On a fresh Ubuntu 22.04 or 24.04 server, this single command installs every dependency and opens the web installer.
curl -fsSL https://mrwhatsapp.com/install.sh | bash
What it installs
- Node 20 — the runtime for both processes
- PostgreSQL 15 + pgvector — conversations and knowledge-base vectors
- Redis — job queue and hold timers
- Google Chrome — headless, drives WhatsApp Web
- PM2 — keeps both processes alive across reboots
Ubuntu 24.04 note
Chrome's audio dependency was renamed. On 24.04 the package is libasound2t64, not libasound2. The installer picks the right one for you — this only matters if you are installing by hand.
Then what
Open https://your-domain.com/install and follow the eight steps: requirements, database, host, licence, admin account, business details, finish. The installer locks itself when it is done so it cannot be run twice.
