如何从命令提示符检查 ZooKeeper 是否正在运行或启动? [英] How to check if ZooKeeper is running or up from command prompt?

问题描述

我探索了一些设置 kafka 的选项，我知道 Zookeeper 必须启动并运行才能启动 kafka.

I exploring a few options to setup kafka and I knew that the Zookeeper has to be up and running to initiate a kafka.

我想知道如何找到以下内容.

I would like to know how can I find the below.

1)我的zookeeper实例的主机名和端口---我检查了zoo.cfg，我只能找到ClientPort而不是主机名，主机名会是我的机器的主机名吗??

1) hostname and port for my zookeeper instance---I checked the zoo.cfg and I could only find the ClientPort not the hostname, will hostname be the hostname of my box??

2) 要检查 ZooKeeper 是否已启动并正在运行---我尝试执行 ps -ef |grep "zoo" 我找不到任何东西.可能是我用错关键词搜索??

2) To check if ZooKeeper is up and running---I tried to do a ps -ef | grep "zoo" I could not find anything. May be I am using a wrong key word to search??

真的很感激任何帮助吗?

Any help would be really appreciated?
