J3.x:Installing Joomla/fr

Installer Joomla! pour la première fois est très simple. L'installateur web natif de Joomla! rend la configuration de votre nouveau site aussi simple qu'un jeu d'enfants.

Configuration requise

Exigences D'Hébergement

Avant de commencer l'installation de Joomla!, voici quelques prérequis à remplir pour installer avec succès Joomla! 3.x. Ceux-ci s'appliquent que vous ayez un serveur dédié, un hébergement mutualisé, ou que vous installiez une copie sur votre serveur local à fin de test ou développement.

Vous devez respecter les exigences suivantes pour installer et utiliser Joomla! 3.x

Préparation de l'Installation

Vous devrez accomplir deux tâches avant de pouvoir installer Joomla! sur votre serveur. Tout d'abord, vous aurez besoin de télécharger le paquet de fichiers Joomla!. Ensuite, vous aurez besoin d'avoir une base de données que Joomla! utilisera.

Télécharger et Charger le Paquet de Fichiers Joomla!

1. Télécharger la version actuelle de Joomla! 3.x
2. Déplacer le paquet d'installation de Joomla! que vous venez de télécharger sur le serveur. Utiliser un Client FTP pour transférer les fichiers Joomla! 3.x sur votre serveur. Si vous n'avez pas encore de logiciel FTP, nous vous recommandons Filezilla

Aide - Ceci peut être accompli en déplaçant simplement le paquet téléchargé sur votre serveur, puis en le décompressant. Sinon, vous pouvez décompresser les fichiers sur votre ordinateur local, puis déplacez l'installation Joomla sur votre serveur. Quoi qu'il en soit, l'installation de Joomla doit être décompressée à la racine de votre site.

Attention !

La Base de Données pour l'Installation de Joomla!

1. If you need to create a database, please read "Create a database for use with Joomla!" first or skip to step #2.
2. You will need to note basic database information needed when the actual Joomla! installation is started.
   • Location of datase, localhost? Or a specific host's server such as dbserver1.yourhost.com
   • The database name
   • The database user's name
   • The database user's password

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.
• Description: Enter a description of the website. This is a the global fallback meta description used on every page which will be used by search engines. Generally, a maximum of 20 to 25 words is optimal. Again, this can be changed on the Site Global Configuration page at any time. For more on metadata, see Global Metadata Settings and Entering search engine meta-data.
• 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.
• 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.
• Site Offline: Click the Yes or No box. Yes - this means when installation is complete, your Joomla! website will display the 'Site is offline message' when you browse to yoursitename.com to view the home page. No - this means the site is live when you browse to yoursitename.com to view the home page. You can use the Site Global Configuration in the Administration interface to change the Offline status at any time.

When everything on the first page is completed, click the next 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 intructions 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.
• Old Database Process: Should the installer backup or delete existing tables during the installation of new tables? Click, Yes or No to select the choice.

All these choices 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.

When all the information has been filled in, click the next button to proceed:

Finalise

Overview

It is now time to finalise the Joomla! installation. The last page of the web browser installation contains all the information about the installation. This includes the options(at the top) for installing sample data and the installation's configurations(at the bottom).

Install Sample Data and Email Configurations

The first options are for automatically installing sample content to the website and emailing the configuration settings.

If you are new to Joomla! it would be benefical to install some sample data to see how Joomla! works. You can at this time choose to have the configuration settings emailed to you. If the Email Configuration choice is selected, the Email Password choice will appear. The email password is off by default for security. You can choose to have the password included, just click Yes.

Time to check the configurations of your install and the environment of the installation.

Configuration Check

Checking Your Configurations

If everything is in order, you will see the install at the top of the overview page. If not, this is the place to check and see what may be causing an issue.

The section is broken into 4 groups:

• Main Configuration: All the website specific information, such as the website name, description, admin username, etc.
• Database Configuration: Contains the information about the database Joomla! will use.
• Pre-Installation Check: These requirements must all be shown as Yes, otherwise you will not be able to install Joomla! With the exception of the PHP Version, the rest are usually controlled in the php.ini. You may need assistance from your host in correcting these settings or checking to see if it is possible to adjust them. For more information, see PHP configuration file file.
• Recommended Settings: These are settings are recommended in your PHP configuration, but will not prevent Joomla! from being installed. You can refer to the above instructions on how they may be changed.

If everything is correct and all checks are passed, you may now click the Install button in the top right corner of the Overview page. This will start the actual installation process.

After you click the Install button, you should see a progress bar with additional information of the installation. Once the installation completes, you should see the success page!

Finishing Up

Success and Finishing Up the Installation

Congratulations! Joomla! 3 is now installed, but there is one last step to complete the installation and start using your Joomla! powered site. You must delete the Installation Folder. Click on Remove Installation folder and a success message will appear. Now you can navigate to the Administrator log in by clicking Administrator or go right to your site by clicking Site.
