Prefect Community

<@ULVA73B9P> Does prefect server generate a file with its PID? If so, what is its location?

:white_check_mark: thought for 62.1 seconds

Yes — *if you start it in background mode*.

*Prefect 3.x* writes the server PID to:

```text
~/.prefect/server.pid
```

More precisely, it uses:

```text
$PREFECT_HOME/server.pid
```

and `PREFECT_HOME` defaults to `~/.prefect`.

A few important details:

- `prefect server start --background` → creates the PID file
- `prefect server start` in foreground mode → does *not* create the PID file
- The PID filename is `server.pid`
- There is also a separate `services.pid` for background server services

So if you’re looking for it, check:

```text
~/.prefect/server.pid
```

Relevant source-verified behavior:
- background startup creates the file and writes the PID
- `prefect server stop` reads that file to terminate the process

If you want, I can also show you the exact CLI behavior for `prefect server start/stop` and how this changes if `PREFECT_HOME` is customized.
