Nginx - location with root in other directory and PHP

Running two PHP applications side-by-side, you either need a common document root, or you need two location ~* \.php (or similar) blocks to ensure the correct SCRIPT_FILENAME is sent to the fastcgi backend.

Use nested location blocks to isolate the /cut subdirectory, and use the ^~ modifier at the top level to avoid other top level regular expression location blocks from interfering (see this documentation).

The alias directive (see this documentation) is used to map /cut to /var/www/cut/public. The root directive can only concatenate, which would make /var/www/cut/public/cut (which you do not want).

However, I would not recommend using the alias directive with the try_files directive because of this long term issue.

So, a solution would be to silently rewrite /cut to /cut/public and use a value of root /var/www.

For example:

location ^~ /cut {    rewrite ^/cut(.*)$ /cut/public$1 last;}location ^~ /cut/public {    root /var/www;    try_files $uri $uri/ /cut/index.php$is_args$args;    location ~* \.php(/|$) {        fastcgi_pass  php:9000;        fastcgi_split_path_info ^(.+\.php)(/.*)$;        include fastcgi_params;        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;    }}
