zookeeper安装部署

• 创建软件安装目录

  mkdir /data/server
  

• 解压安装

  tar -zxvf apache-zookeeper-3.8.3-bin.tar.gz -C /data/server/
  ln -s /data/server/apache-zookeeper-3.8.3-bin/ /data/server/zookeeper
  
  # 创建zookeeper数据存储目录
  mkdir /data/server/zookeeper/zkData
  
  # 创建zookeeper标识文件
  echo '1' > /data/server/zookeeper/zkData/myid
  

• 修改配置

  cp /data/server/zookeeper/zoo_sample.cfg /data/server/zookeeper/zoo.cfg
  

  vim /data/server/zookeeper/zoo.cfg
  # 修改数据存储目录
  dataDir=/data/server/zookeeper/zkData
  # 添加下列集群配置
  server.1=kafka01:2888:3888
  server.2=kafka02:2888:3888
  server.3=kafka03:2888:3888
  

• 分发软件

  # 分发软件至kafka02
  scp -r /data/server/apache-zookeeper-3.8.3-bin/ kafka02:/data/server/
  
  # 分发软件至kafka03
  scp -r /data/server/apache-zookeeper-3.8.3-bin/ kafka03:/data/server/
  

• kafka02与kafka03软链接

  ln -s /data/server/apache-zookeeper-3.8.3-bin/ /data/server/zookeeper
  

• kafka02与kafka03修改myid

  # kafka02修改myid
  echo '2' > /data/server/zookeeper/zkData/myid
  
  # kafka03修改myid
  echo '3' > /data/server/zookeeper/zkData/myid
  

• 防火墙放行端口

  firewall-cmd --zone=public --permanent --add-port={2181,2888,3888}/tcp
  firewall-cmd --reload
  

• 设置开机自启

  vim /etc/systemd/system/zookeeper.service
  
  [Unit]
  Description=zookeeper service
  After=network.target
   
  [Service]
  User=root
  Group=root 
  Type=forking
  Environment="JAVA_HOME=/opt/java/jdk1.8.0_171"
  ExecStart=/data/server/zookeeper/bin/zkServer.sh start
  ExecStop=/data/server/zookeeper/bin/zkServer.sh stop
  PrivateTmp=false
  Restart=always
   
  [Install]
  WantedBy=multi-user.target
  

  systemctl daemon-reload
  systemctl start zookeeper
  systemctl enable zookeeper
  

• zookeeper状态查看

kafka安装部署

• 解压安装

  tar -zxvf kafka_2.13-3.6.0.tgz -C /data/server/
  ln -s /data/server/kafka_2.13-3.6.0/ /data/server/kafka
  

• 修改配置

  vim /data/server/kafka/config/server.properties
  broker.id=0
  # 日志目录
  log.dirs=/data/server/kafka/kafka-logs
  
  # zookeeper连接地址及目录
  zookeeper.connect=kafka01:2181,kafka02:2181,kafka03:2181/kafka
  

• 分发软件

  # 分发软件至kafka02
  scp -r /data/server/kafka_2.13-3.6.0/ kafka02:/data/server/
  
  分发软件至kafka03
  scp -r /data/server/kafka_2.13-3.6.0/ kafka03:/data/server/
  

• kafka02与kafka03软链接

  ln -s /data/server/kafka_2.13-3.6.0/ /data/server/kafka
  

• 修改kafka02和kafka03的broker.id

  vim /data/server/kafka/config/server.properties
  
  # kafka02
  broker.id=1
  
  # kafka03
  broker.id=2
  

• 防火墙放行端口

  firewall-cmd --zone=public --permanent --add-port=9092/tcp
  firewall-cmd --reload
  

• 开机自启

  vim /etc/systemd/system/kafka.service
  

  [Unit]

  PrivateTmp=false
  Restart=always
   
  [Install]
  WantedBy=multi-user.target
  

  systemctl daemon-reload
  systemctl start kafka
  systemctl enable kafka
