[CentOS] httpd/sites-available directory

[Robert Moskowitz]

I see I have some things to learn, or just maybe remember about 
virtualhosts:

https://httpd.apache.org/docs/2.4/vhosts/examples.html

"The asterisks match all addresses, so the main server serves no 
requests. Due to the fact that the virtual host with |ServerName 
www.example.com| is first in the configuration file, it has the highest 
priority and can be seen as the default or primary server. That means 
that if a request is received that does not match one of the specified 
|ServerName 
<https://httpd.apache.org/docs/2.4/mod/core.html#servername>| 
directives, it will be served by this first |<VirtualHost> 
<https://httpd.apache.org/docs/2.4/mod/core.html#virtualhost>|."

This means I really should have a 00-init.conf file with:

<VirtualHost *:80>
ServerName foo.bar.com
</virtualHost>


I have not figured out yet if I need some default directory section 
within that.

Also once you have virtualhost, it seems that every directory has to be 
in a virtual host envelope?

thanks
