Using your steps, I can setup and access the /cp/admin/admin using 'coraadmin' for Username & Password. All password on the database are hashed, for security purpose. So they can't be used by unauthorized person. First, make sure you have install it on your CentOS:
yum -y install httpd httpd-devel
Start it by using:
/etc/init.d/httpd start
Edit the httpd configuration on /etc/httpd/conf/httpd.conf save and restart by using:
/etc/init.d/httpd restart
or
service httpd restart
