Hidden Server Settings

Plex Media Server has a number of hidden server settings that are not accessible from the Plex interface. These settings can only be accessed and changed from outside of the Plex interface.

Most users, however, will not need to change these Plex server settings, and doing so can cause problems with your Plex Media server. If you would like to find and change these settings, you can use the information below.

Fixing settings issues

If you have issues with your Plex server after changing any of the above hidden settings, such as some Plex server settings missing, you can reset the values back to default by deleting either the preferences file or the keys in the Windows registry.

Deleting the preferences file will reset any changes you have made, and you will also lose any server shares or Mobile Sync items you may have. Your Plex Media Server library database will not be affected.

SysLog option

In addition to the above hidden settings, you can also have Plex enable syslogging on a Linux-based system. This can be done by setting the configuration variable: PLEX_MEDIA_SERVER_USE_SYSLOG=true.

The variable will need to be added to the Plex Media Server configuration file. This file is located in the following locations:

CentOS/Fedora

Value: export PLEX_MEDIA_SERVER_USE_SYSLOG=true

Config File Location: /etc/sysconfig/PlexMediaServer

ReadyNAS

Value: export PLEX_MEDIA_SERVER_USE_SYSLOG=true

Config File Location: /etc/init.d/plexserver

Synology

Value: PLEX_MEDIA_SERVER_USE_SYSLOG=true

Config File Location: /var/packages/Plex Media Server/scripts/start-stop-status

Ubuntu 15 (and older)

Value: PLEX_MEDIA_SERVER_USE_SYSLOG=true

Config File Location: /etc/default/plexmediaserver

Ubuntu 16 (and newer)

Value: Environment="PLEX_MEDIA_SERVER_USE_SYSLOG=true"

Config File Location: /etc/systemd/system/plexmediaserver.service.d/override.conf
