ROCKETMQ Broker Chapter III Registration process

Hi everybody good last two chapters introduced the NAMESRV start and the registration process, has what is wrong place to welcome everybody to vomit the trough, then starts analyzes the broker bar

There are some places that can't be painted. Look at the details by analysis.
