cp zoo_sample.cfg zoo.cfg 
vim zoo.cfg 
----
# 心跳时间
tickTime=2000
# follow连接leader的初始化连接时间，表示tickTime的倍数
initLimit=10
# syncLimit配置表示leader与follower之间发送消息，请求和应答时间长度。如果followe在设置的时间内不能与leader进行通信，那么此follower将被丢弃，tickTime的倍数
syncLimit=5
# 客户端连接端口
clientPort=2181
# 节点数据存储目录，需要提前创建，注意myid添加，用于标识服务器节点
dataDir=/usr/local/zookeeper/data
dataLogDir=/usr/local/zookeeper/log
server.1=192.168.100.11:2888:3888

4.9 启动 kafka

cd /usr/local/kafka/
# 启动（每个节点）
bin/kafka-server-start.sh config/server.properties >/dev/null 2>&1 &
bin/kafka-server-start.sh -daemon config/server.properties
# 停止（每个节点）
bin/kafka-server-stop.sh config/server.properties

4.10 测试

创建topic。(任意Kafka集群节点)
bin/kafka-topics.sh --zookeeper 192.168.100.11:2181,192.168.100.12:2181,192.168.100.13:2181 --create --topic test --replication-factor 1 --partitions 3

查看topic
bin/kafka-topics.sh --zookeeper 192.168.100.11:2181,192.168.100.12:2181,192.168.100.13:2181 --list

生产者生成数据
bin/kafka-console-producer.sh --broker-list 192.168.100.11:9092,192.168.100.12:9092,192.168.100.13:9092 --topic test

消费者数据：
# --from-beginning 从头开始消费，不加该参数则从最新的消息开始消费，之前的丢弃
# --bootstrap-server 将在kafka集群上创建一个名称为“__consumer_offsets”的topic，50个分区，1个副本，用于存放消费者偏移量
bin/kafka-console-consumer.sh --bootstrap-server 192.168.100.11:9092,192.168.100.12:9092,192.168.100.13:9092 --topic test --from-beginning

bin/kafka-topics.sh --list --zookeeper 192.168.100.11:2181,192.168.100.12:2181,192.168.100.13:2181

bin/kafka-topics.sh --describe --zookeeper 192.168.100.11:2181,192.168.100.12:2181,192.168.100.13:2181 --topic test

删除topic
bin/kafka-topics.sh --delete --zookeeper 192.168.100.11:2181,192.168.100.12:2181,192.168.100.13:2181 --topic test

五： 安装kafka Eagle

wget https://codeload.github.com/smartloli/kafka-eagle-bin/tar.gz/v2.0.2
tar -zxvf v2.0.2 
cd kafka-eagle-bin-2.0.2
tar -zxvf  kafka-eagle-web-2.0.2-bin.tar.gz
mv kafka-eagle-web-2.0.2 /usr/local/eagle

环境变量配置 
vim /etc/profile 
---
export KE_HOME=/usr/local/eagle
export PATH=$KE_HOME/bin:$PATH
----
source /etc/profile 

进入kafka-eagle的conf目录下修改配置文件，配置基础配置
# kafka集群配置
kafka.eagle.zk.cluster.alias=cluster1
cluster1.zk.list=192.168.100.11:2181,192.168.100.12:2181,192.168.100.13:2181
# offset存储配置
cluster1.kafka.eagle.offset.storage=kafka
# 注释或删除以下一行配置
cluster2.kafka.eagle.offset.storage=zk
# 删除topic时需要使用的Token
kafka.eagle.topic.token=polaris
kafka.eagle.metrics.charts=true
kafka.eagle.sql.fix.error=false
kafka.eagle.webui.port=8048
# jdbc配置
kafka.eagle.driver=com.mysql.jdbc.Driver
kafka.eagle.url=jdbc:mysql://192.168.100.11:3306/eagle?createDatabaseIfNotExist=true&amp
kafka.eagle.username=root
kafka.eagle.password=123456

开启Kafka JMX监控
修改Kafka各节点JMX启动配置，开启监控功能：
  cd /usr/local/kafka/bin
  vim kafka-server-start.sh
  ---
  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" 
fi
  ---
  scp kafka-server-start.sh root@192.168.100.12:/usr/local/kafka/bin
  scp kafka-server-start.sh root@192.168.100.13:/usr/local/kafka/bin

验证Kafka Eagle
 cd /usr/local/eagle/bin
 ./eg.sh start
