Set the miner settings

POOL_URL="pool_url"
WALLET_ADDRESS="wallet_address"

Install dependencies

sudo apt-get update
sudo apt-get install -y opencl-headers ocl-icd-libopencl1 opencl-clhpp-headers
clinfo ocl-icd-opencl-dev

Clone and build the cgminer software

git clone https://github.com/ckolivas/cgminer.git
cd cgminer
./autogen.sh
./configure --enable-opencl
make

Get the maximum values for thread-concurrency, shaders, and worksize

MAX_THREAD_CONCURRENCY=$(clinfo | grep "Max compute units" | awk '{print $4}')
MAX_SHADERS=$(clinfo | grep "Max compute units" | awk '{print $4}')
MAX_WORKSIZE=$(clinfo | grep "Max work group size" | awk '{print $5}')

Create a config file with all desired settings

echo "scrypt
url=$POOL_URL
user=$WALLET_ADDRESS
pass=x
no-submit-stale
coinbase-addr=$WALLET_ADDRESS
fee=0
expiry=60
intensity=31
worksize=$MAX_WORKSIZE
thread-concurrency=$MAX_THREAD_CONCURRENCY
shaders=$MAX_SHADERS" > ~/.cgminer/cgminer.conf

Run the GPU miner in the background with the specified config file

nohup ./cgminer --config ~/.cgminer/cgminer.conf &

Create a system service to run the mining script on startup

echo "[Unit]
Description=Mining Service

[Service]

Type=simple
ExecStart=$(pwd)/start-mining.sh

[Install]

WantedBy=default.target" | sudo tee /etc/systemd/system/mining.service

Enable the mining service

sudo systemctl enable mining.service
