rocketmq 4.2.0集群配置

采用的是2m-2s-async模式

1.  修改每台机器的/etc/hosts  文件，增加如下内容

192.168.1.100 nameserver1
192.168.1.102 nameserver2
192.168.1.103 nameserver3
192.168.1.104 nameserver4
192.168.1.100 master1
192.168.1.101 master2
192.168.1.102 slave1
192.168.1.103 slave2

2. 下载bin压缩包： http://mirrors.tuna.tsinghua.edu.cn/apache/rocketmq/4.2.0/rocketmq-all-4.2.0-bin-release.zip

然后解压到某个目录, 比如： /data/rocketmq-4.2.0/
