Run as a service

[gunar]

Hi,

How can I set up the snap packge to start bitcoind automatically? I'm having trouble running bitcoin-core.daemon as a service on CentOS. It seems snap (i.e. SELinux) won't let systemd read the binary file bitcoin-daemon that lives inside the snap container. Please find logs and service file below. Any help is greatly appreciated.

Also, I've just learned there's a thing called a "snap services" (docs). Perhaps that'd be the best way to move forward? In that case, perhaps we should consider adding a service configuration to this repo?

Thanks in advance.

journalctl -xe

/etc/systemd/system/bitcoind.service

Did you get this figured out? I am currently running into this problem, running the snap as a service.

I think the snaps aren't made correctly, but this is just a guess: Snap Service Management Docs

I expected a "snap services" output showing bitcoin-core, but it's not there in spite of "snap list" showing bitcoin-core as installed. To me this means there is no service support with snaps. I hope I'm wrong :)

I have the same question. It's weird that no answer was given for such popular topic.

I ended up just using Umbrel in a VM, which also has built in Tor.

Nope, I've moved to https://github.com/fort-nix/nix-bitcoin

I don't think any of the people who work on Bitcoin Core use snaps or are particularly familiar with them. While we provide a snap as a courtesy, they are not particularly well maintained and doing anything more advanced than simply making the binaries available to be run is unlikely to happen. #225 is an attempt at making a snap service, but it may not work as I also do not use snaps nor am I well versed in how they work.
