I want to setup an intranet webserver mainly for Database (MySQL, php) development and use. I want to use an old PC for that. Target is to do some script writing on that server from another PC. What would be a good O/S to chose? My thinking is: Xp - no, I use the old Xp already on another PC CentOS - Our VPS uses CentOS and I have some experience. Ubuntu - we have some Ubuntu PCs in the office and use that too. I don't really need any fancy GUI after installation though. I tend to think that CentOS in combination with XAMPP would be a good idea. Performance and security is no issue for now. However, I do use old hardware (AMD 600 MHz or so, 750Mb RAM) Shall I stay with CentOS or any other suggestion?
