title="1 基本的直接链接"></a></h2><ol><li><p><strong>为什么我们要使用 RocketMQ 而不是选择其他的产品？</strong></p><p>请参考<a href="http://rocketmq.apache.org/docs/motivation/" target="_blank" rel="noopener noreferrer">为什么要选择RocketMQ</a></p></li><li><p><strong>我是否需要安装其他的软件才能使用 RocketMQ ，例如 ZooKeeper ？</strong></p><p>不需要，RocketMQ 能够独立的运行。</p></li></ol><h2 class="anchor anchorWithStickyNavbar_LWe7" id="2-使用">2 使用<a href="#2-使用" class="hash-link" aria-label="2 使用的直接链接" title="2 使用的直接链接"></a></h2><ol><li><p><strong>新创建的 Consumer ID 从哪里开始消费消息？</strong></p><p>1）如果发送的消息在三天之内，那么消费者会从服务器中保存的第一条消息开始消费。</p><p>2）如果发送的消息已经超过三天，则消费者会从服务器中的最新消息开始消费，也就是从队列的尾部开始消费。</p><p>3）如果消费者重新启动，那么它会从最后一个消费位置开始消费消息。</p></li><li><p><strong>当消费失败的时候如何重新消费消息？</strong></p><p>1）在集群模式下，消费的业务逻辑代码会返回 Action.ReconsumerLater，NULL，或者抛出异常，如果一条消息消费失败，最多会重试 16 次，之后该消息会被丢弃。</p><p>2）在广播消费模式下，广播消费仍然保证消息至少被消费一次，但不提供重发的选项。</p></li><li><p><strong>当消费失败的时候如何找到失败的消息？</strong></p><p>1）使用按时间的主题查询，可以查询到一段时间内的消息。</p><p>2）使用主题和消息 ID 来准确查询消息。</p><p>3）使用主题和消息的 Key 来准确查询所有消息 Key 相同的消息。</p></li><li><p><strong>消息只会被传递一次吗？</strong></p><p>RocketMQ 确保所有消息至少传递一次。 在大多数情况下，消息不会重复。</p></li><li><p><strong>如何增加一个新的 Broker ？</strong></p><p>1）启动一个新的 Broker 并将其注册到NameServer 中的 Broker 列表里。</p><p>2）默认只自动创建内部系统 Topic 和 Consumer Group。 如果您希望在新节点上拥有您的业务主题和消费者组，请从现有的 Broker 中复制它们。 我们提供了管理工具和命令行来处理此问题。</p></li></ol><h2 class="anchor anchorWithStickyNavbar_LWe7" id="3-配置相关">3 配置相关<a href="#3-配置相关" class="hash-link" aria-label="3 配置相关的直接链接" title="3 配置相关的直接链接"></a></h2><p>以下回答均为默认值，可通过配置修改。</p><ol><li><p><strong>消息在服务器上可以保存多长时间？</strong></p><p>存储的消息将最多保存 3 天，超过 3 天未使用的消息将被删除。</p></li><li><p><strong>消息体的大小限制是多少？</strong></p><p>通常是256KB</p></li><li><p><strong>怎么设置消费者线程数？</strong></p><p>当你启动消费者的时候，可以设置 ConsumeThreadNums 属性的值，举例如下：</p><div class="language-java
