注意: 
第二步需要将下载的Pandora容器taobao-hsf.tgz放到/data/ilucky/hsf/taobao-tomcat-7.0.59/deploy目录下,
同时解压缩,最终生成taobao-hsf.sar目录。

/data/ilucky/hsf/taobao-tomcat-7.0.59
root@5942:/data/ilucky/hsf/taobao-tomcat-7.0.59# cd deploy/
root@5942:/data/ilucky/hsf/taobao-tomcat-7.0.59/deploy# ls
itemcenter  itemcenter.war  taobao-hsf.sar  taobao-hsf.tgz
root@5942:/data/ilucky/hsf/taobao-tomcat-7.0.59/deploy#

轻量配置中心:

注意: 无论是在需要访问轻量配置中心的机器上,还是consumer & provider所在的机器上都需要配置: 192.168.1.100 jmenv.tbsite.net

如果通过访问http://jmenv.tbsite.net:8080出现如下页面,说明轻量配置中心安装成功。

原始demo 代码内容很简单,如果使用过dubbo,极为类似,一目了然~) 需要注意: carshop下三个项目的角色。

通过查看detail(Consumer服务)代码 ,可以知道这是一个war项目,只包含一个Servlet (测试)和一个Listener。
Listener内容也能很简单: 一个while(true), 即周期性的去访问Provider服务。

package com.alibaba.edas.carshop.detail;

import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;

import org.springframework.context.ApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

import com.alibaba.edas.carshop.itemcenter.ItemService;


/**
 * Alibaba Group EDAS. http://www.aliyun.com/product/edas
 */
public class StartListener implements ServletContextListener{
	
	@Override
	public void contextInitialized( ServletContextEvent sce ) {
		ApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext( sce.getServletContext() );
		final ItemService itemService = ( ItemService ) ctx.getBean( "item" );
		Thread thread = new Thread( new Runnable() {
			@Override
			public void run() {
				while ( true ) {
					try {
						Thread.sleep( 500l );
						System.out.println( itemService.getItemById( 1111 ) );
						System.out.println( itemService.getItemByName( "myname is le" ) );
					} catch ( Throwable e ) {
						e.printStackTrace();
					}
				}
			}
		} );
		thread.start();
	}

	@Override
	public void contextDestroyed( ServletContextEvent sce ) {
		// TODO Auto-generated method stub
	}

}

通过maven将detail打包, 连同上面的taobao-hsf.sar放到${taobao_ali_tomcat_home}/depoly目录下,启动tomcat服务,则Consuemr部署成功。
注意: Consuemr服务器上需要配置hosts: 10.0.1.224 jmenv.tbsite.net(轻量配置中心所在服务器)

接着看itemcenter (Provider) 服务, Provider服务同样是一个war项目,只包含一个Servlet(用来测试)和Hsf服务的实现类,如下:

package com.alibaba.edas.carshop.itemcenter;

import java.util.Random;

/**
 * Alibaba Group EDAS. http://www.aliyun.com/product/edas
 */
public class ItemServiceImpl implements ItemService {

	@Override
	public Item getItemById( long id ) {
		Item car = new Item();
		car.setItemId( 1l );
		car.setItemName( "Mercedes Benz" );
		return car;
	}
	@Override
	public Item getItemByName( String name ) {
		Item car = new Item();
		car.setItemId( 1l );
		car.setItemName( "Mercedes Benz" );
		return car;
	}
}

通过maven将itemcenter打包, 连同上面的taobao-hsf.sar放到${taobao_ali_tomcat_home}/depoly目录下,启动tomcat服务,则Provider部署成功。
注意:Provider服务器上需要配置hosts: 10.0.1.224 jmenv.tbsite.net(轻量配置中心所在服务器)
最后观察轻量配置中心的界面上的服务列表(提供者列表和调用者列表)是否准确。同时结合Consumer和Provider日志,看是否有异常信息。

安装使用时遇到的问题:

  1. 如果启动consumer对应的ali-tomcat服务时,报如下错误,说明没有配置hosts: 10.0.1.224 jmenv.tbsite.net

2. Proivder服务启动后,一直注册不到轻量配置中心,即在服务列表的提供者列表中看不到。
后来发现,没有将taobao-hsf.sar放到${taobao_ali_tomcat_home}/depoly目录下,所以服务启动后没有去注册。这是一个疏忽,正确的启动日志如下:

  1. 解决了上面的问题,轻量配置中的服务列表-提供者列表有了提供者内容,但是Consumer调用Provider服务时报如下错误信息:
HTTP Status 500 - HSFServiceAddressNotFoundException-
type Exception report

message HSFServiceAddressNotFoundException-

description The server encountered an internal error that prevented it from fulfilling this request.

错误的意思是: Consumer不可以消费到正确的Provider服务。参考: https://blog.csdn.net/shengqianfeng/article/details/84373515
检查Provider的详情: 发现Provider对外提供的服务是0.0.23.54,并不是10.0.3.42.

在这里插入图片描述
同时查看Provider日志,发现地址也是错误的:
在这里插入图片描述
如何去修改这个地址呢? 发现官网上的解决办法:
在这里插入图片描述
即在jvm参数中添加-Dhsf.server.ip=10.0.3.42。
再次启动服务,查看提供者详情,发现地址调整过来了。Consumer日志也不报错误了,可以正常调用了。
在这里插入图片描述
注意: 这里还有一个hsf的小bug,即提供者详情改过来了,但是日志打印却没有改过来。
