Solution

If you are a member of the Red Hat Network (RHN), Red Hat’s
subscription service, you can use Red Hat’s up2date tool to maintain
your Apache package:
# up2date -ui apache apache-devel apache-manual
If you’re running a more recent version:
# up2date -ui httpd httpd-devel httpd-manual
If you aren’t a member of RHN, you can still download the packages
from one of Red Hat’s servers (either ftp://ftp.redhat.com/ or
ftp://updates.redhat.com/), and install it with the following
command:
# rpm -Uvh apache

Discussion

The -Uvh option to the rpm command tells it to:
Upgrade any existing version of the package already on the
system or install it for the first time if it isn’t.
Explain the process, so you can receive positive feedback that
the installation is proceeding smoothly.
Display a pretty line of octothorpes (#) across the screen,
marking the progress of the installation.
If you use the packages Red Hat maintains for its own platform, you
will benefit from a simple and relatively standard installation.
However, you can only update versions that Red Hat has put together
an RPM package for, which typically means that you may be lagging
weeks to months behind the latest stable version.
There is also the issue of platform compatibility; for instance, at
some point the version of Apache provided for Red Hat Linux changed
from 1.3 to 2.0, and newer versions of the operating system will
probably only have the 2.0 packages available. Similarly, if you run
an older version of Red Hat Linux, the newer packages will probably
not install properly on your system.
It’s a good idea to install the apache-devel package as well. It’s quite
small, so it won’t have much impact on your disk usage; however, it
includes files and features that a lot of third-party modules will need
to install properly.
