I would have been really nice to know this before chasing down red herrings caused by completely a completely non-standard installation.
- Moving
/var/lib/plexmediaserver(your metadata) is 100% normal and expected. I have How-To’s on accomplishing this. Linux Tips - Moving the PMS executables is not supported. They are under the control of
rpm. - Modifying
/lib/systemd/system/plexmediaserver.serviceis pointless. I overwrite it with each update. - Local configuration customizations are supported through the systemd standard override.conf file and so documented in the Linux Tips linked above.
Please remember, the executables belong in root and /usr/lib. It’s ~120 MB fully expanded.
Your metadata, which can grow to 10-15-20 GB, is fully relocatable.
Because they are stored in different locations, they are independent of each other. I do not remove your library data should you uninstall the binaries. This allows for downgrading version with ease.
How can I now assist you in bringing this into proper operational status with a configuration which works for you ?
