Installation Guide | Delyan Documentation

What ships

One .deb for Debian / Ubuntu, one .rpm for RHEL / AlmaLinux / Rocky / Oracle Linux (x86_64). Single bundle, single process, single open port.
Dely AI Advisor ships inside the bundle. Air-gap-friendly — no internet at runtime.

Step 1 — Download the installer

A signed delyan_<version>_amd64.deb for Debian / Ubuntu hosts, or
A signed delyan-<version>.x86_64.rpm for RHEL / AlmaLinux / Rocky / Oracle Linux hosts.

Both ship with the Dely AI advisor inside the bundle, so the target server never needs internet access at install time or at runtime.

Step 2a — Install on Debian / Ubuntu

Copy the .deb onto the target server (USB stick or scp into the management bastion).
Install with apt:
sudo apt install ./delyan_<version>_amd64.deb
Start the Delyan service:
sudo systemctl enable --now delyan

Step 2b — Install on RHEL / AlmaLinux / Rocky / Oracle Linux

Copy the .rpm onto the target server.
Install with dnf (or yum on older systems):
sudo dnf install ./delyan-<version>.x86_64.rpm
Start the Delyan service:
sudo systemctl enable --now delyan

Step 3 — Verify and access

Confirm the service is running:

sudo systemctl status delyan

Open the Delyan web UI in a browser on the same network as the server:

http://<server-ip>

Default ports: 80 (HTTP) and 443 (HTTPS, once you've provisioned a certificate). The web UI runs locally on the server — no internet access is required.
