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.
Why are you tagged as bot account?
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.
I moved all my live site config files out of /etc/nginx/sites-enabled
ran the
certbot certonly --nginxcommand from the 'From Scratch" instructions, which now prompted me for domain names interactively.put back my previous sites-enabled files I removed in step 1.
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
Thanks @RoundSparrow
I am able to bring things up and I can create an admin user by visiting the /setup URL.
Problem is, after I create my admin user, the /setup URL appears to still be active.
Is there some step I am missing to disable this /setup page after I have created my admin user?
There are security/data-exposure issues with this that I raised on Github… https://github.com/LemmyNet/lemmy/issues/3060 (I’m RocketDerp)
My testing shows that visiting /setup on Lemmy isn’t restricted. it behaves differently if you are logged-in or not logged-in. If not logged-in, it presents a form to create an admin user. If logged-in (even as a normal non-admin user) it shows the site configuration.
Since /setup has to be accessible to someone not logged-in, the whole design is a race condition for some script-kiddie to admin-create wen installing on a public remote server. The admin accounts should probably be managed from Linux shell and not from lemmy-ui
Ok, thanks for confirming that I am not entirely insane.
1 - I visited other lemmy instances and saw that the /setup URL was still accessible.
That seems like a huge bug / security issue.
2 - How did you configure and daemonize pictrs?
I don’t want to run that as root, so I ended up creating a pictrsxx user
And a
systemdservice that runs as that user./etc/systemd/system/lemmy-pictrsxx.serviceWhich makes me wonder, what is the purpose of this “embed-pictrs” option.
cargo install lemmy_server --target-dir /usr/bin/ --locked --features embed-pictrs3 - email
Still can’t get smtp to work.
The developers did respond and basically said that the config can be derived by federation and other aspects, so they don’t consider it a significant security risk. It doesn’t seem to allow writing of changes unless an admin, so I guess it is what it is for now. It is mentioned on Github and in the forums now, so others can raise the issue if they thing it is serious.
I actually didn’t bother setting up email, I’m trying to hack on the code and get some of the database tuning done and I thought there needs to be some better way to sign-up and notify new users. But I can try to help you, I do know a lot about email. I’ll warn you that spam filters probably won’t like Lemmy instances, email is a battleground with hosting providers.
I didn’t setup images, did that really run as root? I thought it would have been running under the lemmy user account, but I I don’t know.
Don’t be afraid to ping me if you need help.
They have fixed some of the install issues based on our feedback, co new server setups won’t be as difficult. And I do want to try and edit the documentation on ‘from scratch’ for them to make it more consistent (the lemmy_server I think should also be done from git checkout on a ‘from scratch’ and a few other changes in toe docs).
It probably does something to the code to enable the hand-off of the pictures, but doesn’t actually setup everything automatically. Not sure, just guessing.
