Here is the FAQ I wrote for Synology.
On Synology, we use /volume1/Plex (the “Plex” shared folder)
On regular linux, the top level directory changes
When you install using dpkg (downloaded from Plex)
the directory you’ll use is /var/lib/plexmediaserver
The structure you want to end up with is:
/var/lib/plexmediaserver/Library/Application Support/Plex Media Server
with all the subdirectories under it.
Plex Media Server is what you bring from Windows (just as shown in the Syno FAQ)
On regular linux, you’ll finish off with sudo chown -R plex:plex /var/lib/plexmediaserver
This gives the plex user ownership / permission to all its internal files.
When PMS starts up, you will need to claim it (the registry information is not carried into Linux. )
Once claimed, by default, the server’s friendly name will be the computer’s hostname.
