Turn Your Old PC Into a Local AI Server (Ollama Ubuntu Setup)

Blog Link : https://selftuts.in/run-ai-models-locally-and-access-on-other-device/ In this video, we will learn how to turn an old Ubuntu machine into a Local AI Server using Ollama. Instead of running heavy AI models on your daily laptop, you can run them on an older machine and access them from any device on your local Wi-Fi network. This setup allows you to run local LLM models like Llama, Qwen and others without paying for expensive cloud APIs. In this tutorial we will cover: • Running Ollama on an Ubuntu machine • Exposing the Ollama server to the local network • Accessing the AI server from another device • Using the Ollama API from your laptop This is a powerful setup for developers who want to build AI tools, AI agents, or local LLM applications. Perfect for: • Developers building AI apps • Running AI locally • Using old hardware for AI • Learning local LLM infrastructure 00:00 Introduction 00:09 Architecture Overview 00:23 Local AI Server Setup 00:56 Why Running AI on Laptop is Problem 01:24 Best Architecture for Local AI 01:41 Prerequisites (Ubuntu + Ollama) 02:02 Why Local AI is Important in 2026 03:10 SSH into Ubuntu Machine 03:54 Check Ollama Version 04:06 Enable Network Access 04:40 Configure Ollama Host 05:25 Save Configuration File 06:03 Reload Systemd 06:50 Restart Ollama Server 07:13 Check Server Status 07:40 Find Ubuntu IP Address 08:03 Access Ollama from Mac 08:36 Test Server Connection 09:18 Using Ollama API 09:33 Final Thoughts If you enjoy AI tutorials, coding videos and practical development guides, make sure to subscribe to the channel. #ollama #localAI #AIserver #localllm #AIdevelopment
