Java连接Zookeeper 一.配置zk环境 本人使用的是虚拟机,创建了两台linux服务器(安装过程百度上很多) 准备zk的安装包,zookeeper-3.4.10.tar.gz,可在Apache官网下载,这里我提供了一个百度云的https://pan.baidu.com/s/15icVROSKpgwUzqzpHW6Rbg 密码dgnp 安装过程 环境准备:安装JDK,配置Hosts,配置Hostname.关闭防火墙 $ZOOKEEPER = /home/zookeeper_applica…

Java服务端连接Zookeeper,进行节点信息的获取,管理…,整理成一个基本工具, 添加依赖: <dependency> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> <version>3.3.6</version> </dependency> package com; import java.util.…

Java操作Zookeeper很简单,但是前提要把包导对. 关于Zookeeper的Linux环境搭建可以参考我的这篇博客:Linux环境下Zookeeper安装 下面进入正题: 一.导入依赖 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http:…

代码很简单: public static void main(String[] args) { Jedis jedis = new Jedis("116.85.10.216",6379); System.out.println(jedis.ping()); } 异常代码: redis.clients.jedis.exceptions.JedisConnectionException: java.net.SocketTimeoutException: Read timed out 当出现…

public class Demo2 { public static void main(String[] args) { String connectString = "192.168.168.133:2181"; int sessionTimeout = 500000; // 会话时间.设置长一点,如果不够长,则会connect loss try { // 建立zookeeper链接 ZooKeeper zk = new ZooKeeper(connectString, sessi…
