Installing Plex media server on a Raspberry Pi

This post was covers installing Plex media server on a Raspberry Pi 3 B+ running Raspbian Stretch Lite.

In this case I had already attached an external drive and set up Samba so I could easily add media files to the drive from my Windows PC. See this post for details.

Step 1

Firstly I added a new repository to apt so I could install it using apt-get. To do this I needed to get access to the repository.


First step was to download the key and add it to apt. I switched to be su for this. The commands below show what was run but not any of the resulting output.

sudo su
apt-key add dev2day-pms.gpg.key

Step 2

Then I created a new sources file for Plex.

cd /etc/apt/sources.list.d
sudo nano plexmediaserver.list

I then added the following line to the file and saved it.

deb stretch main

Note the version of Raspbian is Stretch. Modify the command for different versions.


Then I updated apt-get so it has the latest package lists.

sudo apt-get update

Step 3

Now I could install Plex.

sudo apt-get install plexmediaserver-installer

Step 4

I wanted to move the Plex database from the SD card storage in the Raspberry Pi to the external drive.

To do that stopped Plex before I moved the Plex library folder from its original location to a new location on the external drive. I then created a symbolic link to in place of the original folder that pointed to the new location. Once that had been done I could restart Plex. Plex would still look for its library in the original location but be redirected by the symbolic link.

sudo service plexmediaserver stop
sudo mv /var/lib/plexmediaserver /media/seagateHDD/plexmediaserver/
sudo service plexmediaserver start


Step 5

Then it was just a case of accessing Plex from a browser on my PC to check it was working. It was! I then started creating new libraries in Plex. The seagateHDD showed up nicely, along with the Media folder containing my video files.

The Plex server was available at
