Was just playing around. It’s a great home entertainment tool indeed.
Method-1: Creating repository and using Yum
To enable the Plex repository open your text editor and create a new YUM repository configuration file named plex.repo in /etc/yum.repos.d/ directory:
Method-2: Installation using RPM
download the package for your Linux distro. It is much easier to do this by simply coping the download link location with right click and then you can run:
$ sudo rpm -ivh https://downloads.plex.tv/plex-media-server/220.127.116.1195-10d48da0d/plexmediaserver-18.104.22.16895-10d48da0d.x86_64.rpm
Alternatively, you can download the package on your system with wget command as shown.
$ wget https://downloads.plex.tv/plex-media-server/22.214.171.12495-10d48da0d/plexmediaserver-126.96.36.19995-10d48da0d.x86_64.rpm
If you’ve used install base using yum repo- you now need to install it, otherwise if you’re with RPM installation, you already have plex installed.
