What is Plex?

Plex, if you don’t already know, is a media streaming and sharing
tool which enables you to access any of your media content (videos,
films, tv music etc) anywhere in the world. It goes without saying that
you need a decent computer with a pretty good net connection to make
this viable. Thankfully I have both, as I think a lot of people do.
Happily for us, the wonderful people at Plex realise that not
everyone uses Windows.. or iOS.. or android and so make versions of
their apps for a myriad of different systems including Linux – hooray!

Let’s get started!

Your Plex installing experience starts on their website to download the media server itself. So go to the Plex download page now- make sure you download the correct version for your operating system of choice and whether you are 32bit or 64bit.


Since this tutorial is for Fedora users I will assume you’ve
downloaded your rpm and have saved it somewhere sensible (the Desktop is
not sensible you unorganised Windows user!)

Install the RPM

Now, if you have Yumex installed (a graphical front-end for Yum) you
should be able to find that file, double click it, enter your password
and voila it’s installed. If you don’t use yumex, or prefer not to (I
know… terminal is usually quicker than anything else) you can use the
command below to install it – just change the location and name of the
file to wherever yours is saved. Mine was something like this.

sudo yum install /home/bdavis/downloads/plexmediaserver_0.9.8.18.290-11b7fdd_x86_64.rpm

Now Plex is installed! You’re on your way to getting your content anywhere you go!

Start the service

Next up we actually have to start Plex, the following command will do
just that as well as create a symlink to always start Plex at boot.

sudo systemctl enable plexmediaserver.service && systemctl start plexmediaserver

If you’re prompted to enter your admin password do so.
Now you should be able to go to http://localhost:32400/web/index.html
and access Plex in almost all it’s glory! Why almost? Because now you
have a few more bits to iron out!

File permissions and access

Our first big problem (although it’s not really) is to allow Plex to
access any of our files. PMS runs as it’s own user (surprisingly a user
called plex), not you by default. So we need to give that user access to
your files. The easiest way to do this is to add the plex user to your
group. Type the following command in a terminal to do just that,
remembering to replace bdavis with your username.

sudo gpasswd -a plex bdavis

Now that’s done you can chmod the directory (or directories) in which
you keep all your files 755 to allow plex to read them. You can do that
with the following command, again make sure you change the directory to
match wherever your files are.

chmod 755 /mnt/storage

If you still have problems, open up your media folder and right click
on the containing folder and select properties. In the windows that
opens click the Permissions tab. It will look something like this:

For starters, make sure the last two drop down boxes say create and
delete files. Once that’s done click the button at the bottom “Change
Permissions for Enclosed Files…” (not sure why three of those words are
capitalised, nor why there are thre dots at the end… but hey ho).

Make sure again your drop down boxes look like mine then click the
change button. If you have a lot of media this could take a few seconds.
But once it’s done we can move onto the last step in this tutorial.

Set your Plex free!

The whole point of using Plex is to be able to access your media from
anywhere, however, Fedora (and rightly so) doesn’t by default want any
part of your system to be available anywhere. Se we need to let it know
certain ports are ok to use. Many people online have actually resorted
to disabling their firewalls to allow plex access. This is not necessary
or recommended!
Firstly, go back to your Plex web page and load up your settings, then click server and then the button “show advanced”.

You can see in this screenshot that my plex is completely accessible
by the outside world, yours right now will not be. So let’s change that.
Fire up your firewall, the easiest way is to open your dash and start
typing firewall.

Once you’ve opened your firewall gui (and entered your password to unlock it) this is what you will see.

Don’t be alarmed, we really don’t have to do much in here at all.
Firstly, where it says configuration there is a drop down box which two
choices, runtime or permanent – change it to permanent. Now that’s done
click the services tab near the top (the one next to zones)

In the screenshot above you can see where you should be – and you can
see the ports I have open on my desktop. Ignore all but the 32400 ones,
add your own as these are, on for UDP and one for TCP. When you’ve done
that you can close the firewall gui down (it saves changes as it’s
going along).
We’re almost there! Now just go back to your plex web page (to the
the settings page from earlier) click the tick box to manually specify
port then click apply. Assuming your router allows everything through
(and if not you can find how to here) you are good to go!
Enjoy your Plex wherever you are!

Any questions or problems, don’t hesitate to ask.
