一、环境准备

• kafka-2.2.1-kafka4.1.0.tar.gz
• 已经安装好zookeeper环境
• kafka-eagle-bin-1.3.9.tar.gz

二、安装部署

• 解压安装包

[hadoop@hadoop000 software]$ tar -zxvf kafka-2.2.1-kafka4.1.0.tar.gz -C ../app/
[hadoop@hadoop000 app]$ ln -s kafka_2.11-2.2.1-kafka-4.1.0 kafka

• 配置环境变量

[hadoop@hadoop000 ~]$ vi ~/.bash_profile 
export KAFKA_HOME=/home/hadoop/app/kafka
export PATH=${KAFKA_HOME}/bin:${PATH}
[hadoop@hadoop000 ~]$source ~/.bash_profile

• 修改kafka配置文件

[hadoop@hadoop000 config]$ vi server.properties 
broker.id=0
host.name=hadoop000
port=9092
advertised.listeners=PLAINTEXT://hadoop000:9092
log.dirs=/home/hadoop/log/kafka-logs
zookeeper.connect=hadoop000:2181/kafka

auto.create.topics.enable=false
unclean.leader.election.enable=false
auto.leader.rebalance.enable=false
delete.topic.enable=true

• 启动与停止

[hadoop@hadoop000 bin]$ vi kafka-server-start.sh 
if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
   # export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
    export KAFKA_HEAP_OPTS="-server -Xms2G -Xmx2G -XX:PermSize=128m -XX:+UseG1GC -XX:MaxGCPauseMillis=200 -XX:ParallelGCThreads=8 -XX:
ConcGCThreads=5 -XX:InitiatingHeapOccupancyPercent=70"
    export JMX_PORT="9999"
fi

#启动
[hadoop@hadoop000 kafka]$ bin/kafka-server-start.sh -daemon config/server.properties 
#停止
[hadoop@hadoop000 kafka]$ bin/kafka-server-stop.sh
#如果出现   No kafka server to stop
[hadoop@hadoop000 kafka]$ vi bin/kafka-server-stop.sh 
#PIDS=$(ps ax | grep -i 'kafka\.Kafka' | grep java | grep -v grep | awk '{print $1}')
PIDS=$(ps ax | grep -i 'kafka\.wrap\.Kafka' | grep java | grep -v grep | awk '{print $1}')

三、kafka基本操作

TODO......

四、安装kafka-eagle

• 解压安装包

[hadoop@hadoop000 software]$ tar -zxvf kafka-eagle-bin-1.3.9.tar.gz -C ../app/
[hadoop@hadoop000 kafka-eagle-bin-1.3.9]$ tar -zxvf kafka-eagle-web-1.3.9-bin.tar.gz 
[hadoop@hadoop000 kafka-eagle-web-1.3.9]$ ln -s /home/hadoop/app/kafka-eagle-bin-1.3.9/kafka-eagle-web-1.3.9 /home/hadoop/app/kafka-eagle

• 配置system-config.properties

[hadoop@hadoop000 conf]$ vi system-config.properties

• 启动Kafka Eagle

[hadoop@hadoop000 kafka-eagle]$ vi ~/.bash_profile
export KE_HOME=/home/hadoop/app/kafka-eagle
export PATH=${KE_HOME}/bin:${PATH}
[hadoop@hadoop000 kafka-eagle]$ source ~/.bash_profile
[hadoop@hadoop000 bin]$ chmod +x ke.sh 

在ke.sh脚本中，支持以下命令：
Usage: ke.sh {start|stop|restart|status|stats|find|gc|jdk}

命令	说明
ke.sh start	启动Kafka Eagle系统
ke.sh stop	停止Kafka Eagle系统
ke.sh restart	重启Kafka Eagle系统
ke.sh status	查看Kafka Eagle系统运行状态
ke.sh stats	统计Kafka Eagle系统占用Linux资源情况
ke.sh find [ClassName]	查看Kafka Eagle系统中的类是否存在

• 特别注意
  如果启动发现，打开页面是500，且查看日志为:

Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.fasterxml.jackson.annotation.JsonInclude$Value

需要重新编译源码，修改源码 kafka-eagle-web/pom.xml，把 jackson.version 版本由 2.9.6 改为 2.4.5，重新编译一下即可。

<properties>
   ...
   <jackson.version>2.9.6</jackson.version>
</properties>
<properties>
   ...
   <jackson.version>2.4.5</jackson.version>
