The Apache HTTP Server supports Dynamically Shared Objects
(DSOs), or modules, which can easily be loaded at
runtime as necessary.
The Apache Project provides complete DSO documentation online at https://httpd.apache.org/docs-2.0/dso.html.
Or, if the http-manual package is installed,
documentation about DSOs can be found online at https://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 Section 10.5.12 LoadModule for more
information.
If adding or deleting modules from http.conf,
Apache HTTP Server must be reloaded or restarted, as referred to in Section 10.4 Starting and Stopping 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 Apache documentation online at https://httpd.apache.org/docs-2.0/dso.html
as well as the apxs man page.
Once compiled, put the module in the
/usr/lib/httpd/modules/ directory. 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.
