MetaQ集群安装测试

1，ZooKeeper集群安装，自己搜索安装

2，下载https://github.com/killme2008/Metamorphosis/tree/metamorphosis-all-1.4.6.2，如果不想自己编译可以直接下载http://fnil.net/downloads/index.html，我这里选择自己编译，主要是以后如果出现问题自己可以修改其源码，重新编译

3，maven编译,maven环境自己搜索配置好，下载all项目后需要编译其子项目metamorphosis-server-wrapper。dos环境进入其目录下mvn eclipse:eclipse，完成后导入到eclipse,用eclipse插件编译。或者直接dos该目录下执行mvn clean install -Dmaven.test.skip=true。完成后target目录下生产其jar包；

可以在工程创建lib文件夹，输入以下命令：mvn dependency:copy-dependencies -DoutputDirectory=lib （不加DoutputDirectory会默认输出到targed/dependency下）。再把install的jar包也copy到lib下。

4，完成编译后上传到服务器

  需要修改conf/server.ini文件

[system]brokerId=2

numPartitions=1

serverPort=8123

ashboardHttpPort=8120

unflushThreshold=0

unflushInterval=10000

maxSegmentSize=1073741824

maxTransferSize=1048576

deletePolicy=delete,168

deleteWhen=0 0 6,18 * * ?

flushTxLogAtCommit=1

stat=true

dataPath=/data1/metaq/data

dataLogPath=/data1/metaq/log

[zookeeper]

zk.zkConnect=192.168.1.1:2181,192.168.1.2:2181,192.168.1.3:2181

zk.zkSessionTimeoutMs=30000

zk.zkConnectionTimeoutMs=30000

zk.zkSyncTimeMs=5000

;; Topics section

[topic=test]

[topic=meta-test]

集群的话需要修改上面标红部分，brokerId保证每个服务器节点上不一样就行

dataPath，dataLogPath如果自己制定，需要每台服务器mkdir

分发到个节点，在每台节点的bin下都执行metaServer.sh start

需要停止时执行metaServer.sh stop

查看状态sh metaServer.sh  status

5，应用例子

package com.test.metaq;

import java.util.concurrent.Executor;

import com.taobao.metamorphosis.Message;
import com.taobao.metamorphosis.client.MessageSessionFactory;
import com.taobao.metamorphosis.client.MetaClientConfig;
import com.taobao.metamorphosis.client.MetaMessageSessionFactory;
import com.taobao.metamorphosis.client.consumer.ConsumerConfig;
import com.taobao.metamorphosis.client.consumer.MessageConsumer;
import com.taobao.metamorphosis.client.consumer.MessageListener;
import com.taobao.metamorphosis.exception.MetaClientException;
import com.taobao.metamorphosis.utils.ZkUtils.ZKConfig;

public class AsyncConsum {

	public static void main(String[] args) {
		final MetaClientConfig metaClientConfig = new MetaClientConfig();  
        final ZKConfig zkConfig = new ZKConfig();  
        zkConfig.zkConnect = "192.168.1.1:2181";  
        metaClientConfig.setZkConfig(zkConfig);  
        MessageSessionFactory sessionFactory = null;
		try {
			sessionFactory = new MetaMessageSessionFactory(metaClientConfig);
		} catch (MetaClientException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}  
        final String topic = "test";  
        final String group = "meta-example";  
        MessageConsumer consumer = sessionFactory.createConsumer(new ConsumerConfig(group));  
       
        try {
			consumer.subscribe(topic, 1024 * 1024, new MessageListener() {  
			    public void recieveMessages(Message message) {  
			        System.out.println("Receive message " + new String(message.getData()));  
			    }  
			    public Executor getExecutor() {  
			        return null;  
			    }  
			});
			consumer.completeSubscribe();
		} catch (MetaClientException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}  
	}

}

package com.test.metaq;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

import com.taobao.metamorphosis.Message;
import com.taobao.metamorphosis.client.MessageSessionFactory;
import com.taobao.metamorphosis.client.MetaClientConfig;
import com.taobao.metamorphosis.client.MetaMessageSessionFactory;
import com.taobao.metamorphosis.client.producer.MessageProducer;
import com.taobao.metamorphosis.client.producer.SendResult;
import com.taobao.metamorphosis.exception.MetaClientException;
import com.taobao.metamorphosis.utils.ZkUtils.ZKConfig;

public class Products {

	public static void main(String[] args) {
		final MetaClientConfig metaClientConfig = new MetaClientConfig();
		final ZKConfig zkConfig = new ZKConfig();
		zkConfig.zkConnect = "192.168.1.1:2181";
		metaClientConfig.setZkConfig(zkConfig);
		
		MessageSessionFactory sessionFactory = null;
		try {
			sessionFactory = new MetaMessageSessionFactory(metaClientConfig);
		} catch (MetaClientException e) {
			e.printStackTrace();
		}
		
		MessageProducer producer = sessionFactory.createProducer();
		final String topic = "test";
		producer.publish(topic);
		BufferedReader reader = new BufferedReader(new InputStreamReader(
				System.in));
		String line = "qiujinyong";
		try {
			while ((line = reader.readLine()) != null) {
				SendResult sendResult = producer.sendMessage(new Message(topic,
						line.getBytes()));
				if (!sendResult.isSuccess()) {
					System.err.println("Send message failed,error message:"
							+ sendResult.getErrorMessage());
				} else {
					System.out.println("Send message successfully,sent to "
							+ sendResult.getPartition());
				}
			}
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (MetaClientException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

	}

}

打包test.jar后，传服务器上 java -cp test.jar com.test.metaq.Products 命令行输入message

打包test.jar后，传服务器上 java -cp test.jar com.test.metaq.AsyncConsum 命令行会接收到message
