# Advanced Post-installation Tasks

This page explains some advanced tasks and configuration options that can be performed after the bot installation and may be uselful in some environments.

If you do not know what things mentioned here mean, you probably do not need it.

## Configure the bot running as a systemd service

Copy the `freqtrade.service` file to your systemd user directory (usually `~/.config/systemd/user`) and update `WorkingDirectory` and `ExecStart` to match your setup.

!!! Note
    Certain systems (like Raspbian) don't load service unit files from the user directory. In this case, copy `freqtrade.service` into `/etc/systemd/user/` (requires superuser permissions).

After that you can start the daemon with:

```bash
systemctl --user start freqtrade
```

For this to be persistent (run when user is logged out) you'll need to enable `linger` for your freqtrade user.

```bash
sudo loginctl enable-linger "$USER"
```

If you run the bot as a service, you can use systemd service manager as a software watchdog monitoring freqtrade bot 
state and restarting it in the case of failures. If the `internals.sd_notify` parameter is set to true in the 
configuration or the `--sd-notify` command line option is used, the bot will send keep-alive ping messages to systemd 
using the sd_notify (systemd notifications) protocol and will also tell systemd its current state (Running or Stopped) 
when it changes. 

The `freqtrade.service.watchdog` file contains an example of the service unit configuration file which uses systemd 
as the watchdog.

!!! Note
    The sd_notify communication between the bot and the systemd service manager will not work if the bot runs in a Docker container.
