Install from Scratch - Lemmy Documentation
join-lemmy.org

I’m trying this on Ubuntu 22.04 Rust’s cargo install seems to keep creating permission problems between what I have to install, compile and what gets published in the cargo “registry”, which causes issues at runtime when I run as lemmy:lemmy through systemctl.

If I run: cargo install lemmy_server --target-dir /usr/bin/ --locked --features embed-pictrs as a non-root user, I get permission denied issues with /usr/bin/.future-incompat-report.json and /usr/bin/release

If I run the build as a root user, and then manually copy the binaries to /usr/bin and chmod them to lemmy:lemmy, then try to run as lemmy:lemmy, it appears the binary is trying to access some “registry” files in /root/.cargo/registry (for which of course it does not have permissions.)

How do I fix this?

    I knew it was v3 because I saw a webapp failure on one of the Lemmy instance (lemmy.ml) I was using ;) We need to update those install documents.

    It seems right now I can get a client to load, but websockets aren’t working. Others on Reddit reported the same issue: https://old.reddit.com/r/Lemmy/comments/142sszq/spinning_up_lemmy_websockets_dont_connect/

    EDIT: Ok, I solved the websocket problem by using proper nginx config that the instructions said. I was confused about the domain names with the certification generation as I already had some nginx certs for other subdomains in place.

        Oops. I was running some test code that IIRC set the bot field (it was code for creating a bot) on my own login. I just changed it. Thanks for letting me know.

          Well, you are the only person really responding to me here with helpful information.

          So if you are a bot, I welcome our new robot overlords.

          I’m still trying to get the lemmy-ui installed. I’ll check your links. Looks like they updated the join-lemmy.org page.

          I owe you a beer, or a pint of 10w-40.

            ha.

            I didn’t have much trouble with lemmu-ui, I ended up following instructions that put it at /var/lib/lemmy-ui on Ubuntu 22.04 server.

            I already had nginx running for a different domain name on that server, so that confused me for a while. As the SSL certification instructions assume you have an empty nginx server, it won’t prompt you for domain names if you already have some defined. Once I figured that out, the instructions worked fine.

            1. I moved all my live site config files out of /etc/nginx/sites-enabled

            2. ran the certbot certonly --nginx command from the 'From Scratch" instructions, which now prompted me for domain names interactively.

            3. put back my previous sites-enabled files I removed in step 1.

            4. Then the template in the ‘From Scratch’ instructions worked fine after the sed commands to modify it: https://raw.githubusercontent.com/LemmyNet/lemmy-ansible/main/templates/nginx.conf

            Are you stuck on updating NodeJS on your server? I already had Node apps on my server, so I followed my standard setup for node. I’m running lemmy-ui on Node.js v19.4.0, I think it probably wold work on version 20.x too. My npm --version says 9.3.1 and my yarn --version says 1.22.19
