oracle 5u6 and phpmyadmin

the oracle 5u6 repos seems to missing  php-mcrypt so you can’t directly install and run phpmyadmin !

what i had to do was

• add centos 5 yum repo
• rpm –import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
• add rpmforge yum repo
• yum install php-mcrypt (from centos repo)
• yum install phpmyadmin (from rpmforge repo)

and then

• edit /etc/httpd/conf.d/phpmyadmin.conf to allow my IP
• service httpd reload
