Prerequisites
To network your repository over HTTP, you basically need four components, available in two packages. You’ll need Apache httpd 2.0, the mod_dav DAV module that comes with it, Subversion, and the mod_dav_svn filesystem provider module distributed with Subversion. Once you have all of those components, the process of networking your repository is as simple as:
Getting httpd 2.0 up and running with the mod_dav module
Installing the mod_dav_svn backend to mod_dav, which uses Subversion’s libraries to access the repository
Configuring your httpd.conf file to export (or expose) the repository
You can accomplish the first two items either by compiling httpd and Subversion from source code or by installing prebuilt binary packages of them on your system. For the most up-to-date information on how to compile Subversion for use with the Apache HTTP Server, as well as how to compile and configure Apache itself for this purpose, see the INSTALL file in the top level of the Subversion source code tree.
