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?

    Before I even get there, the instructions say I should be able to run

    curl localhost:8536/api/{version}/site

    And it should return some json structure.

    But I see this returning 404

    lemmy_server[41511]: 2023-06-09T17:02:35.296098Z  INFO actix_web::middleware::logger: 127.0.0.1 "GET /api/0.17.3/site HTTP/1.1" 404 0 "-" "curl/7.81.0" 0.000074

    Is that the correct way to specify the version?

    Is there a better log than journalctl which would actually tell me what REST endpoints it is using?

      Is that the correct was to specify the version?

      No, I had to dig around too, the correct command is:

      curl localhost:8536/api/v3/site

        Thank you, again!

        How was I to know {version} in the REST endpoint path was supposed to be “v3”?

        Any luck with the lemmy-ui install?

              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
