Installing Plex on Unraid

Plex is a popular media server that allows you to organize and stream your media content efficiently. Running Plex on your Unraid server is a great choice due to its reliability and 24/7 availability. In this tutorial, we will guide you through the process of installing Plex on Unraid, making it easy for you to enjoy your media library from anywhere.

1. Accessing the Unraid Apps

Begin by logging into your Unraid server and selecting the Apps tab in the interface.

2. Installing Plex via Docker

Search for Plex and choose to install the official Plex-Media-Server application. Note that Plex will be installed using Docker.

3. Configuring Plex Settings

  • Change the name to your preference.

  • Configure the settings as follows, replacing [Media] with your media folder location:

    • Host Path 2: /mnt/user/appdata/Plex-Media-Server/transcode
    • Host Path 3: /mnt/user/[Media]
    • Key 1: [Plex Claim Code]


  • Host Path 2 maps the transcode volume to a new Plex-Media-Server folder, which is where Plex’s configuration will reside.
  • Host Path 3 (/mnt/user/Media) is where your media is stored on Unraid. Make sure all your media files are located in this folder.
  • You can generate a Plex Claim Code on the Plex website and paste it into Key 1 to link the Plex instance to your user account.

4. Advanced Configuration

Scroll to the bottom and select “Show more settings.” The path shown is where Plex Media Server’s configuration data will be stored. If you ever need to back up or move your configuration, use this folder.

5. Auto-Start Plex

Go to the Docker tab and enable Autostart to ensure Plex starts automatically when Unraid boots up.

6. Access Plex

You can access Plex by navigating to http://[UNRAID_IP]:32400/web/index.html. If you used a Plex Claim Code, you won’t need to claim the Plex server again after logging in.

7. Set Up Your Media

You will need to complete the Plex setup process, adding your media files. Keep in mind that we mapped all media files to the /data location, so set up different folders for Movies, Music, TV Shows, etc.

8. Enjoy Your Plex Server

After configuring Plex, your media library should be accessible and ready to stream.


While the installation process isn’t overly complicated, it’s crucial to correctly specify the media folder so that Plex can locate your data. Remember that all critical data for this container resides in the /mnt/user/appdata/Plex-Media-Server/ location, so if you ever plan to relocate your Plex server, make sure to copy that folder to the new location.
