Run a node using a service

Setting up systemd for your collator


To prepare for setting up a systemd service for the OAK binary, you’ll need the following information:

  1. INSTALLATION_DIR: Directory where downloaded the oak-collator binary
  2. NODE_NAME: Custom identifier for your node
  3. DATA_DIR: Directory where you would like to store OAK blockchain data
  4. NODE_KEY: Key for running your collator
  5. USER: User that the service should run as
  6. GROUP: Group that the service should run as


Once you have prepared the required information, you can use the following service definition to run the OAK collator. On Debian based distributions, this file should be placed at /etc/systemd/system/oak-collator.service.

Description="OAK Collator"

ExecStart=INSTALLATION_DIR/oak-collator \
  --name=NODE_NAME \
  --base-path=DATA_DIR \
  --chain=turing \
  --node-key=NODE_KEY \
  --collator \
  --force-authoring \
  --execution=wasm \
  --state-cache-size=0 \
  -- \
  --execution=wasm \



After you have created the service definition, you can enable and start the service using systemctl:

systemctl enable oak-collator
systemctl start oak-collator


systemd will automatically start your collator when you restart your system or if the process is killed. Here are some other commands that might be useful while operating an OAK node.

  • journalctl -u oak-collator
    • View logs for the node. man journalctl for more filtering options.
  • systemctl restart oak-collator
    • Restart the collator service

Monitoring & Alerting

Since OAK is a Substrate-based project, you can use Node Exporter, Prometheus and Grafana to monitor your nodes. For more information, please follow this tutorial.
