Home Assistant can run as a daemon within init.d with the script below.
### {% linkable_title 1. Copy script %}
Copy the script at the end of this page to `/etc/init.d/hass-daemon`.
After that, set the script to be executable:
```bash
$ sudo chmod +x /etc/init.d/hass-daemon
```
### {% linkable_title 2. Select a user. %}
Create or pick a user that the Home Assistant daemon will run under. Update script to set `RUN_AS` to the username that should be used to execute hass.
### {% linkable_title 3. Register the daemon with Linux %}
```bash
$ sudo update-rc.d hass-daemon defaults
```
### {% linkable_title 4. Install this service %}
```bash
$ sudo service hass-daemon install
```
### {% linkable_title 5. Restart Machine %}
That's it. Restart your machine and Home Assistant should start automatically.
If HA does not start, check the log file output for errors at `/var/opt/homeassistant/home-assistant.log`
### {% linkable_title Extra: Running commands before hass executes %}
If any commands need to run before executing hass (like loading a virutal environment), put them in PRE_EXEC. This command must end with a semicolon.
### {% linkable_title Daemon script %}
```bash
#!/bin/sh
### BEGIN INIT INFO
