What is Apache
   Open Source HTTP Server that serves any HTTP
    request developed by numerous developers around
    the globe now coordinated by a non-profit
    organization called the Apache Foundation.

   Apache has been written in C, using a dynamic,
    modular architecture (much like
    the kernel module architecture) in which pieces of
    functionality can be
    inserted into the web server by loading pieces of
    code known as modules.

History of Apache
   The first version of the Apache web server was created by Robert McCool, known
    simply as NCSA HTTPd before 1994.
   1995: After Robert McCool left NCSA, Brian Behlendorf started collecting
    patches to be applied to the last version of NCSA. The initial versions of Apache
    are available primarily as a series of patches. Hence, initially, the name Apache, as
    it was "a patchy server". At least, so the legend goes.
   April of 1995: The first public release of Apache (version 0.6.2) came out.
   December 1, 1995 : Apache 1.0 released and within a year surpassed NCSA as the
    most-used web server.
   June of 1999:The Apache Software Foundation was formed.
   March, 2000: ApacheCon was held in Orlando Florida, USA. Apache 2.0 Alpha 1
    was released
   …. January 19, 2008, Apache 2.2.8 Released.
Use of Apache
   Number one web server most widely used. It can be found
    running on almost all server one browses.
   Apache is the web server component of the popular LAMP &
    WAMP web server application stack, alongside MySQL, and
    the PHP/Perl/Python programming languages.
   Apache is redistributed as part of various proprietary software
    packages including the Oracle Database or the IBM
    WebSphere application server.
   Apache is used where content needs to be made available in a
    secure and reliable way.
Use of Apache
   Web developers run apache on local servers
    for development purpose.
   Over 61% of all Internet web servers running
   A far second is Microsoft IIS, with a measly
    19% of market share.
Usage of Apache as Web Server
Why Apache?
   Apache is secure.
   Apache has extensive logging.
   Apache is modular.
   Apache allows you to extend the functionality of your
    web site.
   Dynamic sites are easy with Apache. (Java servlets,
    PHP, PERL, Python)
   URL rewriting, access control and authentication,
    setting of non standard HTTP headers, server-side
    includes, CGI support, server side image map
    support, proxy and caching support etc.
Requirement & Specifications
   A computer running Linux (or windows also)
   Root access on this computer
   For binary and source installations, the tar and
    gunzip Unix utilities
   To actually run a server – a huge space and
    high bandwidth internet connection is
Alternatives to Install
   Source Distribution
       Consists of the source code and no pre-built
       Maximum flexibility to custom configure and
        install Apache
       Latest bug fixes and feature enhancement
Alternatives to Install
   Binary Distribution
       Consists of pre-built binaries for the various
        supported operating environments and platforms.
       As binaries are pre-configured, much opportunity
        to alter the way the software works is not
       Can be installed in 3 commands
Alternatives to Install
   Packaged distribution
       Come in packaged formats like
        RPM (for RedHat and derivative systems)
       Installed via the standard installation management
        program called rpm that allows the software
        installation of Apache to be tracked by the
        Operating System.
Installation – Binaries
   Get apache from http://www.apache.org/dist/httpd/binaris/
   Unzip the archive
       gunzip < httpd-2.2.8.tar.gz | tar xvf –
       Or tar xvzf httpd-2.2.8.tar.gz
   Move to the directory obtained
       cd httpd-2.2.8
   Find install.bindist.sh. or README.bindist
or INSTALL.bindist for further information
 Run the install script
       ./install.bindist.sh
Installation – RPM
   Find rpm in your system
       rpm -qa | grep apache or rpm -qa | grep httpd
   Obtain rpm from
   Navigate to the directory where the rpm is
   Install the rpm
       rpm –ivh httpd-2.2.3-1.i386.rpm
Installation – Source
   Obtain source archive from
       http://www.apache.org/dist/httpd/
   Unzip the archive
       gunzip < httpd-2.2.8.tar.gz | tar xvf –
   Navigate to installation directory
       cd httpd-2.0.x
   Configure build and install with
       ./configure
       Make
       make install
Starting Apache
   For binary installation
       /usr/local/apache/bin/apachectl start
   For RPM installation
       /sbin/service httpd start
   To stop apache use
    /usr/local/apache/bin/apachectl stop
   Configuration files are
       ·httpd.conf – This has the settings for the overall
        configuration for the server.
       ·access.conf – This file contains all the security settings
        for Apache.
       ·srm.conf – This file contains the MIME definitions and
        default document names for files on the server.
   DocumentRoot - This is the location of the directory
    from which HTML files are
   To find the conf files
       cd /
       find -name httpd.conf
