nginx configuration issue, ports already in use - php

Question

I recently migrated to Mac OSX Yosemite 10.10 and I followed this tutorial.
To set up my machine, After a lots of hiccups I finally managed to reach a point where I find just a single issue happening due to nginx port issues.
If I do
sudo nginx
I get this
nginx: [emerg] bind() to 0.0.0.0:443 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:306 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:443 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:306 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:443 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:306 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:443 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:306 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:443 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:306 failed (48: Address already in use)
nginx: [emerg] still could not bind()
which means 443 and 306 ports are being used somewhere else
and when I do
sudo lsof -i:443
I get this
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
nginx 548 root 13u IPv4 0xce9cf564560ec22b 0t0 TCP *:https (LISTEN)
nginx 549 nobody 13u IPv4 0xce9cf564560ec22b 0t0 TCP *:https (LISTEN)
similarly for sudo lsof -i:306
I get
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
nginx 548 root 14u IPv4 0xce9cf564560ed3cb 0t0 TCP *:306 (LISTEN)
nginx 549 nobody 14u IPv4 0xce9cf564560ed3cb 0t0 TCP *:306 (LISTEN)
Now if nginx is already using these ports, how come it is claiming that Address is already in use
and when I run my app in browser say abc.dev.com
I get no response from server, after sometime browser simply tells me
The connection has timed out
The server at abc.dev.com is taking too long to respond.
If i do curl http://abc.dev.com I get
curl: (7) Failed to connect to abc.dev.com port 80: Operation timed out
Also If I do
nginx.start
I get this:
/Library/LaunchDaemons/homebrew.mxcl.nginx.plist: Operation already in progress
if I do::
nginx.stop //it works, I think it stops
if I do:
nginx.restart
I get this:
/Library/LaunchDaemons/homebrew.mxcl.nginx.plist: Could not find specified service
I have ran out of ideas and can't think of anything that could be causing this. Any Ideas are highly appreciated...
Thanks for the help.

Author of the guide you've linked above here. It seems like you managed to get Nginx running without the proper LaunchDaemon.
Can you make sure, when you enter "nginx.stop", the process is really stopped? (ps aux).
Regarding the last error while "nginx.restart": thats normal, because you already stopped the service before with "nginx.stop". So a restart (actually: stop && start) will come up with the error since it's trying to stop an already stopped service.
Anyway, since your issue is pretty much guide-dependent / relevant, I'm not sure if StackOverflow is the right place for this discussion. Let's better continue in the comment section of the guide.
