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/Dockerfile" target="_blank" rel="noopener noreferrer">https://github.com/apache/iotdb/blob/master/docker/Dockerfile</a></li></ul><h3 id="prerequisites" tabindex="-1"><a class="header-anchor" href="#prerequisites"><span>Prerequisites</span></a></h3><p>To use IoTDB, you need to have:</p><ol><li>Java >= 1.8 (Please make sure the environment path has been set)</li><li>Maven >= 3.6 (Optional)</li><li>Set the max open files num as 65535 to avoid "too many open files" problem.</li></ol><blockquote><p>Note: If you don't have maven installed, you should replace 'mvn' in the following commands with 'mvnw' or 'mvnw.cmd'.</p><h3 id="installation-from-binary-files" tabindex="-1"><a class="header-anchor" href="#installation-from-binary-files"><span>Installation from binary files</span></a></h3></blockquote><p>You can download the binary file from:<br><a href="https://iotdb.apache.org/Download/" target="_blank" rel="noopener noreferrer">Download page</a></p><h3 id="installation-from-source-code" tabindex="-1"><a class="header-anchor" href="#installation-from-source-code"><span>Installation from source code</span></a></h3><p>You can get the released source code from <a href="https://iotdb.apache.org/Download/" target="_blank" rel="noopener noreferrer">https://iotdb.apache.org/Download/</a>, or from the git repository <a href="https://github.com/apache/iotdb/tree/master" target="_blank" rel="noopener noreferrer">https://github.com/apache/iotdb/tree/master</a><br> You can download the source code from:</p><div class="language-text line-numbers-mode" data-highlighter="prismjs" data-ext="text" data-title="text"><pre><code><span class="line">git clone https://github.com/apache/iotdb.git</span> |

If you want to build the version that we have released, you need to create and check out a new branch by command <code>git checkout -b my_{project.version} v{project.version}</code>. E.g., you want to build the version <code>0.12.4</code>, you can execute this command to make it:</p><div class="language-bash line-numbers-mode" data-highlighter="prismjs" data-ext="sh" data-title="sh"><pre><code><span class="line"><span class="token operator">></span> <span class="token function">git</span> checkout <span class="token parameter variable">-b</span> my_0.12.4 v0.12.4</span> |
