MetaQ集群安装测试

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 = "10.168.140.48:2181"; 
        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 = "10.168.140.48:2181";
  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
