# Webserver Configuration

WARNING

When using the SSL configuration you MUST create SSL certificates, otherwise your webserver will fail to start. See the Creating SSL Certificates documentation page to learn how to create these certificates before continuing.

TIP

If you are using Caddy With Automatic SSL, you do not have to create SSL certificates manually, Caddy will take care of it automatically.

First, remove the default NGINX configuration.

rm /etc/nginx/sites-enabled/default

Now, you should paste the contents of the file below, replacing <domain> with your domain name being used in a file called pterodactyl.conf and place the file in /etc/nginx/sites-available/, or — if on RHEL, Rocky Linux, or AlmaLinux, /etc/nginx/conf.d/.

server {
    # Replace the example <domain> with your domain name or IP address
    listen 80;
    server_name <domain>;
    return 301 https://$server_name$request_uri;
}

server {
    # Replace the example <domain> with your domain name or IP address
    listen 443 ssl http2;
    server_name <domain>;

    root /var/www/pterodactyl/public;
    index index.php;

    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;

# Enabling Configuration

The final step is to enable your NGINX configuration and restart it.

# You do not need to symlink this file if you are using RHEL, Rocky Linux, or AlmaLinux.
sudo ln -s /etc/nginx/sites-available/pterodactyl.conf /etc/nginx/sites-enabled/pterodactyl.conf

# You need to restart nginx regardless of OS.
sudo systemctl restart nginx
