<title>Introduction to <application>Apache</application></title>

<para>The <application>Apache</application> package contains an
open-source <acronym>HTTP</acronym> server. It is
useful for creating local intranet web sites or running huge web serving
operations.</para>

<title>Installation of <application>Apache</application></title>

<para>For security reasons, running the server as an unprivileged user and group is strongly encouraged.</para>

<screen><userinput><command>groupadd apache &amp;&amp;
useradd -c apache -d /dev/null -g apache -s /bin/false apache</command></userinput></screen>

<para>The following patch will define the layout of destination directories
and, among them, the build directory at
<filename class="directory">/usr/lib/apache/build</filename>. This 
will allow the modules added to <application>Apache</application> to
be configured without errors. Apply the patch:</para>

<screen><userinput><command>patch -Np1 -i ../httpd-&apache-version;-config.patch</command></userinput></screen>

<para>Build and install <application>Apache</application> by running the following commands:</para>

<screen><userinput><command>./configure --enable-layout=LFS \
            --enable-mods-shared=all &amp;&amp;
make &amp;&amp;
make install</command></userinput></screen>

<sect2>
<title>Command explanations</title>

<para><parameter>--with-expat=/usr</parameter>: Uses system installed
expat. <emphasis>If you have installed expat and do not use this switch, the
apache installation may overwrite some files from the expat installation.</emphasis></para>
<para><parameter>--enable-mods-shared=all</parameter>: We want modules
to be compiled and used as Dynamic Shared Objects
(<acronym>DSO</acronym>s) so they can be included and excluded from the
server using the run-time configuration directives.
</para>

<para><parameter>--enable-ssl</parameter>: Use this switch
to create the <filename class="libraryfile">mod_ssl</filename>
module and enable <acronym>SSL</acronym> support.</para>

<para>The main configuration file is called

server.</para>

<para>Install the <filename>/etc/rc.d/init.d/apache</filename>
init script included in the <xref linkend="intro-important-bootscripts"/> package.</para>
