     Apache Configuration Using

• In this section, Apache will be
  configured using the available tools
  and utilities of the KDE desktop.
  This is not necessarily a
  recommended way to run a web
  server, but it does offer a
  convenient environment to begin
  learning the first steps of running a
  web server in the safety of an

             Using ktail to Monitor

• Alt-F2 will open a mini-command line
  in KDE, and kdesu -c ktail will launch
  ktail as the root user.
   Ktail will be used throughout the
  following pages to monitor Apache's
  log files during configuration

                    Location of conf Files

A copy has been made of the conf files folder
  Making a Copy of the Conf Files
• /etc/httpd/conf is where Apache's
  configuration files are located.
   You may want to first make a backup copy of
  the original configuration directory before
  making edits to the enclosed files.
   Ctrl-t opens a konsole in the current
  directory, and cp -r conf confOrigBackup
  recursively copies the folder & contents with
  a new name.

Section1: Modules
                  A Note on Modules
• This first section of Apache's
  configuration file deals with modules.
  Modules add extra capabilities to Apache
  that aren't normally included in its basic
  set of features.
   If you install Mandrake's RPM modules
  for Apache you most likely won't ever
  need to manually enter any module
  information yourself, as the required
  entries will automatically be added with
  the packages.

       php3 Module: An Example

• mod_php3 is a module that enables
  this popular scripting language to be
  used with Apache.
   If mod_php3 is installed on your
  system, you can test it by creating a
  simple test page as seen on the next
Creating index.php3 for
Testing of php3 Support
Testing for php3
      Success in Testing for php3

• You can test Apache by loading the
  page into Netscape.
   If php3 wasn't enabled properly, a
  screen of raw text would appear
  instead of a normal looking web
  page as seen here.
        A Note on Testing for php3

• This is just a quick way to demonstrate if
  php3 is enabled on a server. php3 is a
  full-featured, HTML-embedded scripting
  language used for creating dynamically
  generated web pages.
   One common use of php3 is as a
  replacement for CGI scripts.
  Unfortunately this topic can't be covered
  in detail on these pages. For more info on
  php3, phpbuilder is a good starting point.
 Location of Web
Documents (Root)
                       Document Root

• The document root is where the web
  pages of the active website are kept
  – Similar to the home directory of the www
    server in Windows

                Absence of index File

• A directory listing is displayed as
  shown in the previous slide in the
  absence of an index file
          Activating Configuration

• After every configuration change
  Apache must be restarted
• It is usually a good practice to make one
  change at a time and then check ktail to
  ensure that the change had been made
  without any errors before proceeding to
  make the next change
                Starting, Stopping and
                    Restarting Apache

• Commands
  – apachetl start, apachetl stop, apachetl
  – Apache may also be started, stopped and
    restarted through the control services GUI
     • Access the httpd service for this purpose

    Note on Server Type and Port
• Standalone is recommended for server
• Information on port numbers can be
  found in /etc/services
• Users do not have to enter a port
  number on the address if default port
  numbers are maintained
  – Example is Port 80 used for www service
            Phantom User Nobody

• Apache runs as a phantom user known
  as nobody with very limited access
• Anyone exploiting this name to gain
  access to Apache will severely be
  restricted from causing any damage
Location of Apache
            A Note on Server Name
• Server name is the one seen by the
  browsers in the filed “location name”
• For hosting a name accessible over the
  Internet, the name must have been
  registered and it must have a DNS
  entry on a DNS sever
• Server name need not relate to the
  machine’s host name

       A Note on Changing Name

• In general, changing host names should
  be avoided
• Certain services are configured based
  on the host name and they may not
  function properly after changing the
  name of the host
