2.1 Update System Packages

apt update && apt upgrade -y

2.2 Create a Non-Root User

usermod -aG sudo openclaw

2.3 Configure SSH Security

Edit SSH configuration:

nano /etc/ssh/sshd_config

Update these settings:

PermitRootLogin no
PasswordAuthentication no
PubkeyAuthentication yes

Copy your SSH key to the new user:

mkdir -p /home/openclaw/.ssh
cp ~/.ssh/authorized_keys /home/openclaw/.ssh/
chown -R openclaw:openclaw /home/openclaw/.ssh
chmod 700 /home/openclaw/.ssh
chmod 600 /home/openclaw/.ssh/authorized_keys

Restart SSH:

systemctl restart sshd

4.4 Build the Application

npm run build

Step 5: Configure Systemd Service

Create a systemd service for automatic startup:

RestartSec=10
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=openclaw

[Install]
WantedBy=multi-user.target

Enable and start the service:

sudo systemctl daemon-reload
sudo systemctl enable openclaw
sudo systemctl start openclaw

Check status:

sudo systemctl status openclaw

Step 6: Configure Firewall

Set up UFW firewall for your openclaw vps:

sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw allow ssh
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw enable

Step 7: Set Up Nginx Reverse Proxy

Install Nginx:

sudo apt install -y nginx

Create Nginx configuration:

sudo nano /etc/nginx/sites-available/openclaw

Add:

server {
    listen 80;
    server_name your-domain.com;

    location / {
        proxy_pass http://localhost:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        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_cache_bypass $http_upgrade;
    }
}

Enable the site:
