Question

我在我的cygwin控制台上启动了我的Zookeeper，并且它已成功启动 -

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

默认情况下将连接到运行在localhost：2181的ZooKeeper服务器，并将打开zk控制台。这就是我在控制台上得到的。我相信到现在一切都很好 -

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，或者我也帮忙然后按回车键但我的控制台上什么也没发生 -

见下文 -

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

在写完ls /并按下回车后，我的控制台中没有任何内容出现，同时也出现help ......这是我第一次和Zookeeper一起工作..有谁知道我错了什么我在这做什么？

更新： -

它在Windows命令提示符下工作正常但在CYGWIN中没有。我不知道为什么它在CYGWIN中不起作用..

Answer 1

我有同样的问题。这是我发现的。 Zookeeper使用jline为客户端执行花哨的东西（例如历史浏览等）。我发现你可以通过添加

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 $JVMFLAGS \
 org.apache.zookeeper.ZooKeeperMain "$@"

我仍然可以在windows cmd提示符下使用.cmd版本，如果我想要带有向上箭头的历史记录，但由于我总是在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应该可行。我没试过。

zkConsole在CYGWIN控制台中没有返回结果我的命令？
