0xBitcoin Mining on HiveOS

0xbtc-hive.txt

#from hive console
stop all miners on rig
disable hashrate watchdog #don't want the last miner starting back up on it's own

#from terminal
ssh user@192.168.1.XXX  #the local ip of the rig

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9
sudo apt-get upgrade libstdc++6

#After that you can check if you get GLIBCXX desired version like this:
strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX
#if you see 'GLIBCXX_3.4.22' then proceed

cd /root
mkdir 0xbitcoin
cd 0xbitcoin
wget https://github.com/azlehria/0xbitcoin-gpuminer/releases/download/v2.10.0-pre5/0xbtcminer-linux_2.10.0-pre5.tar.xz.txz
tar xf 0xbtc*

sudo apt-get install npm
npm install -g cryptr

0xbitcoin-miner #launch the miner
account new #create a new account to initialize the keystore, won't mine to this account though
account select 0x263Ac803afECf644e97a858893e0a159EC6ca946 #change to your eth address
account list #verify the correct account is selected
pool select http://mine0xbtc.eu:8586 #vardiff
pool list #verify correct pool is listed
pool mine cuda #verify that mining starts

#you can stop now if you only have 1 gpu, proceed with tmux setup to run multiple gpus
ctrl-c ctrl-c #quit the miner

sudo apt-get install tmux

#### repeat with N from 0 to number of gpus-1 - eg 8 gpus, 0-7
tmux
CUDA_VISIBLE_DEVICES=N 0xbitcoin-miner
pool mine cuda
crtl-b d #detach leave the miner running

### should now be running on multiple GPUs

tmux list-sessions #view running sessions

#to attach back to a session
tmux attach -t 0 #attach to session 0


=======================
Limitations
* HiveOS console will not show hash rate, only gpu temp and fan speed - sufficent to tell if miner is still running
* 0xBitcoin miner will not auto-start if rig is restarted - rig will go back to last selected miner

Future Improvements
* shell script to config and launch miners - take number of gpus, address, pool url as params - config miner and launch 1 miner per gpu - tmux has 'send-keys' so it should be pretty doable
* Using the proxy from mine0xbtc.eu - one proxy per rig to avoid single point of failure
 - not sure if needed, i'm running 30 gpus across 4 rigs without it currently, seems OK, but i have quite fast internet here, maybe worse on slow connection
