How to install webDAV under Apache on Ubuntu (16.04)
HOW-TO DISCLAIMER: Most of the “how-to” posts are copy/pasted from a personal notes blog I keep for myself and as such sometimes presume familiarity with some of the concepts that might not be obvious. I’d like to make my notes and how-to’s more informative and accessible to a wider audience, so please let me know if something is not clear (or just plain wrong).
The first thing you must do is enable the necessary modules. Open a terminal window and issue the following commands:
sudo a2enmod dav sudo a2enmod dav_fs
Restart the Apache server with this command:
sudo systemctl restart apache2
Virtual host configuration
The next step is to create everything necessary for the virtual host. This will require creating specific directories (with specific permissions) and editing an Apache .conf file.
Let’s create the necessary directories. For simplicity, I’ll create a folder called webdav. From the terminal window, issue this command:
sudo mkdir -p /var/www/html/dav
Now we’ll change the owner of that directory to www-data with this command:
sudo chown www-data /var/www/html/dav
The next step is to create a .conf file that will help make apache aware of
the virtual host. For this, we’ll create a new
.conf file called
/etc/apache2/sites-available/webdav.conf. The contents of this file will be:
<VirtualHost *:80> ServerAdmin firstname.lastname@example.org ServerName webdav.planethawleywood.com DocumentRoot /var/www/html/dav/ <Directory /var/www/html/dav/> Options Indexes MultiViews AllowOverride None Order allow,deny allow from all DAV On AuthType Basic AuthName "webdav" AuthUserFile /var/www/html/dav/passwd.dav Require valid-user </Directory> </VirtualHost>
Save and close the file.
Now we enable the
webdav.conf file with:
sudo a2ensite webdav.conf
Before restarting apache, we need to create the WebDAV password file with this command (USER is a valid username on your system):
sudo htpasswd -c /var/www/html/dav/passwd.dav <user>
NOTE: if you need to update or recreate the users webDAV password, run the same
command with out the
-c option. (
-c creates a new entry)
When prompted enter the password for USER.
Next we must change the permissions of the newly created passwd.dav file so that only root and members of the www-data group have access to it. You’ll do so with the following commands:
sudo chown root:www-data /var/www/html/dav/passwd.dav sudo chmod 640 /var/www/html/dav/passwd.dav
Restart apache with this command:
sudo systemctl restart apache2
The WebDAV system is ready to test.
Testing your setup
There’s an easy to use tool for testing WebDAV—install the tool with this command:
sudo apt-get install cadaver
Once installed, issue this command (IP_OF_SERVER is the actual IP address of your server):
You should be prompted for a username/password. Enter the USER used when
setting up WebDAV and the associated password. If the cadaver command succeeds,
you’ll land at the
dav:/webdav/> prompt. Type
exit to exit cadaver.
Congratulations, WebDAV is working on your Ubuntu server. You can now use whatever tool you need (connect via file managers, web browsers, etc.) to connect to your WebDAV server.
