I am about to set up a webdav server under CentOS 6.0
Here are some web sources:
-http://www.cyberciti.biz/faq/rhel-fedora-linux-apache-enable-webdav/
-http://www.stigmatedbrain.net/drupal/?q=node/69

• To set Id property (ps is short for propset) and list results:

svn ps svn:keywords Id [file(s)]
svn ps svn:executable yes [file(s)]
svn pl -v [file(s)]

This article was originally posted at:
http://labs.redbd.net/blog/index.cfm/2006/7/5/Website-Releases-via-Subversion-SVN
but this site now seems to be dead, so I have recovered it from archive.org and re-posted it.

If I am breaking any copyrights here, please let me know and I will remove it.

Note that Drupal now blocks any path containing "svn-base". See: http://drupal.org/node/28776

#place to put dget scripts

DGETDIR=/root/dget

#get dget suite and install it, editing settings.sh if necessary

svn co http://drupal-get.svn.sourceforge.net/svnroot/drupal-get/trunk $DGETDIR
cp $DGETDIR/rename_to_settings.sh $DGETDIR/settings.sh
$DGETDIR/setup.sh $DGETDIR

#check out drupal core, contrib

dsvn checkout

#use dsite checkout if no need to commit from this site
#and optionally, the Acquia distribution (ignore any warning at the end)

dsvn checkout x x a6paths

Putting this code into a page will let it update the site from a repository:

<pre>
<?php system( 'svn up sites/default/...'); ?>
</pre><h1>Done!</h1>

Note that apache must have write permission for the whole directory tree.
I tried the following but couldn't get it to work (probably not in my version of PHP):
svn_checkout('http://myserver.com/svn/demo', '/var/www/html/demo/temp');

If the repository requires a password for update, the following can be done:


yum install subversion mod_dav_svn
mkdir -p /var/www/svn/test #place to keep repository
svnadmin create --fs-type fsfs /var/www/svn/test #make a test one
chown -R apache.apache /var/www/svn
vim /etc/httpd/conf/httpd.conf #make sure the following two lines are there
LoadModule dav_svn_module modules/mod_dav_svn.so
LoadModule authz_svn_module modules/mod_authz_svn.so
#
vim /etc/httpd/conf.d/subversion.conf #and add the following

<Location /svn>
   DAV svn
   SVNParentPath /var/www/svn
   # Limit write permission to list of valid users.
