Install & Configure Plex#

With the Plex LXC running and storage mounted, install Plex Media Server and connect it to your libraries.

Install Plex on Debian#

Open a shell inside the Plex LXC and run:

apt update && apt install -y curl apt-transport-https
 
# Add the Plex repository key
curl https://downloads.plex.tv/plex-keys/PlexSign.key | gpg --dearmor -o /usr/share/keyrings/plex-archive-keyring.gpg
 
# Add the repository
echo "deb [signed-by=/usr/share/keyrings/plex-archive-keyring.gpg] https://downloads.plex.tv/repo/deb public main" \
  | tee /etc/apt/sources.list.d/plexmediaserver.list
 
# Install
apt update && apt install -y plexmediaserver
 
# Enable and start
systemctl enable plexmediaserver
systemctl start plexmediaserver

Verify it is running:

systemctl status plexmediaserver

Claim your server#

Go to https://plex.tv/claim and copy your claim token (it expires after 4 minutes).

Set the token and restart:

PLEX_CLAIM="claim-xxxxxxxxxxxxxxxxxxxx" systemctl restart plexmediaserver

Plex will register the server to your account automatically.

Open the web UI#

From a browser on your LAN:

http://<plex-lxc-ip>:32400/web

The setup wizard will guide you through the initial configuration.

Add media libraries#

In the Plex web UI, go to Settings → Libraries and add:

Library type	Path
Movies	`/mnt/media/movies`
TV Shows	`/mnt/media/tv`

These paths match what was mounted in the Mount Storage step.

Plex will scan the directories on startup. They will be empty until Sonarr and Radarr download something.

Set up scan notifications#

To make Plex scan immediately when Sonarr or Radarr imports a file:

In Plex, go to Settings → General and copy the X-Plex-Token from the URL
In Sonarr, go to Settings → Connect → Add → Plex Media Server and enter the Plex LXC IP and token
Do the same in Radarr

This triggers an instant library update after each import instead of waiting for a scheduled scan.

Result#

Plex is installed and connected to your media libraries. No media is available yet — that comes after configuring the download services.
