springboot 整合kafka 实现生产，消费数据

一 kafka集群的启动

1.1 机器说明

192.168.152.128	master
192.168.152.129	slaver01
192.168.152.130	slaver02

1.2 查看防火墙

如果防火墙开着，则进行关闭：systemctl stop firewalld

1.在master节点查看防火墙状态：systemctl status firewalld

可以看到： Active: inactive (dead) 则表示防火墙已经关闭

[root@localhost ~]# systemctl status firewalld 
Unit firewalld\xc2\xa0.service could not be found.
[root@localhost ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disab
