All websites in the UTN infrastructure are hosted using NGINX. NGINX is a efficient web server that can host many websites efficiently and has options to support almost any need a web server might have.
Most UTN deployments are done using Ansible and that the NGINX configurations for those applications is located within the Ansible repository.
All configurations for the websites that NGINX serves are available on the server in the /etc/nginx/sites-available folder. In general we try to give each file the name of the website(FQDN) that it serves. To enable on of the websites we can simply symlink the configuration file to /etc/nginx/sites-available (e.g., ln -s /etc/nginx/sites-available/test.utn.se /etc/nginx/sites-enabled/test.utn.se).
The commands you should keep in mind when working with NGINX are the following:
nginx -t, to test if the configurations are valid. (This will avoid blank
pages for users.)systemctl reload nginx, to start using the configurations currently enabled.systemctl restart nginx, to restart the whole web server.These commands need to be run as the root user.
