module using the LoadModule directive. This directive must precede any other Subversion-related configuration items. If your Apache was installed using the default layout, your mod_dav_svn module should have been installed in the modules subdirectory of the Apache install location (often /usr/local/apache2). The LoadModule directive has a simple syntax, mapping a named module to the location of a shared library on disk: LoadModule dav_svn_module

modules/mod_dav_svn.so

Note that if mod_dav was compiled as a shared object (instead of statically linked directly to the httpd binary), you'll need a similar LoadModule statement for it, too. Be sure that it comes before the mod_dav_svn line: LoadModule dav_module LoadModule dav_svn_module

modules/mod_dav.so modules/mod_dav_svn.so

At a later location in your configuration file, you now need to tell Apache where you keep your Subversion repository (or repositories). The Location directive has an XML-like notation, starting with an opening tag, and ending with a closing tag, with various other configuration directives in the middle. The purpose of the Location directive is to instruct Apache to do something special when handling requests that are directed at a given URL or one of its children. In the case of Subversion, you want Apache to simply hand off support for URLs that point at versioned resources to the DAV layer. You can instruct Apache to delegate the handling of all URLs whose path portions (the part of the URL that follows the server's name and the optional port number) begin with /repos/ to a DAV provider whose repository is located at /absolute/path/to/repository using the following httpd.conf syntax: <Location /repos> DAV svn SVNPath /absolute/path/to/repository </Location> If you plan to support multiple Subversion repositories that will reside in the same parent directory on your local disk, you can use an alternative directive, the SVNParentPath directive, to indicate that common parent directory. For example, if you know you will be creating multiple Subversion repositories in a directory /usr/local/svn that would be accessed via URLs like http://my.server.com/svn/repos1, http://my.server.com/svn/repos2, and so on, you could use the httpd.conf configuration syntax in the following example: <Location /svn> DAV svn # any "/svn/foo" URL will map to a repository /usr/local/svn/foo SVNParentPath /usr/local/svn </Location> Using the previous syntax, Apache will delegate the handling of all URLs whose path portions begin with /svn/ to the Subversion DAV provider, which will then assume that any items in the directory specified by the SVNParentPath directive are actually Subversion repositories. This is a particularly convenient syntax in that, unlike the use of the SVNPath directive, you don't have to restart Apache in order to create and network new repositories. Be sure that when you define your new Location, it doesn't overlap with other exported Loc152
