The Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems including UNIX and Windows NT. The goal of this project is to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards.

===Install apache2===

<code>
apt-get install apache2
</code>

==Install openssl using the following command==

<code> 
apt-get install openssl ssl-cert
</code>

**Install PHP5 support for apache2**

<code>
apt-get install php5 libapache2-mod-php5 php5-cli php5-common php5-cgi php-mdb2 php-gettext smarty
apt-get install php5-intl php-auth php-mdb2-driver-mysql 
Optional ????javascript-commondb config-common libjs-codemirror
</code>

Once you install apache server you need to Generate a certificate,Enable Apache SSL support and Configure your SSL options.
==Generate A certificate==

Generating a certificate will provide to protect the traffic exchanged between clients and your server, however it will be unsigned by a trusted certificate authority so it will generate warnings. \\ 

If you want to avoid these warning messages you need to get a trusted certificate from SSL certificate vendors.If you want to Generating an SSL certificate for Apache2 you need to use the openssl. This will ask you questions interactively then generate the certificate file appropriately. \\ 

Note:-For generating certificate you might have used the apache2-ssl-certificate command in debian sarge but in debian etch this command not available.If you want to generate certificates you need to use openssl from you command prompt Use the following command to generate certificates\\ 

<code>
openssl req $@ -new -x509 -days 3650 -nodes -out /etc/apache2/apache.pem -keyout /etc/apache2/apache.pem
</code>

Generating a 1024 bit RSA private key\\ 
.................................................++++++\\ 
...........................................++++++\\ 
writing new private key to ‘/etc/apache2/apache.pem'\\ 
-----\\ 
You are about to be asked to enter information that will be incorporated\\ 
into your certificate request.\\ 
What you are about to enter is what is called a Distinguished Name or a DN.\\ 
There are quite a few fields but you can leave some blank\\ 
For some fields there will be a default value,\\ 
If you enter ‘.', the field will be left blank.\\ 
-----\\ 
Country Name (2 letter code) [AU]:DE\\ 
State or Province Name (full name) [Some-State]:Hessen\\ 
Locality Name (eg, city) []:FFM
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Ramazotti Hot Spot\\ 
Organizational Unit Name (eg, section) []:\\ 
Common Name (eg, YOUR name) []:\\ 
Email Address []:\\ 

This will complete the certificate now you need to make sure you have the correct permissions for .pem file if not use the\\ 

following command to set the correct permissions\\ 

<code>
chmod 600 /etc/apache2/apache.pem
</code>

==Enable HTTPS Port==
By default the server will listen for incoming HTTP requests on port 80 -- and not SSL connections on port 443. So you need to enable SSL support by entering the following entry to the file /etc/apache2/ports.conf save and exit the file.

/etc/apache2/ports.conf
<code>
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default
# This is also true if you have upgraded from before 2.2.9-3 (i.e. from
# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and
# README.Debian.gz

NameVirtualHost *:80
Listen 80

<IfModule mod_ssl.c>
    # If you add NameVirtualHost *:443 here, you will also have to change
    # the VirtualHost statement in /etc/apache2/sites-available/default-ssl
    # to <VirtualHost *:443>
    # Server Name Indication for SSL named virtual hosts is currently not
    # supported by MSIE on Windows XP.
    Listen 443
</IfModule>

<IfModule mod_gnutls.c>
    Listen 443
</IfModule>
</code>

<del>
Listen 443</del>\\  \\ 

==Enable SSL Support==

If you want to enable SSL support for your apache web server you need to use the following comamnd

<code>
a2enmod ssl

Module ssl installed; run /etc/init.d/apache2 force-reload to enable.
</code>
Now you need to restart the apache2 server using the following command

<code>
service apache2 restart
</code>

**Configuring SSL Certificate to Virtual Hosts in Apache2**

First you need to edit the /etc/apache2/sites-available/default file change

/etc/apache2/sites-available/default
<code>
<VirtualHost *:80>
	ServerAdmin webmaster@localhost

	DocumentRoot /var/www/http
	<Directory />
		Options FollowSymLinks
		AllowOverride None
	</Directory>
	<Directory /var/www/>
		Options Indexes FollowSymLinks MultiViews
		AllowOverride None
		Order allow,deny
		allow from all
	</Directory>

	ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
	<Directory "/usr/lib/cgi-bin">
		AllowOverride None
		Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
		Order allow,deny
		Allow from all
	</Directory>

	ErrorLog ${APACHE_LOG_DIR}/error.log

	# Possible values include: debug, info, notice, warn, error, crit,
	# alert, emerg.
	LogLevel warn

	CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

<VirtualHost *:443>
        ServerAdmin webmaster@localhost

        DocumentRoot /var/www/https
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
        </Directory>

        ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
        <Directory "/usr/lib/cgi-bin">
                AllowOverride None
                Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
                Order allow,deny
                Allow from all
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log

        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn

        SSLEngine on
        SSLCertificateFile /etc/apache2/apache.pem
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

</code>


==Configure different index.html for http and https in Virtual Hosts in Apache2==
<code>
root@raspberrypi:/var/www# mkdir http
root@raspberrypi:/var/www# mkdir https
root@raspberrypi:/var/www# cp index.html http
root@raspberrypi:/var/www# cp index.html https
root@raspberrypi:/var/www# cd https/
root@raspberrypi:/var/www/https# vi index.html 
</code>

Now you need to restrat your apache web server using the following comamnd\
<code>
service apache2 restart
</code>
\\ \\ 
<del>/etc/init.d/apache2 reload</del>\\ 

Reloading web server config... XXXX

\\ \\ 
To test the php5 installation and appache2 create a file named e.g. phpinfo.php in the root directory of the www-server.\\ 
Content:

<code>
<?php
phpinfo();
?>
</code>
