💻 Run node as a systemd service ​

The runner.sh script automatically downloads and installs the latest version of the Witnet node software (witnet-rust). It can also be used to update to the latest version, since it will keep all the block chain data and the configuration file in the hidden .witnet directory.

For Testnet 7.3 and greater, the configuration file needs to be customized with the public IP and port of the node, which must be set at the public_addr field in witnet.toml .

  • Install latest version of ca-certificates to download safely from GitHub:
bash
sudo apt install ca-certificates
sudo update-ca-certificates
  • Create the witnet user dedicated to running the node:
bash
sudo adduser witnet
  • Clone the project's GitHub repository into your home directory and enter it:
bash
cd
git clone https://github.com/witnet/witnet-operator-tools.git
cd witnet-operator-tools
  • Install latest version with the witnet user dedicated to running the node:
bash
sudo -u witnet ./systemd/runner.sh
  • Copy the witnet.service file into /lib/systemd/system/:
bash
sudo cp systemd/witnet.service /lib/systemd/system/witnet.service
  • Every time you change the witnet.service file, you need to reload the systemd daemon:
bash
sudo systemctl daemon-reload
  • Enable the service:
bash
sudo systemctl enable witnet.service
  • Start the service:
bash
sudo systemctl start witnet.service
  • See the logs of the service:
bash
journalctl -f -u witnet.service
  • When you want to restart the service:
bash
sudo systemctl restart witnet.service
