Nice tutorial. It was very straight forward to follow and I got my twiki running on EC2 (and managed to setup Elastic IP on it!) I had some issue setting up security group though.. mainly because I didn't know that I can't change the security group name once I create my instance. Can you explain how much Amazon will charge to run TWiki on EC2?

I am glad it worked out for you Soichi-san. I do not know the monthly cost, but I think you can estimate using the EC2 cost calculator, http://calculator.s3.amazonaws.com/calc5.html. Are you a developer? I invite you to get involved with our community.

You likely need more disk space, the default is about 1 GB - too small for most deployments.

If you run TWiki on EC2 you need to plan for backup. The cheapest way is to use Amazon S3 storage. Some instructions:

Thanks for the excellent instructions! Just got my instance up and running. Note that I also needed to install the perl Data::Dumper and HTML::Entities packages. You may also want to more explicitly call out the apache restart at the end of step 8 (I missed it the first time and had to go back).

Thanks again!

Thank you Michael. I fixed the doc accordingly.

`chkconfig` only works for systems that use systemVinit. For systems that use systemd, you need `systemctl`.

So:
# /sbin/chkconfig httpd on
becomes
# systemctl enable httpd

and
# /sbin/chkconfig --list httpd
becomes
# systemctl list-unit-files | grep httpd

see the following link for SysVinit to Systemd Cheatsheet

Thank you Arjun. I updated the article accordingly.
