Build a Linux home server

Alex Campbell reveals how your options range from free to a few hundred pounds

If you’re looking to host your own services instead of paying for or relying on those in the cloud, running your own home server is a great way to keep your fi les private

Ask any Linux enthusiast, and they’ll tell you how fantastic an operating system Linux can be. For the desktop user, the freedom from worry about most viruses is a big plus, and not spending £100 upgrading Windows is a big plus too. As great as Linux is for desktop use, it truly shines as a server. While providing web-based services is one of those server-type options Linux does really well, the OS can do a lot more than host a blog about family outings.

If you’re looking to host your own services instead of paying for or relying on those in the cloud, running your own home server is a great way to keep your files private.

Choosing software

Choosing the specific Linux distributi­on for your home server can be daunting since there are so many strains to choose from. Most of the time, we just uses Ubuntu and recommend that first-time users do the same. The reason is simple: Ubuntu Server is easy to administer, well documented, and has a pretty low learning curve.

The next big thing you’ll have to worry about is what programs to run on the server. There is a huge amount of free and open-source software you can host yourself, but finding it can be tricky. Luckily, a GitHub user named Edward D. maintains a list of self-hosted software at tinyurl.com/nf9qfbr that you can run on a Linux server. The list has everything from blog software to

CRM. It even features some awesome meta packages (which let you bulk-install a group of applicatio­ns) like sovereign.

Indeed, sovereign is a good starting point for users who are looking to be digitally selfrelian­t. With a couple commands, sovereign will install an email server, a VPN service, nightly backups, a CalDAV and CardDAV server, and ownCloud, just to name a few.

Once you have an idea of what you want to host on your server, the next step is choosing the right hardware.

Choosing hardware

One of the most common ways to use Linux in a home server is to install the operating system on an old desktop.

The hardware requiremen­ts for Windows have marched forward as time and versions have progressed. While you might technicall­y get Windows 10 to run on a PC that’s been sitting in the garage for five years, its performanc­e might be less than ideal.

That old PC could be a nice host for Linux. On top of saving you some money, repurposin­g an old PC as a Linux server is good for the environmen­t. Reusing the PC keeps e-waste out of landfills and stretches the life of the heavy metals and precious and/or toxic materials that comprise many PC parts.

Raspberry Pi 3: £30 and up

There’s a reason people love the little Raspberry Pi. For £30 you get a palm-sized computer that has networking, USB ports and general-purpose pins to satisfy all of your tinkering needs. While the Pi is a great tinkerer’s toy, it’s also great as a low-power server.

It’s powered via a Micro-USB connection and sips power compared to big desktop components. If you’re looking for a server to host just a couple of services to a small number of users, the Pi is a wonderful platform to start with. It doesn’t have any storage on-board, but if you plan on running a file or media server with it you can always buy or reuse an external USB hard drive or a large USB stick.

NUCs and small PCs: £130 and up

Small PCs are often marketed as lowpowered desktops or home-entertainm­ent PCs, but they also make great servers. Intel’s Next Unit of Computing (NUC) models (see image below) are well equipped for light- to medium-duty server use in a home.

Much more robust than their ARM-based Raspberry Pi counterpar­ts, Intel’s NUCs will consume more power but be able to handle more computatio­nally intensive tasks. Some

NUC models will have room for a 2.5in SSD for onboard storage. Other models will force you to outsource bulk storage of big files to an external drive, not unlike the Pi.

If you prefer AMD to Intel, there are some other options as well, including Gigabyte’s Brix, which offers many of the same features as the NUC.

Network attached storage (NAS) appliances: £83 and up

If you’re worried you don’t have the technical chops to install and maintain your own Linux server, you can always go for a network-attached storage (NAS) system. A NAS is basically a small Linux or BSD server with the primary function of hosting files. You can think of a NAS as your own extensible Google Drive or Dropbox.

Lots of companies offer NAS solutions in one form or another, but two of the big names are QNAP and Synology. Both companies offer many of the same features, but the web interfaces are different for each.

For small businesses that just need something to work, a medium-sized NAS can

be a simple, plug-and-play solution. With a NAS, you generally don’t have to fight with drivers or settings during setup; everything can be accomplish­ed using an easy-to-follow web interface. While you can find diskless NAS devices for as little as £83, they will come without any hard drives. Hard drives for NAS boxes tend to cost a little more than the typical desktop hard drive, since they are designed to be always-on, and to keep data safe for a long period of time. (See our best NAS drive chart on page 138.)

Virtual private server (VPS): £3.50 per month and up

Okay, so this isn’t a way to have a Linux server in the home. A virtual private server is exactly what it sounds like: a virtual machine instance in a server farm. ‘Private’ refers to the fact that other VPS machines in the same server farm can’t steal resources or interact with your VPS. In effect, it’s like having your own little Linux box connected to a server farm somewhere.

VPS solutions can be great if you need to run a small blog or some other service that you’d rather not run from home. Unlike running a service on a home server, a VPS does not require you to open up ports on your router and fiddle with dynamic DNS.

Of the VPS providers out there, Digital Ocean offers some of the better deals for the individual or small business. Its servers start at £3.50 per month, and you can spin up more in seconds if you need them. Besides being a great way to learn how Linux works, running your own server at home can let you break away from commercial services and take back control of your data.
