How to use root?

[kokofixcomputers]

How do i use root instead of proxy forwarding? In my case, i want to run pterodactyl. This is a normal nginx example:

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name panel.example.com;

    root /var/www/pterodactyl/public;  # Path to your Pterodactyl installation
    index index.php index.html index.htm;

    charset utf-8;

    access_log /var/log/nginx/pterodactyl.app-access.log;
    error_log /var/log/nginx/pterodactyl.app-error.log error;

    # Allow larger file uploads and longer script runtimes
    client_max_body_size 100m;
    client_body_timeout 120s;

    sendfile off;

    location / {
        try_files $uri $uri/ /index.php?$query_string;  # Handle requests
    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt { access_log off; log_not_found off; }

    # PHP-FPM Configuration
    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/run/php/php8.1-fpm.sock;  # Adjust PHP version if necessary
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_param HTTP_PROXY "";  # Prevent proxy header issues
        fastcgi_intercept_errors off;
        fastcgi_buffer_size 16k;
        fastcgi_buffers 4 16k;
        fastcgi_connect_timeout 300;
        fastcgi_send_timeout 300;
        fastcgi_read_timeout 300;
        fastcgi_param PHP_VALUE "upload_max_filesize = 100M \n post_max_size=100M";  # Increase upload limits
    }

    location ~ /\.ht {
        deny all;  # Deny access to .htaccess files
    }
