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” ’  
# ‘"$http\_user\_agent" “$http\_x\_forwarded\_for”’;

```
#access_log logs/access.log main;

#gzip on;

   listen 3000;
   server_name localhost;

```

sure to point to ‘public’!  
passenger\_enabled on;  
passenger\_use\_global\_queue on;  
}

```
server {
    listen 3000;
    server_name localhost;

    #charset koi8-r;

    #access_log logs/host.access.log main;

    location / {
        root html;
        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;
    #}

    # pass the PHP scripts to FastCGI server listening on

```

127.0.0.1:9000  
#  
#location ~ .php$ {  
# root html;

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

    #}
}

configuration  
#  
#server {

```
# location / {

#server {

# ssl\_prefer\_server\_ciphers on;

```
# 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
