How to serve all existing static files directly with NGINX, but proxy the rest to a backend server.

Question

location / {
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    if (-f $request_filename) {
        access_log off;
        expires 30d;
        break;
        }

    if (!-f $request_filename) {
        proxy_pass http://127.0.0.1:8080; # backend server listening
        break;
        }
    }

Above will serve all existing files directly using Nginx (e.g. Nginx just displays PHP source code), otherwise forward a request to Apache. I need to exclude *.php files from the rule so that requests for *.php are also passed to Apache and processed.

I want Nginx to handle all static files and Apache to process all dynamic stuff.

EDIT: There is white list approach, but it is not very elegant, See all those extensions, I don't want this.

location ~* ^.+.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js)$ {
    access_log off;
    expires 30d;
    }
location / {
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://127.0.0.1:8080;
    }

EDIT 2: On newer versions of Nginx use try_files instead http://wiki.nginx.org/HttpCoreModule#try_files

Answer 1

Use try_files and named location block ('@apachesite'). This will remove unnecessary regex match and if block. More efficient.

location / {
    root /path/to/root/of/static/files;
    try_files $uri $uri/ @apachesite;

    expires max;
    access_log off;
}

location @apachesite {
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://127.0.0.1:8080;
}

Update: The assumption of this config is that there doesn't exist any php script under /path/to/root/of/static/files. This is common in most modern php frameworks. In case your legacy php projects have both php scripts and static files mixed in the same folder, you may have to whitelist all of the file types you want nginx to serve.
