How to Install Plex on the Raspberry Pi 4
The Raspberry Pi, with its tiny footprint and low power draw makes for the perfect network-attached storage (NAS) device. There are several means of spinning up a Raspberry Pi media server, but my favorite option is Plex. The robust media server software option offers a comprehensive feature set that's at once easy to use and highly customizable. Learn how to make a Raspberry Pi Plex server for an affordable Plex streaming device!
What is Plex Media Server?
Plex is a media server software offering. You can think of it as a sort of do-it-yourself Netflix. Whereas streaming subscription services like Hulu and Netflix host content, with Plex you provide content such as movies, TV shows, and music. Then, Plex scrapes your libraries and adds box art and metadata for a lush user interface. Aside from videos and audio, Plex can host photos as well. Aside from a Raspberry Pi, Plex can run on Docker, Linux, macOS, Windows, and FreeBSD.
Why You Should Use Plex for a Raspberry Pi Media Server
My Plex journey began in 2016 when I began ripping my DVDs and Blu-Rays. Initially, I ran a Plex server off of an aging AMD A10 APU-powered HP laptop before graduating to a Xeon-powered Lenovo ThinkServer TS140. While I'm still a dedicated collector of physical media, from VHS tapes and LaserDiscs to DVDs, Blu-Rays, and vinyl, having my entire movie, TV show, and music collection backed up on my Plex server is a huge bonus. Discs can get scratched and suffer from disc rot, so a back up digital copy means extra redundancy. Sure, hard drives are far from infallible. But you can easily back your digital media collection to onsite drives or cloud storage providers.
Plus, there's the convenience of being able to access my media library from anywhere. If I'm on vacation and want to watch a movie, I can merely pull it up on a Plex client such as my phone, tablet, or laptop. Furthermore, Plex evolved into the ultimate app for cord-cutters. While it began with a media server focus, Plex added features such as podcasts, web shows, streaming news, Tidal integration, DVR functionality, and now free ad-supported movies and TV shows thereby positing it as a true cord-cutting haven.
- Stream your movie, TV show, and music collection to compatible client devices
- Cord-cutting features such as ad-supported streaming movies and TV shows, Tidal integration, web shows, and podcasts
- Easy to use yet highly customizable
Can the Raspberry Pi Run a Plex Server?
Considering its modest specs, you might wonder if a Raspberry Pi can even run a Plex server. While you can create a Raspberry Pi-based Plex server, performance won't match that of a dedicated server, or even an older laptop or desktop. Still, the price-to-performance ratio is fantastic. Plus, the Pi sips energy whereas even a low-power server that's always-on will still drive up your energy bill at least a bit.
Although you technically can transcode on a Raspberry Pi Plex media server, you can't transcode well. This is a project mostly suited to in-home streaming to direct-play compatible Plex clients. Any Raspberry Pi 2 or newer board should be able to handle Plex server use. However, I'd suggest at least a Raspberry Pi 3 B+ or, better yet, a Raspberry Pi 4 Plex server.
- Great for in-home streaming
- Can transcode but not well
- Excellent for direct play
- Low power
- Small footprint
- Affordable Plex server solution
How to Make a Raspberry Pi Plex Server
Building a Raspberry Pi Plex server is pretty easy. You'll need little more than a Raspberry Pi board, microSD card, case, peripherals such as a keyboard and mouse, as well as an active internet connection. Additionally, you'll need to install software, namely Plex media server for the Pi. Depending on the size of your media collection, you'll probably want a large capacity flash drive or external harddrive. Finally, you'll need a Plex client device, or another device that you can stream Plex to. This could be simply a Windows, macOS, or Linux PC, a game console like a PlayStation 4 or Xbox One, dedicated streaming device such as a Roku, or even another Raspberry Pi board.
What you need to make a Raspberry Pi Plex server:
- Raspberry Pi board (Raspberry Pi 2 or newer)
- microSD card
- Raspberry Pi case
- Compatible Raspberry Pi power supply
- Debian Linux-based Raspberry Pi operating system (i.e. Raspbian)
- Peripherals (keyboard, mouse)
- Plex media server software
- Plex client
Total cost: $35+ USD. You can snag the base Raspberry Pi 4 for a mere $35 for the standalone 1GB Raspberry Pi board. Then the 2GB RAM model retails for $45, while the 4GB Raspberry Pi variant clocks in at $55. If you're just starting out, I highly suggest snagging a complete Raspberry Pi kit. Especially if you're streaming and using your Raspberry Pi as a NAS, you'll want to keep your device cool, and a case with a heatsink goes a long way in that. Plus, many Raspberry Pi starter kits include a microSD card.
How to Set Up a Raspberry Pi Plex Server - Install Plex Media Server on the Raspberry Pi
Before proceeding with using your Raspberry Pi as a Plex server, as with any software installation, it's best to perform an update. In a new terminal, run:
sudo apt-get update
sudo apt-get upgrade
After that, you'll need to install Plex Media Server on your Raspberry Pi. Head over to Plex.tv and download the appropriate version of Plex Media Server. You'll want to select Linux. Then, Choose Distribution. For the Raspberry Pi, pick either the ARMv8 or ARMv7 installer. If you're running a 32-bit OS, pick the ARMv7 Plex Media Server option. But for a 64-bit operating system opt for ARMv8. This will download a DEB file. Once the PMS for Plex DEB file is completely downloaded, launch it. You'll be prompted to enter your password. You should be able to head to
localhost:32400/web on your Pi, or
[RASPBERRY PI IP]:32400/web on another machine on the same network where you can begin to configure Plex on the Raspberry Pi.
Setting a Static IP on the Raspberry Pi
Although your Raspberry Pi Plex media server should be technically ready to begin streaming, it's a best practice to establish a static IP on your Raspberry Pi. To set a static IP address on your Raspberry Pi, enter the command:
Next, open up
sudo nano /boot/cmdline.txt
Where there's the line IP, enter your IP address:
ip=RASPBERRY PI IP ADDRESS
After you've input your Raspberry Pi's IP address, hit CTRL + X, then Y to save. Once you've configured a static IP address on your Raspberry Pi Plex server, restart your device:
Adding External Media to the Raspberry Pi
If, like me, you've got a massive media collection, your Raspberry Pi microSD card might not be sufficient to hold your entire media library. As such, you'll need to use an external drive such as a flash drive or hard drive.
To see where drives are mounted, run:
sudo cat /proc/mounts
This lists a string of any connected USB drives. For instance, my 1 TB external harddrive appeared under
Alternatively, you may prefer to manually mount a USB drive in the Raspberry Pi. You can accomplish this pretty easily by establishing the drive under the fstab file. If you're using an NTFS drive, install the NFTS 3G package:
sudo apt-get install ntfs-3g
If you know the UUID, you can enter that. To discover the UUID, you can obtain a list of all connected drives with:
ls -l /dev/disk/by-uuid
Find a drive with an
/sda address, such as
/dev/sda1. After that, you should see a string that's the UUID.
Then, create a new directory to mount the USB to:
sudo mkdir /media/usb1
Find out the GID with:
id -g pi
And locate the UID using:
id -u pi
After that, edit the fstab file:
sudo nano /etc/fstab
Add a line with the necessary information about your external drive:
UUID=NAME OF DRIVE /media/usb1 auto nofail,uid=your_uid_here,gid=your_gid_here,noatime 0 0
Save and exit with CTRL + X, then Y. You'll need to unmount the drive:
sudo umount /dev/sda1
Then mount your drives with:
sudo mount -a
And you can restart your Raspberry Pi Plex server to double-check that all drives have properly been mounted:
Upon rebooting, your external drives should auto-mount.
Configure Plex on the Raspberry Pi
With Plex installed and your external drives set up, it's time to configure Plex on the Raspberry Pi and point it toward your media library. Head over to
localhost:32400/web/ where you should see the Plex log in screen.
First up, you'll need to name your server. I went with RasPlexPi but you can give your Pi server whatever name you like. Hit Next and point your Plex server software towards your media libraries. On my external drive, I've got a media folder at the root of my drive with subfolders for movies, TV shows, and music. Click Add Library, and select the library type, such as movies, TV shows, music, photos, or other videos. Then, find the folder where your media files are located and they'll be added to your library.
Raspberry Pi Plex Server Performance
Ultimately, Raspberry Pi Plex server performance will vary based on the specific files you're streaming, what clients you're streaming on, and your internet connection. Likewise, which Raspberry Pi board you're running Plex on affects streaming performance. However, generally a Raspberry Pi 4 Plex server will provide the best experience. Can a Raspberry Pi transcode in Plex? Yes, although not well, and not smoothly. You'll definitely experience buffering for Pi Plex transcoding. As such, direct play works much better.
1080p direct play files work extremely well on a Raspberry Pi 4. Moreover, a Raspberry Pi 4 can handle about 4 or 5 simultaneous direct play files. For in-home streaming, the Pi 4 is a great Plex server option. What really surprised me was that my Raspberry Pi Plex server handled 4K direct play. Transcoding is out of the question, but that's incredibly impressive.
Is the Raspberry Pi Good for a Plex Server?
Now, the big question: Is the Raspberry Pi good for a Plex server? Absolutely, but with a caveat. As long as your Plex clients and files allow for direct play, you're streaming in your home as opposed to remote, and don't need to exceed around four or five simultaneous direct play streams, a Raspberry Pi Plex server is a cost-effective, energy-conserving Plex server alternative. With a starting price tag of just $35, it's super easy to whip up a Plex media server with a Raspberry Pi.
Admittedly, my Pi Plex server isn't going to replace my beefy Xeon-powered TS140. My 24/7 dedicated Plex server can handle around four simultaneous 1080p transcodes, and can easily transcode 4K Blu-Ray rips. The Pi can't even come close. Still, it's much more than the price of a Raspberry Pi, and the modest standard desktop PC case features a much larger footprint than the Pi. Similarly, despite its low power draw, my Lenovo server is power-hungry when compared to the Raspberry Pi. If you're merely serving media to clients around your house, a Raspberry Pi Plex server is an excellent media server solution that won't break the bank. For streaming media and local file playback, transform your Raspberry Pi into a low-power home theatre PC.
