Start mongrel in ssh session and then exit in Ubuntu 10.04

Hi all,

I'm deploying a Rails application in a Ubuntu 10.04 server with mongrel web server. I connect to server and do stuffs in a ssh client (PuTTY). And I'm getting stuck with a strange issue: 1. After I connected to server, I start mongrel with : $ start-stop- daemon -S -d . -x script/server -b -- -p 8080 2. I left the ssh console and launch firefox from my Win7 box and open the website, it runs well. I can see the homepage 3. I go back to the ssh console. Close the terminal (and window too) it by : $ exit 4. Then in firefox, I press F5 to refresh and nothing shows up. It's just an empty space in whole webpage. I tried to use addon to capture the HTTP data and see that the server returns nothing , even HTTP headers

I thought that using start-stop-daemon command could help me run mongrel as daemon and then I can exit my session just as apache does. But it doesn't work.

Do I miss something ?

Updated the message with two more steps

5. I connect to server again, run "ps -Af" to check and see that the process's still running. And again, leave the console, switch to firefox and refresh -> the homepage shows everything. 6. But if I exit the ssh session and refresh browser, the web server returns nothing again

Possible workaround, ssh into server, at shell type "screen", hit space bar, start server, type control-A control-D to detach from screen, logout of SSH session. Later you can log in and type "screen -r" to resume the screen session.

I also find this very useful for long operations on remote systems that might lose the connection (e.g. dialup and wifi).
