# Verify
echo $ATLAS-GATE_BOOTSTRAP_SECRET
```
### Step 5: Create Systemd Service
```bash
# Create service file
sudo tee /etc/systemd/system/atlas-gate.service > /dev/null << 'EOF'
[Unit]
Description=ATLAS-GATE MCP Server
After=network-online.target
Wants=network-online.target
[Service]
Type=simple
User=pi
WorkingDirectory=/home/pi/ATLAS-GATE-MCP
EnvironmentFile=/home/pi/ATLAS-GATE-MCP/.env.production
ExecStart=/usr/bin/node bin/ATLAS-GATE-HTTP.js

sudo systemctl enable atlas-gate
sudo systemctl start atlas-gate
# Check status
sudo systemctl status atlas-gate
# View logs
sudo journalctl -u atlas-gate -f
```
### Step 6: Configure Nginx Reverse Proxy
```bash
# Install nginx
sudo apt install -y nginx
# Create configuration
sudo tee /etc/nginx/sites-available/atlas-gate > /dev/null << 'EOF'
upstream atlas_gate {
server 127.0.0.1:3000;
}
server {
listen 80;
server_name _;
# HTTP to HTTPS redirect (optional)
# return 301 https://$host$request_uri;
client_max_body_size 10M;
location / {
proxy_pass http://atlas_gate;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_read_timeout 30s;
proxy_connect_timeout 10s;
}
location /health {
proxy_pass http://atlas_gate;
access_log off;
}
}
EOF
# Enable site
sudo ln -sf /etc/nginx/sites-available/atlas-gate /etc/nginx/sites-enabled/
sudo rm -f /etc/nginx/sites-enabled/default
# Test configuration
sudo nginx -t
# Start nginx
sudo systemctl restart nginx
sudo systemctl enable nginx
```
### Step 7: (Optional) Configure SSL/TLS
```bash
# Install certbot
sudo apt install -y certbot python3-certbot-nginx
# Get certificate (requires public domain)
sudo certbot certonly --nginx -d your-domain.com
# Update nginx config to use HTTPS
sudo certbot renew --nginx
# Check renewal
sudo certbot renew --dry-run
```
### Step 8: Configure Remote Access
#### Option A: SSH Tunnel (Simplest)
```bash
# On your local machine
ssh -L 3000:localhost:3000 pi@raspberrypi.local
# Then access locally:
curl http://localhost:3000/health
```
#### Option B: ngrok (Fast, No Setup)
```bash
# On RPi
curl https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-arm.zip -o ngrok.zip
unzip ngrok.zip
sudo mv ngrok /usr/local/bin/
# Create ngrok config
cat > ~/.ngrok2/ngrok.yml << 'EOF'
authtoken: YOUR_TOKEN_HERE
tunnels:
atlas-gate:
proto: http
addr: localhost:3000
EOF
# Start tunnel
ngrok start atlas-gate
# ngrok will provide a public URL: https://xxxx-xxx-xxx-xx.ngrok.io
```
#### Option C: Cloudflare Tunnel (Enterprise)
```bash
# Install cloudflared
curl -L https://pkg.cloudflare.com/cloudflare-release.key | sudo gpg --yes --dearmor --output /usr/share/keyrings/cloudflare-archive-keyring.gpg
echo 'deb [signed-by=/usr/share/keyrings/cloudflare-archive-keyring.gpg] https://pkg.cloudflare.com/linux any main' | sudo tee /etc/apt/sources.list.d/cloudflare-main.list
sudo apt update
sudo apt install -y cloudflared
# Authenticate
cloudflared tunnel login
# Create tunnel
cloudflared tunnel create atlas-gate
# Configure tunnel
cat > ~/.cloudflared/config.yml << 'EOF'
tunnel: atlas-gate
credentials-file: ~/.cloudflared/<UUID>.json
ingress:
- hostname: atlas-gate.your-domain.com
service: http://localhost:3000
- service: http_status:404
EOF
# Run tunnel
cloudflared tunnel run atlas-gate
# Route to tunnel
cloudflared tunnel route dns atlas-gate atlas-gate.your-domain.com
```
#### Option D: Public IP + Firewall
```bash
# If RPi has public IP, expose via firewall
# ⚠️ Only if behind proper network security
# Router: Forward port 80/443 to RPi:3000
# Firewall: Allow port 80/443 inbound
# Then access:
curl http://your-public-ip:80/health
```

## Remote Operations
### Access from Laptop
```bash
# Via SSH tunnel
ssh -L 3000:localhost:3000 pi@raspberrypi.local
# In another terminal:
curl http://localhost:3000/health
# Create a workspace
curl -X POST http://localhost:3000/sessions/create \
-H "Content-Type: application/json" \
-d '{
"role": "WINDSURF",
"workspaceRoot": "/home/pi/ATLAS-GATE-MCP"
}'
```
### Monitor Logs Remotely
```bash
# SSH into RPi
ssh pi@raspberrypi.local
# View logs in real-time
sudo journalctl -u atlas-gate -f
# View last 100 lines
sudo journalctl -u atlas-gate -n 100
# View specific time range
sudo journalctl -u atlas-gate --since "1 hour ago"
# Search for errors
sudo journalctl -u atlas-gate | grep ERROR
```
### Check System Health
```bash
# SSH into RPi
ssh pi@raspberrypi.local
# Check memory usage
free -h
# Check disk usage
df -h
# Check CPU temp
vcgencmd measure_temp
# Check service status
sudo systemctl status atlas-gate
# Test health endpoint
curl http://localhost:3000/health | jq .
```
### Restart Service
```bash
# SSH into RPi
ssh pi@raspberrypi.local
# Restart
sudo systemctl restart atlas-gate
# Stop
sudo systemctl stop atlas-gate
# Start
sudo systemctl start atlas-gate
```
---
## Performance Tuning for RPi
### Memory Management
```bash
# Monitor memory usage
watch -n 1 'free -h && echo "---" && top -bn1 | head -15'
# If out of memory, enable swap
sudo fallocate -l 1G /var/swapfile
sudo chmod 600 /var/swapfile
sudo mkswap /var/swapfile
sudo swapon /var/swapfile
# Make permanent
echo '/var/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
```
### CPU Optimization
```bash
# Check CPU frequency
watch -n 1 'cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq'
# If throttling occurs, check temperature
vcgencmd measure_temp
# Improve cooling: add heatsinks or fan
# Passive: 3x3cm aluminum heatsinks on SoC and RAM
# Active: 5V PWM fan (controlled by GPIO)
```
### Disk I/O
```bash
# Use SSD for faster I/O
# RPi 5: USB 3.0 can boot from SSD
# RPi 4: USB 3.0 SSD faster than microSD
# Check I/O performance
sudo iotop -o
# Disable unnecessary services to free I/O
sudo systemctl disable cups
sudo systemctl disable bluetooth
```
### Network Optimization
```bash
# Test network speed
iperf3 -c your-pc-ip # Requires iperf3 server on PC
# Enable hardware checksumming
ethtool -K eth0 tx on rx on
# Adjust socket buffer sizes
echo "net.core.rmem_max=134217728" | sudo tee -a /etc/sysctl.conf
echo "net.core.wmem_max=134217728" | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
```

## Backup Strategy for RPi
### Automated Daily Backup
```bash
# Create backup script
cat > ~/backup-atlas-gate.sh << 'EOF'
#!/bin/bash
BACKUP_DIR=/mnt/backup/atlas-gate
DATE=$(date +%Y%m%d)
mkdir -p $BACKUP_DIR
# Backup workspace
tar czf $BACKUP_DIR/workspace-$DATE.tar.gz ~/ATLAS-GATE-MCP/.atlas-gate/
# Backup audit log
cp ~/ATLAS-GATE-MCP/.atlas-gate/audit.log $BACKUP_DIR/audit-$DATE.log
# Backup cosign keys (encrypted)
tar czf - ~/ATLAS-GATE-MCP/.atlas-gate/.cosign-keys | \
openssl enc -aes-256-cbc -pass file:~/.backup-password \
> $BACKUP_DIR/keys-$DATE.tar.gz.enc
# Keep last 7 days
find $BACKUP_DIR -mtime +7 -delete
echo "Backup complete: $BACKUP_DIR"
EOF
chmod +x ~/backup-atlas-gate.sh
# Schedule via cron
crontab -e
# Add: 0 2 * * * ~/backup-atlas-gate.sh
```
### Remote Backup
```bash
# Sync to external server via rsync
rsync -avz --delete \
/home/pi/ATLAS-GATE-MCP/.atlas-gate/ \
backup-server:/backups/atlas-gate/
# Or via cloud storage
rclone sync /home/pi/ATLAS-GATE-MCP/.atlas-gate/ \
b2:my-bucket/atlas-gate/
```
---
## Troubleshooting
### Service Won't Start
```bash
# Check logs
sudo journalctl -u atlas-gate -n 50
# Check if port 3000 is in use
sudo lsof -i :3000
# Manually test
cd ~/ATLAS-GATE-MCP
node bin/ATLAS-GATE-HTTP.js
# Check Node version
node --version # Must be 18+
```
### Out of Memory
```bash
# Check current usage
free -h
# Kill largest process
ps aux --sort=-%mem | head -5
# sudo kill -9 <PID>
# Reduce Node.js heap
export NODE_OPTIONS="--max-old-space-size=256"
# Restart service
sudo systemctl restart atlas-gate
```
### Network Connectivity Issues
```bash
# Check connection
ping 8.8.8.8
# Check DNS
nslookup google.com
# Check if port is open
sudo ss -tlnp | grep 3000
# Test from external machine
curl -v http://your-rpi-ip:80/health
```
### Audit Log Corruption
```bash
# Verify integrity
node -e "
import { verifyAuditLogIntegrity } from './core/audit-system.js';
const result = await verifyAuditLogIntegrity(process.cwd());
console.log(JSON.stringify(result, null, 2));
"
# If corrupted, restore from backup
cp /mnt/backup/atlas-gate/audit-*.log .atlas-gate/audit.log
```
---
## Remote Development Workflow
### SSH Development Setup
```bash
# On your local machine, edit via SSH
code --remote ssh-remote+pi@raspberrypi.local ~/ATLAS-GATE-MCP
# Or use vim
ssh pi@raspberrypi.local
vim ~/ATLAS-GATE-MCP/core/my-file.js
```
### Syncing Code
```bash
# Watch local files and sync to RPi
fswatch -o ~/ATLAS-GATE-MCP | xargs -I {} rsync -avz \
~/ATLAS-GATE-MCP/ \
pi@raspberrypi.local:~/ATLAS-GATE-MCP/
# Or one-time sync
rsync -avz --exclude=node_modules --exclude=.git \
~/ATLAS-GATE-MCP/ \
pi@raspberrypi.local:~/ATLAS-GATE-MCP/
# Test changes
ssh pi@raspberrypi.local 'cd ~/ATLAS-GATE-MCP && npm run verify'
```
