Speed up your Fedora PXE installations by hosting the stage2 installer locally
In my previous post about installing Fedora via PXE, I forgot to mention a big time saver for the installation. A Fedora PXE installation requires a few different things:
- initial ramdisk (
- kernel (
- installation repository
If you only specify an installation repository, then Anaconda tries to drag down a 214MB squashfs.img file in each installation. You can host this file locally by recreating a portion of a Fedora repo’s structure and dropping two files into it.
Do the following in a directory that can be served up via HTTP:
mkdir -p fedora/releases/19/Fedora/x86_64/os/LiveOS/ cd fedora/releases/19/Fedora/x86_64/os/LiveOS/ wget http://mirror.rackspace.com/fedora/releases/19/Fedora/x86_64/os/LiveOS/squashfs.img cd .. wget http://mirror.rackspace.com/fedora/releases/19/Fedora/x86_64/os/.treeinfo
Your files are now ready. Go back to your tftp server and adjust your
label linux menu label Install Fedora 19 guest kernel vmlinuz append initrd=initrd.img inst.stage2=http://localwebserver.example.com/fedora/releases/19/Fedora/x86_64/os/ inst.repo=http://mirror.rackspace.com/fedora/releases/19/Fedora/x86_64/os/ ks=http://example.com/kickstart.ks ip=eth0:dhcp
This should speed up your installations by a large amount (unless your internet connection is much faster than mine).
