<p>You can build the server with the <a href="https://github.com/sbt/sbt-native-packager">sbt native packager</a>.
The native packager offers <a href="https://github.com/sbt/sbt-native-packager#examples">numerous ways to package the project</a>.</p>
<p>In this example we are going to use <code>stage</code> which will produce bash scripts we can easily execute. You can stage the server with the following command.</p>
<pre><code class="hljs css language-bash">sbt appServer/universal:stage
</code></pre>
<p>This will produce a script to execute bitcoin-s which you can start with</p>
<pre><code class="hljs css language-bash">./app/server/target/universal/stage/bin/bitcoin-s-server
</code></pre>

<p>For server side installation you'll need to install a Java Virtual Machine first.</p>
<pre><code class="hljs css language-bash">sudo apt install openjdk-11-jdk-headless
</code></pre>
<p>Then build a Bitcoin-S server as described above and copy it into <code>/usr/local</code>:</p>
<pre><code class="hljs css language-bash">sudo cp -r app/server/target/universal/stage /usr/<span class="hljs-built_in">local</span>/bitcoin-s
sudo chmod +x /usr/<span class="hljs-built_in">local</span>/bitcoin-s/bin/bitcoin-s-server
</code></pre>
<p>The server process will run in the background and use a separate user for security reasons.
This user does not have admin rights and cannot change the system configuration.</p>
<pre><code class="hljs css language-bash">sudo adduser bitcoins
</code></pre>
<p>In this case you'll need to put the config file into <code>/home/bitcoins/.bitcoin-s/bitcoin-s.conf</code>.</p>
<p>To start the server as a daemon on system startup we'll need to configure a <code>systemd</code> service.
Create <code>bitcoin-s.service</code> file using your favorite text editor.</p>
<pre><code class="hljs css language-bash">sudo nano /etc/systemd/system/bitcoin-s.service
