Kafka安装

一、安装JDK环境

二、同步时钟

• yum install ntp -y
• ntpdate ntp1.aliyun.com
• clock -w

三、安装zookeeper

• 解析安装包
• 从样例配置拷贝配置 cp conf/zoo_sample.cfg conf/zoo.cfg
  • 修改dataDir数据存放路径（myid文件也存放在改路径下）
  • 常见myid文件，在zoo.cfg增加集群几点信息，server.1=zk01:2888:3888

四、安装kafka

• tar -zxf kafka_2.12-3.2.3.tgz

• vim config/server.properties

  ############################# Server Basics #############################
  
  # The id of the broker. This must be set to a unique integer for each broker.
  broker.id=0
  
  ############################# Socket Server Settings #############################
  
  # The address the socket server listens on. If not configured, the host name will be equal to the value of
  # java.net.InetAddress.getCanonicalHostName(), with PLAINTEXT listener name, and port 9092.
  #   FORMAT:
  #     listeners = listener_name://host_name:port
  #   EXAMPLE:
  #     listeners = PLAINTEXT://your.host.name:9092
  listeners=PLAINTEXT://kafka01:9092
  
  ############################# Log Basics #############################
  
  # A comma separated list of directories under which to store log files
  log.dirs=/usr/local/kafka_2.12-3.2.3/kafka-logs
  
  
  ############################# Zookeeper #############################
  
  # Zookeeper connection string (see zookeeper docs for details).
  # This is a comma separated host:port pairs, each corresponding to a zk
  # server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002".
  # You can also append an optional chroot string to the urls to specify the
  # root directory for all kafka znodes.
  zookeeper.connect=zk01:2181,zk02:2181,zk03:2181

• 远程拷贝kafka安装文件到其他两台主机

  • scp -r ./kafka_2.12-3.2.3/ root@kafka02:/usr/local/，修改config/server.properties文件
    • broker.id=1
    • listeners=PLAINTEXT://kafka02:9092
  • scp -r ./kafka_2.12-3.2.3/ root@kafka03:/usr/local/，修改config/server.properties文件
    • broker.id=2
    • listeners=PLAINTEXT://kafka03:9092

• 启动：./kafka-server-start.sh -daemon ../config/server.properties
