Errors while installing Sentora 1.0.3 on CentOS 7

[betatester3.0]

You need to install Sentora on a minimum OS without any services installed, if you not sure about it you can use this: http://docs.sentora.org/?node=105

Sure look into it, something went wrong! lol

I done a clean minimal install, and removed postfix:

this is the new error:
Error no1
