V8 DKG Core Node installation

This page will guide you trough the V8 DKG Core Node installation process

The installation process involves interacting with the installer through the terminal. To proceed you should have all the required input ready, as they will be required by the installer.

  • Ubuntu 20.04 or 22.04 instance

  • Admin and operational keys and their private keys

  • Funds on the wallets

  • RPC endpoints

  • Firewall configured

1. How the installer works:

The provided installer is designed for installing the OriginTrail node on Ubuntu 20.04 LTS and 22.04 LTS distributions. It is also possible to install the OriginTrail node on other systems, but it would require modifications to the installer. If you have any such modifications in mind, we highly encourage your contributions. Please visit our GitHub for more information.

During the installation process, OriginTrail node installer will execute the following actions:

  • Check for the Ubuntu OS version compatibility

  • Install required Node.js version together with NPM

  • Deploy OriginTrail node directory and install all required modules

  • Configure and enable OriginTrail node service (as systemctl)

  • Configure your nodes .origintrail_noderc file based on the provided inputs:

    • Admin and operational keys,

    • Node shares token name and symbol

    • Operator fee (value between 0 - 100 based on your choice)

    • RPC endpoint

  • Install and enable MySQL service and create operationaldb for the node

  • Configure MySQL user password for the OriginTrail node operational database (based on your inputs)

  • Install and enable BlazeGraph service (Tripple store database)

  • Automatically deploy otnode-logger.service in order to pass logs to OriginTrail team

During the V8 DKG Core node installation process, installer will deploy

otnode-logger.service which will automatically stream the V8 DKG Core node logs to OriginTrail team for support/debug purposes. This service is a hard requirement for the incentivised testnet rewards.

To disable this service, execute the following commands on the server once the installation is finalized:

systemctl disable otnode-logger.service
systemctl stop otnode-logger.service

2. Download OriginTrail V8 DKG Core node installer:

Ensure that you're logged in as root. Then, execute the following command in order to download the installer and grant it executable access:

cd /root/ && curl -k -o v8_installer.sh https://raw.githubusercontent.com/OriginTrail/ot-node/v8/develop/installer/v8_installer.sh && chmod +x v8_installer.sh

3. Execute the installer by running:

./v8_installer.sh

Do not run the installer with "sudo".

4. Verify V8 DKG Core node installation:

If your installation has been successful, your node will show the “Node is up and running!” log as shown in the example image below:

Congratulations, your V8 DKG Core node is up and running!

Useful commands:

Starting your node: otnode-start or systecmtl start otnode

Stopping the node: otnode-stop or systecmtl stop otnode

Restarting the node: otnode-restart or systecmtl restart otnode

Showing node logs: otnode-logs or journalctl -u otnode --output cat -fn 100
