You can try the whereis command if you know the name of a binary a program uses. For instance, for apache2, you could issue whereis apache2. My output for that command is:
apache2: /usr/sbin/apache2 /etc/apache2 /usr/lib/apache2 /usr/include/apache2 /usr/man/man8/apache2.8.gz /usr/share/man/man8/apache2.8.gz
Unfortunately, it won't give you the document root or anything, but it's a start.

Also, I'm not sure about Redhat, but on most systems, these paths are common:
Apache data: /var/www
Apache config: /etc/apache or /etc/apache2
MySQL data : /var/lib/mysql

My Java is installed at /opt/blackdown-jre-version.

I hope that helps.

Wink Thanks for the Help!!

Thanks for the kindly help Zoombie, the "whereis" command are really helpful.

I have been trying some testing on my machine, the funny thing is when i key
in "whereis apache2" in the terminal its cames out with a result "apache2:"
.. there is no furthur details on the directory.. but when i key in "whereis httpd"
it display the result which is similar with you.. namely;

/usr/sbin/httpd.worker /usr/sbin/httpd /etc/httpd /usr/lib/httpd /usr/include/httpd /usr/share/man/man8/httpd.8.gz
Untitled 1

.. maybe we are using 2 different distribution.. anyway, i am very appreciated of your reply. Thanks

You can also use the find command to look for files/binaries...


find / -name <fileyourlookingfor> -print

That should search the system. You can also wildcard it so if you know that the file has say, "word" in it's name but you're not sure, try:

find / -name *word* -print

Hope that helps!

'locate' is good too, and usually faster than find since it works off a database rather than searching the directories.

I can't ever use "find" because I'm always told to updatedb as root, and I've tried
typing as root "updatedb" because it sounds like a command but that isn't quite right.
"Locate" does the trick for me.

"updatedb" is just the command to update the database "locate" uses.

It is usually run by cron.daily though I put it into cron.monthly and start it by hand when necessary.
