Gerrit on Amazon EC2

[Wei Dai]

Hello,

     I'm trying to set up a code review system Gerrit on an AWS EC2 instance for my research project, but can't get the website to work. I followed the installation guide and got the web server running, but couldn't connect to it through my browser. Does anyone have experience in this? Also, if you know of other good code review alternatives that's free, I'd like to give it a thought too. Thank you!  

More technical details: I'm using amazon's Elastic IP and has allow inbound traffic through port 8080 (the apache2 server works). I've also configured the canonicalWebURL in gerrit to be <elastic ip>:8080/

Thanks,

Dai Wei

Gerrit should output some logs when it starts up saying what port it is listening on, so you can check your configuration. Also, can you access Gerrit from localhost (i.e. logged into the EC2 instance)?

And the server is indeed started:

Hi Dave,

    Yeah I checked the logs/error_log, and all seems well:

This is log from an instance on Google Compute Engine (GCE). The log on Amazon EC2 is essentially the same. On both Amazon EC2 and GCE there's an internal IP and external IP. I set canonicalWebUrl to the external IP, and I can ping to that (external) IP from within the instance, but not from the internet. I've asked other Googlers in my office and no one seem to have a clue (one of them apparently had this problem before and couldn't resolve it). So I'd really appreciate any help here.

If anyone feel up to this, I can prepare an instance on EC2 to showcase the problem and let you log in to play with. 

Thank you in advance!
