Next Steps for Deployment

Step 1: Pre-Deployment Verification

# Validate all configs
./scripts/validate-besu-config.sh

# Verify no deprecated options
./scripts/cleanup-besu-deprecated-options.sh --dry-run

# Audit configs against templates
./scripts/audit-besu-configs.sh

Expected: All validations pass ✅

Step 2: Deploy Configurations

# Dry-run first (recommended)
./scripts/deploy-besu-configs.sh --dry-run

# Deploy to all nodes (when ready)
./scripts/deploy-besu-configs.sh

Deployment Order:

  1. Validators (1000-1004) - First
  2. Sentries (1500-1503) - Second
  3. RPC Nodes (2500+) - Last

Process:

  • Backs up existing configs
  • Copies cleaned configs to nodes
  • Validates configs before deployment
  • Restarts services gracefully
  • Verifies services start successfully

Step 3: Monitor Deployment

Follow docs/04-configuration/BESU_DEPLOYMENT_MONITORING.md:

Immediate (0-1 hour):

  • ✅ Verify all services started
  • ✅ Check for configuration errors
  • ✅ Verify no restart loops
  • ✅ Check logging levels

Short-term (1-6 hours):

  • ✅ Monitor service status
  • ✅ Verify network connectivity
  • ✅ Test consensus (validators)
  • ✅ Test archive queries (sentries)

Medium-term (6-48 hours):

  • ✅ Monitor resource usage
  • ✅ Check peer connections
  • ✅ Verify sync status
  • ✅ Monitor performance

Step 4: Verify Configuration

# Verify logging levels on each node type
# Validators should show WARN logs
pct exec 1000 -- journalctl -u besu-validator.service -n 20

# Sentries should show INFO logs
pct exec 1500 -- journalctl -u besu-sentry.service -n 20

# RPC nodes should show WARN logs
pct exec 2500 -- journalctl -u besu-rpc.service -n 20

# Check for configuration errors
pct exec 1000 -- journalctl -u besu-validator.service | grep -i "error\|unknown option"

Expected: No configuration errors ✅
