Here are the notes I have from putting SugarCRM 6.5 on SME 8...
cd ~/addons
wget http://downloads.sourceforge.net/project/sugarcrm/1%20-%20SugarCRM%206.5.X/SugarCommunityEdition-6.5.X/SugarCE-6.5.16.zip
unzip SugarCE-6.5.16
mv SugarCE-Full-6.5.16 /ibays/Primary/html/Sugar
chown -R www:www /ibays/Primary/html/Sugar/.
mysql -e "create database sugarcrm; grant all privileges on sugarcrm.* to sugar_user@localhost identified by 'put-your-password-here' with grant option; "
#
#
# browse to website to install
#
# (Note: enter sugar_user and password from above during install)
There are two possible reasons that I'm putting this into a folder in the Primary ibay:
1) Installation into an ibay doesn't work (there are some webapps for which this is the case)
2) I wanted to test quickly, and didn't want to create a new ibay
Sorry; my notes don't say which it is...
