Tiny tips: Mount linux distribution ISO and create local repository for yum
So you have this server that was built a few years ago, and you need to install a couple of rpms for whatever reason. Unfortunately the distro disk has been used as a coaster and cannot fulfill its original role. And then you think – why didn’t I create an ISO image on the local drive.
If you did, however, create an ISO image, it’s now easy to mount it and even create a local repository, so you could yum the packaged instead or rpm-ing them.
First, mount the image, straight forward -
# mkdir -p /media/distro_iso # mount -o loop /path/to/distro.iso /media/distro_iso
Then create the repo -
# mkdir /tmp/local_repo # cd /media/distro_iso # createrepo -o /tmp/local_repo .
This can take some time –
729/3187 - Server/gcc-4.1.2-48.el5.x86_64.rpm ... 735/3187 - Server/gcc-objc-4.1.2-48.el5.x86_64.rpm ... 737/3187 - Server/gcc44-c++-4.4.0-6.el5.x86_64.rpm ...
When it’s finished, register the repo -
## /etc/yum.repos.d/distro_iso.repo [MyLocalRepo] name=summer baseurl=file:///tmp/local_repo enabled=1
Check it –
# yum repolist Loaded plugins: security MyLocalRepo | 951 B 00:00 MyLocalRepo/primary | 817 kB 00:00 MyLocalRepo 3187/3187 repo id repo name status MyLocalRepo summer enabled: 3,187 repolist: 3,187
Looks good, let’s try installing something -
# yum install mc Loaded plugins: security Setting up Install Process Package 1:mc-4.6.1a-35.el5.x86_64 already installed and latest version Nothing to do
