資料採集的flume架構
測試1:
新建一個flume1.conf檔案
name
a1.sources = r1
a1.channels = c1
a1.sinks = k1
source
a1.sources.r1.type = netcat
a1.sources.r1.bind = DAQ102
a1.sources.r1.port = 6666
channel
a1.channels.c1.type = memory
a1.channels.c1.capacity = 10000
a1.channels.c1.transactionCapacity = 1000
sink
a1.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink
a1.sinks.k1.kafka.topic = atguigu
a1.sinks.k1.kafka.bootstrap.servers = DAQ102:9092
a1.sinks.k1.kafka.producer.acks = 1
a1.sinks.k1.useFlumeEventFormat = false
bind
a1.sources.r1.channels=c1
a1.sinks.k1.channel=c1
測試2:
使用選擇器,將不同的資料新增到不同的topic中
攔截器程式碼:
package com.hybg.daq;
import org.apache.flume.Context;
import org.apache.flume.Event;
import org.apache.flume.interceptor.Interceptor;
import java.nio.charset.StandardCharsets;
import java.util.List;
import java.util.Map;
public class MyInterceptor implements Interceptor {
@Override public void initialize() { } @Override public Event intercept(Event event) { //原理:根據body的資料包含什麼內容在header中新增什麼內容 //獲取header檔案 Map<String, String> headers = event.getHeaders(); //獲取body檔案 String string = new String(event.getBody(), StandardCharsets.UTF_8); //判斷是否包含某個檔案 if(string.contains("atguigu")){ headers.put("topic","atguigu"); }else if(string.contains("shangguigu")){ headers.put("topic","shangguigu"); }else { headers.put("topic","other"); } return event; } @Override public List<Event> intercept(List<Event> list) { for (Event event : list) { intercept(event); } return list; } @Override public void close() { } public static class MyBuilder implements Builder{ @Override public Interceptor build() { return new MyInterceptor(); } @Override public void configure(Context context) { } }
}
name
a1.sources = r1
a1.channels = c1
a1.sinks = k1
source
a1.sources.r1.type = netcat
a1.sources.r1.bind = DAQ102
a1.sources.r1.port = 4444
配置攔截器
a1.sources.r1.interceptors = i1
a1.sources.r1.interceptors.i1.type = com.hybg.daq.MyInterceptor$MyBuilder
channel
a1.channels.c1.type = memory
a1.channels.c1.capacity = 10000
a1.channels.c1.transactionCapacity = 1000
sink
a1.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink
a1.sinks.k1.kafka.topic = other
a1.sinks.k1.kafka.bootstrap.servers = DAQ102:9092,DAQ103:9092,DAQ104:9092
a1.sinks.k1.kafka.producer.acks = 1
a1.sinks.k1.useFlumeEventFormat = false
bind
a1.sources.r1.channels=c1
a1.sinks.k1.channel=c1
測試三:
name
a1.sources = r1
a1.channels = c1
a1.sinks = k1
source
a1.sources.source1.type = org.apache.flume.source.kafka.KafkaSource
a1.sources.source1.batchSize = 5000
a1.sources.source1.batchDurationMillis = 2000
a1.sources.source1.kafka.bootstrap.servers = DAQ102:9092,DAQ103:9092,DAQ104:9092
a1.sources.source1.kafka.topics = atguigu,shangguigu,other
a1.sources.source1.kafka.consumer.group.id = customs
channel
a1.channels.c1.type = memory
a1.channels.c1.capacity = 10000
a1.channels.c1.transactionCapacity = 1000
sinks
a1.sinks.k1.type = logger
bind
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1
①三個元件都有
name
a1.sources = r1
a1.channels = c1
a1.sinks=k1
sources
a1.sources.r1.type = netcat
a1.sources.r1.bind = DAQ102
a1.sources.r1.port = 5555
channel
a1.channels.c1.type = org.apache.flume.channel.kafka.KafkaChannel
a1.channels.c1.kafka.bootstrap.servers = DAQ102:9092,DAQ103:9092,DAQ104:9092
a1.channels.c1.kafka.topic = atguigu
a1.channels.c1.parseAsFlumeEvent = false
sink
a1.sinks.k1.type = logger
bind
a1.sources.r1.channels = c1
a1.sinks.r1.channel = c1
②有source有channel
name
a1.sources = r1
a1.channels = c1
sources
a1.sources.r1.type = netcat
a1.sources.r1.bind = DAQ102
a1.sources.r1.port = 5555
channel
a1.channels.c1.type = org.apache.flume.channel.kafka.KafkaChannel
a1.channels.c1.kafka.bootstrap.servers = DAQ102:9092,DAQ103:9092,DAQ104:9092
a1.channels.c1.kafka.topic = atguigu
a1.channels.c1.parseAsFlumeEvent = false
bind
a1.sources.r1.channels = c1
③有sink有channel
name
a1.channels = c1
a1.sinks=k1
channel
a1.channels.c1.type = org.apache.flume.channel.kafka.KafkaChannel
a1.channels.c1.kafka.bootstrap.servers = DAQ102:9092,DAQ103:9092,DAQ104:9092
a1.channels.c1.kafka.topic = atguigu
a1.channels.c1.parseAsFlumeEvent = false
sink
a1.sinks.k1.type = logger
bind
a1.sinks.r1.channel = c1
資料採集模組:
第一層flume:
name
a1.sources = r1
a1.channels = c1
sources
a1.sources.r1.type = TAILDIR
a1.sources.r1.filegroups = f1
將資料夾中所有的app的檔案都進行讀取
a1.sources.r1.filegroups.f1 = /opt/module/applog/log/app.*
a1.sources.r1.batchSize = 1000
設定斷點續傳的檔案儲存位置
a1.sources.r1.positionFile =/opt/module/flume-1.9.0/position/taildir_position.json
攔截器j
a1.sources.r1.interceptors = i1
a1.sources.r1.interceptors.i1.type = com.hybg.daq.TaildirInterceptor$MyBuilder
channel
a1.channels.c1.type = org.apache.flume.channel.kafka.KafkaChannel
a1.channels.c1.kafka.bootstrap.servers = DAQ102:9092,DAQ103:9092
a1.channels.c1.kafka.topic = topic_log
a1.channels.c1.parseAsFlumeEvent = false
bind
a1.sources.r1.channels = c1
第二層flume:
name
a2.sources = r1
a2.channels = c1
a2.sinks = k1
source
a2.sources.r1.type = org.apache.flume.source.kafka.KafkaSource
a2.sources.r1.batchSize = 1000
a2.sources.r1.batchDurationMillis = 2000
a2.sources.r1.kafka.bootstrap.servers = DAQ102:9092,DAQ103:9092
a2.sources.r1.kafka.topics = topic_log
a2.sources.r1.useFlumeEventFormat = false
攔截器
設定攔截器後可能會導致錯誤,出現timestrap不能讀取的問題
a2.sources.r1.interceptors = i1
a2.sources.r1.interceptors.i1.type = com.hybg.daq.timeInterceptor$MyBuilder
channel
a2.channels.c1.type = file
檔案的
a2.channels.c1.dataDirs = /opt/module/flume-1.9.0/jobs/filechannel
a2.channels.c1.capacity = 1000000
a2.channels.c1.transactionCapacity = 10000
a2.channels.c1.checkpointDir = /opt/module/flume-1.9.0/jobs/checkpointdir
a2.channels.c1.keep-alive = 3
a1.channels.c1.useDualCheckpoints = true
a1.channels.c1. backupCheckpointDir = /otherdiskdir
sinks
a2.sinks.k1.type = hdfs
a2.sinks.k1.hdfs.path = /origin_data/gmall/log/topic_log/%Y-%m-%d
a2.sinks.k1.hdfs.filePrefix = log-
a2.sinks.k1.hdfs.round = false
a2.sinks.k1.hdfs.roundValue = 10
a2.sinks.k1.hdfs.rollSize = 134217728
a2.sinks.k1.hdfs.rollCount = 0
控制輸出檔案是原生檔案。
a2.sinks.k1.hdfs.fileType = CompressedStream
a2.sinks.k1.hdfs.codeC = lzop
bind
a2.sources.r1.channels = c1
a2.sinks.k1.channel = c1
啟動指令碼2:
!/bin/bash
if [ $# -lt 1 ]
then
echo “<<<<<<<<<<<<<<<<<<<<輸入有效引數>>>>>>>>>>>>>>>>>>>>”
echo “{start,stop}”
exit
fi
case $1 in
“start”)
echo “<<<<<<<<<<<<<<<<<<<<向HDFS傳遞資料>>>>>>>>>>>>>>>>>>>>”
ssh DAQ104 “flume-ng agent -c $FLUME_HOME/conf -f $FLUME_HOME/jobs/flume_2.conf -n a2 -Dflume.root.logger=INFO,console 1>/opt/module/flume-1.9.0 2>&1 &”
;;
“stop”)
echo “<<<<<<<<<<<<<<<<<<<<停止向HDFS傳遞資料>>>>>>>>>>>>>>>>>>>>”
ssh DAQ104 “ps -ef | grep flume_2.conf | grep -v grep | awk ‘{print $2}’ | xargs kill -9”
