<p>You can easily create a unit file for calibre to run on boot on a modern (systemd) based Linux system. This means it will also restart after a crash. Create the file <code>/etc/systemd/system/calibre-server.service</code> with the contents shown below:
|
|
|
</p>
|
|
|
<pre>[Unit]
|
|
|
Description=Calibre.
|
|
|
After=syslog.target network.target
|
|
|
|
|
|
[Service]
|
|
|
Type=simple
|
|
|
User=pi
|
|
|
Group=pi
|
|
|
WorkingDirectory=/home/pi/calibre-web
|
|
|
ExecStart=python cps.py
|
|
|
Restart=always
|
|
|
|
|
|
[Install]
|
|
|
WantedBy=multi-user.target</pre>
|
|
|
<p>The <code>User</code> and <code>Group</code> should be the same ones that own the files in the calibre library directory. It's generally not a good idea to run the server as root. Also change the path to the calibre library directory to suit your system.

<p>The calibre server does not need a running X server, but it does need the X libraries installed as some components it uses link against them.
|
|
|
</p><p>The calibre server also supports systemd socket activation, so you can use that, if needed, as well.
