均包括时间序列root.sg2.d0.s0, 若接收端先接收到发送端1的root.sg2.d0.s0的数据，那么接收端将拒绝发送端2的root.sg2同步的数据。</p> <h3 id="配置参数"><a href="#配置参数" class="header-anchor">#</a> 配置参数</h3> <h4 id="同步工具接收端"><a href="#同步工具接收端" class="header-anchor">#</a> 同步工具接收端</h4> <p>同步工具接收端的参数配置位于IoTDB的配置文件iotdb-engine.properties中，其安装目录为$IOTDB_HOME/conf/iotdb-engine.properties。在该配置文件中，有四个参数和同步接收端有关，配置说明如下:</p> <table><thead><tr><th>参数名</th> <th>is_sync_enable</th></tr></thead> <tbody><tr><td>描述</td> <td>同步功能开关，配置为true表示接收端允许接收同步的数据并加载，设置为false的时候表示接收端不允许接收同步的数据</td></tr> <tr><td>类型</td> <td>Boolean</td></tr> <tr><td>默认值</td> <td>false</td></tr> <tr><td>改后生效方式</td> <td>重启服务生效</td></tr></tbody></table> <table><thead><tr><th>参数名</th> <th>ip_white_list</th></tr></thead> <tbody><tr><td>描述</td> <td>设置同步功能发送端IP地址的白名单，以网段的形式表示，多个网段之间用逗号分隔。发送端向接收端同步数据时，只有当该发送端IP地址处于该白名单设置的网段范围内，接收端才允许同步操作。如果白名单为空，则接收端不允许任何发送端同步数据。默认接收端接受全部IP的同步请求。</td></tr> <tr><td>类型</td> <td>String</td></tr> <tr><td>默认值</td> <td>0.0.0.0/0</td></tr> <tr><td>改后生效方式</td> <td>重启服务生效</td></tr></tbody></table> <table><thead><tr><th>参数名</th> <th>sync_server_port</th></tr></thead> <tbody><tr><td>描述</td> <td>同步接收端服务器监听接口，请确认该端口不是系统保留端口并且未被占用。参数is_sync_enable设置为true时有效，参数is_sync_enable设置为false时无效</td></tr> <tr><td>类型</td> <td>Short Int : [0,65535]</td></tr> <tr><td>默认值</td> <td>5555</td></tr> <tr><td>改后生效方式</td> <td>重启服务生效</td></tr></tbody></table> <h4 id="同步工具发送端"><a href="#同步工具发送端" class="header-anchor">#</a> 同步工具发送端</h4> <p>同步功能发送端的参数配置在一个单独的配置文件中，其安装目录为<code>$IOTDB_HOME/conf/iotdb-sync-client.properties</code>。在该配置文件中，有五个参数和同步发送端有关，配置说明如下：</p> <table><thead><tr><th>参数名</th> <th>server_ip</th></tr></thead> <tbody><tr><td>描述</td> <td>同步接收端的IP地址</td></tr> <tr><td>类型</td> <td>String</td></tr> <tr><td>默认值</td> <td>127.0.0.1</td></tr> <tr><td>改后生效方式</td> <td>重启同步功能发送端生效</td></tr></tbody></table> <table><thead><tr><th>参数名</th> <th>server_port</th></tr></thead> <tbody><tr><td>描述</td> <td>同步接收端服务器监听端口，需要保证该端口和同步接收端配置的监听端口一致</td></tr> <tr><td>类型</td> <td>Short Int : [0,65535]</td></tr> <tr><td>默认值</td> <td>5555</td></tr> <tr><td>改后生效方式</td> <td>重启同步功能发送端生效</td></tr></tbody></table> <table><thead><tr><th>参数名</th> <th>sync_period_in_second</th></tr></thead> <tbody><tr><td>描述</td> <td>同步周期，两次同步任务开始时间的间隔，单位为秒(s)</td></tr> <tr><td>类型</td> <td>Int : [0,2147483647]</td></tr> <tr><td>默认值</td> <td>600</td></tr> <tr><td>改后生效方式</td> <td>重启同步功能发送端生效</td></tr></tbody></table> <table><thead><tr><th>参数名</th> <th>sync_storage_groups</th></tr></thead> <tbody><tr><td>描述</td> <td>进行同步的存储组列表，存储组间用逗号分隔；若列表设置为空表示同步所有存储组，默认为空</td></tr> <tr><td>类型</td> <td>String</td></tr> <tr><td>示例</td> <td>root.sg1, root.sg2</td></tr> <tr><td>改后生效方式</td> <td>重启同步功能发送端生效</td></tr></tbody></table> <table><thead><tr><th>参数名</th> <th>max_number_of_sync_file_retry</th></tr></thead> <tbody><tr><td>描述</td> <td>发送端同步文件到接收端失败时的最大重试次数</td></tr> <tr><td>类型</td> <td>Int : [0,2147483647]</td></tr> <tr><td>示例</td> <td>5</td></tr> <tr><td>改后生效方式</td> <td>重启同步功能发送端生效</td></tr></tbody></table> <h3 id="使用方式"><a href="#使用方式" class="header-anchor">#</a> 使用方式</h3> <h4 id="启动同步功能接收端"><a href="#启动同步功能接收端" class="header-anchor">#</a> 启动同步功能接收端</h4> <ol><li>配置接收端的参数，例如：</li></ol> <div class="language- line-numbers-mode"><pre class="language-text"><code>	####################
