rocky8.6与ubuntu2004一键安装kafka集群

kafka

#注意:生产中zookeeper和kafka一般是分开独立部署的,kafka安装前需要安装java环境

kafka配置文件说明

#消息者先生产消息，消费都后续才启动，也能收到之前生产的消息
#同一个消息在同一个group内的消费者只有被一个消费者消费，比如：共100条消息，在一个group内有A，B两个消费者，其中A消费50条，B消费另外的50条消息。从而实现负载均衡，不同group内的消费者则可以同时消费同一个消息

zookeeper配置文件说明

#默认配置可不做修改
[root@ubuntu1804 ~]#grep -v "#" /usr/local/zookeeper/conf/zoo.cfg
tickTime=2000 #"滴答时间"，用于配置Zookeeper中最小的时间单元长度，单位毫秒，是其它时间配置
的基础
initLimit=10 #初始化时间，包含启动和数据同步，其值是tickTime的倍数
syncLimit=5 #正常工作，心跳监测的时间间隔，其值是tickTime的倍数
dataDir=/tmp/zookeeper #配置Zookeeper服务存储数据的目录,基于安全,可以修改为
dataDir=/usr/local/zookeeper/data
#dataLogdir=/usr/local/zookeeper/logs #可以指定日志路径
clientPort=2181 #配置当前Zookeeper服务对外暴露的端口，用户客户端和服务端建立连接会话
autopurge.snapRetainCount=3 #3.4.0中的新增功能：启用后，ZooKeeper 自动清除功能,会将只保
留此最新3个快照和相应的事务日志,并分别保留在dataDir 和dataLogDir中，删除其余部分，默认值为3,
最小值为3
autopurge.purgeInterval=24 #3.4.0及之后版本，ZK提供了自动清理日志和快照文件的功能，这个参
数指定了清理频率，单位是小时，需要配置一个1或更大的整数，默认是 0，表示不开启自动清理功能
