How to setup a Chia Harvester on Ubuntu

Posted on May 4, 2021

A Chia Harvest is a computer that farms Chia and connects back to a Master Node. You can almost think of it like the Master Node being a Pool and the harvesters as nodes on that “pool”. In this post we’ll talk about setting up a Chia Harvester on Ubuntu. Shouldn’t matter which version of Ubuntu. LTS or the latest should work fine.

Do note that we do not need the gui installed for this to work. Refer to this post to install Chia

Note: In the following commands we are assuming that the Chia directory is in your home “~/” directory on the harvester. Change the path if different.

Before we start you will need the ca directory from your Main/Master node uploaded or accessible to your Ubuntu harvester. You can get the CA directory from the following locations on Windows and Linux.

On Linux

~/.chia/mainnet/config/ssl/ca

On Windows

C:\User\username\.chia\mainnet\config\ssl\ca

You should be able to copy and paste the following path into Explorer to get to the correct directory.

%homepath%\.chia\mainnet\config\ssl\ca

Copy Chia ca directory

Copy this folder onto your Desktop, thumbdrive, network share, just some place you can access it.

Upload ca folder

You can use scp to upload the ca folder of the Harvester. In the following example we put the ca directory on our Windows desktop and we are uploading to our harvesters home directory.

scp -r Desktop\ca user@192.168.1.5:~/

Activate Chia

The rest of the commands are run on the harvester. You can either ssh or physically log into it. If Chia was installed in a different directory, then you will need to change the path.

cd chia-blockchain 
. ./activate

Configure Harvester

You should be able to copy and paste all the following commands in, change the parts in bold as needed.

The –set-farmer-peer option is your main node’s ip address.

chia init -c ~/ca

chia stop all

chia configure --set-farmer-peer 192.168.1.4:8447

chia configure --enable-upnp false

chia plots add -d /media/user/plotdrive/

chia start harvester -r

Should be all set. You can check the Main Node to verify that the harvester is connecting.

Important Notes:
UPNP needs to be turned off. It can cause problems if there are multiple wallets running on a local network that both have upnp on.

Add your plot drive locations. We need something to harvest :)

Verify that the Linux user can write to the Chia Plot drives

The following command will give the ubuntu user write access to the drive. Change the path to your drive.

sudo chmod ugo+wx /media/username/your_drive

Creating Plots

Create plots by specifying the Farmer Public Key and the Pool Public Key. You can get these from the Main Node. Plan on adding info on how to retrieve that info soon.

chia plots create -t /media/user/plotdrivetmp -d /media/user/plotdrive -f biglongublicfarmerkeyag934gh3bh3h4 -p biglongpoolpublickey129gmc2390243t-gg49
