Kafka集群环境搭建

• 环境搭建准备

  - 准备zookeeper环境（zookeeper-3.4.6）
  - 下载kafka安装包（kafka_2.12-2.1.0）
  - 上传到服务器
  

• 搭建kafka环境

  # 解压kafka安装包到/usr/local
   tar -zxvf kafka_2.12-2.0.0.tgz -C /usr/local/
  # 重命名kafka
  cd /usr/local/
  mv kafka_2.12-2.0.0/ kafka_2.12
  
  # 修改server.properties
  vi /usr/local/kafka_2.12/conf/
  (1) broker.id=0
  (2)  添加port
  port=9092
  （3） 添加host.name
  host.name=192.168.147.102
   (4)  num.partitions(分区数)
  num.partitions=5
   (5) 日志输出地址  
  log.dirs=/usr/local/kafka_2.12/kafka-logs
   (6) zk集群地址
  zookeeper.connect=192.168.147.102:2181,192.168.147.103:2181,192.168.147.104:2181
  

  • 创建kafka存储消息(log日志数据)

    [root@bigdata01 config]# mkdir -p /usr/local/kafka_2.12/kafka-logs
    [root@bigdata01 config]# cd /usr/local/kafka_2.12/
    [root@bigdata01 kafka_2.12]# ls
    bin  config  kafka-logs  libs  LICENSE  NOTICE  site-docs
    

    • 启动kafka

      /usr/local/kafka_2.12/bin/kafka-server-start.sh /usr/local/kafka_2.12/config/server.properties &
