1：下载地址：

[https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/][https_mirrors.tuna.tsinghua.edu.cn_apache_zookeeper]

下载3.4.14，

不要下3.5.5,  3.5.5是损坏的，里面没有jar包，

启动会报 找不到或无法加载主类 org.apache.zookeeper.server.quorum.QuorumPeerMain

2：上传至liunx目录，随便创建一个文件夹：  解压 ：

tar -zxvf zookeeper-3.4.14.tar.gz

3：进入conf目录：

cd /zookeeper-3.4.14/conf

执行：

cp zoo_sample.cfg zoo.cfg

4：配置一下 zoo.cfg

vim zoo.cfg

加入：

dataLogDir=/tmp/zookeeper/logs

5：启动：进入bin目录

cd  zookeeper-3.4.14/bin

6：执行：

./zkServer.sh start

7：查看是否启动成功：started 代表启动成功

jps查看： 7252就是zookeeper

8:开放防火墙端口

firewall-cmd --zone=public --add-port=2181/tcp --permanent
    
    firewall-cmd --reload

dubbo application配置： [https://github.com/JeffLi1993/springboot-learning-example][https_github.com_JeffLi1993_springboot-learning-example]

创建springboot项目： 提供方

![20190621153234523.png][]

facade-mx ：接口层，定义接口与entity

public interface SocketIoInitService{

service-mx: 接口实现层；  @Service注解为 dubbo包下的

@Component
    @Service(version = "socketIoInitService")
    public class SocketIoInitServiceImpl implements SocketIoInitService {

service-mx：pom.xml引入：

<dependency>
    			<groupId>com.alibaba.boot</groupId>
    			<artifactId>dubbo-spring-boot-starter</artifactId>
    			<version>0.2.0</version>
    		</dependency>
    
    		<dependency>
    			<groupId>org.apache.zookeeper</groupId>
    			<artifactId>zookeeper</artifactId>
    			<version>3.4.13</version>
    		</dependency>

application.yml添加：zookeeper 地址为安装的zookeeper地址

server:
      port: 8086
    
    
    spring:
      application:
        name: socket
       
       
    dubbo:
      application:
        name: socket
      registry:
    # zookeeper 注册中心地址 
        address: zookeeper://192.168.xx.xx:2181
      protocol:
        name: dubbo
    # dubbo端口
        port: 28086

创建springboot项目： 消费方：

pom引入依赖：

<dependency>
    			<groupId>com.alibaba.boot</groupId>
    			<artifactId>dubbo-spring-boot-starter</artifactId>
    			<version>0.2.0</version>
    		</dependency>
    
    		<dependency>
    			<groupId>org.apache.zookeeper</groupId>
    			<artifactId>zookeeper</artifactId>
    			<version>3.4.13</version>
    		</dependency>

application.yml 添加：

server:
      port: 8083
    
       
    spring:
      application:
        name: service-ctisj
    
    
    dubbo:
      application:
        name: service-ctisj
      registry:
    # zookeeper 注册中心地址 
        address: zookeeper://192.168.xx.xx:2181
      protocol:
        name: dubbo
    # dubbo端口
        port: 28086

controller中引入提供方的service；  @Reference 注解为 dubbo包下的。

@RestController
    public class LoginController {
    private static final Logger logger = LoggerFactory.getLogger(LoginController.class);
    	
    	@Autowired
    	private UserUtils userUtils;
    	
    	 @Reference(version = "socketIOUserService")
    	 private SocketIOUserService socketIOUserService;

注意：  必须先启动提供方； 因为参数没设置，  提供方不先启动就会找不到    提供者为null

dubbo-admin：
