04 flink 集群搭建

前言

 

呵呵 最近有一系列环境搭建的相关需求

记录一下

flink 三个节点 : 192.168.110.150, 192.168.110.151, 192.168.110.152

150 为 master, 151 为 slave01, 152 为 slave02

三台机器都做了 trusted shell  
 

flink 集群搭建

flink 三个节点 : 192.168.110.150, 192.168.110.151, 192.168.110.152

1. 基础环境准备

192.168.110.150, 192.168.110.151, 192.168.110.152 上面安装 jdk, 上传 flink 的安装包

安装包来自于 Apache Downloads

2. flink 配置调整

更新 master, slave01, slave02 的 flink-conf.yml 的配置文件如下

jobmanager.rpc.address: master
jobmanager.rpc.port: 612
jobmanager.bind-host: 0.0.0.0
jobmanager.memory.process.size: 1600
jobmanager.execution.failover-strategy: region

taskmanager.bind-host: 0.0.0.0
taskmanager.host: master
taskmanager.memory.process.size: 1728m
taskmanager.numberOfTaskSlots: 
parallelism.default: 1

rest.port: 8081
rest.address: master
rest.bind-address: 0.0.0.0

jobmanager.rpc.address: master
jobmanager.rpc.port: 612
jobmanager.bind-host: 0.0.0.0
jobmanager.memory.process.size: 1600
jobmanager.execution.failover-strategy: region

taskmanager.bind-host: 0.0.0.0
taskmanager.host: slave01
taskmanager.memory.process.size: 1728m
taskmanager.numberOfTaskSlots: 
parallelism.default: 1

rest.port: 8081
rest.address: master
rest.bind-address: 0.0.0.0

jobmanager.rpc.address: master
jobmanager.rpc.port: 612
jobmanager.bind-host: 0.0.0.0
jobmanager.memory.process.size: 1600
jobmanager.execution.failover-strategy: region

taskmanager.bind-host: 0.0.0.0
taskmanager.host: slave02
taskmanager.memory.process.size: 1728m
taskmanager.numberOfTaskSlots: 
parallelism.default: 1

rest.port: 8081
rest.address: master
rest.bind-address: 0.0.0.0

3. 启动集群 

三台机器 master 启动 jobmanager, slave01, slave02 启动 taskmanager 

相关脚本 存在于 flink 家目录的 bin 目录下面

测试集群

测试的 flink driver program 如下, 然后直接打包 

package com.hx.test;

import org.apache.flink.api.common.functions.MapFunction;

public class Test03SteamingWordCount {

  public static void main(String[] args) throws Exception {

    // 创建一个批处理的执行环境
    StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();

//    Configuration conf = new Configuration();
//    conf.setString(JobManagerOptions.ADDRESS, "192.168.110.150");
//    conf.setInteger(JobManagerOptions.PORT, 6123);
//    conf.setInteger(RestOptions.PORT, 8081);
//    conf.setString(DeploymentOptions.TARGET.key(), RemoteExecutor.NAME);
//    StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment(conf);
    env.setParallelism(1);

    DataStreamSource<String> inputDs = env.addSource(new MySource());
    inputDs
      .flatMap(new FlatMapFunction<String, String>() {
        @Override
        public void flatMap(String s, Collector<String> collector) throws Exception {
          String[] splited = s.split("\\s+");
          for(String str : splited) {
            collector.collect(str);
          }
        }
      })
      .map(new MapFunction<String, Tuple2<String, Integer>>() {
        @Override
        public Tuple2<String, Integer> map(String s) throws Exception {
          return new Tuple2<>(s, 1);
        }
      })
      .keyBy(new KeySelector<Tuple2<String, Integer>, String>() {

        @Override
        public String getKey(Tuple2<String, Integer> stringIntegerTuple2) throws Exception {
          return stringIntegerTuple2.f0;
        }
      })
      .sum(1)
      .addSink(new MySink());


    env.execute();

  }

}

// MySensorSource
class MySource implements SourceFunction<String> {

  private boolean running = true;

  public void cancel() {
    running = false;
  }

  public void run(SourceFunction.SourceContext<String> sourceContext) {
    while (running) {
      sourceContext.collect("234 345 123 346 234");
      sourceContext.collect("123 124");

      try {
        Thread.sleep(5000);
      } catch (Exception e) {
        e.printStackTrace();
      }
    }
  }
}

// MySensorSource
class MySink implements SinkFunction<Tuple2<String, Integer>> {

  private boolean running = true;

  public void invoke(Tuple2<String, Integer> value, SinkFunction.Context context) {
    System.out.println(value.f0 + " - " + value.f1);
  }

}

通过 flink webui 上传 driver program, 然后 可以直接 submitJob 

提交 job 之后, job 的监控如下 

driver program 的标准输出如下
