MetaQ集群安裝測試

1，ZooKeeper集群安裝，可以參考 ZooKeeper集群環境搭建實踐 http://www.linuxidc.com/Linux/2013-04/83562.htm

2，下載https://github.com/killme2008/Metamorphosis/tree/metamorphosis-all-1.4.6.2，如果不想自己編譯可以直接下載http://fnil.net/downloads/index.html，我這裏選擇自己編譯，主要是以後如果出現問題自己可以修改其源碼，重新編譯

3，maven編譯,maven環境自己搜索配置好，下載all項目後需要編譯其子項目metamorphosis-server-wrapper。dos環境進入其目錄下mvn eclipse:eclipse，完成後導入到eclipse,用eclipse插件編譯。或者直接dos該目錄下執行mvn clean install -Dmaven.test.skip=true。完成後target目錄下生產其jar包；

可以在工程創建lib文件夾，輸入以下命令：mvn dependency:copy-dependencies -DoutputDirectory=lib （不加DoutputDirectory會默認輸出到targed/dependency下）。再把install的jar包也copy到lib下。

4，完成編譯後上傳到服務器

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]

集群的話需要修改上面標紅部分，brokerId保證每個服務器節點上不一樣就行

dataPath，dataLogPath如果自己制定，需要每臺服務器mkdir

分發到個節點，在每臺節點的bin下都執行metaServer.sh start

需要停止時執行metaServer.sh stop

查看狀態sh metaServer.sh status

5，應用例子

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後，傳服務器上 java -cp test.jar com.test.metaq.Products 命令行輸入message

打包test.jar後，傳服務器上 java -cp test.jar com.test.metaq.AsyncConsum 命令行會接收到message
