# Running a Gradio App on your Web Server with Nginx

Tags: DEPLOYMENT, WEB SERVER, NGINX

## Introduction

Gradio is a Python library that allows you to quickly create customizable web apps for your machine learning models and data processing pipelines. Gradio apps can be deployed on [Hugging Face Spaces](https://hf.space) for free. 

In some cases though, you might want to deploy a Gradio app on your own web server. You might already be using [Nginx](https://www.nginx.com/), a highly performant web server, to serve your website (say `https://www.example.com`), and you want to attach Gradio to a specific subpath on your website (e.g. `https://www.example.com/gradio-demo`). 

In this Guide, we will guide you through the process of running a Gradio app behind Nginx on your own web server to achieve this.

**Prerequisites**

1. A Linux web server with [Nginx installed](https://www.nginx.com/blog/setting-up-nginx/) and [Gradio installed](/quickstart)  
    
2. A working Gradio app saved as a python file on your web server

## Editing your Nginx configuration file

1. Start by editing the Nginx configuration file on your web server. By default, this is located at: `/etc/nginx/nginx.conf`

In the `http` block, add the following line to include server block configurations from a separate file:

```bash
include /etc/nginx/sites-enabled/*;
```

2. Create a new file in the `/etc/nginx/sites-available` directory (create the directory if it does not already exist), using a filename that represents your app, for example: `sudo nano /etc/nginx/sites-available/my_gradio_app`

3. Paste the following into your file editor:

```bash
server {
    listen 80;
    server_name example.com www.example.com;  # Change this to your domain name 

    location /gradio-demo/ {  # Change this if you'd like to server your Gradio app on a different path
        proxy_pass http://127.0.0.1:7860/; # Change this if your Gradio app will be running on a different port
        proxy_redirect off;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
    }
}
```

## Run your Gradio app on your web server

1. Before you launch your Gradio app, you'll need to set the `root_path` to be the same as the subpath that you specified in your nginx configuration. This is necessary for Gradio to run on any subpath besides the root of the domain.

Here's a simple example of a Gradio app with a custom `root_path`:

```python
import gradio as gr
import time

def test(x):
time.sleep(4)
return x

gr.Interface(test, "textbox", "textbox").queue().launch(root_path="/gradio-demo")
```

2. Start a `tmux` session by typing `tmux` and pressing enter (optional) 

It's recommended that you run your Gradio app in a `tmux` session so that you can keep it running in the background easily

3. Then, start your Gradio app. Simply type in `python` followed by the name of your Gradio python file. By default, your app will run on `localhost:7860`, but if it starts on a different port, you will need to update the nginx configuration file above.

## Restart Nginx

1. If you are in a tmux session, exit by typing CTRL+B (or CMD+B), followed by the "D" key.

2. Finally, restart nginx by running `sudo systemctl restart nginx`. 

And that's it! If you visit `https://example.com/gradio-demo` on your browser, you should see your Gradio app running there
