1.3. Installing TYPO3 - Quick install

Quick Install

Note: Quick Install allows you to configure the vital database information for TYPO3 in three simple steps. It's meant for newbees and is automatically active if you download one of the zip-packages with complete sites. A “complete site” is a combination of the source-code and site-specific folders. Therefore this would not apply for the TYPO3 source-code archives but only such downloads as the testsite or other out-of-the-box TYPO3 applications.

Download testsite package from http://typo3.org/download/packages/
Upload the contents of this file to your webserver. Tip: The file contains thousands of files, so if you're able to unzip or untar the file on the server, better do that!
Hit the site with your browser and follow the Install Tool. The Install Tool will help you to 1) setup MySQL username/password/database, 2) dump any default database content and 3) check the configuration of your PHP-installation for compatibility. This is outlined below.
After the Install Tool, you should seriously consider to protect the folder typo3/install/ with a password or simply delete the ENABLE_INSTALL_TOOL file.

The Install Tool

The Install Tool is located in 'typo3/install/' but should automatically start in “123”-mode with password 'joh316' if you have not set up any database for the site.

In other words, this is what you should see:

1: Enter the username and password to your MySQL database:

2: Select the database (should be empty) or create a new by name:

Figure 3 Install Tool Step Two – Create or select database

3: If everything is OK, continue to installation of the default dataset:

4: If the database is empty (has zero tables), just click “import database” and the sql-file is dumped

5: The mandatory setup is completed, but please remember to change the password of the Install Tool or take another appropriate action towards securing the tool.

Please consider to go into normal-mode with the Install Tool in order to verify all the details of the configuration. Especially the image generation software must be paid attention to!

See details in the next section of this document.

Very Important: Changing Image Processing settings

Very Important:

When you change the settings for Image Processing (in normal mode) you must take into account that old images may still be in typo3temp/ folder and prevent new files from being generated! This is especially important to know, if you're trying to set up image processing for the very first time.

The problem is solved by clearing the typo3temp/ folder. Also make sure to clear the cache_pages table.
