First of all, there is now FREE Solaris 10 media kit available to order by mail if you’re not fancy downloading several GB. By the way, it also includes Sun Studio (anyone using it?). I ordered mine and it should come soon.
Second, I found a cool article on Solaris BigAdmin portal – Deployment Guide for an Open Source Stack on the Solaris 10 OS also available as PDF. It shows how to install MySQL and PostgreSQL as well as Apache, Tomcat and PHP, and integrate them all together. Really simple guide so anyone can do it. Couple interesting bits I found there are tips on performance tuning (unfortunately, not much explained) and how to configure Solaris Zones (but it’s more for Apache installation I believe).
