LiteDAG

Running as a Service

2 min read

Running LiteDAG with systemd

Run the node and staker as systemd services so they start on boot and restart on failure.

Node Service

Create /etc/systemd/system/litedag-node.service:

[Unit]
Description=LiteDAG Node
After=network-online.target
Wants=network-online.target

[Service]
Type=simple
User=<your-user>
WorkingDirectory=/path/to/litedag-blockchain
ExecStart=/path/to/litedag-blockchain/litedag-node \
    --data-dir /path/to/litedag-blockchain/data \
    --public-rpc
Restart=on-failure
RestartSec=5
StandardInput=null
StandardOutput=journal
StandardError=journal
SyslogIdentifier=litedag-node

[Install]
WantedBy=multi-user.target

To also mine, add --mine <your-wallet-address> to the ExecStart line.

Staker Service

The staker signs PoS blocks and earns 40% of block rewards. It requires a local node running.

Create /etc/systemd/system/litedag-staker.service:

[Unit]
Description=LiteDAG Staker
After=litedag-node.service
Requires=litedag-node.service

[Service]
Type=simple
User=<your-user>
WorkingDirectory=/path/to/litedag-blockchain
EnvironmentFile=/path/to/litedag-blockchain/.staker.env
ExecStart=/path/to/litedag-blockchain/litedag-wallet-cli \
    --open-wallet <wallet-name> \
    --wallet-password ${STAKER_PASSWORD} \
    --start-staking delegate<id> \
    --non-interactive
Restart=on-failure
RestartSec=10
StandardOutput=journal
StandardError=journal
SyslogIdentifier=litedag-staker

[Install]
WantedBy=multi-user.target

Create the password file:

echo "STAKER_PASSWORD=<your-password>" > /path/to/litedag-blockchain/.staker.env
chmod 600 /path/to/litedag-blockchain/.staker.env

Enable and Start

sudo systemctl daemon-reload
sudo systemctl enable litedag-node litedag-staker
sudo systemctl start litedag-node
sudo systemctl start litedag-staker

Useful Commands

sudo systemctl status litedag-node       # check node status
sudo systemctl status litedag-staker     # check staker status
sudo journalctl -u litedag-node -f       # follow node logs
sudo journalctl -u litedag-staker -f     # follow staker logs
sudo systemctl restart litedag-node      # restart node (staker restarts too)
