I have Mastodon running on a VPS running Debian 11. Now I would like to add a Lemmy instance on the same server. I tried using the from scratch method from Lemmy documentation, but ran into errors that likely stemmed from minor version incompatibilities of the dependencies. I tried using the Lemmy easy deploy script but it wants to bind all traffic on port 443 for Lemmy which would break my Mastodon install. Has anyone managed to get Lemmy and Mastodon running on the same box, and if so, can you share any details of your setup?
You need a reverse proxy like nginx or traefik. Your mastodon server is using the web ports. Lemmy also wants to use the same ports. Obviously the can’t both use them.
The solution is to let neither use the ports and set them up on some other ports.
The reverse proxy is then set up as your main “web server”. It will then look at every request coming in and based on the domain name or url requested redirect (or rather forward or proxy) the request to the correct service… mastadon or Lemmy.
I run dozens of services on the same server. And use traefik to sit in front and manage it all.
I have reverse proxy configured for Mastodo using Nginx. It’s the Lemmy Easy Deploy script trying to bind all traffic on port 443 where I run into problems.
Don’t use that silly script. Easiest is to use the docker compose method and modify the compose file to remove the nginx container since you already have nginx. Then once you have lemmy’s containers running, add config to nginx to point to the ports lemmy/lemmy ui listen on
Thanks for the tips! That sounds like a great approach. I’ll give it a shot.
This worked great! Thanks again for the advice! When the from scratch install didn’t work, multiple people suggested the easy deployment script. For my setup the Docker compose deployment was perfect and offered the opportunity for customization I needed. The easy deployment script does look pretty slick though if someone just wants a turnkey setup and wants to dedicate their whole box to it.
