1. Change your MySQL ROOT password!
   $ /usr/mysql/5.1/bin/mysqladmin -u root password {{'NewPassword'}}
$ mysql -u root -p

2. Install phpMyAdmin
   $ pfexec pkg set-authority -O http://pkg.opensolaris.org/webstack Webstack
$ pfexec pkg refresh
$ pfexec pkg install pkg://webstack/phpmyadmin
$ man phpmyadmin
$ /usr/bin/phpmyadmin_evaluation_init


Final Configuration of phpMyAdmin:

1. As root:
   # vi /etc/phpmyadmin/config.inc.php
/blowfish_secret
2. In the empty ‘ ‘ after the = type any random string under 46 chars. Doesn’t matter what (AFAIK) and you won’t be asked again (AFAIK).
3. :wq

Point your webbrowser at http://127.0.0.1/phpmyadmin/ and you should be ready to rock & roll. If you have any trouble go back to the origianl Maintainer’s Blogpost and also read the MAN pages more carefully.

You should also familiarize yourself with Sun’s: Web Stack Getting Started Guide

Good Luck!
