没有提示，所有机器都执行

在kafka集群中引入zookeeper，主要是为了管理kafka集群的broker。负责管理集群的元数据信息，确保 Kafka 集群的高可用性、高性能和高可靠性。

一、实例配置

IP	用途
192.168.0.217	kafka、zk
192.168.0.218	kafka、zk
192.168.0.219	kafka、zk

二 、zookeeper集群安装

1. 解压zk安装包

   tar xf apache-zookeeper-3.6.2-bin.tar.gz mv apache-zookeeper-3.6.2-bin /data/zookeeper

2. 修改zookeeper配置文件

   $ vim /data/zookeeper/conf/zoo.cfg
   tickTime=2000
   initLimit=10
   syncLimit=5
   dataDir=/data/zookeeper/data
   clientPort=2181
   maxClientCnxns=512
   server.217=192.168.0.217:2888:3888
   server.218=192.168.0.218:2888:3888
   server.219=192.168.0.219:2888:3888

   mkdir /data/zookeeper/data #根据实例自行修改 echo 217 > /data/zookeeper/data/myid

3. 托管到systemd

   $ vim /usr/lib/systemd/system/zookeeper.service
   [Unit]
   Description=Apache Zookeeper service
   Requires=network.target
   After=network.target

   [Service]
   Type=forking
   Environment=JAVA_HOME=/usr/local/java
   ExecStart=/data/zookeeper/bin/zkServer.sh start
   ExecStop=/data/zookeeper/bin/zkServer.sh stop
   Restart=on-failure
   RestartSec=10s

   [Install]
   WantedBy=multi-user.target

   $ systemctl daemon-reload

4. 启动zk

   $ systemctl start zookeeper

三、kafka集群安装

1. 解压kafka安装包

   tar xf kafka_2.12-2.6.0.tgz mv kafka_2.12-2.6.0 /data/kafka

2. 修改kafka配置

   $ vim /data/kafka/config/server.properties

   每个实例不同

   broker.id=217
   listeners=PLAINTEXT://192.168.0.217:9092 #
   advertised.listeners=PLAINTEXT://192.168.0.217:9092 #

   kafka存储日志文件的目录

   log.dirs=/data/kafka/kafka-logs

   存储消费者偏移量的主题的副本因子

   offsets.topic.replication.factor=3

   设置事务日志主题的副本因子

   transaction.state.log.replication.factor=3
   log.retention.hours=48 # 数据保留48小时
   zookeeper.connect=192.168.0.217:2181,192.168.0.218:2181,192.168.0.219:2181 #

   $ mkdir /data/kafka/kafka-logs

3. 托管到systemd

   $ vim /usr/lib/systemd/system/kafka.service
   [Unit]
   Description=Apache Kafka server
   Documentation=http://kafka.apache.org/documentation.html
   Requires=network.target remote-fs.target
   After=network.target remote-fs.target zookeeper.service

   [Service]
   Type=forking
   Environment=JAVA_HOME=/usr/local/java
   ExecStart=/data/kafka/bin/kafka-server-start.sh -daemon /data/kafka/config/server.properties
   ExecStop=/data/kafka/bin/kafka-server-stop.sh /data/kafka/config/server.properties
   Restart=on-failure
   RestartSec=10s

   [Install]
   WantedBy=multi-user.target

   $ systemctl daemon-reload

4. 启动kafka

   $ systemctl start kafka

四、验证

1. 登录zookeeper查看kafka信息

   /data/zookeeper/bin/zkCli.sh

   ls /brokers/ids
   [217, 218, 219]
   get /brokers/ids/217

可以看到kafka已经注册到zookeeper
