[OPEN-ILS-GENERAL] Server Requirements for Demo

[Justin Hopkins]

I've been using that image on EC2 recently, so I thought I'd add what I've learned so far:

* A 'small' instance is just barely enough to run it. It's *very* slow.
* opensrf services do not start up well. I need to log in each time I start the instance and run osrf_ctl.sh -l  -a stop_all/ osrf_ctl.sh -l -a start_all
* Since it's Ubuntu, root user login via ssh is turned off by default. You'll need to login as 'ubuntu' and then sudo su - opensrf
* By default, access will be blocked by the security settings on your EC2 instance. You'll want to create a new security group before you create your instance that allows port 22, 80, and 443 then create your instance with that security group.

I haven't tried launching a larger instance with this image, but I suspect it would be worth doing.

Edit: I am booting up a larger instance right now. I appreciate your work on this Brian - it's obviously a very helpful tool for quickly deploying a test environment.

Cheers,
Justin

The entire Evergreen server can run in a 1GB virtual image.  It can also be spread out across multiple servers, with different requirements for different components.  It requires some flavor of Linnus, though may possibly run on other POSIX systems.
