配置环境变量（ROCKETMQ_HOME）

修改runserver.cmd

1、进入bin目录下找到runserver.cmd文件，用编辑器打开，因为RocketMQ默认需要2g运行内存，做为测试用，就只要最低配置就好了，注释原有的NameServer 的配置，在其前面加上rem 注释掉，

rem set "JAVA_OPT=%JAVA_OPT% -server -Xms2g -Xmx2g -Xmn1g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

在后面加上

set "JAVA_OPT=%JAVA_OPT% -server -Xms256m -Xmx512m"

2、双击 mqnamesrv.cmd 文件 NameServer 的默认端口是9876

3、配置broker排位置文件

a.用编辑器打开runbroker.cmd文件

注释默认配置，在其前面加上

rem set "JAVA_OPT=%JAVA_OPT% -server -Xms2g -Xmx2g -Xmn1g"

并在后面配置

set "JAVA_OPT=%JAVA_OPT% -server -Xms256m -Xmx512m"

b.配置NameServer地址

rem 指定NameServer的地址

set "NAMESRV_ADDR=localhost:9876"

rem 添加NameServer的地址

call "%ROCKETMQ_HOME%\bin\runbroker.cmd" org.apache.rocketmq.broker.BrokerStartup %*

查看是否有集群注册

.\mqadmin.cmd clusterList -n localhost:9876

修改 conf 文件夹中的 broker.conf 文件
