Nginx Subdirectory Root with PHP

Nginx subdirectory root with PHP

If your files are in /etc/nginx/www you will need to use an alias directive, rather than a root directive. See this document for details.

For example:

location ^~ /web {
    index index.php index.html;
    alias /etc/nginx/www;

    if (!-e $request_filename) { rewrite ^ /web/index.php last; }

    location ~ \.php$ {
        if (!-f $request_filename) { return 404; }

        fastcgi_pass php:9000;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $request_filename;
    }
}

Use $request_filename to obtain the correct path to the aliased file. Avoid try_files with alias due to this issue. See this caution on the use of if.

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;
    }
}

Nginx location configuration (subfolders)

To access a path like /var/www/mysite/manage/public with a URI like /manage, you will need to use alias rather than root. See this document for details.

I am assuming that you need to run PHP from both roots, in which case you will need two location ~ \.php blocks, see example below. If you have no PHP within /var/www/mysite/static, you can delete the unused location block.

For example:

server {
    listen 80;
    server_name  example.org;
    error_log /usr/local/etc/nginx/logs/mysite/error.log;
    access_log /usr/local/etc/nginx/logs/mysite/access.log;

    root /var/www/mysite/static;
    index index.html;

    location / {
    }
    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass 127.0.0.1:9000;

        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $request_filename;
        fastcgi_param SCRIPT_NAME $fastcgi_script_name;
    }

    location ^~ /manage {
        alias /var/www/mysite/manage/public;
        index index.php;

        if (!-e $request_filename) { rewrite ^ /manage/index.php last; }

        location ~ \.php$ {
            if (!-f $request_filename) { return 404; }
            fastcgi_pass 127.0.0.1:9000;

            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $request_filename;
            fastcgi_param SCRIPT_NAME $fastcgi_script_name;
        }
    }
}

The ^~ modifier causes the prefix location to take precedence over regular expression locations at the same level. See this document for details.

The alias and try_files directives are not together due to this long standing bug.

Be aware of this caution in the use of the if directive.

nginx: how to serve file from a subfolder of root?

Fixed adding

location /fonts {
   root /var/www/prod.revisions;
}

Nginx with php in one subdirectory

It's likely that your fastcgi_param should be /www$fastcgi_script_name because the variable is the full URI request. Source.
