I have a new ubuntu server that I would like to use as a fileserver and intranet webserver, plus I am using Mint 17.2 for the workstation. I am familiar with the webmin and have some terminal skills. What is the best way to create the mount to do this? Should I mount the /var/www/html directory for website development and the /home drive separately? Or would it be easier to simply mount /? I am the only 1 using this network.

What are really trying to do?
What is the end goal?

I want to use my server to store data and move my websites from my workstation to the server. It will never have it's own outside ip. I am trying to simulate a simple network.

You should spend some time learning at http://www.linuxhomenetworking.com/

There is a lot there, I did not see that one but am checking it out. Thank you.

For the file server portion, I would recommend just using Samba. On your server, partition your primary mount point ( / ) and your /home partitions separately (this allows you to do future upgrades as new installs, just not formatting the /home partition and simply migrating the data over to the new user accounts). You might want to have a separate mount point for your files that the server will serve up to the network. You can create sub-directories on that mount point that use different permissions in order to prevent guests from over-writing data, etc.

For the Apache web server,... here's a nice explanation from Stack Overflow.
