I wanted to set up a development server to test more intensive PHP applications, and also a sandbox so I opted to get a typical web server stack on Solaris.
First thing's first: grab nginx from Cool Stack page. There's some great packages there, like Apache, PHP and MySQL all in one. I decided to go with nginx for something light and something new.
The binary for nginx is /opt/coolstack/nginx/sbin/nginx so be sure to set your configuration in /opt/coolstack/nginx/conf/nginx.conf (pretty straight forward). Be sure to enable the FastCGI section in the config file!
