### Ejecutar el servidor { #run-the-server }

Luego, ejecutarías el servidor pasando las configuraciones como variables de entorno, por ejemplo, podrías establecer un `ADMIN_EMAIL` y `APP_NAME` con:

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

### Запуск сервера { #run-the-server }

Далее вы можете запустить сервер, передав конфигурации через переменные окружения. Например, можно задать `ADMIN_EMAIL` и `APP_NAME` так:

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

### Den Server ausführen { #run-the-server }

Als Nächstes würden Sie den Server ausführen und die Konfigurationen als Umgebungsvariablen übergeben. Sie könnten beispielsweise `ADMIN_EMAIL` und `APP_NAME` festlegen mit:

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

### Executar o servidor { #run-the-server }

Em seguida, você executaria o servidor passando as configurações como variáveis de ambiente, por exemplo, você poderia definir `ADMIN_EMAIL` e `APP_NAME` com:

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```
