One of the objectives of AMPstart project is to seperate PHP applications and database from the web server (XAMPP package). The most ideal one is to set XAMPP package on CD (read only), PHP applications and database on USB (read/write).
The above idea is completely available on USB U3. This USB type has 2 partitions including one having CD format.
To create CD partition of USB U3, use LP Installer downloaded from www.u3.com (and certain skills)
We put XAMPP package (without the folder data of MySQL) and AMPstart.exe on CD partition,
On USB partition, we create the folder www2 containing the folder data of MySQL and the folders of PHP applications.
AMPstart.ini is set at root of USB with the content similar to the following:
[MYSQL]
;point to the folder data of MySQL
folder=\www2\data
[WEBSITE]
;point to PHP applications
website=\www2\PHPapp1,\www2\PHPapp2
;filename is open when web server is launched
homepage=index.php
[ENV]
;environment variables
Then, AMPstart running on CD partition will read configuration file AMPstart.ini on USB partition and work as being set.
