How to create local repositoy RHEL 6

As in the post How to create local repositoy SLES 10 we also can do the same thing on RHEL (Redhat Enterprise Linux) 6 using yum. Here are the steps :

1. Install the createrepo package:
2. Copy all of the packages into one directory, such as /home/choirul/local_repo/ 
3. Run the createrepo --database command on that directory:
   

   createrepo --database /home/choirul/local_repo

4. Create a new file in /etc/yum.repos.d, with the following contents:
   

   # cat /etc/yum.repos.d/local.repo
   [local]
   name=Repository from DVD
   baseurl=file:/home/choirul/local_repo/
   enabled=1
   gpgcheck=1
   gpgkey=file:/home/choirul/local_repo/RPM-GPG-KEY-release

5. update yum with command
   

   yum clean all
   yum update
   yum list

6. You can find file RPM-GPG-KEY-release in root directory of RHEL DVD

The above step is for repository that locate in folder. Beside, we also can create repositoy using iso file. Here are the steps :

1. create mount point for repository :

   mkdir -p /path/to/repo

2. Mount iso file on the mount point that you just created

   mount -r -t iso9660 -o loop /path/to/image/file.iso /path/to/repo

3. If you use your cd/dvd drive, you must know where is your drive located. To know that see Linux Sysinfo command. Use this command to mount your drive

   mount -r -t iso9660 /dev/device_name /path/to/repo

4. Choose a name for the repo file and open it as a new file

   vi /etc/yum.repos.d/dvd.repo

5. Supply the details of the repository. For example:

   [dvd]
   name=ISO
   baseurl=file:///mnt/repo/Server
   enabled=1
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
   

6. update yum

If for some reasons you need to install library, you can use command yum whatprovides [library_name] as below:

[root@short Downloads]# yum whatprovides libQtGui.so.4
Loaded plugins: presto, refresh-packagekit
1:qt-x11-4.5.3-7.fc12.i686 : Qt GUI-related libraries

Matched from:
Other       : libQtGui.so.4
[root@short Downloads]# yum install qt-x11-4.5.3-7.fc12.i686
