一。安装zookeeper

　　1. 进入阿里云的容器服务，搜索zookeeper：https://cr.console.aliyun.com/cn-hangzhou/images

　　2. 复制网址

　　3. 下载镜像

[root@ay120tum0is24xe ~]# docker image listREPOSITORY          TAG                 IMAGE ID            CREATED             SIZEmysql               5.6                 27e29668a08a        6 weeks ago         256MB[root@ay120tum0is24xe ~]# docker image pull registry.cn-hangzhou.aliyuncs.com/zuowenbo/zookeeperUsing default tag: latestlatest: Pulling from zuowenbo/zookeeper8e3ba11ec2a2: Pull complete 311ad0da4533: Pull complete 391a6a6b3651: Pull complete 1e5180f6c6f9: Pull complete Digest: sha256:d7531d8bec4b2f2a298fceaaaaeac8f5c7d223d4a9ea2136cf0af23110c83ae8Status: Downloaded newer image for registry.cn-hangzhou.aliyuncs.com/zuowenbo/zookeeper:latest[root@ay120tum0is24xe ~]# docker image list -aREPOSITORY                                             TAG                 IMAGE ID            CREATED             SIZEmysql                                                  5.6                 27e29668a08a        6 weeks ago         256MBregistry.cn-hangzhou.aliyuncs.com/zuowenbo/zookeeper   latest              64e049ee9478        6 months ago        148MB[root@ay120tum0is24xe ~]#

　　4. 修改镜像名称

[root@ay120tum0is24xe ~]# docker image tag registry.cn-hangzhou.aliyuncs.com/zuowenbo/zookeeper:latest zookeeper:latest[root@ay120tum0is24xe ~]# docker image list -aREPOSITORY                                             TAG                 IMAGE ID            CREATED             SIZEmysql                                                  5.6                 27e29668a08a        6 weeks ago         256MBregistry.cn-hangzhou.aliyuncs.com/zuowenbo/zookeeper   latest              64e049ee9478        6 months ago        148MBzookeeper                                              latest              64e049ee9478        6 months ago        148MB[root@ay120tum0is24xe ~]# docker image rm registry.cn-hangzhou.aliyuncs.com/zuowenbo/zookeeper:latestUntagged: registry.cn-hangzhou.aliyuncs.com/zuowenbo/zookeeper:latestUntagged: registry.cn-hangzhou.aliyuncs.com/zuowenbo/zookeeper@sha256:d7531d8bec4b2f2a298fceaaaaeac8f5c7d223d4a9ea2136cf0af23110c83ae8[root@ay120tum0is24xe ~]# docker image list -aREPOSITORY          TAG                 IMAGE ID            CREATED             SIZEmysql               5.6                 27e29668a08a        6 weeks ago         256MBzookeeper           latest              64e049ee9478        6 months ago        148MB[root@ay120tum0is24xe ~]#

　　5. 启动容器

[root@ay120tum0is24xe ~]# docker container run --name zookeeper001 -d -p 2181:2181 zookeeper:latest    // 后面的为容器里的端口838d94a2d1c7120639c4d8219d26e718330d11a93e3e3989027a4ce61c7f32d4[root@ay120tum0is24xe ~]# docker container run --name zookeeper002 -d -p 2182:2181 zookeeper:latestdf4357e92486490918c5a63ab7adec038eb5beddb8d1d42a04a8c9041df9fadf[root@ay120tum0is24xe ~]# docker container listCONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                             PORTS                                        NAMESdf4357e92486        zookeeper:latest    "/opt/zookeeper/bin/…"   19 seconds ago      Up 18 seconds (health: starting)   2888/tcp, 3888/tcp, 0.0.0.0:2182->2181/tcp   zookeeper002838d94a2d1c7        zookeeper:latest    "/opt/zookeeper/bin/…"   38 seconds ago      Up 37 seconds (healthy)            2888/tcp, 0.0.0.0:2181->2181/tcp, 3888/tcp   zookeeper001[root@ay120tum0is24xe ~]#

--name：容器名称

-d：后台运行

-p：端口映射，冒号左边为主机端口，右边为容器端口　　

　　6. 进人容器zookeeper002

[root@ay120tum0is24xe ~]# docker container exec -it zookeeper002 /bin/sh/opt/zookeeper # lsLICENSE.txt                build.xml                  ivy.xml                    zookeeper-3.4.13.jarNOTICE.txt                 conf                       ivysettings.xml            zookeeper-3.4.13.jar.ascREADME.md                  contrib                    lib                        zookeeper-3.4.13.jar.md5README_packaging.txt       dist-maven                 recipes                    zookeeper-3.4.13.jar.sha1bin                        docs                       src/opt/zookeeper #

　　7.通过主机登录容器zookeeper001

/opt/zookeeper # ./bin/zkCli.sh -server 10.20.0.128:2181[zk: 10.20.0.128:2181(CONNECTED) 0]

　　8. quit退出zookeeper001，exit 退出容器zookeeper002

二。安装dubbo-admin

　　1. 下载镜像

[root@ay120tum0is24xe ~]# docker image pull registry.cn-hangzhou.aliyuncs.com/zhaozhiwu/dubbo-admin[root@ay120tum0is24xe ~]# docker image listREPOSITORY                                                TAG                 IMAGE ID            CREATED             SIZEregistry.cn-hangzhou.aliyuncs.com/zhaozhiwu/dubbo-admin   latest              4b43bc0f997e        3 weeks ago         360MBmysql                                                     5.6                 27e29668a08a        6 weeks ago         256MBzookeeper                                                 latest              64e049ee9478        6 months ago        148MB[root@ay120tum0is24xe ~]# docker image tag registry.cn-hangzhou.aliyuncs.com/zhaozhiwu/dubbo-admin dubbo-admin:latest[root@ay120tum0is24xe ~]# docker image rm registry.cn-hangzhou.aliyuncs.com/zhaozhiwu/dubbo-adminUntagged: registry.cn-hangzhou.aliyuncs.com/zhaozhiwu/dubbo-admin:latestUntagged: registry.cn-hangzhou.aliyuncs.com/zhaozhiwu/dubbo-admin@sha256:f23d8276e94ccfc5a6e5565ba6744c07f432869667fd08420d58148baf863910[root@ay120tum0is24xe ~]# docker image listREPOSITORY          TAG                 IMAGE ID            CREATED             SIZEdubbo-admin         latest              4b43bc0f997e        3 weeks ago         360MBmysql               5.6                 27e29668a08a        6 weeks ago         256MBzookeeper           latest              64e049ee9478        6 months ago        148MB[root@ay120tum0is24xe ~]#

　　2. 运行容器

[root@192 ~]# docker run -d --add-host zk:10.20.0.129 -p 8090:8080 --name dubbo dubbo-admin2e164333536a5b3c15260270e3939e9064cc11087824aaeac8bfbe379fea882c[root@192 ~]#

　　3. 浏览器登录：http://10.20.0.129:8090/ ，用户：root ，密码：root

三。新建项目

　　1. 建立空项目

　　2. 添加maven父工程，不用模板，工程名：parent

　　3. 修改 pom.xml

　　4. 先点击library，然后点击File-->new-->module，建立maven web工程：dubboxDemo-Service (服务提供者)，并继承父工程

　　6. 同理建立工程：dubboxDemo-web （服务消费者）

           tomcat7

　四。配置dubboxDemo-Service

　　1. dubboxDemo-Service 工程新建接口： UserService

package com.dubboxDemo.service;public interface UserService {    public String getName();}

　　2. 实现这个接口

package com.dubboxDemo.service.impl;import com.alibaba.dubbo.config.annotation.Service;import com.dubboxDemo.service.UserService;@Servicepublic class UserServiceImpl implements UserService {    @Override    public String getName() {        return "我的 dubboDemo";    }}

　　3. 配置applicationContext-service.xml

　　4. 配置web.xml


       
      
       Archetype Created Web Application
        
        
          
       
        contextConfigLocation
           
           
       
        classpath:applicationContext*.xml
         
        
          
       
        org.springframework.web.context.ContextLoaderListener

五。配置dubboxDemo-web

　　1. 把工程dubboxDemo-Service里的接口 UserService 复制下来，包路径要两者一样

　　2. 实现控制器

package com.dubboxDemo.controller;import com.alibaba.dubbo.config.annotation.Reference;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import com.dubboxDemo.service.UserService;@Controller@RequestMapping("/user")public class UserController {    @Reference    private UserService userService;    @RequestMapping("/showName")    @ResponseBody    public String showName(){        return userService.getName();    }}

　　3. 配置applicationContext-web.xml

　　4. 配置web.xml


       
      
       Archetype Created Web Application
        
        
          
       
        CharacterEncodingFilter
             
       
        org.springframework.web.filter.CharacterEncodingFilter
           
             
        
         encoding
              
        
         utf-8
            
           
             
        
         forceEncoding
              
        
         true
            
         
        
        
          
       
        CharacterEncodingFilter
           
       
        /*
         
        
        
        
       
        springmvc
           
       
        org.springframework.web.servlet.DispatcherServlet
         
           
        
         contextConfigLocation
            
            
        
         classpath:applicationContext-web.xml
          
         
        
        
          
       
        springmvc
           
       
        *.do
