# Last installation settings

Once Chamilo is installed, the success message also brings a short warning message

« **Security hint**: To protect your site, please change permissions on main/inc/conf/configuration.php and main/install/index.php (not their directories) to read-only (CHMOD 444). »

*Illustration: Installation – Installation report*

It is preferable, in fact, to remove the *main/install/* directory completely (the confirmation text is not really accurate about this):

user\@server:/var/www/chamilo$ sudo rm -rf main/install/

This will prevent anybody (except the *root* user) to see this directory, and thus to use it.

For the *configuration.php* file, **0444** are the appropriate permissions to assign:

user\@server:/var/www/chamilo/$ cd main/inc/conf/

user\@server:/var/www/chamilo/main/inc/conf$ sudo chmod 0444 configuration.php

When this operation is completed, using Chamilo can begin safely clicking on the *Go to the newly created portal* link.
