我像这样在我的cygwin控制台上启动了我的Zookeeper，它成功启动了 -

username@00542612 ~
$ zkServer.sh start
JMX enabled by default
Using config: C:\ApacheZookeeper\zookeeper-3.4.5\conf\zoo.cfg
Starting zookeeper ... STARTED

现在，在连接到 ZooKeeper 之后。我打开了一个新的 Cygwin 窗口，并发出以下命令

$ zkCli.sh

它将默认连接到运行在 localhost:2181 的 ZooKeeper 服务器，并打开 zk 控制台。这就是我在控制台上得到的。我相信直到现在一切都很好——

username@00542612 ~
$ zkCli.sh

WATCHER::

WatchedEvent state:SyncConnected type:None path:null
[zk: localhost:2181(CONNECTED) 0]

现在我试图ls /查看我一般有多少个节点，或者我也提供帮助，然后按 Enter 键，但我的控制台上没有发生任何事情 -

见下文 -

WatchedEvent state:SyncConnected type:None path:null
[zk: localhost:2181(CONNECTED) 0] ls /

写完后ls / 按回车键，我的控制台上什么也没有出现，同样help...这是我第一次与 Zookeeper 合作。有谁知道我在这里做错了什么？

更新：-

它在 Windows 命令提示符下工作正常，但在 CYGWIN 中不能正常工作。我不确定为什么它在 CYGWIN 中不能工作。

我遇到过同样的问题。这就是我发现的。Zookeeper 使用 jline 为客户端做一些花哨的事情（例如历史浏览等）。我发现您可以通过添加来配置 jline

-Djline.terminal=jline.UnixTerminal

到你的 zkCli.sh 文件这是我的样子：

"$JAVA" "-Dzookeeper.log.dir=${ZOO_LOG_DIR}" "-Dzookeeper.root.logger=${ZOO_LOG4J_PROP}" \
 -Djline.terminal=jline.UnixTerminal \
 -cp "$CLASSPATH" $CLIENT_JVMFLAGS $JVMFLAGS \
 org.apache.zookeeper.ZooKeeperMain "$@"

如果我想要带有向上箭头的历史记录，我仍然可以在 Windows cmd 提示符下使用 .cmd 版本，但是由于我总是在 cygwin 中，这对我来说很好。

编辑：

您也可以简单地设置 CLIENT_JVMFLAGS。

此外，在阅读了 zookeeper 的代码后，从 lib 中删除 jline*.jar 应该可以工作。我没有尝试这个。
