I need to serve my app through my app server at 8080 , and my static files from a directory without touching the app server. # app server on port 8080
    # nginx listens on port 8123
    server {
            listen          8123;
            access_log      off;

            location /static/ {
                    # root /var/www/app/static/;
                    alias /var/www/app/static/;
                    autoindex off;
            }


            location / {
                    proxy_pass              http://127.0.0.1:8080;
                    proxy_set_header        Host             $host;
                    proxy_set_header        X-Real-IP        $remote_addr;
                    proxy_set_header        X-Forwarded-For  $proxy_add_x_forwarded_for;
            }
    }   Now, with this config, everything is working fine. Note that the root directive is commented out. If I activate root and deactivate the alias , it stops working. However, when I remove the trailing /static/ from root , it starts working again. Can someone explain what's going on?

This difference exists in the way the path specified in the root or the alias is processed. root  the location part is appended to root part final path = root + location   alias  the location part is replaced by the alias part final path = alias   To illustrate: Let's say we have the config location /static/ {
    root /var/www/app/static/;
    autoindex off;
}   In this case the final path that Nginx will derive will be /var/www/app/static/static   This is going to return 404 since there is no static/ within static/  This is because the location part is appended to the path specified in the root . Hence, with root , the correct way is location /static/ {
    root /var/www/app/;
    autoindex off;
}   On the other hand, with alias , the location part gets dropped . So for the config location /static/ {
    alias /var/www/app/static/;
    autoindex off;           ↑
}                            |
                             pay attention to this trailing slash   the final path will correctly be formed as /var/www/app/static   In a way this makes sense. The alias just lets you define a new path to represent an existing "real" path. The location part is that new path, and so it gets replaced with the real path. Think of it as a symlink. Root, on the other hand is not a new path, it contains some information that has to be collated with some other info to make the final path. And so, the location part is used, not dropped. The case for trailing slash in alias   There is no definitive guideline about whether a trailing slash is mandatory per (https://nginx.org/en/docs/http/ngx_http_core_module.html#alias) Nginx documentation , but a common observation by people here and elsewhere seems to indicate that it is. A few more places have discussed this, not conclusively though.

In your case, you can use root directive, because $uri part of the location directive is the same with last root directive part. (http://nginx.org/en/docs/http/ngx_http_core_module.html#alias) Nginx documentation advices it as well:When location matches the last part of the directive’s value: location /images/ {
    alias /data/w3/images/;
}   it is better to use the root directive instead: location /images/ {
    root /data/w3;
}    and root directive will append $uri to the path.

Just a quick addendum to @good_computer's very helpful answer, I wanted to replace to root of the URL with a folder, but only if it matched a subfolder containing static files (which I wanted to retain as part of the path). For example if file requested is in /app/js or /app/css , look in /app/location/public/[that folder] .  I got this to work using a regex. location ~ ^/app/((images/|stylesheets/|javascripts/).*)$ {
     alias /home/user/sites/app/public/$1;

Though my answer is not needed, But I think It is necessary to add this, root and alias works differently when is come to regex. location ~ /static/my.png$ {
     alias /var/www/static/;
     access_log off;
     expires max;
 }   In this case the regex match is not going to add with alias, nginx will search only /var/www/static/ not /var/www/static/my.png . You have to use regex capture. location ~ /static/my.png$ {
     root /var/www;
