So I’m in the process of moving my discord server over to matrix. I rented a VPS with 2 cores/2gb of ram for this. What I’m having issues with is media store and federation. I believe I have the media_store configured corrected as I can post images in my own channels, however I get Error 500 while attempting to upload a profile picture with no other information. On the federation side of things, I joined #matrix:matrix.org on my server it syncs for a few seconds, my ram shoots up to 2gb usage and hard locks until I restart synapse. Am I missing a config flag? Or just not enough RAM to federate with an instance that big. Thanks
It would be helpful if you could provide more information. Which setup? OS? Dockerinstall or bare metal? Did you follow a specific Guide? Link it please if you followed one.
With this you will get better answers 🌞
Ubuntu 22.04, bare metal. I followed this guide and the official docs as well as tweaked it for my needs. I posted my yaml in another comment as well
Check this out https://github.com/spantaleev/matrix-docker-ansible-deploy It should make the process a bit easier for you.
I haven’t played with ansible before but that looks like exactly what I want, thanks! I’ll spin up a VM on my dev server at home and play around with it
That’s very normal regarding the crash trying to join #matrix:matrix.org. You need much higher specs and need to be using Postgres database, MySQL probably won’t handle it.
Can you post a sanitized version of your homeserver.yaml so we can take a look at your config?
Also are you running docker or something else?
Heres my yaml. I quickly skimmed the docs and set it up last night so its probably pretty jank. So I guess my large channels issue is solved and I need better hardware. As for the the Error 500 I get while uploading profile pictures, this is the exact error I get:
Failed to save your profile MatrixError: [500] Internal server error (https://matrix.*.xyz/_matrix/media/r0/upload?filename=5db2-6c61-48eb-827c-f09ec246af71.png)
Your config looks good to me. I’m thinking you may have a permissions error with your media store folder. What permissions do you have set for it?
- I can post media in my rooms and that works just fine, it’s just trying to set a PFP throws that error which is confusing. I rolled out an ansible node last night on the advice of someone else here so I’m attempting the matrix ansible playbook to get going
Sorry I should have added more info. I am using Postgres, I’ll post my sanitized yaml when I get home from work. It is a bare metal install at the moment but I plan on moving over to docker once I have a good understanding of all the functions and documentation
Yes your RAM is likely insufficient to join larger old rooms like that. Matrix Synapse can be quite a resource hog under certain circumstances.
While your server most likely isn’t powerful enough to handle large rooms such as that one, if you would still like to try and get as much performance as possible you can look at this synapse documentation page
As others said, Synapse can sometimes be very resource-hungry. It might be worth giving a try to Conduit and Dendrite, which are alternative Matrix server implementations and especially Conduit seems to be focused to by lightweight. Although I do not have any personal experience with them and it seems that they are most likely a lot less mature than Synapse at the moment.
