Kafka2.8.0集群安装教程

Kafka2.8.0集群安装教程

准备工作

node01~node04(四个节点机器,三台也可以),

kafka安装node01~~node03

启动zookeeper,这里依次启动node131,node132,node133上的zk。(关于zookeeper集群安装请看https://blog.csdn.net/qq_41578037/article/details/123809220)

[root@node131 ~]# zkServer.sh start

查看zookeeper根目录,查看当前目录,此时只有zookeeper一个节点。

[root@node130 ~]# zkCli.sh
[zk: localhost:2181(CONNECTED) 0] ls /
[zookeeper]

kafka安装

1、解压kafka

这里采用的是直接将包下载好上传,也可以使用wget命令。

[root@node130 usr]# tar -zxvf kafka_2.12-2.8.0.tgz

2、添加kafka配置环境

export KAFKA_HOME=/usr/kafka2.8.0/
export PATH=$PATH:$KAFKA_HOME/bin

3、修改kafka配置文件,修改zk地址,log地址等

这里启动3台,130,131,132

[root@node131 data]# cd /usr/kafka2.8.0/config/
修改server.properties
broker.id=131
#listeners=PLAINTEXT://:9092
host.name=192.168.66.131
zookeeper.connect=192.168.66.131:2181,192.168.66.132:2181,192.168.66.133:2181/kafka
log.dirs=/usr/kafka2.8.0/logs/

启动命令

[root@node131 data]#  kafka-server-start.sh /usr/kafka2.8.0/config/server.properties
 INFO KafkaConfig values:
  advertised.host.name = null
        advertised.listeners = null
        advertised.port = null
        alter.config.policy.class.name = null
        alter.log.dirs.replication.quota.window.num = 11
        alter.log.dirs.replication.quota.window.size.seconds = 1
        authorizer.class.name =
        auto.create.topics.enable = true
        auto.leader.rebalance.enable = true
        background.threads = 10
        broker.heartbeat.interval.ms = 2000
        broker.id = 131
        broker.id.generation.enable = true
………………

启动报错:

ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)
kafka.common.InconsistentClusterIdException: The Cluster ID 4S5KkuX2Q9-eWyOXVm1X3A doesn't match stored clusterId Some(3QYVX3qUScC6IXsXIyIR1g) in meta.properties. The broker is trying to join the wrong cluster. Configured zookeeper.connect may be wrong

主要问题就是启动集群中Cluster ID 与现有的不一致,可以删除 meta.properties(启动kafka后自动生成),也可以修改 meta.properties中的Cluster ID 即可。

查看zk节点:

[zk: localhost:2181(CONNECTED) 4] ls /kafka
[cluster, controller_epoch, controller, brokers, feature, admin, isr_change_notification, consumers, log_dir_event_notification, latest_producer_id_block, config]

后续kafka系列会介绍这里节点的作用。

这里用的是kafka-tools,一直next。。。。。Kafka2.8.0集群安装教程_第2张图片

安装完运行:

点击确定,开始配置,注意这里选择kafka版本要和安装的版本一致。
