Nginx Primary script unknown (fastcgi_param + alias)

Question

I'm using Laravel in a serverblock and I'd like to create an alias, for example /webmail. This results in an nginx "Primary script unknown" error. I think I need to change my fastcgi_param. Can anyone help me?

Below is the important part about my Nginx serverblock.

server {

    listen       80 default_server;
    server_name  _;

    set $root_path '/var/www/html/public';
    root $root_path;

    index index.php index.html index.htm;

    try_files $uri $uri/ @rewrite;

    location @rewrite {
        rewrite ^/(.*)$ /index.php?_url=/$1;
    }

    location ~ \.php {

        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index /index.php;

        include /etc/nginx/fastcgi_params;

        fastcgi_split_path_info       ^(.+\.php)(/.+)$;
        fastcgi_param PATH_INFO       $fastcgi_path_info;
        fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    location /webmail {
        root /var/www/;
    }
}

So my webmail application is located in /var/www/webmail.

Webmail works when I change the SCRIPT_FILENAME to:

fastcgi_param SCRIPT_FILENAME /var/www$fastcgi_script_name;

However, the root domain doesn't work anymore after this change. I can't place the line above in the location section.

Try this configuration:

server {

    listen       80 default_server;
    server_name  _;

    set $root_path '/var/www/html/public';
    root $root_path;

    index index.php index.html index.htm;

    try_files $uri $uri/ @rewrite;

    location @rewrite {
        rewrite ^/(.*)$ /index.php?_url=/$1;
    }

    location ~ \.php {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index /index.php;

        include /etc/nginx/fastcgi_params;

        fastcgi_split_path_info       ^(.+\.php)(/.+)$;
        fastcgi_param PATH_INFO       $fastcgi_path_info;
        fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
        fastcgi_param SCRIPT_FILENAME $root_path$fastcgi_script_name;
        fastcgi_param DOCUMENT_ROOT   $root_path;
    }

    location /webmail {
        set $root_path '/var/www';
        root $root_path;
    }
}

So, we pass a different document root / script filename prefix to PHP depending on the location. On default locations we have $root_path set to /var/www/html/public and on /webmail we set it to /var/www.

You may need to add a separate rewrite / try_files section in the /webmail location, so that index.php or any other default webmail entry script is tried. You need to look at your webmail's documentation for this.

I'm currently testing it with Laravel in my subdirectory, but this still returns the same message. Any suggestions?` — Patrick, Aug 15 '16 at 08:59
