Sites Enabled

Symlink to ../sites-available/ for any site you want to enable. Conversely, remove the symlink in this folder to disable a site without permanently deleting the site's configuration.

E.g. (we suppose your nginx configuration files are stored in /etc/nginx)

    $ pwd
      --> /etc/nginx
    # ln -s /etc/nginx/sites-available/example.com sites-enabled/example.com
