"What else do I need?
Rails works with a wealth of web servers and databases. For web
server, we recommend Apache or lighttpd running either FastCGI or
SCGI. For database, you can use MySQL, PostgreSQL, SQLite, Oracle, SQL
Server, DB2, or Firebird. Just about any operating system will do, but
we recommend a 'nix-based one for deployment."
