# Edit your /etc/yum.repos.d/plex.repo file, and change it to look like this:

[PlexRepo]
name=PlexRepo
baseurl=http://plexapp.com/rpmrepo/release/$basearch/
enabled=1
gpgcheck=0

 

This should auto pull the latest rpm from the official repo.

 

# yum list available | grep PlexRepo
plexmediaserver.x86_64 0.9.6.3.143-4466fb5 PlexRepo

 

In case you would like to use experimental version ( beta ), please add this to your plex.repo file

[PlexBetaRepo]
name=PlexBetaRepo
baseurl=http://plexapp.com/rpmrepo/beta/$basearch/
enabled=1
gpgcheck=0

 

When you would like to enable the pgpcheck option within you repository, set pgpcheck to 1 and import the pub key :

rpm --import http://plexapp.com/plex_pub_key.pub

 
CommandLine Tricks
 
Remove a Section from your Library
 

Sometimes it is needed to remove a section from your Library.
Unfortunately the Plex Media Manager does not allow you to remove a section.
 
This is how it can be done :

Windows

"c:\Program files (x86)\Plex\Plex Media Server\Plex Media Scanner.exe" -l
	1: Movies
	2: TV Shows
	3: TV Shows

"c:\Program files (x86)\Plex\Plex Media Server\Plex Media Scanner.exe" -D -c 3

"c:\Program files (x86)\Plex\Plex Media Server\Plex Media Scanner.exe" -l
	1: Movies
	2: TV Shows

OSX

"/Applications/Plex Media Server.app/Contents/MacOS/Plex Media Scannerquot; --list
"/Applications/Plex Media Server.app/Contents/MacOS/Plex Media Scannerquot; --del-section -c 3
