Chapter 14. Apache HTTP Server

181

  LoadModule

lines for modules packaged in their own RPMs (

mod_ssl

,

php

,

mod_perl

, and the

like) are no longer necessary as they can be found in the relevant file in the

/etc/httpd/conf.d/

directory.

The various

HAVE_XXX

definitions are no longer defined.

14.2.1.4. Other Global Environment Changes

The following directives have been removed from Apache HTTP Server 2.0's configuration:

  ServerType

  The Apache HTTP Server can only be run as

ServerType standalone

making

this directive irrelevant.

  AccessConfig

and

ResourceConfig

  These directives have been removed since they mirror

the functionality of the

Include

directive. If you have

AccessConfig

and

ResourceConfig

directives set then you need to replace these with

Include

directives.

To ensure that the files are read in the order implied by the older directives the

Include

directives

should be placed at the end of

httpd.conf

, with the one corresponding to

ResourceConfig

preceding the one corresponding to

AccessConfig

. If you were making use of the default values

you will need to include them explicitly as

conf/srm.conf

and

conf/access.conf

.

14.2.2. Main Server Configuration

The main server configuration section of the configuration file sets up the main server, which responds

to any requests that are not handled by a

VirtualHost

definition. Values here also provide de 

t

u

faults for any

VirtualHost

containers you may define.

t

u

The directives used in this section have changed little between Apache HTTP Server 1.3 and version

2.0. If your main server configuration is heavily customized you may find it easier to modify your

existing configuration to suit Apache 2.0. Users with only lightly customized main server sections

should migrate their changes into the stock Apache 2.0 configuration.

14.2.2.1. UserDir Mapping

The

UserDir

directive is used to enable URLs such as

http://example.com/~jim/

to map to a

subdirectory within the home directory of the user

jim

, such as

/home/jim/public_html

. A side 

effect of this feature allows a potential attacker to determine whether a given username is present on

the system, so the default configuration for Apache HTTP Server 2.0 disables this directive.

To enable

UserDir

mapping, change the directive in

httpd.conf

from:

UserDir disable

to the following:

UserDir public_html
