How is it possible for an Apache web server to not have any entries in its /etc/apache/sites-enabled directory but still serve websites?
I am running an Apache web server on Ubuntu 14.04.2 LTS. I have more than 20 websites responding correctly on this server.
Recently I decided to implement a Drupal multisite and that took me to /etc/apache/sites-available to edit the 000-default.conf. It is the only .conf file available and has the following content:
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
This handles serving for all the websites on my server but in attempting to debug why a second .conf file does not work, I altered the DocumentRoot to /var/www2, a directory which does not exist.
Once I had saved the document and restarted Apache, I found my websites still loading successfully.
I disabled the 000-default.conf virtualhost, expecting that my websites would stop loading, but they still worked.
Just to be certain, I stopped Apache and all my websites stopped responding, but right now all my websites are responding from an Apache server which has no entries in the sites-enabled directory?
Appreciating that getting things to STOP working is the very opposite of what forums are for, I am trying to understand why my websites are still loading even with all virtualhosts disabled so I can begin solving other problems.
