If your system is running Fedora Core or Centos, you probably have YUM installed and can use it to install
Apache HTTPD and Perl. To install these packages using YUM, type the following commands as user root and follow directions.
yum install httpd
yum install perl
Note: The loading and installation of these programs can require a bit of time.
If your system does not have YUM installed (Redhat 7.3 or 9), you will need to get and install the Apache and Perl programs
yourself. Information about these programs is available at these websites.
