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/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] baseurl=file:///mnt/iso enabled=1
Save and close the changes.
Now use yum command to install packages from ISO images:
Test
yum repolist all
# yum install package-name
