<p>三种配置项的配置文件均位于IoTDB安装目录：<code>$IOTDB_HOME/conf</code>文件夹下,其中涉及server配置的共有4个文件，分别为：<code>iotdb-cluster.properties</code>、<code>iotdb-engine.properties</code>、<code>logback.xml</code> 和 <code>iotdb-env.sh</code>(Unix系统)/<code>iotdb-env.bat</code>(Windows系统), 您可以通过更改其中的配置项对系统运行的相关配置项进行配置。</p> <p>配置文件的说明如下：</p> <ul><li><p><code>iotdb-env.sh</code>/<code>iotdb-env.bat</code>：环境配置项的默认配置文件。您可以在文件中配置JAVA-JVM的相关系统配置项。</p></li> <li><p><code>iotdb-engine.properties</code>：IoTDB引擎层系统配置项的默认配置文件。您可以在文件中配置IoTDB引擎运行时的相关参数。此外，用户可以在文件中配置IoTDB存储时TsFile文件的相关信息，如每次将内存中的数据写入到磁盘前的缓存大小(<code>group_size_in_byte</code>)，内存中每个列打一次包的大小(<code>page_size_in_byte</code>)等。</p></li> <li><p><code>logback.xml</code>: 日志配置文件，比如日志级别等。</p></li> <li><p><code>iotdb-cluster.properties</code>: IoTDB集群所需要的一些配置。</p></li></ul> <p><code>iotdb-engine.properties</code>、<code>iotdb-env.sh</code>/<code>iotdb-env.bat</code> 两个配置文件详细说明请参考<a href="/zh/UserGuide/Master/Appendix/Config-Manual.html">附录/配置手册</a>，下面描述的配置项是在<code>iotdb-cluster.properties</code>文件中的，也可以直接查看<a
