#创建broker配置文件
vim /learn/rmq/rmqbroker/conf/broker.conf
brokerIP1=172.16.55.185
namesrvAddr=172.16.55.185:9876
brokerName=broker_haoke_im
#启动broker，通过 -c 指定配置文件
bin/mqbroker -c /learn/rmq/rmqbroker/conf/broker.conf
The broker[learn, 172.16.55.185:10911] boot success. serializeType=JSON and name
server is 172.16.55.185:9876 #这样就可以进行访问了
