消息队列的应用场景：主要用于处理高并发作削峰处理、业务解耦等，比如说 大规模的短信推送、订单抓取、库存同步、消息同步等。
wget https://archive.apache.org/dist/rocketmq/4.5.1/rocketmq-all-4.5.1-bin-release.zip
unzip rocketmq-all-4.5.1-bin-release.zip
cd rocketmq-all-4.5.1-bin-release/bin
nohup sh mqnamesrv &
tail -f ~/logs/rocketmqlogs/namesrv.log
# 如果成功启动，能看到类似如下的日志：
2019-07-18 17:03:56 INFO main - The Name Server boot success. ...
nohup sh mqbroker -n localhost:9876 autoCreateTopicEnable=true &
tail -f ~/logs/rocketmqlogs/broker.log
# 如果启动成功，能看到类似如下的日志：
2019-07-18 17:08:41 INFO main - The broker[itmuchcomdeMacBook-Pro.local, 192.168.43.197:10911] boot success. serializeType=JSON and name server is localhost:9876
sh mqshutdown namesrv
如果一直报错 172.17.0.11:10911 连接失败，需要新增ip配置文件并指定
brokerIP1=xxx
nohup sh mqbroker -n 172.17.0.11:9876 autoCreateTopicEnable=true -c conf/broker.conf &
