11.2.2. Warnungen

Nachdem Sie Mahara installiert haben, sehen Sie als Site-Administrator einige Hinweise. Beachten Sie alle Hinweise und nehmen Sie erforderlichen Einstellungen vor, um sicherzustellen, dass Ihre Seite so sicher wie möglich ist.

Example of a warning on the Admin home page

1. Session entropy Länge: Ihre PHP session.entropy_Einstellung ist zu kurz. Setzen Sie sie in der php.ini mindestens auf 16, um sicher zu stellen, dass sichere Session IDs zufällig erzeugt werden nicht erratbar sind. Weitere Hinweise hierzu finden Sie im OWASP session management cheatsheet.

2. Noreply E-Mailadresse: Wenn die System-E-Mailadresse fehlt oder fehlerhaft eingegeben wurde, werden Sie aufgefordert die Werte zu prüfen und zu korrigieren. Sehen Sie nach unter System E-Mailadresseinstellungen.

3. Site-wide password salt: If you do not have one set, please edit your config.php file and set it to a reasonable length.

4. SAML setup: If you do not have SAML authentication set up properly and do not have SAML activated, you do not see any warning messages as they would only go away if you activate the plugin and install all the required dependencies.

11.2.3. Registration

Administration menu → Admin home → Register

As site administrator you can choose to register your Mahara site with mahara.org and help us compile a list of Mahara installations around the world to get a picture by how many people Mahara is used. Currently, this list is not published online. When you are on the administration overview page, you will see a link directly to the registration page.

11.2.3.1. Register your site

You can register your Mahara site at any point in time.

You can preview the data that would be sent on a weekly basis. All information is sent anonymously. We will only know, for example, which version of Mahara you are running, how many times blocks or artefacts have been used, how many users you have etc.

Registrieren Sie Ihre Mahara-Installation beim Mahara Projekt

1. Data included: Click this panel to preview the data that will be sent from your site.

2. Register with mahara.org: Set this switch to „Yes“ if you wish so send regular updates about your site to the project. These updates are based on changes in your site and include only anonymous updates once a week.

   Bemerkung

   This setting was renamed in Mahara 18.10 to make it clearer that the registration and sending of weekly data happens at the same time.

3. Click the Save button to finish your registration with the Mahara project or click Cancel to abort.

11.2.3.2. Revoke registration

You can decide not to send weekly anonymous updates about your site to Mahara at any point. If you revoke your registration, no more data will be sent.

Revoke the registration of your Mahara site with the Mahara project

1. Data included: Click this panel to preview the data that is currently being sent from your site.

2. Remain registered: Set this switch to „No“ if you no longer wish to send regular updates about your site to the project.

3. Click the Save button to finalize your change or click Cancel to abort.

11.2.4. Site-Informationen

Die Site-Informationen geben Ihnen als Site-Administrator einen Überlick über:

• Wie die Site genutzt wird.

• Wann die Site installiert wurde.

• Wie groß die Datenbank ist.

• Wie groß das Dateivolumem ist.

• Welche Version von Mahara genutzt wird.

• Ob der Cron-Job läuft oder nicht.

Site-Informationen

If you have problems with your Mahara instance and you request information from the community in the forums, this information, esp. about your version and the cron, are useful to have. Furthermore, the version number allows you to check that you have the latest security release of your Mahara version installed.

The cron job is very important in Mahara as a number of vital tasks are only performed when it is running. You can find more information of how to set it up on the wiki. If the cron is not running or only partially running, that information is displayed in red.

11.2.5. Clear caches

Administration menu → Admin home → Overview

A number of elements are cached in Mahara on the system level to speed up the site. In some cases, you may wish to force a new version though if the browser doesn’t recognize it on its own.

Clear all caches at once

Click the Clear caches button to clear all caches.

Bemerkung

The caches can also be cleared via a commandline script, which system administrators can find in /admin/cli/clear_caches.php.

11.2.6. Plattform sperren

Administration menu → Admin home → Overview

You may close the site to everyone except administrators. This is useful when you prepare for and complete a database upgrade. Only administrators will be able to log in during maintenance mode until you either reopen the site or an upgrade is successfully completed.

Mahara-Site schließen

Since the site is not accessible to anyone unless they are logged into the site as site administrator, certain processes would also fail, e.g. accessing the SAML metadata that is monitored by IdPs. It is possible to add a flag to a php file to ignore maintenance mode.
