How to Install Plex on a Synology NAS with DSM 7

A Guide to Installing Plex Media Server on your Synology NAS with the DSM 7

If you have been looking at buying a NAS drive for Plex to use as your own private Netflix, then there is a very good chance that you have heard the name ‘Synology’. They are the brand that produces some of the most user-friendly, yet powerfully efficient (yes, that is a thing!) servers in the market in 2022 and are often a highly recommended choice for setting up a slick, polished media streaming solution that uses YOUR movies/boxsets. Last year, Synology updated its system software and services platform, Diskstation Manager, from version 6.2 to 7.0 and improved a number of the system’s abilities and processes. However, the process for installing Plex media server on your Synology NAS changed, with DSM changing access privileges and defaults for 3rd party programs in order to ensure their solutions were as secure as possible. If you are running a Synology NAS drive with DSM 6.2 and are wondering how to install Plex Media Server, it is still remarkably straight forward and a full video walkthrough guide on this can be found HERE. However, those of you who have the most recent DSM7 upgrade (with DSM 7.01 and 7.1 already rolling out over 2022 gradually) will have found that the process for installing Plex has changed noticeably. So, today I wanted to walk you through, step by step, how to install Plex on a DSM 7 Synology NAS from beginning to end and ensure you get it right, first time. Alternatively, there is a video at the bottom of the page that will walk you through even quicker. Thanks for reading and I hope you enjoy this guide.

Plex Installation Guide on the DSM 7.0

Installing Plex on a NAS with DSM 7.0 is actually VERY similar to that of installing it on a DSM 6.2 Synology NAS, however, there are a few small changes in the process which allow Plex Media Server to access the correct directories. Previously these steps might be needed by most people but were not directed by the application especially clearly, so having these steps integrated into the formal setup is actually quite a smart idea by Synology. Let’s begin:

Step 1 – Head To The App Center

Step 2 – Go to the Beta Section

Step 3 – Find Plex Media Server and select Join Beta

Step 4 – Install Beta Application (speed depends on Internet Connection)

Step 5 – Select the location of where the Log Files will be installed – Can be left blank and it will save to the default directory

Step 6 – (This is the NEW bit) Give the Plex Media Server Application Permission to access the media directories. Head to the Control Panel

Step 7 – Then ‘Shared Folders’

Step 8 – Select the Folder where your Media is located in. In my case it is DS220PLUSSHARE – But it will be different on your own NAS device and based on your own storage setup

Step 9 – Select EDIT (at the top)

Step 10 – Then select the Permissions Tab

Step 11 – If Plex has created a local User (likely in DSM 6.2 . DSM 6 7.0 migration setups), make sure that the PLEX user account still has Read and/or Read/Write Access in the tick box list

Step 12 – Then (IMPORTANT) Select the drop-down menu at the top and switch to ‘System Internal’

Step 13 – Scroll down to the ‘Plex’ entry and give it Read and Write Access, then save the changes

Step 14 – Head back into the App Center window and click OK on the Plex Media App install setup window

Step 15 – The Plex Media APP should be installed and you can go ahead and click OPEN in the App Center window OR open it from the main Synology App dashboard

Step 16 – As this is a reinstallation of Plex Media Server on a NAS system as far as the Plex NAS app is concerned, the system may require PLEX to ‘claim’ the NAS once again, just head into the individual Server Settings and an option to CLAIM the server will appear in orange

Step 17 – Whether this is your first Plex Installation OR a DSM migration, you will likely need to establish the pathways for each multimedia file type.

Step 18 – Just head upto the ADD LIBRARY option and a popup will appear that allows you to select each Media Type

Step 19 – Then browse the directories (that you gave the Plex Media Application permission to access) and add the media that is appropriate

Step 20 – Now the Plex Media Server Application will scrape all the metadata from the site librarys (rotten tomatoes, IMDB, etc) and fill out all the slick PLEX GUI for your connected clients to enjoy.

And there you have it. Plex is now installed on your DSM 7 equipped NAS System. Here is a video that will guide you through the process if you prefer visuals over text!

    102 thoughts on “How to Install Plex on a Synology NAS with DSM 7

    1. My 2 cents on the video and people’s comments:
      1: If running DSM 7.xx I suggest downloading from Synology and using that file. Three attempts with the doing from the Package Installation were a failure. It never made the “Plex xxx xxx xx” shared folder
      2: To remove a PLEX installation, it is not complicated, right click on it and select “uninstall” (not sure exactly what it says but you get the point I am not doing a tutorial……and I figured it out myself
      3: I would love it to see a video from start to finish with the exact system that I have. But that really is not practical for many people that post things to help us out. If you trying to set up a NAS, you should have at least enough knowledge to handle simple troubleshooting. If you need to be handheld, I do not think a NAS for PLEX is for you.
      4: The OP’s vids are very good. I really enjoy them. But I do not rely on them for 100 percent of any solution. When I got my NAS and PLEX setup, I used several references to help me with it.
      5: I do wish that NASCompares would respond to the questions asked. I think it is fair that you give answers back to the most common questions asked. I do understand that more complicated or “one offs” would be best dealt with offline
      6: Comments like “I’m so tired of people putting setup tutorial videos together where they are working with an already existing environment and their directions don’t line up with someone who is starting out fresh.” sort of bug me.

      I get the frustration..I really do. But a weekend of working through a problem makes you smarter. I followed this video and I had problems. But I researched and figured them out. Also, Everyones’ environment is different!

      Negatives: I do feel that NASCompares does not really care about answering the most common basic questions. I think you guys make money from it (cool, lots of work you have to do) but you do leave people hanging. You are more of a TV show than a social media platform where ideas are shared and solutions found…which means you are part of those solutions. Shame on NASCompares for not offering help on the questions that pertain to the video that you posted that you make a profit off of.

      You started the video, at least support your followers.

    2. Excellent guide….but what if I’m migrating an existing Plex Set-up from a DS412+ to a DS920+? How do I make sure everything like playlistes etc are ported? Thank you.

    4. Thanks for sharing this detailed information! I would add a suggestion to warn folks doing this to ensure their VPN is off, I struggled for an hour trying to get Plex server set up because my VPN was active.

    5. so this nas box runs 24/7 to provide power/bandwidth to stream media by requests from remote devices like smartphones, laptops? (of course those devices sign in same account)

    6. What would you say is a reasonable priced NAS purely for playing 4K HDR media to my PLEX app on my TV (LG GX).

      Could i get away with roughly £300 for say 4TB

      Just now i am running off of a seagate 2TB 3.1 USB external HDD and it’s almost full along with my SSD on my PC so i am trying to decide whether to go with a NAS or just get another USB HDD. A NAS set up looks like it would be the best future proofing way to go with no cables hanging off my laptop lol

      It would be only for one TV

      I have a 5G wi-fi 6 set up on both the router and my laptop. The TV is connected to the 5G channel also.

      The NAS would only ever be used for PLEX and nothing else.

      The Ryzon 5 on my laptop handles 4K HDR and DV HEVC MKV file streaming to my TV so i am guessing i wouldn’t need a hi powered NAS, right?

      The only thing i have ever had struggle was Game of Thrones which was HEVC but i have a Series X and i streamed from the laptop to that then through the HDMI to the TV and that worked no problem. The weird thing is i have Dune Part one which is the same format as the GOT files and it plays fine with no transcoding.

    7. The way that you are mapping the drive, are you logging in with admin account? Would you want to create a different account with access to the mapped drive or would using the Plex account be a better option?
      REPLY ON YOUTUBE

    8. Please help

      I just changed my password like the email from plex said to do and I had it to log out all shared users

      Now I am getting an error message saying that my server is unavailable and I don’t know how to fix it. I logged out and logged back in. I Uninstalled the program and reinstalled a newer version and still it will not allow me access to my server

      Please help

    9. eventhough I installed the plex beta on my NAS I am not getting the plex folder under Shared folder. I all ready gave admin and my account permission, etc. Don’t know what Im missing.
      REPLY ON YOUTUBE

    10. What’s the point really of having a Plex server in your NAS? It makes the NAS cost more and it takes up CPU.
      Wouldn’t it be better to just have the Plex server be a separate dedicated cheap, or old computer on the network.
      REPLY ON YOUTUBE

    11. DO NOT install the beta. Just do download the Synology (DSM 7) file from Synology and manually install the package… then continue follow the instructions to add permissions to the folder etc… If you want to keep Plex updated, just download a new DSM 7 package from Plex, then manual install again and it will upgrade for you (there is no upgrade option in Synology Package Center but a manual install again will perform an upgrade – I tested and confirm this). You can also delete and keep settings option, and re-install a previous version if you every have a situation where a Plex update breaks something. Also HW acceleration works fine on my DS1520+ and no need to do any edits or docker workarounds… I think Plex has fixed a lot of the issues since these videos came out.

    12. Apart from Plex being a “one stop shop” is there any fundamental reason why you’d say use Plex Media server for music instead of say the built in iTunes Server software?

    13. Hey there, I followed your directions to a T. However, no matter how many times I uninstall to start over, I never ever get the window that says “How Plex Works”. So, everytime I go into Plex to add media, it takes me to a screen that says, “Install Plex Media Server. I have the Synology 920+.

My plex video quality is damn bad when I’m out of my home network and I read online that I’ll need to enable Remote Access. The issue is I just can’t get it to work! Do you have a step by step tutorial to resolve this issue?

    17. Doesn’t work for me. I created the Volume and the subdirectories. But in Plex i can’t see any directories beneath the PLEX directory. UPDATE: Had to allow access for PLEX system user

    18. Im having a problem With permissions showing up for plex. There is no new user for plex so I cannot add permissions to it and it causes my plex server to not be able to read the files. Do you know how I can resolve this?

    19. I´ve just set up my new Synology DS 920+ NAS and wanted to install also Plex on my NAS. For some reason, there will not be created a Plex user, so I can´t give the necessary acces for Plex to see my media. Does somebody know why?

    20. I got the “No soup for you!” when I open plex ????

      I feel that the path for the Plex app might be wrong.
      I wrote: “/volume2/plex_amp”

      I followed all the permissions + system internal user permissions

      volume1 is for time machine
      volume2 is for my apps
      volume3 is for all data like music & videos

    21. How best to setup up tv show folders? Is it okay to use, for example, SHOW TITLE, as the containing folder, then inside that folder, put SEASON1, then inside that folder, list the video files as EPISODE 1, Episode 2, Episode X, with or without titles since PLEX will ferret out that info from the net?
      REPLY ON YOUTUBE

    22. When I open Plex Media Server for the first time, it doesn’t take me to the screen “How Plex Works” Instead it takes me to “No Soup for You. You do not have accesss to this server.” Can anyone help?
      REPLY ON YOUTUBE

    23. Plex does not like to look too deeply through layers of folders, so create your file system in advance and make sure all your files are named in a way that Plex can read. It’s pretty clever but when it gets it wong, ot gets it completely wrong

      REPLY ON YOUTUBE

    28. Is there any reason to not place media files in a sub-directory under the Plex directory? Then there would not be a need to go back and grant access to the media directory since security rights would have already been granted at the Plex directory level, I would like to know the answer to this before I set up my new DS920+ arriving tomorrow. Thank you!

    29. Ya this video is confusing. You created a new shared folder called “Plex” in the beginning of the video. But then said a new folder will automatically be created also called “Plex” later in the video. Very confused on all of this. Nothing is working for me at all

    32. Does Synology or any HDD mfg releasing any notes on high capacity storage compatibility list yet. A friend had encountered issue with WD 18tb ultra 550 drive which is not working with error health info not available though it shows the available space to be initialized. Based on forum Intel based DS series seems be working with 18tb from both brands of Seagate and WD but none claim on non intel realtek chipset. Even support neither saying incompatible but keep insisting to check the drive by connecting to pc for health info.

    35. Hey, new sub here as I’m in the market for my first NAS and pretty much decided on the Qnap 453 (thanks to your videos) but when I put it into my cart Amazon “suggested” I look at the 473. This product is about $300 more but with that money you get the Ryzen and the max memory is substantially more, so I’m wondering why in all of your comparison videos you don’t compare these two? You typically only compare models that are the same price. But you’re missing out on a key part of your audience who (like me) don’t mind spending a little more as long as you explain the benefit of it; so many people choose a budget that tops out at $1k so maybe you could explain the advantages of spending just a little more money to step up to the much more expandable 473?

    38. I have Plex running on a WD My Cloud Mirror and just a DS920+ with DSM 7 in the packages Plex is listed under the Beta Packages.. I downloaded the newer version on the PLEX site however it was acting really weird (as in having a double image on top of one another the menu’s and media images) uninstalled PLEX and now going to the Beta version in the Package center. Set up is different than you have on the Video think a lot has been updated in the last two years. hopefully, the beta version works once it downloads to the control panel.
      Anyone have any suggestions on transferring my files(midea) from the WD mycloud mirror to the Synology DS920+ Thank you for the tour

I know N300 is specifically for NAS but many reviews say it’s very noisy. X300 isn’t NAS specific drive BUT at our work they use them in DS220J, that’s used for weekly backups.

    44. Thank you so much for this video. I don’t have a Synology nas but really wish I did. I have a Netgear nr 212. It’s not as intuitive as a Synology. My Netgear leaves a great deal of unanswered questions on Plex setup. I’ve been battling with this for 5 years and Plex is still not working smoothly, so I watch your videos and try to use any information you offer that I might apply to my situation. I so wish you would put together a “how to” for Netgear users. All the “how to” videos for Plex installs are mainly for Synology or some other nas brand, but never have I seen one for Netgear. Thanks again for your help and insight.
