its nothing show anything

I followed this article for configure opendkim
http://www.linuxtechi.com/configure-...x-on-centos-7/

Did you look at the log file, as the error told you? It's not starting for a reason, and the logs tell you that reason.

There is AMPLE documentation on how to configure dkim with multiple domains for postfix....

AGAIN...you need to read the LQ Rules. DO NOT use text speak.
...because you DID NOT look in the right place, did you??? Go back and re-read what you posted in your first message. Did it say to look in /var/log/maillog? Or did it plainly say "See "systemctl status opendkim.service" and "journalctl -xe" for details."

Did you actually TRY running "journalctl -xe", as it said, and as it was suggested to you????

Sorry TB0ne
I shared the wrong information(/tail -f /var/log/maillog)

In systemctl status opendkim.service.i found the errors but i dont know how can i solve this issues.please guid me

AGAIN, you are not paying attention.

• The error message you first posted gave you a journalctl command to run...DID YOU RUN IT???? THAT is the log information that you need
• THIS error message gives you a VERY clear message, about not being able to find the file or directory. DID YOU CHECK TO SEE IF THEY WERE THERE???
• You were handed a link with instructions about how to configur DKIM with postfix for multiple domains...DID YOU READ/FOLLOW/UNDERSTAND IT????

You have been 'guided' several times now...if you're not going to read the messages, follow suggestions, or pay attention to VERY obvious things, what's the point in posting?
