XRP Node Deployment Guide

Introduction

Deploying an XRP node involves configuring rippled server software to operate in various modes, including Stock Server, Validator, or Standalone. This guide provides a step-by-step approach to hardware setup, installation, and optimization for different use cases.

Prerequisites

Recommended Hardware and Software Configuration

For optimal performance in production environments, ensure your server meets these specifications:

| Component | Requirement |
|------------------------|-----------------------------------------------------------------------------|
| Operating System | Ubuntu 16.04+ |
| CPU | Intel Xeon 3+ GHz (4 cores with hyper-threading) |
| Storage | SSD (supports 10,000+ IOPS) |
| RAM | 32GB (production), 8GB+ (testing) |
| Network | Gigabit interface with 2Mbps+ bandwidth |

Key Considerations:

• SSD Storage: Essential for handling high transaction volumes (7,000–10,000 IOPS).
• Network: Expect bursts up to 100Mbps during ledger synchronization.
• Storage Capacity: Allocate ~12GB/day for NuDB or ~8GB/day for RocksDB.

Installing rippled on Ubuntu

Steps:

1. Install Dependencies:

   sudo apt-get update  
   sudo apt-get install yum-utils alien  

2. Add Ripple Repository:

   sudo rpm -Uvh https://mirrors.ripple.com/ripple-repo-el7.rpm  

3. Download and Install rippled:

   yumdownloader --enablerepo=ripple-stable rippled  
   sudo alien -i --scripts rippled*.rpm  

4. Enable and Start Service:

   sudo systemctl enable rippled.service  
   sudo systemctl start rippled.service

Operational Modes

1. Stock Server Mode

Use Case:

• Trusted local node for API access and transaction signing.
• Acts as a public gateway for validator nodes.

Configuration:

• No additional setup required post-installation.

2. Validator Mode

Use Case:

• Participate in consensus by validating transactions.

Steps:

1. Generate a validation seed:

   rippled validation_create  

2. Update rippled.cfg with [validator_token] and cluster settings.

Cluster Deployment

Why Use Clusters?

• Shared Workload: Reduces redundant transaction verification.
• Enhanced Security: Mitigates DDoS risks by isolating validators behind stock servers.

Setup:

1. Configure [ips_fixed] in rippled.cfg with cluster member IPs.
2. Assign unique node_seed values per server.

[cluster_nodes]  
n9McNsnzzXQPbg96PEUrrQ6z3y...  # Public key of Server 1  
n94UE1ukbq6pfZY9j54sv2A1...    # Public key of Server 2  

Standalone Mode

Use Case:

• Testing transactions offline without network connectivity.

Commands:

rippled -a --start  # New genesis ledger  
rippled -a --load --ledger 19860944  # Load specific ledger  

FAQs

Q1: How do I update rippled?

A: Use:

sudo rpm -Uvh --replacepkgs https://mirrors.ripple.com/ripple-repo-el7.rpm  
yumdownloader --enablerepo=ripple-stable rippled  
sudo alien -i --scripts rippled*.rpm  

Q2: What’s the difference between NuDB and RocksDB?

A: NuDB is optimized for SSDs and uses fewer file handles, while RocksDB may require more memory.

Q3: How can I verify my validator domain?

A: Sign your domain with an SSL key and submit details via Ripple’s Google Form for inclusion in public lists.

Conclusion

Deploying an XRP node requires careful hardware selection, configuration tuning, and understanding of operational modes. Whether running a stock server, validator, or standalone node, ensure adherence to security best practices and network requirements.
