[emerg] duplicate upstream "app_server" in /etc/nginx/sites-enabled/<project_name>:1

Posted on January 22, 2015

I’m following this tutorial by @asb. But i got this error when I try restart nginx:

[emerg] duplicate upstream "app_server" in /etc/nginx/sites-enabled/test-django:1

The test-django file in etc/nginx/site-available/ :

upstream app_server {
    server 127.0.0.1:9500 fail_timeout=0;
}

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /usr/share/nginx/html;
    index index.html index.htm;

    client_max_body_size 4G;
    server_name www.mydomain.com;

    keepalive_timeout 5;

    # Your Django project's media files - amend as required
    location /media  {
        alias /home/django/test-django/cmsh/media;
    }

    # your Django project's static files - amend as required
    location /static {
        alias /home/django/test-django/cmsh/static;
    }

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_pass http://app_server;
    }
}

Never mind this fix the error:

cd  /etc/nginx/sites-enabled/

sudo rm -r test-django

sudo service nginx restart

 * Restarting nginx nginx

and my test-django looks like this now:

upstream app_server {
    server 127.0.0.1:9500 fail_timeout=0;
}

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /usr/share/nginx/html;
    index index.html index.htm;

    client_max_body_size 4G;
    server_name www.mydomain.com;

    keepalive_timeout 5;

    # Your Django project's media files - amend as required
    location /media  {
        alias /home/django/test-django/cmsh/media;
    }

    # your Django project's static files - amend as required
    location /static {
        alias /home/django/test-django/cmsh/static;
    }

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_pass http://app_server;
    }
}

‘default_server’ were deleted
