I tried installing Lemmy on my server, but it runs Apache HTTPD on the web port, and I couldn’t work out how to integrate Lemmy with that web server. From what I can tell from the NGINX sample config, you need to be able to specify rewrite rules based on the HTTP request method rather than on just the URL, and I just couldn’t see how to do that with Apache…
I think I’ll try installing kbin instead, this seems to have a more standard setup, similar to Mastodon.
In the Lemmy documentation they clearly say they don’t want to support any reverse proxy except nginx, so not really much point posting it to any “official” community.
