20190311 Windows安装ZooKeeper

1. 说明

记录过程中踩过的坑

1.1. 环境

• 本机环境：Win10
• ZooKeeper版本：3.4.6

2. 安装

2.1. 下载

官网下载网址

2.2. 修改配置文件

1. 复制conf目录下的zoo_sample.cfg，修改名称为zoo.cfg
2. 按照本机安装路径修改zoo.cfg配置文件

dataDir=E:\\Develop\\zookeeper\\3.4.6\\zookeeper-3.4.6\\data
dataLogDir=E:\\Develop\\zookeeper\\3.4.6\\zookeeper-3.4.6\\log

1. 新建data和log文件夹，否则报错，报错信息为

PS E:\Develop\zookeeper\3.4.6\zookeeper-3.4.6> .\bin\zkServer.cmd

E:\Develop\zookeeper\3.4.6\zookeeper-3.4.6>java "-Dzookeeper.log.dir=E:\Develop\zookeeper\3.4.6\zookeeper-3.4.6\bin\.."

1. 启动ZooKeeper

启动命令：

PS E:\Develop\zookeeper\3.4.6\zookeeper-3.4.6> .\bin\zkServer.cmd

启动无异常信息

1. 客户端连接，验证启动成功

客户端连接命令：

PS E:\Develop\zookeeper\3.4.6\zookeeper-3.4.6> .\bin\zkCli.cmd -server 127.0.0.1:2181

命令行窗口显示：

[zk: 127.0.0.1:2181(CONNECTING) 0]

进行查询操作：

ls /

        at org.apache.zookeeper.ZooKeeperMain.run(ZooKeeperMain.java:323)
        at org.apache.zookeeper.ZooKeeperMain.main(ZooKeeperMain.java:282)

查询报错，因为是刚安装的，所以确认不会有什么问题，重启过服务之后再次尝试，响应正常

[zk: localhost:2181(CONNECTED) 1] ls /
[zookeeper]
