Running miner as invisible service

[Blogshot]

Hello,

I'm trying to run this as part of a headless Debian setup. This requires to run this without any console interfaces or the like.

My "setup" is one bash script that invokes the miner:

#!/bin/bash

cd /root/coinhive/ && coin-hive <SITE_KEY> --threads 1 > miner.log

If I run the miner from command line it works fine. However, as soon as I try to start it as a service or background process, the miner terminates.

So far, I've tried:

1) nohup /root/coinhive/miner & Resulting in

TypeError: process.stdin.setRawMode is not a function
    at Object.<anonymous> (/usr/lib/node_modules/coin-hive/bin/coin-hive:182:15)
    at Module._compile (module.js:624:30)
    at Object.Module._extensions..js (module.js:635:10)
    at Module.load (module.js:545:32)
    at tryModuleLoad (module.js:508:12)
    at Function.Module._load (module.js:500:3)
    at Function.Module.runMain (module.js:665:10)
    at startup (bootstrap_node.js:187:16)
    at bootstrap_node.js:608:3

2)

/root/coinhive/miner &
bg
disown

Resulting in: Process starts in background, but halts/terminates as soon as I hit disown.

3) Crontab: @reboot /root/coinhive/miner & Resulting in: Miner not starting at all.

4) Ctrl + Z doesn't respond at all.

It seems to me that for the miner to work, there has to be some sort of terminal or window active. Please advise.

you can try screen command and detach once you have it running as you want. screen command

ctrl+a then d

You could use the miner programatically instead of using the CLI. That process.stdin.setRawMode is something from the CLI code, but that shouldn't happen if you use it like this

@cazala Thanks, I made a custom js-Script that can be invoked via node command. Seems to be working!

@Blogshot just to let you know, this has been fixed in version v1.9.1, so now you should be able to use the CLI without that process.stdin.setRawMode error
