Nginx – Redirect Non-WWW to WWW Over SSL with Nginx

httpsnginxsslssl-certificate

I'm having an error when trying to redirect https://example.com to https://www.example.com.

When I go to https://example.com, it doesn't redirect and returns the page/200 status.

I don't want this, I want it to redirect to https://www.example.com.

When I go to http://example.com, it redirects to https://www.example.com

Can somebody tell me where I am going wrong?

This is my default and default-ssl configuration files:

default.conf

server {
    listen 80;
    server_name example.com;
    return 301 https://www.example.com$request_uri;
}

default-ssl.conf

upstream app_server_ssl {
    server unix:/tmp/unicorn.sock fail_timeout=0;
}

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

    listen 443;
    root /home/app/myproject/current/public;
    index index.html index.htm;

    error_log /srv/www/example.com/logs/error.log info;
    access_log /srv/www/example.com/logs/access.log combined;

    ssl on;
    ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
    ssl_certificate /srv/www/example.com/keys/ssl.crt;
    ssl_certificate_key /srv/www/example.com/keys/www.example.com.key;
    ssl_ciphers AES128-SHA:RC4-MD5:ECDH+AESGCM:ECDH+AES256:ECDH+AES128:DH+3DES:RSA+3DES:!ADH:!AECDH:!MD5:AES128-SHA;
    ssl_prefer_server_ciphers on;

    client_max_body_size 20M;


    try_files $uri/index.html $uri.html $uri @app;


    # CVE-2013-2028 http://mailman.nginx.org/pipermail/nginx-announce/2013/000112.html
    if ($http_transfer_encoding ~* chunked) {
            return 444;
        }

    location @app {
        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_ssl;
    }

    error_page 500 502 503 504 /500.html;

    location = /500.html {
        root /home/app/example/current/public;
    }
}

Best Answer

You are missing listen directive in file default-ssl.conf. Add listen 443; in this directive

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

By default, if you omit this directive, nginx assume that you want listen on port 80. Here the documentation of this default behavior.

Edit: Thanks for comment from @TeroKilkanen.

Here the complete config for your default-ssl.conf

server {
    listen 443 ssl;
    server_name example.com;

    ssl_certificate /srv/www/example.com/keys/ssl.crt;
    ssl_certificate_key /srv/www/example.com/keys/www.example.com.key;
    return 301 https://www.example.com$request_uri;
}

Sidenote: You can replace ssl on; directive with listen 443 ssl; as recommendation from nginx documentation.
