# **一、开发环境** #

下面列举我用到的环境和软件工具

*  win8
 *  jdk8
 *  idea 版本:ULTIMATE 2020.1
 *  tomcat 9.0.41
 *  zookeeper 3.6.2
 *  dubbo-admin 2.5x
 *  dubbo[2.5.3][] \+ springboot2

# 二、zookeeper 注册中心 #

## 2.1 简介 ##

ZooKeeper是一个分布式的，开放源码的分布式应用程序协调服务，是Google的Chubby一个开源的实现，是Hadoop和Hbase的重要组件。它是一个为分布式应用提供一致性服务的软件，提供的功能包括：配置维护、域名服务、分布式同步、组服务等。

## 2.2 下载 ##

### 2.2.1 选择版本 ###

[https://downloads.apache.org/zookeeper/][https_downloads.apache.org_zookeeper]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhenljaGVlcnVw_size_16_color_FFFFFF_t_70][]

### 2.2.2 [zookeeper-3.6.2][] 下载地址 ###

[https://downloads.apache.org/zookeeper/zookeeper-3.6.2/][zookeeper-3.6.2]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhenljaGVlcnVw_size_16_color_FFFFFF_t_70 1][]

## 2.3 解压部署 ##

### 2.3.1 解压后将config 目录下的 zoo\_sample.cfg 复制改名为 zoo.cfg ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhenljaGVlcnVw_size_16_color_FFFFFF_t_70 2][]

**备注：**

*  zoo.cfg配置文件可以配置zookeeper的端口，默认端口为：2181
 *  如果需要修改端口，可以修改zoo.cfg配置文件的
    
        initLimit=10
        # The number of ticks that can pass between 
        # sending a request and getting an acknowledgement
        syncLimit=5
        # the directory where the snapshot is stored.
        # do not use /tmp for storage, /tmp here is just 
        # example sakes.
        dataDir=/tmp/zookeeper
        # the port at which the clients will connect
        clientPort=2181
        # the maximum number of client connections.
        # increase this if you need to handle more clients
        #maxClientCnxns=60

## 2.4 启动zookeeper ##

windows 下面 双击 bin目录下的 zkServer.cmd

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhenljaGVlcnVw_size_16_color_FFFFFF_t_70 3][]

**备注：**

注：本文旨在介绍dubbo入门案例，zookeeper 这里只是最简单的单机使用，够下面dubbo入门案例的使用。

# 三、dubbo-admin的部署运行 #

## 3.1 简介 ##

简单来说，dubbo-admin 就是dubbo的管理控制台，通过可视化工具来方便我们管理每一个服务和每一个节点，可以查看管理提供者、消费者、注册的服务信息等等。

## 3.2 **在开发dubbo前先部署运行 dubbo-admin 的原因** ##

dubbo-admin 能够帮助我们直观的发现dubbo提供者和消费者是否注册成功、注册的服务是否一致等等，在我调试找错过程中帮了非常大的忙，所以呢，在这里我就先部署运行dubbo-admin。

## 3.3 下载、打包使用 ##

### 3.3.1 下载地址： ###

[https://github.com/apache/dubbo/tree/2.5.x][https_github.com_apache_dubbo_tree_2.5.x]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhenljaGVlcnVw_size_16_color_FFFFFF_t_70 4][]

**备注：**dubbo-admin还有其他版本，暂时没有尝试过，有兴趣的伙伴可以尝试一下其他版本

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhenljaGVlcnVw_size_16_color_FFFFFF_t_70 5][]

### 3.3.2 下载后的目录结构： ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhenljaGVlcnVw_size_16_color_FFFFFF_t_70 6][]

### 3.3.3 dubbo-admin打成war包 ###

核心打包命令：mvn package -Dmaven.test.skip=true

### 3.4.2 修改tomcat默认的8080端口 ###

修改tomcat安装目录下的conf文件夹下的server.xml文件

<Connector port="8089" protocol="HTTP/1.1"
                   connectionTimeout="20000"
                   redirectPort="8443" />

### 3.4.4 dubbo-admin登录账号说明 ###

备注一: 有2个账号 **账号root的密码是root , 账号guest的密码是guest** , 不要误以为只有1个账号 root/guest

备注二：如果需要编辑登录账号，可以修改在dubbo-admin-2.5.10.war下的\\WEB-INF\\dubbo.properties文件
