For a more-complete guide, please visit our website’s documents.</p> <h2 id="prerequisites"><a href="#prerequisites" class="header-anchor">#</a> Prerequisites</h2> <p>To use IoTDB, you need to have:</p> <ol><li>Java &gt;= 1.8 (Please make sure the environment path has been set)</li> <li>Maven &gt;= 3.0 (If you want to compile and install IoTDB from source code)</li></ol> <h2 id="installation"><a href="#installation" class="header-anchor">#</a> Installation</h2> <p>IoTDB provides you two installation methods, you can refer to the following suggestions, choose one of them:</p> <ul><li>Installation from source code. 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.(Comming Soon...)</li></ul> <p>Here in the Quick Start, we give a brief introduction of using source code to install IoTDB. For further information, please refer to Chapter 4 of the User Guide.</p> <h3 id="installation-from-source-code"><a href="#installation-from-source-code" class="header-anchor">#</a> Installation from source code</h3> <p>You can get the released source code from https://iotdb.apache.org/Download/, or from the git repository https://github.com/apache/incubator-iotdb/tree/master</p> <p>Now suppose your directory is like this:</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>&gt; pwd

then by default <code>IOTDB_HOME</code> is the direct parent directory of <code>sbin/start-server.sh</code> on Unix/OS X
(or that of <code>sbin\start-server.bat</code> on Windows).</p></li> <li><p>if <code>IOTDB_CLI_HOME</code> is not explicitly assigned,

&gt; rm -rf $IOTDB_HOME/lib/
</code></pre> <div class="line-numbers-wrapper"><span class="line-number">1</span><br><span class="line-number">2</span><br></div></div><p>Then under the root path of incubator-iotdb, you can build IoTDB using Maven:</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>&gt; pwd
