Fedora Linux vs. CentOS for mission critical web server
We just ordered a Dell PowerEdge 1800 Server with these specs:
- 2.8GHz/2MB Cache, Xeon 800MHz Front Side Bus for PowerEdge 1800
- 2GB DDR2 400MHz (4X512MB) Single Ranked DIMMs
- 80GB 7.2K SATA HDD, PE1800
- On board Network Adapter
- 48X IDE CD-ROM
- Motherboard SATA, PE1800
- Tower Chassis, PE1800
- Non-Redundant Power Supply PE1800
We need to configure it to run one website with about 6,000+ unique visitors daily and 2GB average daily traffic. Need the basics for the web server, Apache, PHP, MySQL, also need Postfix, IMAP/POP3, MailScanner/SpamAssasin (for the spam blocking), AWstats, Webmin, etc. It also runs a heavily used vBulletin board (over 2K posts daily). The DB for that board alone is more than 1GB.
We need to choose between Fedora Linux and CentOS (based on Red Hat Enterprise Linux source). Since this is a mission critical server with heavy load (and a very popular local site here in Puerto Rico) we need to choose a distro that is very stable, secure and easy to update. Between these two, which one would be the wiser choice to use on this server?
All suggestions and comments are welcome…
