Linux UnixWindows Linux: Where Unix meets Windows GUI based approach to Apache installation.
Apache Configuration Using KDE 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 internal LAN.
Using ktail to Monitor Installation 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 configurationktail
Launching ktail to Monitor the Installation Alt F2 opens a mini command line
Other Details on Access Log The machine's name or IP address that accessed the server Date and time of access The file that was transferred An access code and the number of bytes transferred The server's name or IP address that was requested The web browser that was used And some info about the visitor's system
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.
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. continued
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 page
Creating index.php3 for Testing of php3 Support
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.phpbuilder
Absence of index File A directory listing is displayed as shown in the previous slide in the absence of an index file
Activating Configuration Changes 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 restart GUI –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 Numbers Standalone is recommended for server type 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
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
Changing Permissions Show entries and change into commands will give public to enter the folder and view its contents
Summary Windows users may still use some of the techniques learned to configure and operate Linux operations However, some command line programming is still inevitable In the long run, more GUI based operations is likely to be introduced in Linux
