Kafka-Eagle框架可以监控Kafka集群的整体运行情况,在生产环境中经常使用。
1、MySQL环境准备
Kafka-Eagle的安装依赖于MySQL,MySQL主要用来存储可视化展示的数据。如果集群中之前安装过MySQL可以跨过该步。
2、Kafka环境准备
1)关闭Kafka集群
[duo@hadoop01 kafka]$ kf.sh stop
2)修改/opt/data/kafka/bin/kafka-server-start.sh命令中
[duo@hadoop01 kafka]$ vim bin/kafka-server-start.sh
修改如下参数值:
if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
fi
if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
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"
#export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
fi
注意:修改之后在启动Kafka之前要分发之其他节点
[duo@hadoop01 bin]$ xsync kafka-server-start.sh
3、Kafka-Eagle安装
官网:https://www.kafka-eagle.org/
(1)上传压缩包kafka-eagle-bin-2.0.8.tar.gz到集群
(2)解压到本地
[duo@hadoop01 software]$ tar -zxvf kafka-eagle-bin-2.0.8.tar.gz
(3)将efak-web-2.0.8-bin.tar.gz解压至/opt/data
[duo@hadoop01 kafka-eagle-bin-2.0.8]$ tar -zxvf efak-web-2.0.8-bin.tar.gz -C /opt/data/
(4)修改配置文件 system-config.properties
[duo@hadoop01 conf]$ vim system-config.properties
######################################
# multi zookeeper & kafka cluster list
# Settings prefixed with 'kafka.eagle.' will be deprecated, use 'efak.' instead
######################################
efak.zk.cluster.alias=cluster1
cluster1.zk.list=hadoop01:2181,hadoop02:2181,hadoop03:2181/kafka
# EFAK webui port
######################################
efak.webui.port=8048
# 配置mysql连接
efak.driver=com.mysql.jdbc.Driver
efak.url=jdbc:mysql://hadoop01:3306/ke?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
efak.username=root
efak.password=000000
(5)添加环境变量
# kafkaEFAK
export KE_HOME=/opt/data/efak-web-2.0.8
export PATH=$PATH:$KE_HOME/bin
注意:source /etc/profile
[duo@hadoop01 conf]$ source /etc/profile
(6)启动
注意:启动之前需要先启动ZK以及KAFKA。
启动efak
[duo@hadoop01 efak]$ bin/ke.sh start
