Proxmox VE allows you to efficiently manage multiple virtual machines (VMs) on your dedicated server, making it ideal for running various blockchain nodes. This guide will walk you through the process of setting up a Proxmox environment and deploying multiple blockchain nodes as VMs.

Prerequisites:

• Dedicated server with administrative access. Bacloud offers dedicated servers with Proxmox virtualization installed. Select a Single CPU or Dual CPU dedicated server from a list, or contact Sales team to get a perfect server configuration following your needs.
• Downloaded Proxmox VE ISO image (https://www.proxmox.com/en/downloads/proxmox-virtual-environment/iso)
• USB drive (at least 1GB)
• Knowledge of specific blockchain node installation and configuration procedures (varies for each blockchain)

Part 1: Install Proxmox VE

1. Create Bootable Media: Use Etcher or Rufus to create a bootable USB drive with the downloaded Proxmox VE ISO image.
2. Boot from USB: Configure your server's BIOS/UEFI to boot from the USB drive.
3. Install Proxmox VE: Follow the on-screen instructions during the boot process. Choose your desired storage options, configure network settings, and set a strong root password.
4. Web Interface Access: Upon reboot, access the Proxmox VE web interface at https://<your_server_ip_address>:8006 using the root password you set.

Part 2: Setting Up a Blockchain Node VM

1. Create a VM: Navigate to "Datacenter" in the Proxmox interface and click "Create VM." Assign a name, select the desired operating system for your blockchain node (e.g., Ubuntu), and choose appropriate hardware resources (CPU, RAM, storage).
2. Install Guest OS: Boot the VM and follow the installation process for your chosen operating system.
3. Configure Network: Ensure the VM has network connectivity within your server's network.
4. Install Blockchain Node Software: Access the VM through a remote desktop tool or SSH and install the specific blockchain node software for your chosen network (refer to the blockchain's documentation for installation instructions).
5. Configure Blockchain Node: Follow the blockchain's documentation to configure the node, including setting up data directories, syncing the blockchain, and specifying network settings (ports, peers, etc.).

Part 3: Deploying Additional Blockchain Nodes

1. Clone the VM: You can easily create additional blockchain node VMs by cloning the initial VM you configured. This saves time by replicating the base operating system and configuration.
2. Assign Unique IDs: After cloning, ensure each node has a unique identifier within the blockchain network (refer to specific blockchain documentation). This might involve modifying configuration files within the VM.
3. Repeat Node Configuration: Access each cloned VM and follow the blockchain's specific instructions to configure them as individual nodes on the network.

Important Considerations:

• Resource Allocation: Carefully allocate CPU, RAM, and storage resources to each VM based on the specific blockchain node's requirements. Monitor resource usage and adjust configurations as needed to ensure optimal performance.
• Security: Implement strong security measures on both the Proxmox host and individual VMs. This includes firewalls, access control, and keeping software updated.
• Network Configuration: Ensure proper firewall rules are in place to allow necessary network traffic for each blockchain node. Consult your hosting provider's documentation if applicable.
• Blockchain Specifics: Each blockchain network has its own installation and configuration processes. Refer to the official documentation for detailed instructions tailored to your chosen blockchain.

Additional Resources:

• Proxmox VE Documentation: https://pve.proxmox.com/pve-docs/
• Resources for Specific Blockchain Nodes (vary depending on chosen blockchain)

By following these steps and consulting the specific blockchain documentation, you can leverage Proxmox VE to efficiently manage and operate multiple blockchain nodes on your dedicated server. Remember, security and resource management are crucial aspects of running multiple nodes effectively.
