linux下，zookeeper安裝並啟動起來了
DEMO時，JAVA控制台出現：

JVM采用了socket代理，不知道跟代理有沒有關系，安裝不是以ROOT用戶的
暫時沒解決，記錄下來先:
解決方案：
1.關閉防火牆。
通過zookeeper搭建dubbo注冊中心遇到的問題：在linux下安裝，配置並啟動zookeeper。在window環境下啟動服務提供方時，未成功啟動，報以下錯誤：

經檢查，是linux下防火牆未關閉，使用一下命令關閉防火牆:
servcie iptables stop
關閉后查看防火牆狀態
service –status-all
查看到一下信息則說明linux防火牆已經關閉。
2.可能是 客戶端 zookeper版本與服務器端安裝的zookeper版本不一致。
當關閉防火牆還是沒有解決問題時候，可以看看是否版本不一致，我的問題在關閉防火牆之后解決。
