Installing CentOS 5 requires 8 CDs of iso so if you want a minimal install only, here’s an FAQ excerpt:
Can I install CentOS 5 with just the first CD?
You can do a minimal install that just requires the first CD by performing the following two steps during the installation:
- During the category/task selection, deselect all package categories, and choose the “Customize now” option at the bottom of screen.
- During the customized package selection, deselect everything ( including the Base group ).

- If you use some software raid options (this will also require CD 2 and 5)
- If you use encrypted filesystems
When the anaconda installer notes that additional disks will be required but you desire a one CD install, the quick answer is one or more of the following approaches:
- Trim back and do a minimal install. Then once the install is up and running, pull in more packages with yum and add more options later.
If you want to avoid using more than one CD but want to install more than just the minimal set of packages, you could also consider doing a network installation. A network installation ISO (called boot.iso) is available from the 5/os/<arch>/images/ directory on CentOS mirrors.
