Setup Plex Server with Raspberry PI 3 – Low Power Media Server

Plex Media Server is a service made specifically for a server or HTPC that allows you to stream your media anywhere and on any Plex compatible device. Besides streaming, this service processes your media and organizes it in beautiful libraries ready for consumption. If you want to use the transcoding function (where the Plex server reprocesses the video for Plex client), the Raspberry Pi Plex Media Server is not powerful enough, but it is good enough for direct play (no transcoding - heavylifting done by Plex client). We recently showed you how to install Plex media serveron Odroid C2, Windows, and Ubuntu Server. Today I will show you how you can setup Plex Server with Raspberry Pi 3.

Raspberry Pi Plex Media Server with Diet Pi OS

Before starting to setup Plex Server with Raspberry Pi 3, we first need to install an operating system. DietPi is one of the lightest operating systems available to date made specifically for low powered devices like the Raspberry Pi and Odroid. It has optimized software installers compiled specifically for the Raspberry Pi 3 that automate the install process, making the setup a simple process.

Before proceeding, you must follow and complete the Raspberry Pi 3 Diet Pi installation guide.

Next, connect the power cable to the Raspberry Pi 3 and the DietPi boot process will begin which takes about 2 minutes. Now all you need to do is wait for DietPi to display the IP where you can connect via SSH. You are now ready to setup your Raspberry Pi 3 Plex Media Server.

Connect to your Raspberry Pi 3 via SSH

Connecting to your Raspberry Pi 3 via SSH is really easy. You just need to use a SSH Client and enter the IP of the SSH device you want to connect to.

First, make sure you download Putty on your computer and open it. [Read: 10 best SSH Clients for Windows: free alternatives to PuTTY]

Next, type the IP for your device, the port (22 is the default port for SSH), and select SSH, then click on the Open button to start the connection.

A link to the Raspberry Pi will be made and the Login prompt will appear. For DietPi the default username is root and the password is dietpi.

If the credentials used are correct, DietPi will start it's automatic update process, to make sure you are using the latest version. This process usually takes about 5 minutes, so wait patiently until you get the confirmation that the update has been completed then press enter to reboot the device.

Next, choose if you want to setup a USB drive now or not. As the image shows, USB drive gives a better performance and generally more storage space than a SD card. We have separate guide on how to setup USB drive for storage on Diet Pi. Therefore, we will choose NO, with the assumption that you have already setup a USB drive following that. If not, select YES and setup the USB drive as described in the above guide. You may also select NO to use SD card for storage (not recommended).
