我正在尝试使用下面的配置设置一个单独的zookeeper示例，但是启动日志显示zookeeper在尝试绑定端口2181时停止。有人能告诉我这里的问题吗？谢谢。

我建议您从配置文件中删除以下行
然后重新启动服务器。
hi3rlvi22#
在CentOS上，您可以编辑以下文件并添加_JAVA_OPTIONS行
导出_JAVA_OPTIONS="-Djava.net.preferIPv4堆栈=真”
然后重新启动过程

如果您正在为测试/开发运行一个独立的zookeeper，请在
zoo.cfg中注解此行：#server.1=localhost:2888:3888然后，改为：
错误[main：QuorumPeerConfig@289] -配置无效，仅指定了一个服务器（忽略）
您将看到：
警告[main：QuorumPeerMain@125] -配置中未定义配置或仲裁，正在以独立模式运行
Reference：
服务器.1 =缩放1：2888：3888
服务器.2 =缩放2：2888：3888
服务器.3 =缩放3：2888：3888
server.X格式的条目列出了组成ZooKeeper服务的服务器。当服务器启动时，它通过在数据目录中查找文件myid来知道它是哪个服务器。该文件包含ASCII格式的服务器编号。
最后，请注意每个服务器名称后面的两个端口号：“2888”和“3888”。对等体使用前一个端口连接到其他对等体。这样的连接是必要的，以便对等体可以通信，例如，同意更新的顺序。更具体地说，ZooKeeper服务器使用此端口将跟随者连接到领导者。当新领导者出现时，跟随者使用此端口打开到领导者的TCP连接。2因为默认领导者选举也使用TCP，我们当前需要另一个端口用于领导者选举。3这是服务器条目中的第二个端口。

我的配置文件（zoo.cfg）在单一模式下是在这里，它的工作正常：

我想指出的是，当您收到以下日志消息时，这意味着服务器实际上已经启动。
同样，如果你有一个单一的zookeeper示例，你看到的错误消息实际上是一个警告，而不是一个错误。

尝试将此文件添加到zoo.cfg

您是否在Windows 64位上运行Zookeeper？我也遇到了同样的问题，但后来发现不支持Win64。请参见Zookeeper链接http://zookeeper.apache.org/doc/r3.4.5/zookeeperAdmin.html#sc_supportedPlatforms
