First of all, I'm not an Linux/DirectAdmin expert. I just played around with them and found the way to do it. I tried to install Cacti on my server but I couldn't find a complete instruction to do it. So, I just gathered all information I found into one place so that it is easier for many others. I hope it can help someone that needs the same thing that I did.
The software I use:
- CentOS 5.2 - 64-bit
- DirectAdmin 1.323 - Custombuild 1.1.13
- PHP 5 - CGI
- Apache 2.2
- MySQL 5
- Cacti 0.8.7b
