mysql and postgresql

[varun_33]

What are the minimum hardware requirements for installing postgresql and mysql on a linux Machine(example:Red Hat Enterprise Edition)...

It depends largely what you want to do with it.
Large databases need much space and CPU/memory.

I have a LAMP application server running on a PII-400 with 512MB ram and a 30GB hdd. mysql is used as backend fot phpBB2 and mambo (like this forum) and has now a 2 databases of about 7MB each which forforms still adequate for it's use, although cpu is now up to 97% when adressing the database(s).

I know a heavily visited forumsite which has:
two athlon 64 with 1GB ram each as front-end
three dual operons with 4GB ram each as back-end.for MySQL

In my opinion it's better to use either mysql or postgres than both

SQLite is FAST if you want a small, fast alternative that runs great even on a 486.
