Nginx Configuration Example
---------------------------

Use the following example to configure Nginx as a your web server.


.. code-block:: nginx

    ## rate limiter for certain pages to prevent brute force attacks
    limit_req_zone  $binary_remote_addr  zone=dl_limit:10m   rate=1r/s;

    ## custom log format
    log_format log_custom '$remote_addr - $remote_user [$time_local] '
                          '"$request" $status $body_bytes_sent '
                          '"$http_referer" "$http_user_agent" '
                          '$request_time $upstream_response_time $pipe';

    ## define upstream (local RhodeCode instance) to connect to
    upstream rc {
        # Url to running RhodeCode instance.
        # This is shown as `- URL:` in output from rccontrol status.
        server 127.0.0.1:10002;

        # add more instances for load balancing
        # server 127.0.0.1:10003;
        # server 127.0.0.1:10004;
    }

    ## HTTP to HTTPS rewrite
    server {
        listen          80;
        server_name     rhodecode.myserver.com;

        if ($http_host = rhodecode.myserver.com) {
            rewrite  (.*)  https://rhodecode.myserver.com$1 permanent;
        }
    }

    ## Optional gist alias server, for serving nicer GIST urls.
