Nginx Configuration Example

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

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

## cache zone
proxy_cache_path /etc/nginx/nginx_cache levels=1:2 use_temp_path=off keys_zone=cache_zone:10m inactive=720h max_size=10g;

## 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 one or more upstreams (local RhodeCode instance) to connect to
upstream rc {
    # Url to running RhodeCode instance.
    # This is shown as `- URL: <host>` 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.
server {
    listen          443;
    server_name     gist.myserver.com;
    access_log      /var/log/nginx/gist.access.log log_custom;
