Node Installer

This repository contains an easy to use installer to run a Dusk node for our Nocturne testnet and our Lunare devnet. For more information on how to participate, see the node running guide on our wiki.

Prerequisites

• Ubuntu 22.04 LTS x64
• OpenSSL 3
• VPS

This installer is specifically built for Ubuntu 22.04 x64. It might work on older or newer versions.

Packages

The installer comes with the following packages:

• Rusk service
• Rusk wallet CLI

Folder layout

The configuration files, binaries, services and scripts can be found in /opt/dusk/.

The log files can be found in /var/log/rusk.log and /var/log/rusk-recovery.log.

Installation

ℹ️ To run the latest release of the Node Installer execute the following command:

curl --proto '=https' --tlsv1.2 -sSfL https://github.com/dusk-network/node-installer/releases/download/v0.3.5/node-installer.sh | sudo sh

By default, the installer runs the node for our Nocturne testnet. If you'd like to run a node for the Lunare devnet or mainnet, you can pass devnet or mainnet as an option during installation:

curl --proto '=https' --tlsv1.2 -sSfL https://github.com/dusk-network/node-installer/releases/download/v0.3.5/node-installer.sh | sudo sh -s devnet

⚠️ CAUTION To run the not release yet unstable version of the Node Installer execute the following command:

curl --proto '=https' --tlsv1.2 -sSfL https://raw.githubusercontent.com/dusk-network/node-installer/main/node-installer.sh | sudo sh

Configuration

The installer comes with sane defaults, only requiring minimal configuration. Before the Rusk service can be started, the CONSENSUS_KEYS and DUSK_CONSENSUS_KEYS_PASS need to be provided.

The CONSENSUS_KEYS can be either moved to /opt/dusk/conf/ from another system or generated on the node itself and moved there.

Set consensus keys

To generate the provisioner keys locally, run rusk-wallet and either create a new wallet or use a recovery phrase with rusk-wallet restore.

To generate and export the provisioner key-pair and put the .keys file in the right directory with the right name, copy the following command:

rusk-wallet export -d /opt/dusk/conf -n consensus.keys

Set consensus password

Run the following command and it will prompt you to enter the password for the consensus keys file:

sh /opt/dusk/bin/setup_consensus_pwd.sh

Reset Rusk state

To remove old Rusk state and the old wallet cache, simply run:

ruskreset

Start Rusk

Everything should be configured now and the node is ready to run. Use the following commands:

service rusk start

Check the status of the Rusk service by running:

service rusk status

Check the installer version

To check your installer version, run:

ruskquery version

If you're running an outdated version of the installer, it will warn you and ask you to upgrade.

Fast Syncing with Archival State Download

To significantly reduce the time required to sync your node to the latest published state, you can use the download_state command. This command stops your node and replaces its current state with the latest published state from one of Dusk's archival nodes.

To see the available published states, run:

download_state --list

Using the Fast Sync Command

1. Stop your node (if it's running):

   service rusk stop

2. Execute the fast sync command.

   download_state

   If you want to sync up with a specific state instead of the default one, you need to pass the block height of the state you want to syncup with.

   download_state 369876

   Follow the prompts to confirm the operation.

3. Restart your node:

   service rusk restart

This process will ensure your node is up-to-date with the latest blockchain state, allowing you to sync faster and get back to participating in the network in less time.

Note

If you are experiencing errors in downloading the state, it might be due to some remnants of previous state syncing. Try to clean up with sudo rm /tmp/state.tar.gz

Diagnostics

Check if your node is syncing, processing and accepting new blocks:

tail -F /var/log/rusk.log | grep "block accepted"

To check the latest block height:

ruskquery block-height
