Private Servers Deployment

This guide walks you through connecting and deploying blockchain node to your private server on Blockops.

Prerequisites

• Ensure that SSH server is running on your device.

• If your SSH server runs on a non-default port (not 22), update the SSH port in the Blockops UI to match.

• Ensure your deployment user does not require a password for sudo commands.

  • You have two options:

    1. Create a dedicated passwordless user for Blockops.

    2. Allow passwordless sudo for your user by editing the sudoers file:

       sudo visudo

       Add this line (replace youruser with your actual username):

       youruser ALL=(ALL) NOPASSWD:ALL

Authentication Methods

1. Password-Based SSH Authentication: you'll need:

   1. username: the username on your device

   2. password: the password for that user

   3. port: the SSH port (default: 22)

2. Private Key Authentication

Blockops does not support passphrased private keys.

1. Create a new SSH key pair: run this command on your terminal

   ssh-keygen -t rsa -b 4096 -C "[email protected]"

2. When prompted:

   1. File path: Press Enter to save to default (~/.ssh/id_rsa)

   2. Passphrase: Press Enter to create a key without a passphrase

3. Add the public key Copy the contents of ~/.ssh/id_rsa.pub into ~/.ssh/authorized_keys

Connecting Your Private Server to Blockops

Log in

• Go to app.blockops.network

• Sign in or create an account

Select deployment options

1. Choose the network you want to deploy

2. Select Baremetal as the cloud provider

3. In the Authentication section, check the private server field and follow the on-screen instructions.

Install Autossh

On your private server, install autossh:

MacOS

brew install autossh

Ubuntu/Debian

sudo apt update && sudo apt install -y autossh

Establish the SSH Tunnel

Run this command once (to add blockops.sh:7777 to known_hosts):

You can find this command in the Authentication section after selecting the Private Server option.

sudo autossh -M 0 -R example71:22:localhost:22 blockops.sh -p 7777

Then, re-run the same command to establish the persistent connection

sudo autossh -M 0 -R example71:22:localhost:22 blockops.sh -p 7777

This creates a private, secure tunnel between your server and Blockops.

Deploy Your Node

Return to the Blockops UI and click Continue to finalize the connection and deploy your node.
