If you need to modify the code yourself, you can use this method.</li><li>Installation from binary files. Download the binary files from the official website. This is the recommended method, in which you will get a binary released package which is out-of-the-box.</li><li>Using Docker：The path to the dockerfile is <a href="https://github.com/apache/iotdb/blob/master/docker/src/main" target="_blank" rel="noopener noreferrer">github<span><svg class="external-link-icon" xmlns="http://www.w3.org/2000/svg" aria-hidden="true" focusable="false" x="0px" y="0px" viewBox="0 0 100 100" width="15" height="15"><path fill="currentColor" d="M18.8,85.1h56l0,0c2.2,0,4-1.8,4-4v-32h-8v28h-48v-48h28v-8h-32l0,0c-2.2,0-4,1.8-4,4v56C14.8,83.3,16.6,85.1,18.8,85.1z"></path><polygon fill="currentColor" points="45.7,48.7 51.3,54.3 77.2,28.5 77.2,37.2 85.2,37.2 85.2,14.9 62.8,14.9 62.8,22.9 71.5,22.9"></polygon></svg><span class="external-link-icon-sr-only">open in new window</span></span></a></li></ul><h3 id="download" tabindex="-1"><a class="header-anchor" href="#download" aria-hidden="true">#</a> Download</h3><p>You can download the binary file from:<br><a href="https://iotdb.apache.org/Download/" target="_blank" rel="noopener noreferrer">Download Page<span><svg class="external-link-icon" xmlns="http://www.w3.org/2000/svg" aria-hidden="true" focusable="false" x="0px" y="0px" viewBox="0 0 100 100" width="15" height="15"><path fill="currentColor" d="M18.8,85.1h56l0,0c2.2,0,4-1.8,4-4v-32h-8v28h-48v-48h28v-8h-32l0,0c-2.2,0-4,1.8-4,4v56C14.8,83.3,16.6,85.1,18.8,85.1z"></path><polygon fill="currentColor" points="45.7,48.7 51.3,54.3 77.2,28.5 77.2,37.2 85.2,37.2 85.2,14.9 62.8,14.9 62.8,22.9 71.5,22.9"></polygon></svg><span class="external-link-icon-sr-only">open in new window</span></span></a></p><h3 id="configurations" tabindex="-1"><a class="header-anchor" href="#configurations" aria-hidden="true">#</a> Configurations</h3><p>Configuration files are under "conf" folder</p><ul><li>environment config module (<code>datanode-env.bat</code>, <code>datanode-env.sh</code>),</li><li>system config module (<code>iotdb-datanode.properties</code>)</li><li>log config module (<code>logback.xml</code>).</li></ul><p>For more, see <a href="/UserGuide/Master/Reference/DataNode-Config-Manual.html" class="">Config</a> in detail.</p><h3 id="start" tabindex="-1"><a class="header-anchor" href="#start" aria-hidden="true">#</a> Start</h3><p>You can go through the following step to test the installation, if there is no error after execution, the installation is completed.</p><h4 id="start-iotdb" tabindex="-1"><a class="header-anchor" href="#start-iotdb" aria-hidden="true">#</a> Start IoTDB</h4><p>IoTDB is a database based on distributed system.
