502 Bad Gateway error using Nginx/Passenger on OSX (10.6.1)

Hi there.

After several hours of battling with this anomaly, I've finally admitted
defeat. If anyone here can help me I would be most grateful!

***********************************************************************
QUICK SUMMARY:

I have this error in my Nginx error log:

2009/11/09 02:49:59 [error] 90#0: *7 connect() to
unix:/tmp/passenger.54/master/helper_server.sock failed (61: Connection
refused) while connecting to upstream, client: 127.0.0.1, server:
test.local, request: "GET / HTTP/1.1", upstream:
"passenger://unix:/tmp/passenger.54/master/helper_server.sock:", host:
"test.local"

The full details are below.

***********************************************************************

I've installed Nginx and Passenger on my local machine with a view to
using it for local development. I was running Apache and Passenger but I
was getting a few bugs so I decided to switch.

I installed the Passenger Nginx extension without any trouble into
/usr/local/nginx

and configured Nginx in /usr/local/nginx/conf/nginx.conf

For completeness here is the contents of nginx.conf:

worker_processes 2;
pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
passenger_root /usr/local/lib/ruby/gems/1.8/gems/passenger-2.2.5;
passenger_ruby /usr/local/bin/ruby;
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name test.local;
root /Users/i0n/Sites/test/public;
passenger_enabled on;
rails_env development;
client_max_body_size 10M;
client_body_buffer_size 128k;
}
}

I then added /usr/local/nginx/sbin to my path variable.
So far so good. If I start up Nginx from the terminal using sudo nginx I
get no trouble whatsoever, I can view my test Rails app at
http://test.local as expected.

The problem arrises when I try and configure the system to load Nginx on
startup. I have followed the instructions from the Nginx wiki (with some
adjustments for differing paths)

I have created a plist file in:
/System/Library/LaunchDaemons/nginx.plist

It's contents look like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key><string>nginx</string>
<key>Program</key><string>/usr/local/nginx/sbin/nginx</string>
<key>KeepAlive</key><true/>
<key>NetworkState</key><true/>
<key>StandardErrorPath</key><string>/usr/local/nginx/logs/error.log</string>
<key>LaunchOnlyOnce</key><true/>
</dict>
</plist>

I then run sudo launchctl load -F
/System/Library/LaunchDaemons/nginx.plist

If I reboot the system and go to http://test.local in the browser I see
a page that says:

502 Bad Gateway
nginx/0.7.61

If I look in the Nginx error log (which is at
/usr/local/nginx/logs/error.log)

I see the following error recorded:

2009/11/09 02:49:59 [error] 90#0: *7 connect() to
unix:/tmp/passenger.54/master/helper_server.sock failed (61: Connection
refused) while connecting to upstream, client: 127.0.0.1, server:
test.local, request: "GET / HTTP/1.1", upstream:
"passenger://unix:/tmp/passenger.54/master/helper_server.sock:", host:
"test.local"

If I manually stop and then start Nginx from the terminal using sudo it
begins to work. To be honest this one has me stumped, it's probably
something really simple but I just can't see it at the moment. Any
thoughts or suggestions would be gratefully received. Thanks for taking
the time to read this!

Ian
