Install Apache if Necessary

Description

If httpd was not installed and activated, but the system needs to act as a web server, then it should be installed on the system. Follow these guidelines to install it defensively. The httpd package can be installed with the following command:

$ sudo yum install httpd

This method of installation is recommended over installing the "Web Server" package group during the system installation process. The Web Server package group includes many packages which are likely extraneous, while the command-line method installs only the required httpd package itself.
