178 <para>
179 <parameter>--enable-mods-shared="all cgi"</parameter>: The modules should be
180 compiled and used as Dynamic Shared Objects (DSOs) so they can be included
181 and excluded from the server using the run-time configuration directives.
182 </para>
183
184 <para>
185 <parameter>--enable-mpm-shared=all</parameter>: This switch ensures that all
186 MPM (Multi Processing Modules) are built as Dynamic Shared Objects (DSOs),
187 so the user can choose which one to use at runtime.
188 </para>
189
190 <para>
191 <parameter>--enable-suexec</parameter>: This switch enables building of the
192 <application>Apache</application> suEXEC module which can be used to allow
193 users to run CGI and SSI scripts under user IDs different from the user ID
194 of the calling web server.

198 <parameter>--with-suexec-*</parameter>: These switches control suEXEC module
199 behavior, such as default document root, minimal UID that can be used to
200 run the script under the suEXEC. Please note that with minimal UID 100, you
201 can't run CGI or SSI scripts under suEXEC as the

206 <command>... /usr/lib/httpd/suexec</command>: These commands put
207 <command>suexec</command> wrapper into proper location, since it
208 is not meant to be run directly. They also adjust proper
209 permissions of the binary, making it setgid
210 <systemitem class="username">apache</systemitem>.

214 <command>chown -R apache:apache /srv/www</command>: By default, the

216 default icons, etc.) with the ownership of the user that extracted the
217 files from the tar file. If you want to change the ownership to another
218 user, you should do so at this point. The only requirement is that the
219 document directories need to be accessible by the <command>httpd</command>
220 process with (r-x) permissions and files need to be readable (r--) by the
221 <systemitem class="username">apache</systemitem> user.
