Howto Setup yum repositories to update or install package from ISO CDROM Image
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/iso/{1,2,3}
# mount -o loop /path/to/centos1.iso /mnt/iso/1
Step # 2: Create a repository
Use createrepo to generate the necessary XML metadata. Type the following commands:
# cd /mnt/iso
# createrepo .
Clean repo, enter:
# yum clean all
Step # 3: Create config file
You need to create a repo config file in /etc/yum.repos.d/ directory.
# vi /etc/yum.repos.d/iso.repo
Append following text:
[My ISO Repository]
Save and close the changes.
baseurl=file:///mnt/iso
enabled=1
gpgcheck=1
gpgkey=file:///mnt/iso/1/RPM-GPG-KEY-redhat-release
Now use yum command to install packages from ISO images:
# yum install package-name
