dubbo-Admin控制台+zookeeper环境搭建

  1. zookpeer搭建

    下载zookeeper-3.4.6，cd ./conf/   ,  cp   zoo_sample.cfg   zoo.cfg

    ./bin/zkServer.sh start 启动zookpeer服务

  2. dubboAdmain控制台搭建

    下载dubbo-admin.war,解压后放到tomcat的运行目录下，修改配置WEB-INF/dubbo.properties

    文件：

    dubbo.registry.address=zookeeper://192.168.1.201:2181，注意改成自己的地址
    dubbo.admin.root.password=root
    dubbo.admin.guest.password=guest

    这里，我们为一个应用发布两个提供者在不同的机器上，即使它们中有一台机器挂了，服务端也可以正常访问。

Hadoop学习笔记—14.ZooKeeper环境搭建

从字面上来看,ZooKeeper表示动物园管理员,这是一个十分奇妙的名字,我们又想起了Hadoop生态系统中,许多项目的Logo都采用了动物,比如Hadoop采用了大象的形象,所以我们可以猜测ZooKeep就是对这些动物进行一些管理工作的. 一.ZooKeeper基础介绍 1.1 动物园也要保障安全 zookeeper是hadoop下面的一个子项目,用来协调跟hadoop相关的一些分布式的框架,如hadoop, hive, pig等, 其实他们都是动物,所以叫zookeeper ——“动物园管理

Linux系统zookeeper环境搭建（单机、伪分布式、分布式）

本人现在对zookeeper的环境搭建做一个总结,一般zookeeper的安装部署可以有三种模式,单机模式.伪分布式和分布式,这三种模式在什么时候应用具体看大家的使用场景,如果你只有一台机器且只是想自己开发测试时用,你可以安装个单机模式,简单又实用.如果想装逼但又没有足够的机器,那你可以选择伪分布式的方式搭建,这可以满足你内心高大上的分布式需求又可以满足没有机器的屌丝现状.如果手头有三台以上的服务器,那就可以大展高富帅的风采,直接上真的分布式,真的分布式部署一般是在系统的正式环境中应用.下面我来

【Zookeeper】3.Zookeeper环境搭建1

之前我们讲解了Zookeeper的基本概念,下面我们来动手搭建Zookeeper的环境. 我们主要在本机上模拟集群环境,使用虚拟机,所以在开始搭建之前,我们要准备以下环境:(1)Vmware虚拟机(2)Linux操作系统:ubuntu16.4(3)SecureCRT(连接虚拟机) 步骤1.使用vmware创建三个ubuntu16.4的虚拟机我们要提前去下载虚拟机的系统安装文件,这里我使用的安装文件为:ubuntu-16.04-desktop-amd64.iso下面仅演示一个虚拟机的安装过程,一共
