我正在尝试使用下面的配置设置一个zookeeper实例，但是开始日志表明zookeeper在尝试绑定端口2181时暂停。可以在这里告诉我一些问题。谢谢。

我建议您从配置文件中删除以下行
server.1=localhost:2888:3888
然后重新启动服务器。

在CentOS上，您可以编辑以下文件并为_JAVA_OPTIONS添加行
sudo vim /etc/default/zookeeper
导出_JAVA_OPTIONS =“-Djava.net.preferIPv4Stack = true”
然后重新启动过程
sudo service zookeeper-server restart

我想提一下，当您收到以下日志消息时，这意味着服务器实际上已启动。
INFO [main:NIOServerCnxnFactory@94] - binding to port 0.0.0.0/0.0.0.0:2181
如果您有一个如下所示的单个zookeeper实例，您看到的ERROR消息实际上是一个警告而不是错误。
2014-07-18 16:00:48,980 [myid:] - ERROR [main:QuorumPeerConfig@289] - Invalid configuration, only one server specified (ignoring)

尝试将此添加到zoo.cfg中
quorumListenOnAllIPs=true

你在Windows 64位上运行zookeeper吗？我遇到了同样的问题，但后来发现Win64不受支持。请参阅Zookeeper链接http://zookeeper.apache.org/doc/r3.4.5/zookeeperAdmin.html#sc_supportedPlatforms
