Not sure what happened in the past few days but my hpool-miner stopped at least two or three times. I only caught it when I checked the hpool main website. Upon looking at the logs there was nothing so I decided it’s the time to create an hpool-miner service that would auto start and restart the service so I would not need to worry about these kind of things any longer. As always I will try to make it easy for anyone, not too familiar with Linux, in case you have any questions, feel free to ask.
I use Rasbian 32 bit version, even though I have the 8 GB version. The reason to the 32 bit is because this is what the hpool dev team uses to test their code. As you may know a 32 bit Operating System cannot address larger than 4 GB memory space but that only applicable at the per processes level so I decided 32 bit is good for me. Rasbian is a variant of the Debian Linux distribution and it uses systemd – that is a Linux initialization system and service manager. In case you do this thing the first time I highly recommend you not to mess up with your current config so copy instead of moving or deleting the configurations. I would like to avoid being blamed that you got stuck and you cannot farm :).
Creation of the hpool-miner service
- Create the service file for hpool-miner
sudo vim /etc/systemd/system/hpool-miner@.service # I use vim to create/edit file, you can use something else
Description=HPool miner: %i
ExecStart=/opt/hpool-miner/hpool-chia-miner-linux-arm -config /home/%i/cfg/config.yaml
Without getting into the details, the important part is that it will try to start hpool-miner 5 times in case of a failure, wait 500 sec between the retries and obviously it would start it when your system starts. Few things that requires changes from your end:
- Create new user/group
- Move hpool-miner binary
- Create custom directory for the configuration
Let’s get into that part.
- Create a new user: You will have a new /home/hpool directroy and it will auto create hpool group too. This user does not need to have login access so you can exclude it from the sshd config file.
sudo adduser hpool
- Deny the new hpool user’s SSH access
and add the following line to the bottom of the file
- Restart SSH service
sudo systemctl restart ssh.service
- Move the hpool binary under /opt/hpool-miner
- Copy the binary
cp /from/where/your/miner/currently/is/hpool-chia-miner-linux-arm /opt/hpool-miner/
- Put the config file under the dedicated hpool user’s home directory
- Move the config file
cp /from/where/your/config.yaml/currently/is/config.yaml /opt/hpool-miner/
Edit config.yaml and change the logging path
I cheated here, I not only changed ‘path:’ but I also raised the logging level ‘lv’ to debug.
Add the systemd service and then start
sudo systemctl enable hpool-miner@hpool and then
sudo service hpool-miner@hpool start
user@farmer:~ $ systemctl status firstname.lastname@example.org
● email@example.com - HPool miner: hpool

Going forward hpool logs will be here (based on the config file you modified before):
- Checking service status:
corvin@farmer:/home/hpool/cfg $ systemctl list-units --type=service | grep hpool
firstname.lastname@example.org loaded active running HPool miner: hpool
systemctl status email@example.com
- In case the startup failed you may need to clear the failed status, you can do with:
sudo systemctl reset-failed
- Usually follow with:
sudo systemctl daemon-reload
If you need to disable the service then do
sudo systemctl disable hpool-miner@hpool.
Hope it will work for you! BTW this is not only relevant for hpool, you can use it for anything else for example for the official chia software as well.

This is the perfect site for anybody who would like to find out about this topic.
You realize so much its almost hard to argue with you (not that I really will need to…HaHa).
You definitely put a new spin on a subject that has been written about for a long time.
Great stuff, just excellent!
please post image for tutorial
Did you get stuck? Let me know and i’ll try to help.

I’m farming hpool using HIVEOS, tried crontab using @reboot sleep 60; cd /chia/linux/ ; ./hpool-miner-chia
hiveos always closes the terminal after the session.
in this tutorial of the topic i got stuck in the part and add the following line to the bottom of the file
any information helps me, thanks in advance.
I’m trying on hiveos
