Enabling SSL For The ISPConfig 3 Web Interface on Centos 5.7 86-64 Bit Linux

I read the manual
Section
6.2 Enabling SSL For The ISPConfig Web Interface

I use Centos 5.7 64 Bit. Manual is for Other linux OS.

I'd like to know how to turn on SSL https://ip:8080/

Please help me.
I like HowtoForge Forum. I can install ispconfig3 on centos 5.7 successfully except https web panel configuration.

Thanks for making great website control panel.
