Setup yum repositories to update or install package from Local ISO Image

Creation of yum repositories is handled by a separate tool called createrepo, which generates the necessary XML metadata. If you have a slow internet connection or collection of all downloaded ISO images, use this hack to install rpms from iso images.

Step # 1: Mount an ISO file

Type the following command (replace iso file name with the actual iso file): 

  yum install createrepo
  mkdir -p /mnt/dvd
  mount -o loop /dev/sr0/ /mnt/dvd
  mkdir -p /var/ftp/pub/fedora-20-dvd
  cp /mnt/dvd/*  /var/ftp/pub/fedora-20-dvd/ -a

Step # 2: Create config file

Create a repo config file in **/etc/yum.repos.d/local.repo.

Its content is as below: 

[local-repo]
name='local repo based on Fedora 20 DVD ISO'
baseurl=file:///var/ftp/pub/fedora-20-dvd
enabled=1
gpgcheck=0

Test

#yum repolist all

Its print log is like below:
