Aaaand, first failure!!

After installing rustup, using cargo to download+compile lemmy server, and configuring lemmy, when I try to execute lemmy-server it fails. After enabling the backtrace, this is what I get:

./lemmy_server

These variables are probably relevant:
CARGO_HOME=/usr/local/cargo
RUSTUP_HOME=/usr/local/rustup
PATH=/usr/local/cargo/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
RUST_BACKTRACE=full\

(Side note, the "code" and "quote" functions of the forum are cranky to say the least)

Any suggestion would be greatly appreciated.

Hi again!

After the long holidays, here I am again

My server is starting to take shape. Apache is already working, the 2 needed hostnames are online, and the certificates are configured (certbot). PostgreSQL is also already working correctly. This week I'll attempt installing Lemmy and then LemmyBB, but I'm already having some doubts about the configuration of Lemmy, in particular here:

the domain name of your instance (mandatory)
hostname: "unset"
Address where lemmy should listen for incoming requests
bind: "0.0.0.0"
Port where lemmy should listen for incoming requests
port: 8536
Whether the site is available over TLS. Needs to be true for federation to work.
tls_enabled: true

For the hostname, I'm assuming it's the public FQDN.
The bind can be 127.0.01, as Apache will reverse proxy it?
Port is clear.
As the reverse proxy (Apache) is the one who is going to be handling the actual TLS, should TLS be enabled here? As I don't see any way of configuring the certificate into Lemmy, is this a way of telling Lemmy that the reverse has TLS enabled? If Lemmy needs the actual certificate (how?), can it be pointed to the same key file that certbot generates for Apache, so as to simplify it's renewal?

Many thanks!!

Well, after nutomic comments, and after reading the Lemmy docs in depth, I'm going with the manual installation I'll report back when I have something working, after all the holidays pan out.

Happy new year!

Where did you read the command mkdir /srv/lemmybb?

Here: https://github.com/LemmyNet/lemmyBB#installation

Yes and no The database is running in a Docker container, but the database files are located outside the container volumes/postgres

Understood. The question is, can this instance of Postgres be accesed from another application? I'll investigate further.

yes it is possible to do the reverse proxy with apache but as far as I know nginx is more performant and easier to set up

As I said, I have zero experience with Nginx, and lots of experience with Apache. As exposing a service to the internet can be dangerous, I'm more comfortable with my knowledge about securing Apache.

the hardware requirements depend on what you want to achieve, an instance with 10k users? then neither the hardware nor the bandwidth will be sufficient.

I have no goal in mind, if in the future it grows a lot, I can always migrate to a bigger setup. My concern is not meeting even the bare minimum.

Which question has now had to do with lemmybb, it was here only about lemmy backend

Sorry, I'm not sure what you are trying to convey here.
