Virtual Domains (Apache) on Debian Jessie

Background

This is a multi-step guide for setting up multiple virtual domains using an Apache web server on Debian Jessie distribution.

I've used Debian for as long as I can remember and it's the distribution I recommend for any level of Linux expertise (personally, I use the Stable version on servers and the Testing version for daily use). Additionally, I use Vultr to host my Virtual Private Servers (highly recommended).

The commands in this guide are intended to be clear and mostly usable in a "copy and paste" style. However, this is not meant to be a beginner's guide, so I expect anyone using it to have a clear understanding of what they're doing.

Packages

sudo apt update
sudo apt dist-upgrade
sudo apt install bash-completion apache2 php5 ssl-cert

Prepare Different Directories for Each Virtual Domain

sudo mkdir -p /var/www/{domain00.com,domain01.com,domain02.com}/public_html
sudo chown -R www-data:www-data /var/www/*/public_html

Virtual Domain Configuration

cd /etc/apache2/sites-available/
sudo cp 000-default.conf domain00.com.conf
sudo vi domain00.com.conf

<VirtualHost *:80> 
       ServerName domain00.com
       ServerAlias www.domain00.com
       ServerAdmin webmaster@domain00.com
       DocumentRoot /var/www/domain00.com/public_html 
       ErrorLog ${APACHE_LOG_DIR}/domain00.com-error.log 
       CustomLog ${APACHE_LOG_DIR}/domain00.com-access.log combined 
</VirtualHost>

$ sudo cp domain00.com.conf domain01.com.conf
$ sudo cp domain00.com.conf domain02.com.conf

Note that you'll need to edit the domain01.com.conf and domain02.com.conf files with their respective content, using the domain00.com.conf file as a template.

$ sudo a2dissite 000-default.conf
$ sudo a2ensite domain0{0,1,2}.com.conf

Restart and Testing

sudo systemctl restart apache2.service
