Apache Missing from Solaris 10

If you find you are missing your ‘built in’ apache2 installation, go back to your install media (or jumpstart image) and get the following packages:

Apache: SUNWapchS, SUNWapchd, SUNWapchr, SUNWapchu

Apache2:SUNWapch2S, SUNWapch2d, SUNWapch2r, SUNWapch2u

Install each using pkgadd.  Once you have done that, perform a kill -HUP on your /lib/svc/bin/svc.configd process (ps -ef |grep svc to get the processs id). or you will end up with a “svcadm: Pattern ‘apache2′ doesn’t match any instances” error when you run the svcadm startup command. 

Which happens to be: svcadm enable apache2
You’ll probably want to configure the /etc/apache2/httpd.conf as well.  (just copy over the /etc/apache2/httpd.conf.example and edit the ServerName and ServerAdmin as a start.)
