Depends on the distribution.

For Red Hat, derivatives and other RPM-based distro's, you can type:

rpm -qa

For Debian and derivatives, you can type:

dpkg -l

Both will show a list of all installed packages on the machine.

Specifically for you requirements, I'd do the appropriate one and grep -i on httpd (Red Hat) or apache (Debian et al.), php and mysql.

If you know the specific package name rpm -q httpd is faster because the search is narrowed. But rpm -qa will give you a little more flexibility if you don't specifically know the package name. – Alex Sep 3 '10 at 15:53
rpm -qa showed me lots of information, but didnt mention php or apache, whereas php is definitely installed (I was able to run it from the command prompt) – TWord Sep 4 '10 at 7:10
On RHEL, the Apache package is called httpd. The OUtput of rpm -qa should mention php. – wzzrd Sep 4 '10 at 10:49

Perhaps you'd like to know which software was installed lately. If so, then run rpm -qa --last | tac. This shows all installed packages in chronological order.

For redhat/centos/fedora rpm -qa might be what you are looking for.

If you have a GUI installed on a Debian box, you can use synaptic. There is a preconfigured filter to show all installed packages.
