java - Zookeeper Ensemble 不响应客户端？

Question

我是 Zookeeper 的新手，正在我的系统中使用 Zookeeper Ensemble 设置 Solr Cloud，当我尝试同时运行所有 Zookeeper 时出现问题，三个 Zookeeper 在三个单独的端口上运行并将它们指向我的 Solr安装在 Apache Tomcat 服务器上。配置文件如下:-

zoo1.cfg

tickTime=2000
dataDir=/Users/prime/Desktop/Deployment Docs/Zookeeper/data
clientPort=2181
initLimit=5
syncLimit=2
server.1=localhost:8002:3888
server.2=localhost:8005:3889
server.3=localhost:8008:3890

zoo2.cfg

tickTime=2000
dataDir=/Users/prime/Desktop/Deployment Docs/Zookeeper/data
clientPort=2182
initLimit=5
syncLimit=2
server.1=localhost:8002:3888
server.2=localhost:8005:3889
server.3=localhost:8008:3890

zoo3.cfg

tickTime=2000
dataDir=/Users/prime/Desktop/Deployment Docs/Zookeeper/data
clientPort=2183
initLimit=5
syncLimit=2
server.1=localhost:8002:3888
server.2=localhost:8005:3889
server.3=localhost:8008:3890

在此之后，当我尝试在 2181 连接服务器时。使用 ./zkCli 它给了我以下错误:-

sh-3.2#./zkCli.sh

我的问题是出了什么问题以及如何解决这个问题。因为无论如何我都无法纠正它。

首先，您应该为每个 zookeeper 实例设置单独的数据目录。在数据目录中创建一个名为 myid 的文件。在这些文件中，根据服务器只写 1、2 或 3(例如，对于 server1 写 1)。请check here

然后启动您的动物园管理员合奏。
