Run a Sui Node using Systemd

Tested using:

  • Ubuntu 20.04 (linux/amd64) on bare metal
  • Ubuntu 22.04 (linux/amd64) on bare metal

Prerequisites and Setup

  1. Add a sui user and the /opt/sui directories
sudo useradd sui
sudo mkdir -p /opt/sui/bin
sudo mkdir -p /opt/sui/config
sudo mkdir -p /opt/sui/db
sudo mkdir -p /opt/sui/key-pairs
sudo chown -R sui:sui /opt/sui
  1. Install the Sui Node (sui-node) binary, two options:
  • Pre-built binary stored in Amazon S3:
wget https://releases.sui.io/$SUI_SHA/sui-node
chmod +x sui-node
sudo mv sui-node /opt/sui/bin
  • Build from source:
git clone https://github.com/MystenLabs/sui.git && cd sui
git checkout $SUI_SHA
cargo build --release --bin sui-node
mv ./target/release/sui-node /opt/sui/bin/sui-node
  1. Copy your key-pairs into /opt/sui/key-pairs/

If generated during the Genesis ceremony these will be at SuiExternal.git/sui-testnet-wave3/genesis/key-pairs/

Make sure when you copy them they retain sui user permissions. To be safe you can re-run: sudo chown -R sui:sui /opt/sui

  1. Update the node configuration file and place it in the /opt/sui/config/ directory.

Add the paths to your private keys to validator.yaml. If you chose to put them in /opt/sui/key-pairs, you can use the following example:

protocol-key-pair: 
  path: /opt/sui/key-pairs/protocol.key
worker-key-pair: 
  path: /opt/sui/key-pairs/worker.key
network-key-pair: 
  path: /opt/sui/key-pairs/network.key

  1. Place genesis.blob in /opt/sui/config/ (should be available after the Genesis ceremony)

  2. Copy the sui-node systemd service unit file

File: sui-node.service

Copy the file to /etc/systemd/system/sui-node.service.

  1. Reload systemd with this new service unit file, run:
sudo systemctl daemon-reload
  1. Enable the new service with systemd
sudo systemctl enable sui-node.service

Connectivity

You may need to explicitly open the ports outlined in Sui for Node Operators for the required Sui Node connectivity.

Start the node

Start the Validator:

sudo systemctl start sui-node

Check that the node is up and running:

sudo systemctl status sui-node

Follow the logs with:

journalctl -u sui-node -f

Updates

When an update is required to the Sui Node software the following procedure can be used. It is highly unlikely that you will want to restart with a clean database.

  • assumes sui-node lives in /opt/sui/bin/
  • assumes systemd service is named sui-node
  • DO NOT delete the Sui databases
  1. Stop sui-node systemd service
sudo systemctl stop sui-node
  1. Fetch the new sui-node binary
wget https://releases.sui.io/${SUI_SHA}/sui-node
  1. Update and move the new binary:
chmod +x sui-node
sudo mv sui-node /opt/sui/bin/
  1. start sui-node systemd service
sudo systemctl start sui-node
