Disable the Web interface for add-on installation
Before running the commands shown on this page, you should load the Bitnami stack environment by executing the installdir/use_APPNAME script (Linux and MacOS) or by clicking the shortcut in the Start Menu under “Start -> Bitnami APPNAME Stack -> Application console” (Windows). On OS X VMs, the installation directory is /opt/bitnami and OS X VM users can click the “Open Terminal” button to run commands. Learn more about the Bitnami stack environment and about OS X VMs.
To hide this option from the admin web interface, edit the configuration file at installdir/apps/moodle/htdocs/config.php and set:
$CFG->disableonclickaddoninstall = true;
On Linux systems, also remove the write permissions from the web server group in the Moodle directories:
$ find installdir/apps/moodle/htdocs/ -type d 755
