Solaris is a UNIX Operating System much like any other flavor of UNIX. There are differences compared to Linux and the BSDs
(FreeBSD, NetBSD and Darwin) but they don't take long to get used to.
We just want to touch on a few common ones:
Startup scripts can live in /etc/init.d/ and in “SMF”. You can also use standard startup scripts in /etc/init.d/ or you can use SMF. Some key things are already SMF'ed. You can see which ones have SMF manifests in the system by typing “svcs -v”. For example, notice that
SSH is there, this means that if you change the configuration file in /etc/ssh/sshd_config, then you “refresh” it with “svcadm refresh ssh”.
There isn't a “cc” that ships with Solaris (it's a separate compiler download), but all the gcc's are there in /opt/csw. This is most notable when you are say trying to compile a gem that goes out and looks for “cc” and doesn't find it. The solution for this particular case is to have the rbconfig.rb point to gcc. If you are running Ruby 1.8.4 then you can replace it with:
svn export http://svn.joyent.com/public/accelerators/rbconfig.rb.184 /opt/csw/lib/ruby/1.8/i386-solaris2.8/rbconfig.rb
If you are running Ruby 1.8.5 then you can replace it with:
svn export http://svn.joyent.com/public/accelerators/rbconfig.rb.185 /opt/csw/lib/ruby/1.8/i386-solaris2.8/rbconfig.rb
pkg-get -i nano
Honestly there's not much more than that. But if you've got a question that hasn't been covered here, trying adding it to our FrequentlyAskedQuestions page.
