minimal set of users?

[mdudu]

I am very new to linux but am familiar enough with unix to at least know my way around from a user perspective (ie man pages, setting up my shell etc). However I need to admin a new linux box (it already has linux installed and ssh setup) and I need to setup DNS, apache, php/perl, mysql, moodle, and sendmail.

I think I can handle the installs, what I need to know is what is the minimal set of users I should create? The only user on there now is root and I feel like I need to have a "webapps" user or something like that under which all these apps (apache, mysql, etc) will run. Should I have a seperate user for moodle and php as well? Should I have a seperate "web admin" and "web developer" user? The latter for when I need to upload new scripts, html, etc when developing applications.

Any guidance or pointers to resources would be great! thanks.

If you install MySQL, Apache and most server apps using your distributions packages, then dedicated users for those apps are automatically created for you (look in /etc/passwd).
