Check your httpd.conf file; it defines which user Apache runs as:
12:57:04pm :chris% egrep "^(User|Group) " /etc/httpd/httpd.conf
User www
Group www
12:57:07pm :chris%

I *think* this is set by your mysql.conf file, though at the moment I can't find where
that file was installed. The closest I can find is a
/usr/local/sql-bench/limits/mysql.cfg, which seems close but not right.
'course you could also get that from "ps -aux | grep mysql", but that's now how you'd
go about changing it, if that was your goal...

If you're going to need it repeatedly, then you can switch to the super user with
"su", but staying in that mode for long is a bad habit. Adding "sudo" to the beginning
of each line is tedious, but generally safer (if nothing else, it logs your actions,
so if you trash things there will hopefully at least be a record of what happened... :)

It may well be running under user "nobody" -- the idea there is that no one can log
into your machine under the web server's running account, because that account doesn't
actually exist (or if it does exist, it's very restricted). You can see what apache
(or anything else) is running as by running "ps aux", and optionally filtering it with
a grep or two. On my machine, I show:
2:33:12pm :chris% ps aux | grep httpd
root 222 0.0 0.0 3440 44 ?? Ss 0:47.31 /usr/sbin/httpd
www 225 0.0 0.0 3440 16 ?? S 0:00.00 /usr/sbin/httpd
www 226 0.0 0.0 3440 16 ?? S 0:00.01 /usr/sbin/httpd
www 227 0.0 0.0 3440 16 ?? S 0:00.00 /usr/sbin/httpd
2:33:18pm :chris%
thus apache launches as root, then runs as user "www". (And this is just a
confirmation of what /etc/httpd/httpd.conf says anyway.)
>and what if there are no username for an application like apache or
>mysql, i mean if username= super user?
Generally those will run as root (super user & root are basically the same thing),
though I think it's possible to run as a nonexistent user (e.g. nobody).
