Empfohlene Einstellungen in der PHP.ini

Es gibt einige PHP Einstellungen, die für die Installation von Joomla erforderlich sind. Die Einstellungen sind für gewöhnlich in der "php.ini" oder in der "user.ini" zu finden. Wenn es nötig ist, sprich mit deinem Hoster über Änderungen dieser Einstellungen. Arbeitest du an einem lokalen Host wie XAMPP solltest du durch diese Einstellungen nicht eingeschränkt sein, genauso wenig wie bei der Verwendung eines VPS (Virtual Private Server) oder bei dezidiertem Hosting.

Die nachfolgenden Werte für die PHP.ini sind lediglich empfohlene Werte.

• memory_limit - Minimum: 64M Empfohlen: 128M oder besser
• upload_max_filesize - Minimum: 20M
• post_max_size - Minimum: 20M
• max_execution_time - Empfohlen: 30

Vorbereitungen zur Installation

Vor der Installation von Joomla! auf deinem Server musst du zwei Aufgaben erfüllen. Als Erstes musst du die Joomla! Paketdateien herunterladen. Als Nächstes braucht man eine Datenbank zur Nutzung von Joomla!

Download und Upload der Joomla! Installationsdateien

Warnung!

1. Download der aktuellsten (nightly) Version von Joomla! 4.x
2. Verschiebe das heruntergeladene Joomla! Installationspaket auf den Server. Verwende einen FTP Client, um die Joomla! 4.x Dateien auf deinen Server zu übertragen. Es gibt mehrere mögliche Programme, hier ist eine detaillierte Liste von FTP Clients. Achte bitte darauf, dass du die offiziellen Versionen eines FTP-Clients verwendest.

Tipp – Dies kann durch einfaches Verschieben des heruntergeladenen Pakets auf deinen Server und anschließendes Entpacken erreicht werden. Alternativ kann man die Dateien auf dem lokalen Computer entpacken und dann die Joomla-Installation auf den Server verschieben. In beiden Fällen muss die Joomla-Installation im Root-Verzeichnis der Website erstellt werden.

Das Stammverzeichnis (root) des Servers

Warnung!

Datenbank für die Joomla!-Installation

1. Wenn Sie eine Datenbank erstellen müssen, lies bitte zuerst "Create a database for use with Joomla!" oder beginne mit Schritt #2.

Start Install

Main Configuration

With the above requirements met, a database created and the required Joomla! files in place, you are ready to install Joomla!. Start the Joomla! web installer by opening your favorite browser and browsing to the site's domain name. On host installation you will use http://www.yoursitename.com. If your are installing Joomla! locally, you will use http://localhost/<path to Joomla files>, and you should see the installation screen.

Joomla! will try to identify the Select Language field automatically from your browser's language. You can change this if needed.

Fill in the following information.

• Site Name: the name of your website — this can be changed at any point later in the Site Global Configuration page.

When everything on the first page is completed, click the Setup Login Data button to proceed:

Login Data

You should now see the login data screen.

Fill in the following information.

• Admin Name: the name of the admin. This how Joomla will greet you when you log in!
• Admin Username: Joomla! uses a default "admin" as the username for the Super User. You can leave it as is, change it now (which a good Security measure) or use My Profile in the Administration interface to change it later.
• Admin Password: remember that super user has maximum control of the site (frontend & backend), so try to use a difficult password. Use My Profile in the Administration interface to change it later. Confirm the password in the Confirm Admin Password box.
• Admin Email Address: the admin email address. Enter a valid email in case you forget your password. This is the email address where you'll receive a link to change the admin password.

When everything on the second page is completed, click the Setup Database Connection button to proceed:

Database Configuration

Configuration Settings

You will need to enter the information about the database you will use for Joomla! now. It was suggested to write this information down under "Prepare for Install" tab. You may also read or review Creating a Database for Joomla!.

For simplification, these instructions are a reference to installing with a MySQLi database. The instructions on the installation page are self explanatory, but here they are again:

• Database Type: MySQLi is the common database used
• Hostname Where is your database located? Common is localhost, but some hosts use a specific database server such as dbserver1.yourhost.com
• Username: the username used to connect to the database
• Password: the password for the database's username
• Database Name: the name of the database
• Table Prefix: one is generated automatically, but you can change it. For example, jos3_ can be used. Just don't forget to put the underscore character (_) at the end of the prefix.
• Connection Encryption: specifies how the connection to the database should be encrypted. If you don't know - then it's best to stick to the default. However this allows enterprises who two way SSL encryption to the database to provide it.

All these choices and more can be edited on the Site Global Configuration page, under Server options after the installation is completed. Note, you will break your installation if you change these settings after installation unless you have a complete copy of the current database being used by the Joomla! installation. Common uses would be to update the username and password of the database or to complete a move of an existing installation to a new host with different parameters.

After you click the Install Joomla button, you should see the Joomla logo spinning. Once the installation completes, you should see the success page!

Finishing Up

• Language packs included in custom distributions will not be listed at this stage as they are already installed.
• A version of the packs proposed will match the Joomla Major version (4.0.x, 4.1.x, etc.). The minor version of the pack may not correspond, e.g. you are installing version 4.0.3 and a 4.0.2 language pack is shown.
• Unmatched language packs in the above example may have untranslated strings.
• The unmatched language packs will be offered as an update when the packs are updated by the registered Translation teams. The available update will be shown in the Control panel as well as in Extensions Manager → Update. This behavior is similar to Extensions Manager → Install Languages.

Click Next and a progress bar will be display while the language pack or packs are downloaded.
