http://serverfault.com – I am planning on renting a VPS. How much memory is required for a base setup of Debian, Apache, Mysql, PHP? By base, I mean not considering traffic (which will be below 1k hits a day). No complicated databases or memory eating scripts. For reference, I would consider 512MB more than I need. (But i'm unsure of how right I am.) Possible duplicate: How much VPS ram would I need to run Wordpress, Apache, SVN & MySQL? The difference would be, I am specifically asking about Debian, Apache, Mysql and PHP by default Debian configuration. No memory tweaking or replacing Apache with a lighter (HowTos)
