<p>I use this for my Telegram bot (<a href="https://t.me/ashleybot">@AshleyBot</a>) but it can run any other program. Create file <code style="padding:0">/etc/systemd/system/yourbot.service</code>:</p>
<pre><code>[Unit]
Description=Chat bot
[Service]
User=username
WorkingDirectory=/path/to/your/bot
ExecStart=/path/to/your/bot/bot.py
Restart=always
[Install]
WantedBy=multi-user.target</code></pre>
<p>Execute:</p>
<pre><code>systemctl daemon-reload
systemctl start yourbot.service</code></pre>
<p>It should autorestarts if bot crashes and autorunning if server restarts</p>
