Nginx deployment gives a warning

Rails Deployment

Hi,
I have deployed my rails application using nginx module.
It is running successfully but my problem is whenever I am restart/start
the server I am getting following warning
“[warn]: conflicting server name “localhost” on 0.0.0.0:3000, ignored”

My nginx.conf file is as follows:-

#user nobody;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;

events {
worker_connections 1024;
}

http {
passenger_root /usr/local/lib/ruby/gems/1.8/gems/passenger-2.2.15;
passenger_ruby /usr/local/bin/ruby;

include       mime.types;
default_type  application/octet-stream;

#log_format  main  '$remote_addr - $remote_user [$time_local]

“$request” ’
# '$status $body_bytes_sent “$http_referer” ’

}

server {
    listen       3000;
    server_name  localhost;

    #charset koi8-r;

    #access_log  logs/host.access.log  main;

    location / {

        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;

#}

    # deny access to .htaccess files, if Apache's document root

#    location / {
#        root   html;
#        index  index.html index.htm;
#    }
#}

}

Can anyone tell me how to solve this?

Thanks,

Hi,

you can’t have server twice listening on the same port with same name.

your first server {Listen 3000; servername localhost; …} with
passenger
and a second one server Listen 3000; servername localhost;…}

make a backup of the file then remove the second server {} block. The
message should disappear.

Cheers
Alex
