mkdir /tmp/apache-php-session
chown apache:apache /tmp/apache-php-session
/etc/init.d/apache2 stop
/etc/init.d/apache2 start

# dthornton Disable reading by anonymous users
$wgGroupPermissions['*']['read'] = false;

# dathornton , restrict editing to only logged in users.
$wgGroupPermissions['*']['edit'] = false;

# Anonymous users can't create pages
$wgGroupPermissions['*']['createpage'] = false;

# Prevent new user registrations except by sysops
$wgGroupPermissions['*']['createaccount'] = false;
