39-kafka-监控Eagle：

Eagle的安装

1.修改 kafka 启动命令

修改 kafka-server-start.sh 命令中

if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then 
 	export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G" 
fi 

为

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" 

注意：修改之后在启动 Kafka 之前要分发之其他节点

2.上传压缩包 kafka-eagle-bin-1.3.7.tar.gz 到集群/opt/software 目录

3.解压到本地

[root@hadoop102 software]# tar -zvxf kafka-eagle-bin-1.3.7.tar.gz

4.进入刚才解压的目录

[root@hadoop102 software]# cd kafka-eagle-bin-1.3.7/

5.将 kafka-eagle-web-1.3.7-bin.tar.gz 解压至/opt/module

[root@hadoop102 kafka-eagle-bin-1.3.7]# tar -zvxf kafka-eagle-web-1.3.7-bin.tar.gz -C /opt/module/

6.修改名称

[root@hadoop102 module]# mv kafka-eagle-web-1.3.7/ kafka-eagle

7.给启动文件执行权限

[root@hadoop102 module]$ cd bin/

[root@hadoop102 module]$ ll

总用量 12

-rw-r–r–. 1 root root 1848 8 月 22 2017 ke.bat

-rw-r–r–. 1 root root 7190 7 月 30 20:12 ke.sh

[root@hadoop102 module]$ chmod 777 ke.sh

8.修改配置文件

###################################### 
# multi zookeeper&kafka cluster list 
###################################### 
kafka.eagle.zk.cluster.alias=cluster1 
cluster1.zk.list=hadoop102:2181,hadoop103:2181,hadoop104:2181 
###################################### 
# kafka offset storage 
###################################### 
cluster1.kafka.eagle.offset.storage=kafka 
###################################### 
# enable kafka metrics 
##################################### 
kafka.eagle.metrics.charts=true 
kafka.eagle.sql.fix.error=false 
###################################### 
# kafka jdbc driver address 
###################################### 
kafka.eagle.driver=com.mysql.jdbc.Driver 
kafka.eagle.url=jdbc:mysql://hadoop102:3306/ke?useUnicode=true&ch 
aracterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull 
kafka.eagle.username=root 
kafka.eagle.password=000000 

9.添加环境变量

#KAFKA_HOME
export KAFKA_HOME=/opt/module/kafka
export PATH=$PATH:$KAFKA_HOME/bin

#kafka_eagle
export KE_HOME=/opt/module/kafka-eagle
export PATH=$PATH:$KE_HOME/bin

#HADOOP_HOME
export HADOOP_HOME=/opt/module/hadoop-3.1.4
export path=$PATH:$HADOOP_HOME/bin
export path=$PATH:$HADOOP_HOME/sbin

注意：source /etc/profile

10.启动

[root@hadoop102 kafka-eagle]# bin/ke.sh start

注意：启动之前需要先启动 ZK 以及 KAFKA
