Advanced Server Settings
Plex Media Server has a number of advanced server settings that are not accessible from the Plex interface. Some settings can be accessed using the Plex Web App, while others can only be changed from outside of the Web app.
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.
Some of these settings are changed when you modify them to the suggested server settings.
Location of the advanced server settings
The location of the advanced server settings in Plex is different for each of the supported operating systems. For Windows, the settings are located in the registry, while other operating systems have a file in the data directory. The table below outlines where you can find the location of the Plex config file containing these server settings.
| Operating System | Location |
|---|---|
| Windows | HKEY_CURRENT_USER\Software\Plex, Inc.\Plex Media Server\ |
| macOS / OS X | ~/Library/Preferences/com.plexapp.plexmediaserver.plist |
| Linux | Preferences.xml file is located in the Plex Media Server data directory. |
| NVIDIA SHIELD | Preferences.xml file is located in the Plex Media Server data directory, but it isn’t accessible by a user. |
Available advanced settings
There are many different advanced settings for Plex Media Server that can be changed in the locations specified above. The various settings are outlined in the table below.
A few notes regarding Plex and Windows for the settings:
- The setting name is not case-sensitive in Windows. The setting name can begin with either a lowercase letter, as shown in the table below, or with an uppercase letter.
- A boolean value will be a DWORD type in the Windows registry. A true value will be 1, and a false value will be 0.

Fixing settings issues
If you have issues with your Plex server after changing any of the above advanced 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 advanced 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
