keep venv & python3 -m uvicorn api:app running in the background in EC2

Question

We use venv in Ubuntu to run FastAPI as an endpoint on EC2.

Here are the steps I follow:
```
source .venv/bin/activate
python3 -m uvicorn api:app
```

The endpoint works well as long as I keep the terminal open, but when I close the terminal, I get a 502 Bad Gateway error.

What is the solution to keep python3 -m uvicorn api:app running in the background even when I'm not on the terminal?

Hi,

In linux, to run any command in background put an **&** at the end of the command and also consider using nohup.

As an example, please see below:

```
nohup python3 -m uvicorn api:app &
```

You should now be able to see the process running in the output of the below command:

```
ps -ef
```

Hope this helps!

Thanks,
Rama
