一、安装jdk -(版本：1.8.0_191)

1.下载：

https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

解压:tar -zxvf /jdk-8u191-linux-x64.tar.gz -C /home/ppgt/local/

2.修改 /etc/profile 增加：

export JAVA_HOME=/home/ppgt/local/jdk1.8.0_191

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export PATH=$PATH:$JAVA_HOME/bin

3.检测：

java -version

二、安装flume -(版本：1.8.0)

1.下载：

wget http://mirrors.hust.edu.cn/apache/flume/1.8.0/apache-flume-1.8.0-bin.tar.gz

2.解压安装：

tar -zxvf apache-flume-1.8.0-bin.tar.gz -C /home/ppgt/local/

3.验证安装：

bin/flume-ng version

4.修改配置 conf/：

cp flume-env.sh.template flume-env.sh

vi flume-env.sh

//配置java路径：export JAVA_HOME=/usr/local/jdk/jdk1.8.0_191-amd64

5.添加连接kafka的配置文件:conf/flumetokafka.conf

#配置flume链接kafka

# 定义这个agent中各组件的名字

flume_kafka.sources = exec-sources

flume_kafka.sinks = kafka-sink

flume_kafka.channels = memory-channel

# Describe/configure the source

flume_kafka.sources.exec-sources.type = exec

flume_kafka.sources.exec-sources.command = tail -F /home/ppgt/tmpfile/testlogs/data.log

# Describe the sink

flume_kafka.sinks.kafka-sink.type = org.apache.flume.sink.kafka.KafkaSink

flume_kafka.sinks.kafka-sink.topic = topiclogs01

flume_kafka.sinks.kafka-sink.brokerList = localhost:9092

flume_kafka.sinks.kafka-sink.requiredAcks = 1

flume_kafka.sinks.kafka-sink.batchSize = 20

# Use a channel which buffers events in memory

flume_kafka.channels.memory-channel.type = memory

flume_kafka.channels.memory-channel.capacity = 1000

flume_kafka.channels.memory-channel.transactionCapacity = 100

# Bind the source and sink to the channel

flume_kafka.sources.exec-sources.channels = memory-channel

flume_kafka.sinks.kafka-sink.channel = memory-channel

三、安装kafka

1.安装依赖zookeeper -(版本：3.4.12)

1）下载：

wget http://mirror.bit.edu.cn/apache/zookeeper/stable/zookeeper-3.4.12.tar.gz

2）解压：

tar -zxvf zookeeper-3.4.12.tar.gz -C /home/ppgt/local/

3）修改数据存储目录：

conf/zoo.cfg

cp zoo_sample.cfg zoo.cfg

修改值：dataDir=/home/ppgt/kafka_zk_tmp/tmp/zookeeper

2.安装kafka -(版本：0.9.0.0)

1）下载：

wget https://archive.apache.org/dist/kafka/0.9.0.0/kafka_2.11-0.9.0.0.tgz

2）解压：

tar -zxvf kafka_2.11-0.9.0.0.tgz -C /home/ppgt/local/

3）修改配置文件：config/server.properties

a) zookeeper.connect=localhost:2181 #zk服务地址

b) host.name=localhost #主机名

c) log.dirs=/home/ppgt/kafka_zk_tmp/tmp/kafka-logs#kafka数据的存放地址

d) num.partitions=1 #分区数量

e) listeners=PLAINTEXT://:9092 #kafka监听端口

f) broker_id=0 #唯一标识id

四、启动测试步骤

1.启动zookeeper

bin/zkServer.sh start

2.启动flume

bin/flume-ng agent --conf conf --conf-file conf/flumetokafka.conf --name flume_kafka -Dflume.root.logger=INFO,console

3.启动kafka

//启动kafka服务

bin/kafka-server-start.sh /home/ppgt/local/kafka_2.11-0.9.0.0/config/server.properties

//创建一个topic

bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic topiclogs01

//创建一个kafka消费者

php /home/ppgt/www_test_ppgt_admin/syslogs_featrue_v1.0/script/cron/sysLogsConsumerRun.php

bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic topiclogs01 --from-beginning

//或者执行php消费者

//生产测试日志

echo '内容' exce >> /home/ppgt/tmpfile/testlogs/data.log

五、目录说明

1./home/ppgt/local/

conf/zoo.cfg #配置文件

conf/flumetokafka.conf #连接kafka的配置文件

config/server.properties #配置文件

conf/flume-env.sh#配置文件

jdk1.8.0_191 #jdk安装目录

apache-flume-1.8.0-bin/#flume安装目录

kafka_2.11-0.9.0.0/ #kafka安装目录

zookeeper-3.4.12/ #zookeeper安装目录

2./home/ppgt/kafka_zk_tmp/tmp/

zookeeper/ #zookeeper数据存储目录

kafka-logs/ #kafka数据的存放地址
