Linux AI Server — Headless AI Inference Cluster

Turn your Linux servers into a distributed AI inference cluster. No GUI, no Docker, no Kubernetes — just Linux + pip install. Your rack-mounted servers, cloud VMs, and spare Linux boxes all serve AI through one endpoint.

Why Linux AI server

  • Zero GUI overhead — headless Linux AI uses all resources for inference, not desktops
  • systemd native — Linux AI server starts on boot, restarts on failure, logs to journald
  • SSH management — manage your Linux AI server cluster entirely over SSH
  • Any Linux distro — Ubuntu, Debian, RHEL, Fedora, Arch, Alpine — if it runs Ollama, it joins the fleet
  • NVIDIA CUDA — Linux AI server uses NVIDIA GPUs natively. No compatibility issues.
  • Fleet routing — multiple Linux AI servers share the load. 7-signal scoring picks the best one.

Linux AI server setup

Quick install on each Linux server

# Install Ollama on Linux
curl -fsSL https://ollama.ai/install.sh | sh

# Install the Linux AI router
pip install ollama-herd

Linux AI server router (pick one server)

herd          # start Linux AI server router on port 11435
herd-node     # register this Linux AI server

Linux AI server nodes (all other servers)

herd-node     # auto-discovers the Linux AI server router
# Or explicit: herd-node --router-url http://router-ip:11435

Use your Linux AI server

OpenAI SDK

from openai import OpenAI

# Your Linux AI server endpoint
client = OpenAI(base_url="http://linux-ai-server:11435/v1", api_key="not-needed")

response = client.chat.completions.create(
    model="llama3.3:70b",
    messages=[{"role": "user", "content": "Write a Terraform module for AWS ECS"}],
    stream=True,
)
for chunk in response:
    print(chunk.choices[0].delta.content or "", end="")

curl from any machine

# Hit your Linux AI server from anywhere on the network
curl http://linux-ai-server:11435/api/chat -d '{
  "model": "codestral",
  "messages": [{"role": "user", "content": "Write a Dockerfile for a FastAPI app"}],
  "stream": false
}'

Linux AI server environment

# Optimize Linux AI server Ollama
sudo systemctl edit ollama
# Add under [Service]:
#   Environment="OLLAMA_KEEP_ALIVE=-1"
#   Environment="OLLAMA_MAX_LOADED_MODELS=-1"
#   Environment="OLLAMA_NUM_PARALLEL=2"
sudo systemctl restart ollama

Linux AI server firewall

Guardrails

  • Linux AI server model downloads require explicit user confirmation.
  • Linux AI server model deletion requires explicit user confirmation.
  • Never delete or modify files in ~/.fleet-manager/.
  • No models are downloaded automatically — all pulls are user-initiated or require opt-in.
