Question

我正在努力解决一个非常奇怪的问题。之前没有任何问题。

我必须启动Zookeeper和Kafka。为此，我执行以下操作：

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

此后，当我运行jps命令时：我可以看到QuaorumPeerMain是一个用于Zookeeper的进程。

现在我跑步 2. nohup bin / kafka-server-start.sh config / server.properties＆

此后，当我运行JPS时，zookeeper的进程也消失了，它会自动关闭。

我不是要弄清楚为什么突然出现的表。请看看并帮助我。

Answer 1

如果您仔细查看日志，特别是java.io.FileNotFoundException: /tmp/zookeeper/version-2/log.181 (Permission denied)，它将讨论dataDir目录权限更改。仅供参考，dataDir是您在zookeeper.properties中指定的目录快照，在您的情况下，我猜它是：/tmp/zookeeper/...。

您可以检查linux / putty上授予此文件夹哪些权限，看起来权限已更改，这引起了上述问题。让我知道这是否对您有用。谢谢！

Answer 2

停止动物园管理员。
删除zookeeper和kafka的所有日志。

一旦我为kafka服务器运行命令，Zookeeper就会自动关闭
