I have recently set up a VPS and am trying to deploy a rails app. I watched a screencast: http://railscasts.com/episodes/335-deploying-to-a-vps which explained how to setup capistrano and unicorn with nginx, but also gave examples for apache.
I followed online guide for setting up passenger and adapted the railscasts capistrano recipe. When I run cap deploy:setup some directories are created on my server in the root of the application. Then when I run cap deploy the rails app is put into the releases folder and in a directory named by timestamp. So that part seems to work just fine.
So then for a while when i navigated to http://dev.gregchapple.com/site/index I got some passenger errors saying that certain gems were missing, so I installed them on the server using bundler then the errors went away. Thats when the current problem arose. Now when I go to http://dev.gregchapple.com/site/index all it says is: "We’re sorry, but something went wrong."
The apache log contains this:
cache: [GET /site/index] miss
cache: [GET /] miss
Does anyone know what the problem is?
My apache config file has been altered to set the document root to the public directory as specified by the passenger docs. I dont know what the problem is and its driving me insane!
Any help is greatly appreciated 🙂
UPDATE
This is what appears the production.log file:
Started GET "/site/index" for 109.255.221.170 at 2012-08-06 13:26:13 -0700

I had similar problem like you. I changed these rows in database.yml
add
remove
Then:
You must update everything in code with capistrano, DON’T CHANGE CODE ON VPN (you can create only tmp dir).
You check your sql connection manualy with ssh on vpn. For example
Your virtual host is ok?
