delete port field when init sequelize

[toozhuang]

Hi Mate,

When I do this on my local follow your tutorial, I got some connection error when init the sequelize with setting port filed. And when removed this, connection worked well. port: '8006'

Hi @wangtoday, you will need the portnumber if you work with docker for example. You can just remove it when not using it.
