kafka集群的部署

1.zookeeper集群部署不在简介

zk对外提供2181端口 分别部署在三台机器上面，也是下面的三台

2.hosts文件一定要做 否则kafka系统启动不起来

[root@linux-node1 bin]# cat /etc/hosts192.168.56.11  linux-node1192.168.56.12  linux-node2192.168.56.13  linux-node3

3.linux-node1

kafka文件查看(每个文件的broker.id 不一样 和zk的myid差不多)

分别启动kafka

/root/kafka01/config./kafka-server-start.sh -daemon ../config/server.properties
