The most common protocol used to transfer Web pages is the Hyper Text Transfer Protocol (HTTP). Protocols such as Hyper Text Transfer Protocol over Secure Sockets Layer (HTTPS), and File Transfer Protocol (FTP), a protocol for uploading and downloading files, are also supported.

Apache Web Servers are often used in combination with the <application>MySQL</application> database engine, the HyperText Preprocessor (<application>PHP</application>) scripting language, and other popular scripting languages such as <application>Python</application> and <application>Perl</application>. This configuration is termed LAMP (Linux, Apache, MySQL and Perl/Python/PHP) and forms a powerful and robust platform for the development and deployment of Web-based applications.

The Apache2 web server is available in Ubuntu Linux. To install Apache2:

155.

At a terminal prompt enter the following command: <screen>
<command>sudo apt-get install apache2</command>
</screen>

Apache is configured by placing <emphasis>directives</emphasis> in plain text configuration files. The main configuration file is called <filename>apache2.conf</filename>. In addition, other configuration files may be added using the <emphasis>Include</emphasis> directive, and wildcards can be used to include many configuration files. Any directive may be placed in any of these configuration files. Changes to the main configuration files are only recognized by Apache2 when it is started or restarted.

157.

The server also reads a file containing mime document types; the filename is set by the <emphasis>TypesConfig</emphasis> directive, and is <filename>mime.types</filename> by default.

158.

The default Apache2 configuration file is <filename>/etc/apache2/apache2.conf</filename> . You can edit this file to configure the Apache2 server. You can configure the port number, document root, modules, log files, virtual hosts, etc.

Apache2 ships with a virtual-host-friendly default configuration. That is, it is configured with a single default virtual host (using the <emphasis>VirtualHost</emphasis> directive) which can modified or used as-is if you have a single site, or used as a template for additional virtual hosts if you have multiple sites. If left alone, the default virtual host will serve as your default site, or the site users will see if the URL they enter does not match the <emphasis>ServerName</emphasis> directive of any of your custom sites. To modify the default virtual host, edit the file <filename>/etc/apache2/sites-available/default</filename>. If you wish to configure a new virtual host or site, copy that file into the same directory with a name you choose. For example, <command>sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/mynewsite</command> Edit the new file to configure the new site using some of the directives described below.
