I was finally able to install Apache 2.2.6 on my Red Hat Enterprise Linux 4 box by uninstalling the version that came with it (2.0.59) and downloading and installing the Apache 2.2.6 files from Apache's website. If I open a browser and go to localhost, the screen reads "It Works!", so it looks like apache is installed, but why is there no httpd service under services? Also, when I type in "rpm -q httpd", it says "package httpd is not installed". The file I downloaded from the Apache website was the httpd-2.2.6.tar.gz file. I did the whole "./configure, make, make install, apachectl start" and it worked, I guess, but why no httpd service? Thanks.

If you install a package from source, RPM will not know about it. It only knows about packages that were installed via the rpm command (and related tools such as yum etc). Since you compiled from source, you have to setup the httpd service on your own. You can do this by copying the apachectl file to /etc/init.d and do
You may have to edit apachectl so that it works correctly on your system.

Building and installing software from source tarballs will not be reflected in RPM's knowledge of what is installed. Only packages installed by rpm will be known to it.

You may have to configure apache to start and stop as a service by creating and adding the appropriate shell scripts to the /etc/rc.d/..... directories. Installing apache as an RPM might have done this for you. Examine the files and directories in /etc/rc.d and its subdirectories, and also the man page for chkconfig. I believe the 'apachectl' script can be set up as a service, and is probably intended as such.

Thanks for the reply. Can you give me some more detail, here? I copied the apachect1 file to /etc/init.d. When I ran the "chkconfig --add httpd" I got an error message: "error reading information on service httpd: No such file or directory". I'll logged in as root. Which directory do I need to run the chkconfig command from? I tried it in a bunch of different directories, but nothing worked. Thanks.

Not the latest releases, but Apache webserver is also available as RPM:
http://apache.linux-mirror.org/httpd/binaries/rpm/

Generally it is wise to use RPM in RHEL to ensure one can remove and update packages cleanly.

However if you use own packages you will not benefit from official Red Hat httpd updates that are thoroughly tested and tend to be very secure and stable.

When you copy apachectl to /etc/init.d, you have to rename it to httpd. When you run chkconfig, it does not matter which directory you are in.
