<p>The server project is the aggregation of these three sub projects</p>

<li><a href="/docs/wallet/wallet">Wallet</a></li>
<li><a href="/docs/chain/chain">Chain</a></li>
<li><a href="/docs/node/node">Node</a></li>

<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>If you would like to pass in a custom datadir for your server, you can do</p>
<pre><code class="hljs css language-bash">./app/server/target/universal/stage/bin/bitcoin-s-server --datadir /path/to/datadir/
</code></pre>
<p>To use a config file that is not the <code>bitcoin-s.conf</code> file in your datadir, you can do</p>
<pre><code class="hljs css language-bash">./app/server/target/universal/stage/bin/bitcoin-s-server --conf /path/to/file.conf
</code></pre>
<p>You can also pass in a custom <code>rpcport</code> to bind to</p>
<pre><code class="hljs css language-bash">./app/server/target/universal/stage/bin/bitcoin-s-server --rpcport 12345
</code></pre>
<p>For more information on configuring the server please see our <a href="/docs/config/configuration">configuration</a> document</p>
<p>For more information on how to use our built in <code>cli</code> to interact with the server please see <a href="/docs/applications/cli">/docs/applications/cli</a></p>
