How to safely remove www pool and default site from nginx

As you know when you install nginx, it comes with default pool called www and a default site called default.

How can I safely remove these two? Because I have created a new pool and site and I want to release some resources by deleting these.

Solution 1:

Your file locations and service names might be a bit different, but you just need to delete the two configs and reload:

1. Delete the pool configuration file /etc/php/7.0/fpm/pool.d/www.conf
2. Delete the default site configuration file /etc/nginx/sites-available/default and its symlink /etc/nginx/sites-enabled/default
3. Reload nginx sudo service nginx reload
4. Reload fpm sudo service php7.0-fpm reload
