Dev server setup using the Amazon EC2 AMI

1. Launch an instance using the AMI identifier ami-f56a739c, or by clicking here

• If you're a code.org security group member, you can choose your own public key
• This can run on a micro instance, but it will occasionally be sluggish to load pages. A medium instance runs it comfortably.

2. Edit your EC2 instance's security group to allow access to ports 3000
3. git pull to update your code, and follow the Rails server setup instructions starting at step 6 in the main README
4. If you'd like to run your server as a daemon, start it with bundle exec rails server -d

• You can restart it with:

kill `cat tmp/pids/server.pid`

Custom subdomain

If you'd like to set a custom subdomain for your staging server, you can do that using AWS Route 53.

Go to the Route 53 control panel, double-click a Hosted Zone (e.g., code.org), and click Create Record Set. Fill in the following values:

• Type: CNAME
• Name: your-dev-subdomain.learn.code.org.
• Value: your EC2 subdomain, e.g., ec2-[ip-address].compute-1.amazonaws.com
• All other fields can be left at their defaults
