I've found the answer, just added some steps to another solution:
1 step - chnaging the http default port :
a- go to /etc/httpd/conf/httpd.conf
then change Listen 80 to any port rather than 80
b-go to /etc/httpd/conf.d/issabel.conf
then comment the lines by adding #
#<Directory "/var/www/html">
Redirect administration interface to https
#RewriteEngine On
#RewriteCond %{HTTPS} off
#RewriteRule (.*) %{HTTP_HOST}%{REQUEST_URI}
#</Directory>
now we changed the http port
then we need to do from console =====> service httpd restart
2 step -changing the https default port
a- go to /etc/httpd/conf.d/ssl.conf
then change
Listen 443 to anyport ranther than 443
b- go to /etc/httpd/conf.d/ssl.conf
then change
VirtualHost default:443
just change the 443 to any port rather than 443
then finally type from console
service httpd restart
