The awesome Plex Media Server can now finally be installed on the Raspberry Pi 2 without a chroot. The chroot method broke when using upstart scripts and had metadata issues, those are no longer a problem! Using a Synology package compiled for an ARMv7 processor we can use it on the Pi 2 with a bit of extra work.

This will unfortunately not work on the B+ or earlier models as they use an ARMv6 processor. Many thanks to uglymagoo from the Plex forum who identified the package that could be used without a chroot on the Raspberry Pi 2. I used a minimal Raspbian distribution Minibian for this guide, when you are done Plex will also autostart on boot. There is also a link to an image at the bottom of this post with Minibian and Plex installed, please share this post if you use the image. This how-to also has a section on fixing Plex permissions so if your Plex can't see your folders then you will be able to solve that problem here.

March 2016 Update: Jessie Image posted compatible with Raspberry Pi 2 and Pi 3

Previous Update: Method 3 for early Plex releases now working with Jessie

Image Updated August 2015 to version 6 with Minibian Jessie with Kernel 4.1 and Plex 0.9.12.8 (if you experience issues use this image use the installer)

Instructions Updated for Plex 0.9.12.8 on Raspbian Wheezy start at Pre-install requirements

There are also Media Server and HTPC Combo Images available here that combine Kodi, usenet and torrent automation.

Plex for ARM CPU architectures is compiled with very limited transcoding abilities. Do not expect transcoding to work, you will get the best experience by using DirectPlay or DirectStream features of Plex streaming locally. H264 content should play remotely as long your internet connection can support it and client can play back the media's codecs. If your content has subtitles it will not work for transcoding.

The Banana Pi can run Plex Media Server as well and sports a SATA and gigabit port for extra speed (see benchmarks).

Guides for other ARMv7 processors are available: ODROID-C1, Orange Pi and Banana Pi. This guide has been split up into four methods in order of easiest to hardest. You must start with the pre install section to make sure the locales are in order before you proceed to the other methods, I recommend using the repository as it is easiest and fastest.

Now there is a guide to install the Plex UnSupported AppStore

Many users want to mount their hard drives, here is a guide for that so you can find your media in Plex

Install Plex Media Server on Raspberry Pi 2

Installation Checklist

This guide is rather long and easy to overlook things so here is a checklist of what you need to do

Verify you have the en_US locale

Verify you have the libc6 2.19 if you want to use the latest Plex Media Server

Make sure you have libexpat1 installed

Make sure you are using the right repository – must be jessie if you want the latest and greatest

Move the transcoding folder to your external hard drive

Do not use WiFi if you want the best results

Stick to Method 1 for installation

Avoid using Plex.tv to connect as it can override the force transcoding, only use your local IP address or dynamic DNS address

Monitor Plex Media Server and restart it automatically with this guide.

Do not use Plex.tv instead use Dynamic DNS and a reverse proxy with this guide.

Fix Plex permissions (at the bottom of this post)

If you are having problems with video playback you can use an older transcoder with this guide.

Pre-Install Requirements

Generate Locales

This command lists current locales and fix any locale error (otherwise see the comments from Jason)

locale -a

My output looks like this

C C.UTF-8 en_US.utf8 POSIX

If you don't have en_US.utf8 you can generate it

To generate the locale edit the locale generator configuration file first to enable the locale

sudo nano /etc/locale.gen

Uncomment this line by deleting the #

# en_US.UTF-8 UTF-8

Ctrl+X, Y and Enter to save

Now generate the locales

sudo locale-gen

If you get the locale-gen cannot be found error it is probably because you are on Minibian, use this command

echo "export PATH=$PATH:/usr/sbin" >> ~/.profile

Now generate the locales again if you get the locale-gen cannot be found error

sudo locale-gen

Reconfigure locales for good measure (source)

sudo dpkg-reconfigure locales

Upgrade libc6 to 2.19 on Raspbian

As of Plex 0.9.12.8, version 2.19 of libc6 is required, Wheezy (the current prevalent repo) only has version 2.13. You can install version 2.19 manually though but it involves pinning apt sources which can cause other issues. If you don't care about having the latest and greates version then you can just use uglymagoo's Wheezy repo. I recommend backing up your SD card before manipulating your packages.

Make sure you have read the warnings above and have backed up or are using an extra SD card.

Check which version of the glibc6 you have by typing this command

ldd --version

If the output says 2.13 upgrade manually by following the next few steps, if it says 2.19 then you can skip ahead to installing from uglymagoo's repository in the next section

Add Jessie repositories

echo "deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free" | sudo tee -a /etc/apt/sources.list echo "deb http://archive.raspbian.org/raspbian jessie main contrib non-free" | sudo tee -a /etc/apt/sources.list

Create the jessie preferences file so we can control it

sudo nano /etc/apt/preferences.d/jessie.pref

Paste this code. Pinning forces jessie to be of a lower priority so it doesn't conflict with existing packages, a value of -1 means only packages we specify to be installed from jessie will be installed from there, no other packages should be affected unless they are dependencies.

Package: * Pin: release n=jessie Pin-Priority: -1

Now Ctrl+X, Press Y and then Enter

Update packages

sudo apt-get update

Install libc6 from the Jessie repository

sudo apt-get install -t jessie libc6 -y

When prompted say yes to restart services automatically under installation

Now you should have libc6 version 2.19. Check the version again

ldd --version

If it still says any version below 2.19 here is how to fix it by changing pin preferences.

sudo nano /etc/apt/preferences

Add this information or adjust your pin priority so it matches

Package: * Pin: release n=wheezy Pin-Priority: 989

Ctrl+X, Y and enter to save

sudo apt-get update sudo apt-get install -t jessie libc6 -y

If you ever experience issues when installing other packages in the future you may need to install dependencies like this

sudo apt-get install -t jessie packagename

Method 1 – Install Plex Media Server on Raspberry Pi 2 using Repository

Enable https transport or you will get this error: E: The method driver /usr/lib/apt/methods/https could not be found.

sudo apt-get update && sudo apt-get install apt-transport-https binutils -y --force-yes

Grab uglymaoo's gpg key for his repository

wget -O - https://dev2day.de/pms/dev2day-pms.gpg.key | sudo apt-key add -

Add uglymagoo's repository, if your ldd –version output said 2.19 or you have updated manually using the steps above, leave it as jessie. If you don't care about having the latest version you can change jessie to wheezy in the line below

echo "deb https://dev2day.de/pms/ jessie main" | sudo tee /etc/apt/sources.list.d/pms.list

Update your package lists

sudo apt-get update

Install Plex Media Server

sudo apt-get install plexmediaserver-installer -y

If you manually installed libc6 2.19 use this command to specify installation from the jessie repository

sudo apt-get install -t jessie plexmediaserver-installer -y

When you know there is a new version of Plex Media Server you can upgrade with this command now

sudo apt-get update && sudo apt-get upgrade -y

Access Plex on your Raspberry Pi 2 at this URL, replace ip.address with your actual local IP http://ip.address:32400/web or http://ip.address:32400/manage/index.html#!/setup

If it hasn't started then you may have a systemd / init.d issue which can happen if you are on Debian jessie, start Plex manually like this, the & puts in the background. If you are troubleshooting leave out the & to get some error information.

sudo bash /usr/lib/plexmediaserver/start.sh &

Go shopping for a new hard drive at Amazon to store your media

Read about usenet for grabbing content automatically.

If you need to remove Plex you can do so with this command

sudo apt-get remove plexmediaserver -y

Method 2 – Old Easy Install Method

This method grabs the latest package straight from uglymagoo's repository. It was used before uglymagoo created a repository and is only here for the sake of completion.

Enter your temp folder, this will ensure the package is emptied after you reboot

cd /tmp

Remove any existing plex package in case you are upgrading to the newest version from an older version

rm plexmediaserver_*.deb

Grab the latest Plex Media Server package link from here, you must know if you are on Wheezy or Jessie

Replace the http link below with the link you copied.

wget http://dev2day.de/plex-latest

Install the latest Plex Media Server Package

sudo dpkg -i plex*

It will autostart on boot when you restart your machine, go to http://ip.address:32400/web and Plex should pop up

You can start and stop the service with this command, replace restart with start or stop as you see fit

sudo service plexmediaserver restart

If you want to remove plex using this method

sudo dpkg -r plexmediaserver

You do not need to read the rest of this guide but can now configure Plex or install some transcoding tools at the bottom of this post.

Method 3 – Build the Plex Media Server Package

This method is deprecated, see the new manual installation guide.

With this method you are going to grab the latest plex ARMv7 Synology package straight from Plex and turn into a deb package you can install on your Raspberry Pi 2.

First you may need to install patchelf for updating symlinks for the libc6 library

This step may not be necessary so only do it Plex doesn't start after building and installing the package

sudo apt-get install build-essential autoconf automake git -y git clone https://github.com/NixOS/patchelf cd patchelf autoconf ./bootstrap.sh automake ./configure --prefix=/usr sudo make make install

Enter home directory

cd ~

Grab the latest Plex skeleton package

wget http://dev2day.de/skeleton.tgz

Unpack the Plex skeleton

tar -xzf skeleton.tgz

Grab the latest Plex Media Server package link for ARMv7 which can be found at https://plex.tv/downloads click NAS.



Click the Synology tab and right click on the ARMV7 button and copy the link to the clipboard.

Back in SSH type wget and paste the link you have copied to the clipboard, trim the s from https as well if you have issues

wget https://downloads.plex.tv/plex-media-server/0.9.12.19.1537-f38ac80/PlexMediaServer-0.9.12.19.1537-f38ac80-arm7.spk

Rename the Synology Plex package, replace the filename here with the filename of the newest package you just downloaded.

mv PlexMediaServer-0.9.12.19.1537-f38ac80-arm7.spk PlexMediaServer-0.9.12.19.1537-f38ac80-arm7.tgz

Unpack the Plex package, again replace the package name

tar -xvf PlexMediaServer-0.9.12.19.1537-f38ac80-arm7.tgz

Unpack the package to the skeleton directory

tar -xvf package.tgz -C skeleton/usr/lib/plexmediaserver

Delete unnecessary stuff

rm -r skeleton/usr/lib/plexmediaserver/dsm_config

Enter the plexmediaserver folder

cd skeleton/usr/lib/plexmediaserver

Create some symbolic links, skip the red lines and only use it if the first build doesn't work

find . -executable -type f -exec patchelf --set-interpreter /lib/ld-linux-armhf.so.3 {} \; ln -s /lib/ld-linux-armhf.so.3 /lib/ld-linux.so.3 find . -iname "*.so" -exec chmod 644 {} \; find . -iname "*.so.*" -exec chmod 644 {} \;

Go back to the home directory

cd ~

This is optional, you can edit the package details

nano skeleton/DEBIAN/control

Change Maintainer if you want and adjust the version

Package: plexmediaserver Version: 0.9.11.7.803-87d0708-3 Architecture: armhf Maintainer: Jan Friedrich (uglymagoo) <jft@dev2day.de> Section: video Priority: extra Homepage: http://www.plexapp.com Description: Plex Media Server for Linux Stream media everywhere(tm)

Install fakeroot

sudo apt-get install fakeroot -y

Build the deb package for installation

fakeroot dpkg-deb --build skeleton ./

You can now install the plexmediaserver package you just created

sudo dpkg -i plexmediaserver*

If all went well you can remove the files and folders you used to build the package

rm skeleton.tgz rm -R ~/skeleton rm plex*.deb

Install the transcoding tools at the bottom of this post.

Method 4 – Manual Plex Installation

The following section is only necessary if the above methods do not work. I will update this section to mimic the exact paths from the package above to avoid any future confusion if methods are mixed. It is based on the chroot guide.

Plex is updating packages so often it is worth making sure you are grabbing the latest package by grabbing the newest download link as outlined in Method 2 and using the new file name in the 3 relevant lines below).

Enter your home directory

cd ~

Create a plex directory to work with

mkdir plex

Enter the plex working directory

cd plex

Grab the Synology arm7 package (update new name if you want the latest package for the next 3 commands)

wget https://downloads.plex.tv/plex-media-server/0.9.12.19.1537-f38ac80/PlexMediaServer-0.9.12.19.1537-f38ac80-arm7.spk

Rename the Synology arm7 package to tar so it can be unpacked and used on the Raspberry Pi 2

mv PlexMediaServer-0.9.12.19.1537-f38ac80-arm7.spk PlexMediaServer-0.9.12.19.1537-f38ac80-arm7.tar

Unpack the Plex Media Server tar package

tar -xvf PlexMediaServer-0.9.12.19.1537-f38ac80-arm7.tar

Create a directory for plex

sudo mkdir -p /opt/plex/Application

Unpack the Plex package to the plex folder you just created

sudo tar -xvf package.tgz -C /opt/plex/Application

Create a symlink for this file

ln -s /lib/ld-linux.so.3 /lib/ld-linux-armhf.so.3

Make sure you have the en_US.utf locale or you will get this error

terminate called after throwing an instance of 'std::runtime_error'

what(): locale::facet::_S_create_c_locale name not valid

or this error

start.sh: line 8: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8): No such file or directory terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid

This command lists current locales and fixes the locale error above

locale -a

My output looks like this

C C.UTF-8 en_US.utf8 POSIX

If you don't have en_US.utf8 you can generate it or modify the plexmediaserver file further below to use your locale

To generate the locale edit the locale generator configuration file first to enable the locale

sudo nano /etc/locale.gen

Uncomment this line by deleting the #

# en_US.UTF-8 UTF-8

Ctrl+X, Y and Enter to save

Now generate the locales

sudo locale-gen

Now run Plex for the first time!

Enter your plex directory

cd /opt/plex/Application

Start Plex Media Server to see if it's working

sudo bash start.sh &

Browse to http://ip.address:32400/web and Plex should pop up!

Configure Plex Media Server to Autostart on Boot

This is for the manual method only!

To get Plex to start on boot, create this file

sudo nano /usr/local/bin/plexmediaserver

Paste this inside

#!/bin/sh SCRIPTPATH=/opt/plex/Application export LD_LIBRARY_PATH="${SCRIPTPATH}" export PLEX_MEDIA_SERVER_HOME="${SCRIPTPATH}" export PLEX_MEDIA_SERVER_MAX_PLUGIN_PROCS=6 export LC_ALL="en_US.UTF-8" export LANG="en_US.UTF-8" export PLEX_MEDIA_SERVER_APPLICATION_SUPPORT_DIR="/opt/plex/Application/Library/Application Support" ulimit -s 3000 /opt/plex/Application/Plex\ Media\ Server

Ctrl+X, Y and Enter to save and exit

Make the plexmediaserver file executable

sudo chmod +x /usr/local/bin/plexmediaserver

Create the init.d script to start and stop plexmediaserver on the Raspberry Pi 2

sudo nano /etc/init.d/plexmediaserver

Paste this slightly modified PMS script

#!/bin/sh ### BEGIN INIT INFO # Provides: plexmediaserver # Required-Start: $remote_fs $syslog $networking # Required-Stop: # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Plex Media Server # Description: Plex Media Server for Linux, # More information at http://www.plexapp.com # Many thanks to the great PlexApp team for their wonderfull job ! # Author: Cedric Quillevere / origin@killy.net # Rewamped Christian Svedin / christian.svedin@gmail.com # Adapted (cubox-i) Francis Belnger / francis.belanger@gmail.com # Version: 1.2 ### END INIT INFO # Read configuration variable file if it is present [ -r /etc/default/plexmediaserver ] && . /etc/default/plexmediaserver test -f "/usr/local/bin/plexmediaserver" || exit 0 plex_running=`ps ax | grep "/opt/plex/Application/Plex Media Server" | awk '{ print $1 }' | wc -l` case "$1" in start) if [ "$plex_running" -gt 1 ]; then echo "Plex already running..." exit 0 fi echo -n "Starting Plex Media Server: " su -l $PLEX_MEDIA_SERVER_USER -c "/usr/local/bin/plexmediaserver &" >/dev/null 2>&1 sleep 1 echo "done" ;; stop) if [ "$plex_running" -eq 1 ]; then echo "Plex Media Server is not running (no process found)..." exit 0 fi echo -n "Killing Plex Media Server: " # Trying to kill the Plex Media Server itself but also the Plug-ins ps ax | grep "Plex Media Server" | awk '{ print $1 }' | xargs kill -9 >/dev/null 2>&1 ps ax | grep "Plex DLNA Server" | awk '{ print $1 }' | xargs kill -9 >/dev/null 2>&1 sleep 1 echo "done" ;; restart) sh $0 stop sh $0 start ;; status) if [ "$plex_running" -gt 1 ]; then echo "Plex Media Server process running." else echo "It seems that Plex Media Server isn't running (no process found)." fi ;; *) echo "Usage: $0 {start|stop|restart|status}" exit 1 ;; esac exit 0

Ctrl+X, Y and Enter to save the Plex Media Server script

sudo chmod +x /etc/init.d/plexmediaserver

Update rc to enable your new Plex Media Server script

sudo update-rc.d plexmediaserver defaults

Create the /etc/default/plexmediaserver file

sudo nano /etc/default/plexmediaserver

Paste this, it is also here you can adjust the user the plex service runs as and the transcoding directory which should be your external hard drive

# default script for Plex Media Server # the number of plugins that can run at the same time PLEX_MEDIA_SERVER_MAX_PLUGIN_PROCS=6 # ulimit -s $PLEX_MEDIA_SERVER_MAX_STACK_SIZE PLEX_MEDIA_SERVER_MAX_STACK_SIZE=3000 # where the mediaserver should store the transcodes PLEX_MEDIA_SERVER_TMPDIR=/tmp # uncomment to set it to something else # PLEX_MEDIA_SERVER_APPLICATION_SUPPORT_DIR="${HOME}/Library/Application\ Suppo$ # the user that PMS should run as, defaults to 'plex' # note that if you change this you might need to move # the Application Support directory to not lose your # media library PLEX_MEDIA_SERVER_USER=plex

Ctrl+X, Y and Enter to Save

Reboot and you are all ready to start adding media to Plex and stream it around your home!

sudo reboot

Transcoding Tools

Plex Media Server requires a new libc6 module that you can pull from the jessie repo (thanks again to uglymagoo). This part may not necessary if you used the precompiled deb package at the top.

Install libexpat1 for help playing in the Android app

sudo apt-get install libexpat1 -y

These mkvtools can help but are possibly unnecessary

sudo apt-get install mkvtoolnix -y

It may help enable XviD, DivX and MKV playback in the Plex web interface and in the Plex app.

If you already have libc6 2.19 you can skip the next 3 steps and go to Use Hard Drive for Transcoding.

Stop your Plex server first

sudo service plexmediaserver stop

This next block should no longer be necessary and is here for archival purposes only. Grab the package, extract the libc6 file and place it in the Plex Media Server folder. The libc6 is from the jessie testing repo can is updated from time to time, if you get a not found error try incrementing the version by 1 or 2 so that the filename is for example: libc6_2.19-19_armhf.deb.

If you used method 3 replace /usr/lib/plexmediaserver with /opt/plex/Application

cd /tmp/ mkdir libc6 cd libc6 wget http://ftp.us.debian.org/debian/pool/main/g/glibc/libc6_2.19-18_armhf.deb dpkg-deb -x libc6_2.19-18_armhf.deb ./ cp -a lib/arm-linux-gnueabihf/libm-2.19.so /usr/lib/plexmediaserver cd /usr/lib/plexmediaserver chmod ugo+x libm-2.19.so unlink libm.so.6 ln -s libm-2.19.so libm.so.6

Restart your Plex server

sudo service plexmediaserver restart

Fix Plex Permission Issues

If Plex isn't reading your drives or folders you can do one of two things, change the permissions of your external storage or change the user Plex is running as (which could mean you need to rescan for metadata).

First try adding your plex user to your regular user's group that owns the mount point for your hard drive

sudo usermod -aG pi plex

Then add your regular user to the plex group if the plex group exists

sudo usermod -aG plex pi

Then set the permissions for the folder containing your media to 775 so the plex in the user's group can read them

sudo chmod -R 775 /folder/with/media

If that still fails you can change the permissions where /mnt/usbstorage is your mount path for your hard drive so everybody can read, write and execute

sudo chmod -R 777 /mnt/usbstorage

Alternatively you can change the user Plex runs as to your pi user

To change which user Plex runs as, open this file

sudo nano /etc/default/plexmediaserver

Change this line, replace plex with your username you use to log on or the owner of the mounted drive, most likely pi

PLEX_MEDIA_SERVER_USER=pi

Ctrl+X, Y and Enter to save

Then restart your Plex server

sudo service plexmediaserver restart

Use Hard Drive for Transcoding

You should set Plex to use your external hard drive for temporary transcoding data after you have mounted your drives properly.

Click the settings icon in the top right, Click Server and then Transcoder in the left pane.

Make sure SHOW ADVANCED is enabled underneath Server.

Scroll down to Transcoder temporary directory and set your USB external drive's mount path (e.g. /mnt/usbstorage not /dev/sda1)

Scroll down further and hit Save Changes

I plan to create a Raspberry Pi 2 cluster to see if transcoding improves with 2 working together.

Now that you have completed the Install Plex Media Server on Raspberry Pi 2 guide you can configure Plex Media Server

Plex Raspberry Pi 2 Images

There is a ready made image for the Raspberry Pi 2 that are regularly updated, share the post to reveal the links. Update Plex by running sudo apt-get update && sudo apt-get upgrade -y .

If you cannot see the unlocker whitelist this site in AdBlock 😉



For the Plex Media Server image, login with root, password htpcguides and use raspi-config to expand the file system, it does not include WiFi drivers yet but you can install them

apt-get install firmware-linux-nonfree -y

Enjoy Plex on your Raspberry Pi 2 🙂
