Using Node.sh (deprecated)

1. Stop Systemd Service

sudo service harmony stop

2. Backup Files

Create a folder called "backup" in case it does not exist:

mkdir -p backup

Backup both node.sh and harmony binary file:

cp {node.sh,harmony} backup

3. Download Node.sh

Before we proceed to next steps we need to download the necessary files:

curl -LO https://harmony.one/node.sh && chmod +x node.sh
./node.sh -d && mv staging/* ./

curl -LO https://harmony.one/node.sh && chmod +x node.sh
./node.sh -d -N testnet && mv staging/* ./

Check the Binary CLI and node.sh version that was downloaded:

./harmony -V
./node.sh -v

4. Restart Systemd Service

sudo service harmony restart
