howto: install archlinux on amazon ec2

after having some trouble getting archlinux running on amazon ec2, i want to share my steps of how to get things working.

this is no deepdive tutorial on ec2 in general, nor a "run a server"-guide. i prerequisite you have a amazon ec2, s3 account and a basic understanding of amazon cloud service.

we will bootstrap our archlinux from within a running karmic instance, provided by the ubuntu folks. they ship a recent kernel 2.6.31-302-ec2, amazon still has a 2.6.21 which will have trouble with current udev-versions.

official ubuntu ami and informations can be found here: https://help.ubuntu.com/community/EC2StartersGuide

*** step I - starting a ubuntu instance ***

start up ami-a62a01d2 - (ubuntu 9.10 europe) and login (as user ubuntu) via ssh

*** step II - prepare archlinux chroot ***

# change to root
sudo su
cd /

# mount newarch on existing ubuntu swap partition
mkdir /newarch
swapoff /dev/sda3
mkfs.ext3 /dev/sda3
mount /dev/sda3 /newarch


# download and extract pacman.static
wget http://repo.archlinux.fr/i686/pacman-static-3.2.2-1.pkg.tar.gz
tar xzvf pacman-static-3.2.2-1.pkg.tar.gz

mkdir -p /newarch/var/lib/pacman

cat >/etc/pacman.conf <<\EOF

*** step VI - bundle, upload and register your archlinux instance ***

ec2-bundle-vol \
-v /newarch \
-r i386 \
-d /mnt \
-p ${PREFIX} \
-u ${AMAZON_USER_ID} \
-k ${EC2_PRIVATE_KEY} \
-c ${EC2_CERT} \
-s 10000 \
-e /mnt,/root

ec2-upload-bundle \
-b ${BUCKET} \
-m /mnt/${PREFIX}.manifest.xml \
-a ${AMAZON_ACCESS_KEY_ID} \
-s ${AMAZON_SECRET_ACCESS_KEY}

ec2-register --region eu-west-1 -K ${EC2_PRIVATE_KEY} -C ${EC2_CERT} ${BUCKET}/${PREFIX}.manifest.xml

the last command will print out something like this:

IMAGE   ami-affbd0db

congratulations, this is your very own archlinux ami.

Cool stuff jzimmek - you should consider adding it to the wiki, which is more appropriate for howtos like this.

Re: howto: install archlinux on amazon ec2

Thanks for the excelent tutorial, I've followed (when the instructions still working) it and sucessfully generated my ami, (now that pacman-static doesn't exists its a bit tricky)... now my only problem is that instances aren't booting, the log is also empty... maybe the kernel version isn't compatible or something similar? Any suggestions? Thank you

Re: howto: install archlinux on amazon ec2

Just curious, how much do you end up paying for archlinux ami? Do you think I can convert my free-trial ubuntu ami into Archlinux? That would be great.
Also, are there any archlinux pre-made ami's available?

I run this instance https://aws.amazon.com/amis/archlinux under free tier. No issues of being charged at all.
