I have installed Squiz Matrix many many times, but I was getting tired of going through the same steps every time I needed to install it. So, I wrote a shell script that does everything for you, including installing dependancies and external tools.
The process takes about 5 minutes. This has been tested on Debian Squeeze.
Usage
sh /path/to/script/squiz_matrix_install.sh
Options
ROOT_URL="192.168.163.131" DEFAULT_EMAIL="me@website.com" PATH_TO_MATRIX="/home/websites" APACHE_USER="www-data" SQUIZ_MATRIX_VERSION="mysource_4-14-1"
