All websites in the UTN infrastructure are hosted using NGINX, an efficient web server capable of hosting multiple websites and offering a wide range of server needs.

NGINX configurations for the hosted websites are stored on the server in the /etc/nginx/sites-available directory. Typically, each configuration file is named after the website (FQDN) it serves. To activate a website, create a symlink from the configuration file to /etc/nginx/sites-enabled. For example: ln -s /etc/nginx/sites-available/test.utn.se /etc/nginx/sites-enabled/test.utn.se.

Useful Commands #

Here are some important commands to use when working with NGINX:

• nginx -t: Tests the NGINX configuration files for correctness, preventing downtime or blank pages for users.
• systemctl reload nginx: Applies changes by reloading the NGINX configurations without restarting the service.
• systemctl restart nginx: Fully restarts the NGINX service, applying changes and restarting all worker processes.
