1. JDK-1.8
2. zookeeper-3.4.14
3. rocketmq-3.2.6

zookeeper

进入到zookeeper的conf目录

清空配置文件，只保留下面这一行。zookeeper关闭日志输出相对简单。

log4j.rootLogger=OFF

rocketmq

进入到rocketmq的conf目录

修改rocketmq JVM 内存大小

进入到rocketmq的bin目录

mqadmin.xml、mqbroker.xml、mqfiltersrv.xml、mqnamesrv.xml

修改options为以下内容，注意Xmx的值一定要比MaxNewSize的值大
MaxNewSize is equal to or greater than the entire heap

	<options>
		<-Xms512m></-Xms512m>
		<-Xmx512m></-Xmx512m>
		<-XX:NewSize>256M</-XX:NewSize>
		<-XX:MaxNewSize>256M</-XX:MaxNewSize>
	</options>

rocketmq数据存储位置为用户目录下的store（如果报错了，开发或者测试环境可以随便删除）

rocketmq日志文件存储位置为用户目录下的logs

rocketmq_client.log日志无法关闭
