done by nethserver-phpscl, yet only for ns6
I would in the future base all my work on php-fpm and get rid of php-mod
it exists also for ns6 and ns7, install nethserver-phpmyadmin, it is the purpose of this software.
all relative documentation to install external modules are there http://wiki.nethserver.org/doku.php?id=modules
May I suggest that you install first nethserver-shellinabox, you will have a terminal in your web browser where you can copy and paste command like in your terminal.
