Autostart Using Systemd

<p>Newer linux distributions are trending towards using <code class="highlighter-rouge">systemd</code> for managing daemons. Typically, systems based on Fedora, ArchLinux, or Debian (8 or later) use <code class="highlighter-rouge">systemd</code>. This includes Ubuntu releases including and after 15.04, CentOS, and Red Hat. If you are unsure if your system is using <code class="highlighter-rouge">systemd</code>, you may check with the following command:</p>
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="gp">$ </span>ps -p 1 -o <span class="nv">comm</span><span class="o">=</span>
</code></pre>
</div>
<p>If the preceding command returns the string <code class="highlighter-rouge">systemd</code>, you are likely using <code class="highlighter-rouge">systemd</code>.</p>
<p>If you want Home Assistant to be launched automatically, an extra step is needed to setup <code class="highlighter-rouge">systemd</code>. A service file is needed to control Home Assistant with <code class="highlighter-rouge">systemd</code>. The template below should be created using a text editor. Note, root permissions via ‘sudo’ will likely be needed. The following should be noted to modify the template:</p>
<ul>
<li><code class="highlighter-rouge">ExecStart</code> contains the path to <code class="highlighter-rouge">hass</code> and this may vary. Check with <code class="highlighter-rouge">whereis hass</code> for the location.</li>
<li>If running Home Assistant in a python virtual environment or a docker, please skip to section below.</li>
<li>For most systems, the file is <code class="highlighter-rouge">/etc/systemd/system/home-assistant@[your user].service</code> with [your user] replaced by the user account that Home Assistant will run as - normally <code class="highlighter-rouge">homeassistant</code>. For Ubuntu 16.04, the file is <code class="highlighter-rouge">/lib/systemd/system/home-assistant.service</code> and requires running this command <code class="highlighter-rouge">sudo ln -s /lib/systemd/system/home-assistant.service /etc/systemd/system/home-assistant.service</code> after file is created.</li>
<li>If unfamiliar with command line text editors, <code class="highlighter-rouge">sudo nano -w [filename]</code> can be used with <code class="highlighter-rouge">[filename]</code> replaced with the full path to the file. Ex. <code class="highlighter-rouge">sudo nano -w /etc/systemd/system/home-assistant@homeassistant.service</code>. After text entered, press CTRL-X then press Y to save and exit.</li>
