Forum: NGINX mac os nginx startup launchd configure

I want nginx to be started up every time my Mac os 10.5 system boots up.
So I create a launchd file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Disabled</key>
  <false/>
  <key>Label</key>
  <string>com.zhan.nginx</string>
  <key>OnDemand</key>
  <false/>
  <key>ProgramArguments</key>
  <array>
    <string>/opt/local/sbin/nginx</string>
  </array>
  <key>RunAtLoad</key>
  <true/>
</dict>
</plist>
It works, but inside nginx error log, I see:
2008/08/01 08:24:50 [emerg] 244#0: bind() to 0.0.0.0:80 failed (48:

2008/08/01 08:25:01 [emerg] 257#0: still could not bind()
....
and these errors just go on and on...
If I run the nginx from the terminal, no error shown.
Can anyone tell me what is wrong with my launchd file?

Do you have apache already running on port 80?  Check your "Web
Sharing" in System Preferences.

No, Web Sharing isn't checked, and I don't think any application other 
than nginx is using port 80, because I can visit nginx server from the 
port.

I notice a interesting thing however: whenever I kill the working nginx 
process, a new nginx daemon will be started.
I think it is nginx itself trying to starts a new nginx daemon, even 
when one nginx have been started and have occupied the port.But I don't 
know how two stop the new nginx stop trying.

I am sure I have just one launchd file loaded. Since If I delete or 
unload the one, no working nginx can be found.

Looking in Apache's plist, I see

        <key>ProgramArguments</key>
        <array>
                <string>/usr/sbin/httpd</string>
                <string>-D</string>
                <string>FOREGROUND</string>
        </array>

Probably you need to set "daemon off;" in nginx.conf.

BTW, upgrade to 0.7.8 if you are using case insensitive HFS+,
and do not use UTF-8 strings in locations.

I was having the same problem...  Turning "daemon off;" in nginx.conf 
worked great.   Thanks!
