Install packages from CentOS 5.5 ISO CDROM images

1. Upload CentOS’s ISO files (i have 7 iso files) into /centos5.5_iso_files directory.

2. It is probably that you do not have createrepo rpm package, then download it from CentOS RPM repository.
I’ve found it in

3. Install createrepo-0.4.11-3.el5.noarch.rpm:

# rpm -ihv createrepo-0.4.11-3.el5.noarch.rpm

… and check installation:

# rpm -qa | grep createrepo

4. Mount the 7 ISO files:

# mkdir -p /mnt/iso/{1,2,3,4,5,6,7}
# mount -o loop /root/centos55-i386-isos/CentOS-5.5-i386-bin-1of7.iso /mnt/iso/1
# mount -o loop /root/centos55-i386-isos/CentOS-5.5-i386-bin-2of7.iso /mnt/iso/2
# mount -o loop /root/centos55-i386-isos/CentOS-5.5-i386-bin-3of7.iso /mnt/iso/3
# mount -o loop /root/centos55-i386-isos/CentOS-5.5-i386-bin-4of7.iso /mnt/iso/4
# mount -o loop /root/centos55-i386-isos/CentOS-5.5-i386-bin-5of7.iso /mnt/iso/5
# mount -o loop /root/centos55-i386-isos/CentOS-5.5-i386-bin-6of7.iso /mnt/iso/6
# mount -o loop /root/centos55-i386-isos/CentOS-5.5-i386-bin-7of7.iso /mnt/iso/7

5. Create a new Yum’s repository:

# cd /mnt/iso
# createrepo .
2598/2598 - 4/CentOS/zsh-4.2.6-3.el5.i386.rpm                                   rpmm6.rpm

# yum clean all

6. Create repository configuration file:

# nano /etc/yum.repos.d/centos55_i386_iso.repo



7. Save and close the changes, now you can use Yum to install, search packages from ISO images, for example:

# yum --nogpgcheck install my-package-name
# yum search my-package-name

8. Troubleshooting:

– Sometimes when installing, searching or updating packages, Yum shows errors as “Bad id for repo: ….”, for solve it you could to delete strange chars or blank spaces in /etc/yum.repos.d/centos55_i386_iso.repo

– When yum shows following error:

Could not retrieve mirrorlist error was
[Errno 4] IOError:
Error: Cannot find a valid baseurl for repo: addons

you had to disable repositories in /etc/yum.repos.d/CenOS-Base.repo, make sure of save a backup

append to each section:


then, clean cache again:

# yum clean all
