前言
其實每個版本都有些許改動,只不過改動大小而已,但是網上的教程都真的太老了,其實更新一下也費不了多少時間

小結
可以看出,目前最新版本的配置檔案沒有了
#port=9092
#host.name=localhost
#advertised.host.name=<hostname routable by clients>
#advertised.port=<port accessible by clients>
取而代之的是#listeners=PLAINTEXT://:9092
#advertised.listeners=PLAINTEXT://your.host.name:9092
並且新增了一些配置,以及有些地方註釋的說明更詳細。
