我无法运行动物园管理员答案

【问题标题】：I can't run zookeeper我无法运行动物园管理员
【发布时间】：2017-09-03 18:25:45
【问题描述】：

我是卡夫卡世界的新手，我想启动 zookeeper 然后当我输入这个

bin/zookeeper-server-start.sh config/zookeeper.properties

我收到以下错误

ERROR Unexpected exception, exiting abnormally  (org.apache.zookeeper.server.ZooKeeperServerMain)
java.net.BindException: Address already in use

ERROR Unexpected exception, exiting abnormally (org.apache.zookeeper.server.ZooKeeperServerMain)
java.net.BindException: Address already in use

然后我尝试了netstat -nlp|grep 2181，但没有进程在运行

tcp        0      0 0.0.0.0:2181            0.0.0.0:*               LISTEN      -

请点灯

【解决方案1】：

现有的 Zookeeper 正在运行，我应该如何删除它。而不是阻止动物园管理员

bin/kafka-topics.sh --list --zookeeper localhost:2181 测试

【讨论】：

【解决方案2】：

重启kafka进程即可解决问题。

【讨论】：

【解决方案3】：

好像ZooKeeper的2181端口还在使用，请按照以下步骤解决这个问题：

使用 netstat 命令查找占用 2181 端口的进程。杀死正在使用 ZooKeeper 端口 2181 的进程：

$ netstat -antp | grep 2181
tcp        0      0 0.0.0.0:2181            0.0.0.0:*
LISTEN      28016/java <defunct>
$ kill -9 28016

【解决方案4】：

我遇到了同样的问题。我得到它是因为我的笔记本电脑崩溃导致 Zookeeper 服务器崩溃。我通过以下链接的帮助解决了。

How to recover Zookeeper from java.io.EOFException after a server crash?

我通过一一打开[Zookeper-data-dir]/zookeeper_0/version-2找到了有问题的日志文件。并找到了一个没有头或任何其他东西的日志文件。当我删除它时，我的问题解决了，我的 zookeeper 服务器开始正常运行。

也许你可以先停止你的 hbase。

就这样跟随..

【解决方案6】：

我已经通过执行以下命令解决了这个问题。

转到您安装的 kafka 文件夹并输入 sudo bin/zookeeper-server-stop.sh
bin/zookeeper-server-start.sh config/zookeeper.properties

我希望这会有所帮助。祝你好运！

【讨论】：

【解决方案7】：

首先，使用以下命令停止Zookeeper：

$ bin/zookeeper-server-stop.sh config/zookeeper.properties

然后，重新开始，你应该很高兴：

$ bin/zookeeper-server-start.sh config/zookeeper.properties

【讨论】：

【解决方案8】：

如果您正在运行命令 bin/zookeeper-server-start.sh config/zookeeper.properties

并得到错误：

  ERROR Unexpected exception, exiting abnormally (org.apache.zookeeper.server.ZooKeeperServerMain)
java.net.BindException: Address already in use
        at sun.nio.ch.Net.bind0(Native Method)

在这种情况下，您的虚拟机 端口 2181 已被 zookeeper 使用。

所以在 kafka zookeeper.properties 中将 clientPort 值更改为未使用的端口，例如 5181

再次运行命令，Zookeeper 将开始工作。

【讨论】：

【解决方案9】：

对于这种情况，你需要看看zookeeper是否在运行

使用下面的命令

sudo lsof -i :2181

你会得到

COMMAND   PID      USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
java     1005 zookeeper   33u  IPv6  17209      0t0  TCP *:2181 (LISTEN)
java     1005 zookeeper   34u  IPv6 327225      0t0  TCP localhost:2181->localhost:43566 (ESTABLISHED)
java    22585      root   88u  IPv6 324552      0t0  TCP localhost:43566->localhost:2181 (ESTABLISHED)

喜欢的说法。现在杀死动物园管理员重新开始。

sudo kill -9 1005

然后使用下面启动zookeeper

bin/zookeeper-server-start.sh config/zookeeper.properties

【讨论】：

【解决方案10】：

听起来 Zookeeper 服务器正在运行。

尝试：

bin/zkServer.sh stop 从 zookeeper 目录中将其关闭，然后：

bin/zookeeper-server-start.sh config/zookeeper.properties

来自kafka 目录

这解决了我的问题

【讨论】：

【解决方案11】：

使用此命令检查zookeeper 是否已在运行。

bin/kafka-topics.sh --list --zookeeper localhost:2181

检查您是否获得主题数量，如果您获得任何主题，则表示 Zookeeper 已经在运行。所以验证 Zookeeper 是否已经在运行。

【讨论】：

【解决方案12】：

使用端口 2181 肯定有一些陈旧的进程。我遇到了同样的问题。首先我检查了服务器的状态：

/usr/share/zookeeper$ bin/zkServer.sh status

或

/usr/share/zookeeper$ echo status | nc 127.0.0.1 2181

然后，我尝试启动 kafka，但失败并出现同样的错误。我更改了权限并以 sudo 身份运行..它也不起作用。因为我看不到任何使用该端口的进程。我重新启动了我的电脑，它工作了！！。

【讨论】：

【解决方案13】：

可能是另一个用户正在运行该进程。使用 jps 检查是否有任何具有 Quorum 的进程正在运行，将其杀死，然后尝试

【讨论】：

@Pandey 感谢您的回复，我尝试了您的建议，但没有运行 Quorum 进程
