How To Redirect www to Non-www with Nginx on Ubuntu 14.04

You should use:

server {
  server_name www.domain.com;
  return 301 $scheme://domain.com$request_uri;
}
server {
  server_name domain.com;
  [...]
}

Otherwise you will get HTTP/1.1 301 Moved Permanently for the www and non-www versions.

Using the code above you’ll get HTTP/1.1 200 OK for the non-www domain. See: http://wiki.nginx.org/Pitfalls#Server_Name

How do I go it on config with SSL ? Should I create 3 server blocks ?

Every form of www to non-www redirects works fine except https://www.example.com. When I run curl -I https://www.example.com I get HTTP/1.1 302 Found and no redirects!

This is really helpful!

Great tutorial!

But doesn’t a simple

do the trick?

It didn’t work for me. I researched and fixed with this way. Open /etc/nginx/sites-available/example . And edit the file like that:

server {
    # SERVER NAME WITH WWW
    server_name www.example.com;

    # LOCATION CONFIGURATIONS
    location = /favicon.ico { ... }
    location /.../ {
        root ...
    }
    location /.../ {
        root ...
    }

    location / {
        ...
    }


    # CERTBOT CONFIGURATIONS FOR SSL
    listen 443 ssl;
    ssl_certificate ... # managed by Certbot
    ssl_certificate_key ... # managed by Certbot
    include ... # managed by Certbot
    ssl_dhparam ... # managed by Certbot

}

server {
    # SERVER NAME WITHOUT WWW
    server_name example.com;

    # CERTBOT CONFIGURATIONS AGAIN
    listen 443 ssl;
    ssl_certificate ... # managed by Certbot
    ssl_certificate_key ... # managed by Certbot
    include ... # managed by Certbot
    ssl_dhparam ... # managed by Certbot

    # REDIRCET TO WWW
    return 301 https://www.example.com$request_uri;

}

I use like:

upstream my_project_server {
  # fail_timeout=0 means we always retry an upstream even if it failed
  # to return a good HTTP response (in case the Unicorn master nukes a
  # single worker for timing out).

  server unix:/webapps/my_project/run/gunicorn.sock fail_timeout=0;
}

server {
  server_name domain.com www.domain.com;

    if ($host = www.domain.com) {
        return 301 $scheme://domain.com$request_uri;
    }

    client_max_body_size 4G;

    access_log /webapps/my_project/logs/nginx-access.log;
    error_log /webapps/my_project/logs/nginx-error.log;
 
    location /static/ {
        alias   /webapps/my_project/static_in_env/static_root/;
    }
    
    location /media/ {
        alias   /webapps/my_project/static_in_env/media_root/;
    }

    location / {
        # an HTTP header important enough to have its own Wikipedia entry:
        #   http://en.wikipedia.org/wiki/X-Forwarded-For
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        # enable this if and only if you use HTTPS, this helps Rack
        # set the proper protocol for doing redirects:
        # proxy_set_header X-Forwarded-Proto https;

        # pass the Host: header from the client right along so redirects
        # can be set properly within the Rack application
        proxy_set_header Host $http_host;

        # we don't want nginx trying to do something clever with
        # redirects, we set the Host: header above already.
        proxy_redirect off;

        # set "proxy_buffering off" *only* for Rainbows! when doing
        # Comet/long-poll stuff.  It's also safe to set if you're
        # using only serving fast clients with Unicorn + nginx.
        # Otherwise you _want_ nginx to buffer responses to slow
        # clients, really.
        # proxy_buffering off;

        # Try to serve static files from nginx, no point in making an
        # *application* server like Unicorn/Rainbows! serve static files.
        if (!-f $request_filename) {
            proxy_pass http://my_project_server;
            break;
        }
    }

Hello, i`m very new to this, could you please tell me how to save after putting:

server {
    server_name www.example.com;
    return 301 $scheme://example.com$request_uri;
}

Thank you

Thanks, it is now working properly for my site.

Hmm, it didn’t work for me. I arrive to the “Welcome to nginx” page when browsing to “myotherdomain.com”
