通過命令zkServer.sh start之后，顯示STARTED

通過client測試報錯? 無法連接?連接關閉

我就很納悶明明已經(jīng)啟動為啥查看狀態(tài)報這個錯呢

Error contacting service. It is probably not running

問題分析

我們可以通過bin目錄下面的zookeeper.out來查看問題原因

為啥連接被拒絕

其實這個本身沒有問題，因為這是集群的，要全部啟動起來才能選舉leader?follower?observer? 因為還有兩臺沒有啟動?所以不能進行通信選舉，我們只需要將另外兩臺啟動起來就可以了

這個其實沒有問題的，我以前的文章也寫過，只是時間久了忘記了

這個以前集群安裝啟動的文章分布式Zookeeper安裝搭建詳解_ywl470812087的博客-CSDN博客

里面有個細節(jié)在第七步驟中?每臺機器上分別啟動，哎到這里我覺得自己太粗心大意，不知道各位有沒有這樣的情況，不知道這篇文章能不能幫到你

總結

以上是生活随笔為你收集整理的zookeeper Error contacting service. It is probably not running的全部內(nèi)容，希望文章能夠幫你解決所遇到的問題。
