Dubbo 快速入门

# Dubbo 快速入门

# Zookeeper安装

Dubbo官方推荐使用Zookeeper作为注册中心

# 下载安装

ZooKeeper服务器是用Java创建的，它运行在JVM之上。需要安装JDK 7或更高版本。

Zookeeper下载地址 (opens new window)
将下载的ZooKeeper放到/opt/ZooKeeper目录下

mkdir /opt/ZooKeeper

使用XFTP工具将压缩包传输到Linux系统

将tar包解压到/opt/zookeeper目录下

mkdir /opt/zookeeper
tar -zxvf apache-zookeeper-3.5.6-bin.tar.gz -C /opt/zookeeper

# 配置启动

# 配置zoo.cfg

进入到conf目录拷贝一个zoo_sample.cfg并完成配置

cd /opt/zookeeper/apache-zookeeper-3.5.6-bin/conf && ls
#拷贝
cp  zoo_sample.cfg  zoo.cfg

mkdir /opt/zookeeper/zkdada

修改zoo.cfg

#修改zoo.cfg
vim /opt/zookeeper/apache-zooKeeper-3.5.6-bin/conf/zoo.cfg

修改存储目录：dataDir=/opt/zookeeper/zkdata

# 启动ZooKeeper

cd /opt/zookeeper/apache-zooKeeper-3.5.6-bin/bin/
#启动
 ./zkServer.sh  start

[root@master bin]# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/apache-zookeeper-3.5.6-bin/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

STARTED表示zk启动成功

# 查看ZooKeeper状态

./zkServer.sh status

[root@master bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/apache-zookeeper-3.5.6-bin/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.

zookeeper启动成功。standalone代表zk没有搭建集群，现在是单节点

[root@master bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/apache-zookeeper-3.5.6-bin/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Error contacting service. It is probably not running.

(not running),zookeeper没有启动

关闭ZooKeeper

./zkServer.sh stop

# 测试

因为dubbo-service被dubbo-web所依赖，我们需要先installdubbo-service这个项目。
启动dubbo-web
结果

目前此项目，仍然是单体项目

# Dubbo 引入

# 服务提供者

在dubbo-service的pom.xml文件中引入tomcat插件，并修改打包方式为war

# 修改UserServiceImpl.java

package com.frx01.service.impl;

import com.frx01.service.UserService;
import org.apache.dubbo.config.annotation.Service;

@Service//将这这类提供的方法(服务)对外发布，将访问的地址,ip,端口,路径注册到注册中心中
public class UserServiceImpl implements UserService {
