-7.el7 Local-DVD-RHEL7-Repository 1.5 M perl-Exporter noarch 5.68-3.el7 Local-DVD-RHEL7-Repository 28 k perl-File-Path noarch 2.09-2.el7 Local-DVD-RHEL7-Repository 27 k perl-File-Temp noarch 0.23.01-3.el7 Local-DVD-RHEL7-Repository 56 k perl-Filter x86_64 1.49-3.el7 Local-DVD-RHEL7-Repository 76 k perl-Getopt-Long noarch 2.40-2.el7 Local-DVD-RHEL7-Repository 56 k perl-HTTP-Tiny noarch 0.033-3.el7 Local-DVD-RHEL7-Repository 38 k perl-PathTools x86_64 3.40-5.el7 Local-DVD-RHEL7-Repository 83 k perl-Pod-Escapes noarch 1:1.04-283.el7 Local-DVD-RHEL7-Repository 50 k perl-Pod-Perldoc noarch 3.20-4.el7 Local-DVD-RHEL7-Repository 87 k perl-Pod-Simple noarch 1:3.28-4.el7 Local-DVD-RHEL7-Repository 216 k perl-Pod-Usage noarch 1.63-3.el7 Local-DVD-RHEL7-Repository 27 k perl-Scalar-List-Utils x86_64 1.27-248.el7 Local-DVD-RHEL7-Repository 36 k perl-Socket x86_64 2.010-3.el7 Local-DVD-RHEL7-Repository 49 k perl-Storable x86_64 2.45-3.el7 Local-DVD-RHEL7-Repository 77 k perl-Text-ParseWords noarch 3.29-4.el7 Local-DVD-RHEL7-Repository 14 k perl-Time-Local noarch 1.2300-2.el7 Local-DVD-RHEL7-Repository 24 k perl-constant noarch 1.27-2.el7 Local-DVD-RHEL7-Repository 19 k perl-libs x86_64 4:5.16.3-283.el7 Local-DVD-RHEL7-Repository 686 k perl-macros x86_64 4:5.16.3-283.el7 Local-DVD-RHEL7-Repository 42 k perl-parent noarch 1:0.225-244.el7 Local-DVD-RHEL7-Repository 12 k perl-podlators noarch 2.5.1-3.el7 Local-DVD-RHEL7-Repository 112 k perl-threads x86_64 1.87-4.el7 Local-DVD-RHEL7-Repository 49 k perl-threads-shared x86_64 1.43-6.el7 Local-DVD-RHEL7-Repository 39 k .. ..
