Best Light server (Linux + Web server + Database) for Raspberry Pi

I would like to install a web server with a database on a Raspberry Pi (little computer). The computer has only 1GB RAM.

I want to know what is the best combination : Linux distribution + web server + DBMS to run the local server with multiple users with minimal latency, I will use PHP on the server. And what are the best settings for good performance and to not have bugs.

I thought a light Debian , a lighttpd server and SQLite for the database. Is this is a good solution?

Sorry for my English.
