Q:

rails nginx unicorn listen multiple port

First, sorry for my English (T^T)
I want to run three apps.
(actually, one app. only Difference is environment (development, staging, production))
so I modify some conf codes.
but only working on 80 port!
If I change port of server on working (listening 80) to 81, it not works on port 81 T^T.
I dont know why it is only working on 80 port
Here is my my_app_nginx.conf, deploy.rb, unicorn.rb, unicorn_init.sh, 'netstat -lnp'
/etc/nginx/sites-enabled/my_app_nginx (it is included nginx.conf) 
Three upstrem.
and three server on listening port 80(production), 3000(development), 3001(staging)

                   '"$request" $status $body_bytes_sent '
                   '"$http_referer" "$http_user_agent" "$gzip_ratio"';

I tried to "nginx restart" and sh -c "/etc/init.d/unicorn_chimiseng_ENVIRONMENT restart ENVIRONMENT" not working. 
But you can see netstat -lnp.. listen ports well and the socks is active. 
And there is no default deferred options at nginx 'listen' 
Why cannot use ports except for 80 ??
please help me T^T

A:

Sorry T^T
I resolved this problem.
I'm using a cloud server.
All of a sudden, thinking about Fort forwarding in cloud server web site strike me. 
Allow for 3000, 3001 port in the web site.. it works well...!
Every body click down unclear question.. sorry for reading this question. X(
Have a nice day!
