Hostinger VPS Setup for OpenClaw

Hostinger is a popular and cost-effective VPS provider in India. While the general Ubuntu setup guide applies to any VPS, Hostinger’s hPanel has some specific quirks you should be aware of when deploying OpenClaw.

1. Choosing the Right Plan

OpenClaw Gateway and an associated Agent process can run on a 1GB RAM machine, but 2GB is recommended for smooth PM2 daemon operation and database overhead.

• KVM 1 (1GB RAM): Sufficient for a personal bot with a single channel (e.g., Telegram).
• KVM 2 (2GB RAM): Recommended. Provides enough headroom for running multiple channels (WhatsApp + Telegram) and executing complex tools without out-of-memory (OOM) crashes.

2. OS Selection (Ubuntu 22.04 LTS)

When setting up your VPS in hPanel:

1. Go to VPS -> Manage -> OS & Panel.
2. Select Operating System.
3. Choose Ubuntu and select version 22.04 64bit.
4. Set a strong root password. You will need this for the initial SSH connection.

3. SSH Access

You can access your VPS via Hostinger’s browser terminal, but it is highly recommended to use a native terminal (like Windows Terminal, macOS Terminal, or PuTTY).

To find your IP:

1. Go to your VPS Dashboard in hPanel.
2. Look for the VPS IP block (e.g., 193.168.1.100).

Open your terminal and connect:

ssh root@193.168.1.100

(Enter the root password you created during OS selection).

Once logged in, immediately follow the Fresh Ubuntu VPS Setup guide to create a non-root user. Running OpenClaw as root is a major security risk.

4. Hostinger’s Built-in Firewall

Hostinger provides a hardware-level firewall through hPanel, which sits in front of your Ubuntu VPS.

If you enable Hostinger’s firewall, it will block all traffic by default except SSH.

1. Go to VPS -> Manage -> Security -> Firewall.
2. Click Create firewall configuration.
3. Add a rule to ALLOW SSH (Port 22).
4. Add a rule to ALLOW HTTP (Port 80) and HTTPS (Port 443) if you plan to use a reverse proxy like Caddy or Nginx for your webhooks.

5. IPv6 Considerations

Hostinger often assigns an IPv6 address alongside your IPv4 address. If your DNS is routed via Cloudflare or another proxy, ensure you are not accidentally exposing your Gateway over the IPv6 interface.

By default, the safest route is to bind OpenClaw strictly to 127.0.0.1 or a Tailscale IP (100.x.x.x), which ignores the public IPv6 assignment entirely.
