4. 启动

#RocketMQ默认预设的JVM内存是4G。通常虚拟机不够4G内存，需要调整JVM内存大小
vim /app/rocketmq/rocketmq-4.8.0/bin/runserver.sh
#修改：JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m

#1.启动NameServer：提供轻量级的Broker注册中心
nohup bin/mqnamesrv &

#查看日志如下，表示启动成功
less /app/rocketmq/rocketmq-4.8.0/bin/nohup.out
java HotSpot(TM) 64-Bit Server VM warning: Using the DefNew young collector with the CMS collector is deprecated and will likely be removed in a future release
Java HotSpot(TM) 64-Bit Server VM warning: UseCMSCompactAtFullCollection is deprecated and will likely be removed in a future release.
The Name Server boot success. serializeType=JSON

vim /app/rocketmq/rocketmq-4.8.0/bin/runbroker.sh
#修改：JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m"

#为了启动后测试验证，配置开启自动创建Topic
vim /app/rocketmq/rocketmq-4.8.0/conf/broker.conf
#最下面一行添加：autoCreateTopicEnable = true

#2.启动Broker：实际处理消息存储、转发等服务的核心组件
#需要先关闭防火墙
nohup /app/rocketmq/rocketmq-4.8.0/bin/mqbroker &

#检查日志
less /app/rocketmq/rocketmq-4.8.0/bin/nohup.out
