Ok good. 
Funny how Apache has to be installed for Apache to work and it helps to use the configured port
I’ll leave it to you to research changing to port 8088. But worry about that later.
So what is called the docroot is where you put the files for your site. Typically the docroot is /var/www/html. That’s where you want to put the Allmon files.
Also, you’re going to need to install more software:
apt-get install php7.0 php7.0-cli php7.0-common libapache2-mod-php7.0
and restart your node.
