|
|
|
+ <p class="information">The following steps explain how to setup a webdav for Jtalk with Debian, but the setup on OSX and other Linux distros should be similar.</p>
|
|
|
+ <h4>Installing Apache and enabling the dav module</h4>
|
|
|
+ <p>Evaluate the following as root:</p>
|
|
|
+ <pre>~# apt-get install apache2
|
|
|
+~# a2enmod dav
|
|
|
+~# a2enmod dav_fs</pre>
|
|
|
+
|
|
|
+ <h4>Creating a password for the webdav</h4>
|
|
|
+ <pre>htpasswd -c /etc/apache2/htpasswd-webdav USERNAME</pre>
|
|
|
+
|
|
|
+ <h4>Setting up the webdav directory</h4>
|
|
|
+ <p>Add the following lines to the default vhost (in /etc/apache2/sites-available/default):</p>
|
|
|
+ <pre>Alias /jtalk/ "/path/to/jtalk/"
|
|

|
|
|
+ <p>Make sure the group www-data has required rights to modify files in the webdav directory.</p>
|
|
|
+
|
|
|
+ <h4>Restarting Apache</h4>
|
|
|
+
|
|
|
+ <p>To restart Apache, evaluate the following: <pre>~# /etc/init.d/apache2 restart</pre> and go to <code>http://localhost/jtalk/</code>.</p>
|
|
|
+ <p>The class browser should now be able to commit changes to disk.</p>
