Best Light server (Linux + Web server + Database) for Raspberry Pi [on hold]

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 and web server and 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 (memory usage, disable plugin, disable service, etc)?

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