1. Configure the VM

1.1 Create the instance

On your preferred VPS provider:

• Choose Ubuntu 24.04 LTS
• Select the minimum plan (1 vCPU / 1 GB RAM)
• Set a strong root password or configure SSH key
• Note the public IP (e.g., 203.0.113.10)

1.2 Connect via SSH

ssh root@203.0.113.10

1.3 Update the system

apt update && apt upgrade -y

1.4 Install Docker

# Install dependencies
apt install -y ca-certificates curl gnupg

# Add official Docker repository
install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
chmod a+r /etc/apt/keyrings/docker.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $ (. /etc/os-release && echo "$VERSION_CODENAME") stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null
apt update
apt install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin

1.5 Install nginx

apt install -y nginx

1.6 Configure Firewall (UFW)

ufw default deny incoming
ufw default allow outgoing
ufw allow 22/tcp    # SSH
ufw allow 80/tcp    # HTTP (redirect)
ufw allow 443/tcp   # HTTPS
ufw enable

Tip: For maximum security, restrict ports 80 and 443 to Cloudflare IPs only. See the Advanced Security section.

2. Install OmniRoute

2.1 Create configuration directory

mkdir -p /opt/omniroute

2.2 Create environment variables file

cat > /opt/omniroute/.env << 'EOF'
# === Security ===
JWT_SECRET=CHANGE-TO-A-UNIQUE-64-CHAR-SECRET-KEY
INITIAL_PASSWORD=YourSecurePassword123!
API_KEY_SECRET=REPLACE-WITH-ANOTHER-SECRET-KEY
STORAGE_ENCRYPTION_KEY=REPLACE-WITH-THIRD-SECRET-KEY
STORAGE_ENCRYPTION_KEY_VERSION=v1
MACHINE_ID_SALT=CHANGE-TO-A-UNIQUE-SALT
OMNIROUTE_WS_BRIDGE_SECRET=REPLACE-WITH-WS-BRIDGE-SECRET  # REQUIRED em produção: usado pelo Codex Responses WS bridge

# === App ===
PORT=20128
NODE_ENV=production
HOSTNAME=0.0.0.0
DATA_DIR=/app/data
APP_LOG_TO_FILE=true
AUTH_COOKIE_SECURE=true
REQUIRE_API_KEY=false

# === URLs (change to your domain) ===
# Internal server-to-server base URL for scheduled jobs / self-fetches.
BASE_URL=http://127.0.0.1:20128
# Browser-facing URL used for OAuth callbacks, dashboard links, and generated public URLs.
NEXT_PUBLIC_BASE_URL=https://llms.seudominio.com
# Optional explicit public origin override for generated public asset URLs.
# OMNIROUTE_PUBLIC_BASE_URL=https://llms.seudominio.com

# === Cloud Sync (optional) ===
# CLOUD_URL=https://cloud.omniroute.online
# NEXT_PUBLIC_CLOUD_URL=https://cloud.omniroute.online
EOF

⚠️ IMPORTANT: Generate unique secret keys! Use openssl rand -hex 32 for each key.

2.3 Start the container

docker pull diegosouzapw/omniroute:latest

docker run -d \
  --name omniroute \
  --restart unless-stopped \
  --env-file /opt/omniroute/.env \
  -p 20128:20128 \
  -v omniroute-data:/app/data \
  diegosouzapw/omniroute:latest

2.4 Verify that it is running

docker ps | grep omniroute
docker logs omniroute --tail 20

It should display: [DB] SQLite database ready and listening on port 20128.

3. Configure nginx (Reverse Proxy)

3.1 Generate SSL certificate (Cloudflare Origin)

In the Cloudflare dashboard:

1. Go to SSL/TLS → Origin Server
2. Click Create Certificate
3. Keep the defaults (15 years, *.yourdomain.com)
4. Copy the Origin Certificate and the Private Key

mkdir -p /etc/nginx/ssl

# Paste the certificate
nano /etc/nginx/ssl/origin.crt

# Paste the private key
nano /etc/nginx/ssl/origin.key

chmod 600 /etc/nginx/ssl/origin.key

3.2 Nginx Configuration

cat > /etc/nginx/sites-available/omniroute << 'NGINX'
# Default server — blocks direct access via IP
server {
    listen 80 default_server;
    listen [::]:80 default_server;
    listen 443 ssl default_server;
    listen [::]:443 ssl default_server;
    ssl_certificate     /etc/nginx/ssl/origin.crt;
    ssl_certificate_key /etc/nginx/ssl/origin.key;
    server_name _;
    return 444;
}

# OmniRoute — HTTPS
server {
    listen 443 ssl;
    listen [::]:443 ssl;
    server_name llms.yourdomain.com;  # Change to your domain

    ssl_certificate     /etc/nginx/ssl/origin.crt;
    ssl_certificate_key /etc/nginx/ssl/origin.key;
    ssl_protocols TLSv1.2 TLSv1.3;

    client_max_body_size 100M;

    location / {
        proxy_pass http://127.0.0.1:20128;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-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;

        # WebSocket support
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        # SSE (Server-Sent Events) — streaming AI responses
        proxy_buffering off;
        proxy_cache off;
        proxy_read_timeout 600s;
        proxy_send_timeout 600s;
    }
}

# HTTP → HTTPS redirect
server {
    listen 80;
    listen [::]:80;
    server_name llms.yourdomain.com;
    return 301 https://$server_name$request_uri;
}
NGINX

Keep reverse-proxy stream timeouts aligned with your OmniRoute timeout env vars. If you raise FETCH_TIMEOUT_MS / STREAM_IDLE_TIMEOUT_MS, raise proxy_read_timeout / proxy_send_timeout above the same threshold.

OmniRoute uses NEXT_PUBLIC_BASE_URL as the canonical browser-facing origin for OAuth callbacks and generated public links. Authenticated dashboard writes use same-origin requests plus session-bound CSRF protection, so they do not require a static public base URL. The X-Forwarded-* headers above are still useful routing metadata, but they are not a replacement for setting the explicit public URL when OAuth or generated browser links need one. Only enable OMNIROUTE_TRUST_PROXY if OmniRoute is not directly reachable by clients and your proxy strips/rebuilds incoming forwarded headers.

3.3 Enable and Test

# Remove default configuration
rm -f /etc/nginx/sites-enabled/default

# Enable OmniRoute
ln -sf /etc/nginx/sites-available/omniroute /etc/nginx/sites-enabled/omniroute

# Test and reload
nginx -t && systemctl reload nginx

4. Configure Cloudflare DNS

4.1 Add DNS record

In the Cloudflare dashboard → DNS:

Type	Name	Content	Proxy
A	llms	203.0.113.10 (VM IP)	✅ Proxied

4.2 Configure SSL

Under SSL/TLS → Overview:

• Mode: Full (Strict)

Under SSL/TLS → Edge Certificates:

• Always Use HTTPS: ✅ On
• Minimum TLS Version: TLS 1.2
• Automatic HTTPS Rewrites: ✅ On

4.3 Testing

curl -sI https://llms.seudominio.com/health
# Should return HTTP/2 200

---

5. Operations and Maintenance

Upgrade to a new version

docker pull diegosouzapw/omniroute:latest
docker stop omniroute && docker rm omniroute
docker run -d --name omniroute --restart unless-stopped \
  --env-file /opt/omniroute/.env \
  -p 20128:20128 \
  -v omniroute-data:/app/data \
  diegosouzapw/omniroute:latest

View logs

docker logs -f omniroute          # Real-time stream
docker logs omniroute --tail 50   # Last 50 lines

Manual database backup

# Copy data from the volume to the host
docker cp omniroute:/app/data ./backup-$(date +%F)

# Or compress the entire volume
docker run --rm -v omniroute-data:/data -v $(pwd):/backup \
  alpine tar czf /backup/omniroute-data-$(date +%F).tar.gz /data

Restore from backup

docker stop omniroute
docker run --rm -v omniroute-data:/data -v $(pwd):/backup \
  alpine sh -c "rm -rf /data/* && tar xzf /backup/omniroute-data-YYYY-MM-DD.tar.gz -C /"
docker start omniroute

6. Advanced Security

Restrict nginx to Cloudflare IPs

cat > /etc/nginx/cloudflare-ips.conf << 'CF'
# Cloudflare IPv4 ranges — update periodically
# https://www.cloudflare.com/ips-v4/
set_real_ip_from 173.245.48.0/20;
set_real_ip_from 103.21.244.0/22;
set_real_ip_from 103.22.200.0/22;
set_real_ip_from 103.31.4.0/22;
set_real_ip_from 141.101.64.0/18;
set_real_ip_from 108.162.192.0/18;
set_real_ip_from 190.93.240.0/20;
set_real_ip_from 188.114.96.0/20;
set_real_ip_from 197.234.240.0/22;
set_real_ip_from 198.41.128.0/17;
set_real_ip_from 162.158.0.0/15;
set_real_ip_from 104.16.0.0/13;
set_real_ip_from 104.24.0.0/14;
set_real_ip_from 172.64.0.0/13;
set_real_ip_from 131.0.72.0/22;
real_ip_header CF-Connecting-IP;
CF

Add the following to nginx.conf inside the http {} block:

include /etc/nginx/cloudflare-ips.conf;

Install fail2ban

apt install -y fail2ban
systemctl enable fail2ban
systemctl start fail2ban

# Check status
fail2ban-client status sshd

Block direct access to the Docker port

# Prevent direct external access to port 20128
iptables -I DOCKER-USER -p tcp --dport 20128 -j DROP
iptables -I DOCKER-USER -i lo -p tcp --dport 20128 -j ACCEPT

# Persist the rules
apt install -y iptables-persistent
netfilter-persistent save

---

7. Deploy to Cloudflare Workers (Optional)

For remote access via Cloudflare Workers (without exposing the VM directly):

# In the local repository
cd omnirouteCloud
npm install
npx wrangler login
npx wrangler deploy

See also TUNNELS_GUIDE.md for the in-repo Cloudflare Tunnel walkthrough. The standalone omnirouteCloud/ worker lives in a separate companion repo.

---

Port Summary

Port	Service	Access
22	SSH	Public (with fail2ban)
80	nginx HTTP	Redirect → HTTPS
443	nginx HTTPS	Via Cloudflare Proxy
20128	OmniRoute	Localhost only (via nginx)

Low-Memory / Small VPS Optimization

For deployments on small VPS instances (1 GB RAM or less):

• Disable background services — set OMNIROUTE_DISABLE_BACKGROUND_SERVICES=1 to skip scheduler, MCP server, and periodic maintenance tasks. See docs/reference/ENVIRONMENT.md.
• Use SQLite WAL mode — enabled by default, reduces peak memory during concurrent reads.
• Cap the V8 heap — set OMNIROUTE_MEMORY_MB (e.g. 512) so the runtime does not calibrate a ceiling larger than the VM. See docs/reference/ENVIRONMENT.md.
• Heavyweight admission auto-scales with the heap cap – once OMNIROUTE_MEMORY_MB is set above, the ingest byte budget (OMNIROUTE_CHAT_MAX_INFLIGHT_BYTES) derives itself from that same ceiling, so a memory-constrained VM already gets a smaller concurrent-request budget with no extra tuning; excess requests get a retryable 503 with Retry-After instead of competing for memory. Set the legacy OMNIROUTE_CHAT_MAX_HEAVY_IN_FLIGHT request-count cap only if you need a hard ceiling on top of that.
• Avoid next build on the VPS — build locally and deploy the standalone output (.next/standalone/).
• Monitor with top / free -m — OmniRoute typically uses 200-400 MB RSS at idle on a 1 GB VM.
