did not find cpanel3 ap /etc/rc.d/init.d/ after complete the installation

I complete the installation of cpanel but when I browse to http://domain.com:8023, it fails.

I try to start at /etc/rc.d/init.d/cpanel3 but i don't find this script.

I also try service cpanel start, but get error too.

How can I solve this problem?

I tried to install again but still didn't solve.

OS is redhat7.2
thx

 

sorry typo error:
browse to http://domain.com:2083 and it fails ........
thx

 

I have already tried 2082 and 2083(https) but it fails.

I didn't find any service for cpanel on the server. What's wrong for the installation?

 

I re-install it third times, still don't find the cpanel3 starting script at /etc/rc.d/init.d/

what's wrong?
any suggestion?

thx
