Forum: NGINX The service is not available. Please try again later.

I'm trying to get a Bitnami Rails running with Nginx and Thin.

I've got Thin servers running on:

bitnami@linux:/opt/bitnami$  thin -C
projects/ndeavor/current/config/thin.yml start

Starting server on 127.0.0.1:3000 ...

Starting server on 127.0.0.1:3001 ...

Starting server on 127.0.0.1:3002 ...

Starting server on 127.0.0.1:3003 ...

Starting server on 127.0.0.1:3004 ...

I've got Nginx running:

bitnami@linux:/opt/bitnami$ sudo ./ctlscript.sh start nginx
/opt/bitnami/nginx/scripts/ctl.sh : Nginx started

And after I start Nginx, then the thin.3000.log has:


    >> Thin web server (v1.5.0 codename Knife)
    >> Maximum connections set to 1024
    >> Listening on 127.0.0.1:3000, CTRL+C to stop

So, I believe that Nginx is connected to the 5 Thin app servers.

I have the nginx.conf listen on port 80

But, when I try to connect using a browser, I get this:

"The service is not available. Please try again later."

It's the same message I get if nginx is not running.

Is something in Ubuntu stopping http port 80 from reaching nginx?

This is my nginx.conf file.  Does it look OK?

I got past that error and now the nginx error log has this:

Is the application listening on those ports?  What does netstat show? 
Can
you telnet to the app server on those ports?  Could the app not be
listening on 127.0.0.1 and only on the non-loopback address?

OK - I now have Nginx running the 5 Thin app servers!

Thanks for the help!
