Adding Modules

22.6. Adding Modules
The Apache HTTP Server is distributed with a number of modules. More information about Apache
HTTP modules can be found on http://httpd.apache.org/docs/2.2/mod/.
The Apache HTTP Server supports Dynamically Shared Objects (DSOs), or modules, which can
easily be loaded at runtime as necessary.
http://httpd.apache.org/docs/2.2/
The Apache Project provides complete DSO documentation online at
dso.html. Or, if the http-manual package is installed, documentation about DSOs can be found
online at http://localhost/manual/mod/.
For the Apache HTTP Server to use a DSO, it must be specified in a LoadModule directive within
/etc/httpd/conf/httpd.conf. If the module is provided by a separate package, the line must
appear within the modules configuration file in the /etc/httpd/conf.d/ directory. Refer to
LoadModule
for more information.
If adding or deleting modules from http.conf, Apache HTTP Server must be reloaded or restarted,
Section 22.3, "Starting and Stopping
as referred to in
httpd".
If creating a new module, first install the httpd-devel package which contains the include files,
the header files, as well as the APache eXtenSion (/usr/sbin/apxs) application, which uses the
include files and the header files to compile DSOs.
After writing a module, use /usr/sbin/apxs to compile the module sources outside the Apache
source tree. For more information about using the /usr/sbin/apxs command, refer to the the
http://httpd.apache.org/docs/2.2/dso.html
Apache documentation online at as well as the apxs man
page.
Once compiled, put the module in the /usr/lib/httpd/modules/ directory. For RHEL platforms
using default-64-bit userspace (x86_64, ia64, ?) this path will be /usr/lib64/httpd/modules/.
Then add a LoadModule line to the httpd.conf, using the following structure:
LoadModule <module-name> <path/to/module.so>
Where <module-name> is the name of the module and <path/to/module.so> is the path to the
DSO.

22.7. Virtual Hosts

The Apache HTTP Server's built in virtual hosting allows the server to provide different information
based on which IP address, hostname, or port is being requested. A complete guide to using virtual
hosts is available online at http://httpd.apache.org/docs/2.2/vhosts/.

22.7.1. Setting Up Virtual Hosts

To create a name-based virtual host, it is best to use the virtual host container provided in
httpd.conf as an example.
The virtual host example read as follows:
#NameVirtualHost *:80
#
#<VirtualHost *:80>
