20190311 Windows安裝ZooKeeper

1. 說明

記錄過程當中踩過的坑

1.1. 環境

• 本機環境：Win10
• ZooKeeper版本：3.4.6

2. 安裝

2.1. 下載

官網下載網址

2.2. 修改配置文件

1. 複製conf目錄下的zoo_sample.cfg，修更名稱爲zoo.cfg
2. 按照本機安裝路徑修改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文件夾，不然報錯，報錯信息爲

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\.."

E:\Develop\zookeeper\3.4.6\zookeeper-3.4.6>endlocal

1. 啓動ZooKeeper

啓動命令：

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

啓動無異常信息

1. 客戶端鏈接，驗證啓動成功

客戶端鏈接命令：

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

命令行窗口顯示：

[zk: 127.0.0.1:2181(CONNECTING) 0]

進行查詢操做：

ls /

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

查詢報錯，由於是剛安裝的，因此確認不會有什麼問題，重啓過服務以後再次嘗試，響應正常

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