Installation

Prerequisites#

• Linux server (Ubuntu 24.04+/Debian 12+/Alpine 3.20+)
• Root or sudo access
• Ports 80 and 443 open
• A domain with DNS A record pointing to your server's IP

Step 1 — Install Docker#

curl -fsSL https://get.docker.com | sh

Add your user to the docker group (optional, avoids using sudo):

usermod -aG docker $USER

Step 2 — Install Demyx#

Run the one-liner installer:

bash -c "$(curl -fsSL https://demyx.sh/install)"

The installer pulls release-pinned Demyx 1.11.0 images, creates the host compose files, and installs the demyx helper script:

After installation, the demyx helper script is placed at /usr/local/bin/demyx.

By default, the installer sends a one-time active install ping. To install without that ping and start with telemetry disabled:

wget https://demyx.sh/install
bash install --no-ping

Step 3 — Configure Your Environment#

Open the Demyx host environment file:

demyx host edit

Set at minimum:

DEMYX_DOMAIN=yourdomain.com
DEMYX_EMAIL=you@yourdomain.com

These values are required for Traefik to obtain Let's Encrypt SSL certificates.

Step 4 — Restart the Stack#

demyx host restart

Step 5 — Create Your First WordPress Site#

demyx run domain.tld --ssl

Demyx will output WordPress credentials once the site is ready. Visit https://domain.tld — it's live.

What Happens on First Login#

After installation, running demyx shows the Message of the Day (MOTD) with system information:
