<para><option>--with-expat=/usr</option>: Uses system installed
|
|
<application>expat</application>. <emphasis>If you have installed
|
|
<application>expat</application> and do not use this switch, the
|
|
<application>Apache</application> installation may overwrite some files from
|
|
the <application>expat</application> installation.</emphasis></para>
|
|
|
|
<para><parameter>--enable-mods-shared=all</parameter>: The modules should 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><option>--enable-ssl</option>: Use this switch
|
|
to create the <filename class="libraryfile">mod_ssl</filename>
|
|
module and enable <acronym>SSL</acronym> support.</para>
|
|
|
|
<para><command>chown root:root ...</command>: This command changes
|
|
the ownership of some installed files, the result of building the package as a
|
|
user other than root.</para>
|
|
|
|
<para><command>chown -R apache:apache /srv/www</command>: By default, the
|
|
installation process installs files (documentation, error messages, default
|
|
icons, etc.) with the ownership of the user that extracted the files from the
|
|
tar file. If you want to change the ownership to another user, you should do
|
|
so at this point. The only requirement is that the document directories need
|
|
to be accessable by the <command>httpd</command> process with (r-x) permissions
|
|
and files need to be readable (r--) by the apache user.</para>
