Sweet and salty popcorn best describes Nexenta. OpenSolaris kernel but still using many GNU tools and such: the best of both worlds. The balls robustness of Solaris with easiness of the GNU userland, Debian to be specific, makes it easy to use Solaris. I've just got it running and I quite love it. I love Debian by itself, especially for apt-get.
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.
After experimenting with Solaris 10 for a bit, I thought I'd get iStat on there so I can see it's activity on my iPhone. After getting down and dirty with Solaris for a bit, I definitely learned some things. Since iStat needed libxml2, I grabbed that from Sun Freeware and installed it fine. Next thing was to, of course, install the iStat client. When I ran ./configure it was complaining about not being able to create a C++ executable. And with gcc already installed, libraries were the issue. /usr/bin/crle -c /var/ld/ld.config -l /lib:/usr/lib:/usr/local/lib:/usr/local/ssl/lib did the trick.
