Linux Ollama — Fleet Routing for Ollama on Linux

Run Ollama on Linux with multi-machine load balancing. Linux Ollama Herd turns multiple Linux machines into one smart Ollama endpoint. Your server rack, your desktop, your edge device — all serving AI through one Linux Ollama URL.

Linux Ollama setup

Step 1: Install Ollama on Linux

curl -fsSL https://ollama.ai/install.sh | sh

Step 2: Install Linux Ollama Herd

pip install ollama-herd

Step 3: Start the Linux Ollama router

On one Linux machine (your router):

herd          # starts Linux Ollama router on port 11435
herd-node     # registers this Linux machine

On every other Linux machine:

herd-node     # auto-discovers the Linux Ollama router via mDNS

> No mDNS? Connect Linux nodes directly: herd-node --router-url http://router-ip:11435

Linux Ollama systemd integration

Run Linux Ollama Herd as a systemd service for automatic startup:

# /etc/systemd/system/ollama-herd.service
[Unit]
Description=Linux Ollama Herd Router
After=network.target ollama.service

[Service]
Type=simple
ExecStart=/usr/local/bin/herd
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target

sudo systemctl enable ollama-herd
sudo systemctl start ollama-herd

Node agent as a Linux systemd service:

# /etc/systemd/system/ollama-herd-node.service
[Unit]
Description=Linux Ollama Herd Node Agent
After=network.target ollama.service

[Service]
Type=simple
ExecStart=/usr/local/bin/herd-node
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target

Use Linux Ollama

OpenAI SDK

from openai import OpenAI

# Your Linux Ollama fleet
client = OpenAI(base_url="http://localhost:11435/v1", api_key="not-needed")

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

curl (Ollama format)

# Linux Ollama inference
curl http://localhost:11435/api/chat -d '{
  "model": "qwen3.5:32b",
  "messages": [{"role": "user", "content": "Explain Linux process scheduling"}],
  "stream": false
}'

Linux Ollama environment setup

# Optimize Linux Ollama performance via systemd
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

Or via shell profile:

echo 'export OLLAMA_KEEP_ALIVE=-1' >> ~/.bashrc
echo 'export OLLAMA_MAX_LOADED_MODELS=-1' >> ~/.bashrc
source ~/.bashrc

Linux Ollama GPU support

> Linux Ollama supports NVIDIA CUDA, experimental AMD ROCm, and CPU-only inference.

Linux Ollama firewall

# UFW (Ubuntu/Debian)
sudo ufw allow 11435/tcp

# firewalld (RHEL/Fedora)
sudo firewall-cmd --add-port=11435/tcp --permanent
sudo firewall-cmd --reload

# iptables
sudo iptables -A INPUT -p tcp --dport 11435 -j ACCEPT
