Kafka集群安装

1. 下载安装包  kafka_2.11-1.0.0.tgz
2.  tar -xvf  kafka_2.11-1.0.0.tgz
3.  创建kafka日志目录
    mkdir /software/kafka_2.11-1.0.0/logs
4.  修改conf/server.properties配置文件  关键点
   broker.id=0
   log.dirs=/software/kafka_2.11-1.0.0/logs
   zookeeper.connect=master:2181,slave1:2181,slave2:2181
5.  同步到slave1，slave2
   scp -r /software/kafka_2.11-1.0.0/ root@slave1:/software/
   scp -r /software/kafka_2.11-1.0.0/ root@slave2:/software/
6.  修改slave1，slave2中conf/server.properties中broker.id
   值分别为1 ，2 
7. 将Kafka相关配置进系统环境  /ec/profile   ~/.bash_profile
      export JAVA_HOME=/software/jdk1.8.0_161
      export ZK_HOME=/software/zookeeper-3.4.10
      export KAFKA_HOME=/software/kafka_2.11-1.0.0
      export PATH=$PATH:$ROCKETMQ_HOME/bin:$JAVA_HOME/bin:$ZK_HOME/bin:$KAFKA_HOME/bin
   source /ec/profile   
   source ~/.bash_profile
8. 创建集群启动脚本
   vim $KAFKA_HOME/bin/kafka-clu-start.sh
      #!/bin/bash
      echo "-----------------------启动kafka集群---------------------"
      echo "-----------------------启动master---kafka---------------------"
      sh $KAFKA_HOME/bin/kafka-server-start.sh -daemon $KAFKA_HOME/config/server.properties >$KAFKA_HOME/logs/server.log 2>&1 &
      sleep 5s;
      echo "-----------------------启动slave1--kafka---------------------"
      ssh slave1 sh $KAFKA_HOME/bin/kafka-server-start.sh -daemon $KAFKA_HOME/config/server.properties >$KAFKA_HOME/logs/server.log 2>&1 &
      sleep 5s;
      echo "-----------------------启动slave2-kafka---------------------"
      ssh slave2 sh $KAFKA_HOME/bin/kafka-server-start.sh -daemon $KAFKA_HOME/config/server.properties >$KAFKA_HOME/logs/server.log 2>&1 &
   chmod  777 $KAFKA_HOME/bin/kafka-clu-start.sh
