Besu Nodes

Common Packages (All Besu Node Types)

openjdk-17-jdk      # Java 17 Runtime (Required for Besu)
wget                # Download Besu binary
curl                # HTTP client utilities
jq                  # JSON processing
netcat-openbsd      # Network utilities (nc command)
iproute2            # Network routing utilities (ip command)
iptables            # Firewall management
ca-certificates     # SSL certificate store
gnupg               # GPG for package verification
lsb-release         # LSB release information

Note: nginx for RPC Nodes

nginx is NOT installed on RPC nodes. Instead, VMID 105 (nginx-proxy-manager) is used as a centralized reverse proxy and load balancer for all RPC endpoints. This provides:

• Centralized management via web UI
• Load balancing across RPC nodes (2500-2502)
• SSL termination
• High availability with automatic failover

See docs/NGINX_ARCHITECTURE_RPC.md for details.

Install Scripts:

• install/besu-validator-install.sh
• install/besu-sentry-install.sh
• install/besu-rpc-install.sh

Verification Commands

After deployment, verify packages are installed:

# Check Java (Besu nodes)
pct exec <vmid> -- java -version

# Check Docker (Docker-based services)
pct exec <vmid> -- docker --version
pct exec <vmid> -- docker-compose --version

# Check Python (Python services)
pct exec <vmid> -- python3 --version
pct exec <vmid> -- pip3 --version

# Check specific packages
pct exec <vmid> -- dpkg -l | grep -E "openjdk-17|docker|python3"

Package Installation Notes

Automatic Installation

All packages are automatically installed by their respective install scripts during container deployment.

Installation Order

1. Container created with Ubuntu 22.04 template
2. Container started
3. Install script pushed to container
4. Install script executed (installs all apt packages)
5. Application software installed/downloaded
6. Services configured

APT Update

All install scripts run apt-get update before installing packages.

Non-Interactive Mode

All install scripts use export DEBIAN_FRONTEND=noninteractive to prevent interactive prompts.

Troubleshooting

Package Installation Fails

Error: E: Unable to locate package <package-name>

Solution:

# Update package lists
pct exec <vmid> -- apt-get update

# Check if package exists
pct exec <vmid> -- apt-cache search <package-name>

# Check Ubuntu version
pct exec <vmid> -- lsb_release -a

Insufficient Disk Space

Error: E: Write error - write (28: No space left on device)

Solution:

# Check disk usage
pct exec <vmid> -- df -h

# Clean apt cache
pct exec <vmid> -- apt-get clean

Network Connectivity Issues

Error: E: Failed to fetch ... Connection timed out

Solution:

# Test network connectivity
pct exec <vmid> -- ping -c 3 8.8.8.8

# Check DNS resolution
pct exec <vmid> -- nslookup archive.ubuntu.com
