Stable Diffusion is an open-source AI-powered text-to-image generation model developed by Stability AI. It uses deep learning and latent diffusion models (LDMs) to generate high-quality images from text prompts. Unlike cloud-based solutions like DALL·E or MidJourney, Stable Diffusion runs locally on consumer hardware, making it a powerful tool for artists, developers, and AI researchers.

Step 1: Create a Server Instance on Shape.Host

Before installing Stable Diffusion, you need a server to host your environment. Here’s how to set up a server instance on Shape.Host:

Access Shape.Host: Log in to your Shape.Host account and go to the Cloud VPS section.

Start a New Instance: Click on “Create” and choose the server type that fits your project needs.

Select a Location: Pick a data center near your audience for better performance.

Choose a Plan: Select a hosting plan that matches your resource requirements and budget. Ensure the plan includes an NVIDIA GPU for Stable Diffusion.

Set the OS: Choose Ubuntu 24.04 as your operating system.

Complete the Setup: Review your settings and click “Create Instance” to launch your instance. It will be ready shortly.

In Dashboard you will find your Instance IP.

---

Step 2: Connect to Your Instance

Once your server is ready, you need to connect to it using SSH. Here’s how to do it:

• Linux/macOS: Open your terminal and use the following command:

  ssh root@your_server_ip

Replace your_server_ip with the server’s IP address.

• Windows: Use an SSH client like PuTTY. Enter your server’s IP address, specify the port (usually 22), and click “Open.” Log in with your username and password.

---

Step 3: Verify NVIDIA Drivers

Before proceeding, ensure that the NVIDIA drivers are installed and the GPU is detected. Run the following command to check:

nvidia-smi

If the GPU is detected, you will see details about the GPU, such as its model, driver version, and memory usage. If the GPU is not detected, you will need to install the NVIDIA drivers. Refer to the official NVIDIA documentation for installation instructions.

---

Step 4: Update the System

Before installing any software, it’s a good practice to update your system to ensure all packages are up to date. Run the following command:

apt update

---

Step 5: Install Required Dependencies

Install the necessary dependencies for Stable Diffusion:

sudo apt install wget git python3 python3-venv libgl1 libglib2.0-0 -y

---

Step 6: Install Python 3.10

Stable Diffusion requires Python 3.10. Add the deadsnakes PPA and install Python 3.10:

sudo add-apt-repository ppa:deadsnakes/ppa
apt update
apt install python3.10 -y
apt install python3.10-venv -y

---

Step 7: Create a Dedicated User

For security purposes, create a dedicated user to run Stable Diffusion:

adduser shape

Switch to the new user:

su - shape

---

Step 8: Set Up Stable Diffusion

Create a directory for Stable Diffusion and navigate to it:

mkdir stable
cd stable

Download the webui.sh script from the Stable Diffusion WebUI repository:

wget -q https://raw.githubusercontent.com/AUTOMATIC1111/stable-diffusion-webui/master/webui.sh

Make the script executable:

chmod +x webui.sh

---

Step 9: Create a Python Virtual Environment

Create a Python virtual environment to isolate the Stable Diffusion dependencies:

python3 -m venv venv

---

Step 10: Run the WebUI Script

Start the Stable Diffusion WebUI by running the following command:

./webui.sh --share

This script will download and install all required dependencies, including the Stable Diffusion model. Once the installation is complete, the script will provide a URL to access the Stable Diffusion WebUI.

---

Step 11: Access Stable Diffusion

After the installation finishes, you will see a URL in the terminal output. Open this URL in your web browser to access the Stable Diffusion WebUI. You can now start generating images using text prompts!
