Este capítulo ha sido escrito para todos aquellos que tengan la intención de instalar PrestaShop en su servidor web online.
Si desea instalar PrestaShop en su propio ordenador, deberá primero seguir las instrucciones de esta página: Installing PrestaShop on your computer.

Si ya ha leído las instrucciones de esa página, vaya directamente a la sección "Creación de una base de datos para su tienda" que encontrará en esta misma página.

Instalación de PrestaShop

PrestaShop es muy fácil de instalar. Una vez que todos los archivos estén subidos a su servidor web, debería poder empezar a configurar su tienda en menos de 5 minútos: el proceso de instalación es muy sencillo, ya que el instalador se encarga practicámente de todo el trabajo sin usted apenas tenga que intervenir. Los usuarios menos experimentados podrían necesitar entre 10 y 20 minutos para completar todo el proceso.

Antes de empezar, asegúrese de tener con todos los requisitos necesarios: webhost o espacio de alojamiento en un proveedor de hosting, nombre de dominio, cliente FTP, editor de texto. Asegúrese primeramente, de seguir las instrucciones de la página "Lo que necesita para empezar": http://doc.prestashop.com/display/PS16/Lo+que+necesita+para+empezar.

Algunos proveedores de hosting ofrecen la opción de instalar una aplicación de Prestashop autoinstalable con tan sólo un clic de ratón, ahorrándole tiempo para que pueda empezar a trabajar aún más rápido. El uso de este servicio puede reducir drásticamente el tiempo de instalación para los usuarios sin experiencia.

Estos proveedores de hosting utilizan principalmente las siguientes bibliotecas de scripts:

Algunos de estos scripts incluso soportan la actualización en un 1-clic, lo que tiene un valor incalculable.

Otros host o anfitriones, tienen sus propios scripts de instalación. Consulte con su proveedor de hosting para obtener más información. 

 Last but not least, PrestaShop has its own hosting solution: by registering on PrestaShop.com, you can create a 100% free PrestaShop Cloud store, and thus offload all the technical hurdles of hosting to our own team, and can focus on your shop, clients and sales.

Quick installation instructions

Here's the quick set of instructions for those who are already comfortable with installing PHP/MySQL applications on a web server. If the lack of details bothers you, you will find detailed instructions in the next section of this chapter.

  1. Download and unzip the PrestaShop package if you haven't already.
  2. Create a database for PrestaShop shop on your web server if it is possible. In case there is no MySQL user who has all privileges for accessing and modifying this database, create it as well.
  3. Upload the PrestaShop files and folders to the chosen location on your web server. Do not upload the root /prestashop folder directly: only the files and folders that it contains.
  4. Run the PrestaShop installation script by accessing the public URL for the chosen location in a web browser. This should be the URL where you uploaded the PrestaShop files.
  5. Follow the instructions on each screen of the installer.
  6. Once the installation is done, delete the /install folder and write down the new of the /admin folder, which has been generated in order to be unique to you, for security reasons.

PrestaShop should now be installed and ready to be configured! Continue to the First steps with PrestaShop 1.6 chapter of the User Guide.

Detailed instructions

Downloading and unzipping the PrestaShop archive

You can download the latest version of PrestaShop at http://www.prestashop.com/en/download.

You only have one download option: the latest stable version, ready for all kinds of online stores.

If you need to download any of the previous versions, go to this address: http://www.prestashop.com/en/developers-versions. Scroll down to the "Previously released versions" section.

Note that it is never recommended to use any other version than the current stable one.

Click on the "Download" button, and save the archive on your computer (such as on your Desktop). You should get a file named "prestashop_1.6.0.4.zip" (or an equivalent, depending on the version numbers).

The downloaded file is a Zip archive, meaning one file containing all of PrestaShop's files in compressed form. In order to continue with the process, you must uncompress the archive.

If your operating system does not natively support Zip files, you can download and install a dedicated tool, such as:

Using a Zip tool, extract the content of the archive to a known location on your hard-drive (such as on the Desktop again). Do not upload the Zip file directly to your web server.

The Zip archive has two items at its root :

  • The "prestashop" folder, which contains all the PrestaShop files that you will soon be uploading on your web server.
  • The "Install_PrestaShop.html" file, which opens this very page in your default browser.

The "Install_PrestaShop.html" must not be uploaded on your web server.

Uploading PrestaShop

You should now have a hosting space at your disposal (if not, read the "What you need to get started" chapter of this guide), and a folder on your hard-drive with the uncompressed PrestaShop archive.

This step makes you upload the PrestaShop files on your hosting space. This is done by connecting your computer to your server using a tool known as a "FTP client", which you should have installed while reading the "What you need to get started" chapter. We will be using the free FileZilla (http://filezilla-project.org/).

Connect to your hosting space using your FTP client, by using the connection details provided by your web host (if not, contact your host). Once connected, it is time to transfer the PrestaShop files from your computer to your server.

In FileZilla (or any other FTP client), browse your local folders until you find the one that contains the PrestaShop files. Keep it open in the "Local site" section on the left.

In the "Remote site" section (on the right), browse to the location where you want PrestaShop to be publicly available (root of the domain, sub-folder, sub-domain...). This can change a lot, depending on both your host and your needs:

On FileZilla's left side, you should now have the local folder where you keep the PrestaShop files from the Zip archive, and on the right side, the destination location. If you haven't done it yet, uploading is simple: select all files and folders from the local folder (use Ctrl-A), and either drag & drop them to the remote folder, or right-click on the selection and choose "Upload" in the context menu.

Uploading can take several minutes, as PrestaShop uses more than 7500 files and almost 1000 folders. After a while, all of PrestaShop's files and folders should be online. Great!

Creating a database for your shop

Before you can actually install PrestaShop, you need to make sure your MySQL server has a database ready for PrestaShop's data. If not, you must create one.

Creating a database can be done using any database administration tool. We will be using the free phpMyAdmin tool (http://www.phpmyadmin.net/), which should come pre-installed on most web hosting.

Some hosts prefer to have customers use a graphic control panel, such as cPanel, Plesk or a custom-made one. Make sure you read your host's documentation about handling MySQL databases, and create a database for your shop by following their specific explanations.

Connect to phpMyAdmin using your account credentials, which your host provided you with. It should be accessible through a standard URL, tied to your domain name, or host's domain name.

In the left column, you can see the databases currently available on your MySQL server. Some of them should be left alone, because they are either used by phpMyAdmin or by the host: phpmyadmin, mysql, information_schema, performance_schema and others. Read your host's documentation to know if one of these can be used as a default database.

Either way, you can create a brand new database by going in the "Database" tab and using the central form named "Create new database". Simply enter a unique name, and click "Create". The name of the database will be added to the list on the left. You can now use it to store PrestaShop's data.

Launching the auto-installer

Now comes the part where it all comes together: installing PrestaShop.

The installation process is quite easy, as it is streamlined by PrestaShop's auto-installer. You should be able to browse through it in handful of minutes. Do read each page thoroughly so as to not miss any information.

To launch the installer, simply browse to PrestaShop's location on your web server: the script will automatically detect that PrestaShop is not yet installed, and will take you to the auto-installer.
You can also directly type the address of the /install folder: http://www.example.com/prestashop_folder/install.

If you are making an installation on your own computer, this installation should be done in the PrestaShop folder on your local web server, which should be available at http://127.0.0.1/prestashop.

From there on, you just have to read, click, and fill a few forms.

There are 6 steps. At the top of the page, the installation assistant gives you a visualization of where you are in the process: the gray faces turn into smiling faces after each step that is completed.

Step 1: Welcome page

This page is a quick intro into the installation process. You can choose the language in which the installer will display its instructions.

You also get a link to the documentation site (http://doc.prestashop.com/), and the PrestaShop support phone number. You can learn more about our support service by going to http://support.prestashop.com/en/.

Select the language in which you wish the installer to be, then click the "Next" button. This will also set the default language for your PrestaShop installation – but other languages will also be available for you to enable.

Step 2: PrestaShop's licenses

This second page is a simple requirement: PrestaShop is free and distributed under a certain set of open-source licenses. You simply cannot use this software if you disagree with the terms of the licenses, and this step requires you to explicitly acknowledge them.

Read PrestaShop's licenses:

You must agree to both licenses in order to install PrestaShop.

To access the next step, you must check the "I agree to the above terms and conditions" box, then click "Next". If you do not explicitly agree to the licenses, you cannot install PrestaShop: the "Next" button will not even be clickable.

Step 3 & 4: System compatibility & Store information

The third page makes a quick check of all the server parameters on your host. In most cases, you will not see this page, because if nothing wrong is found, you are taken directly to the fourth page, "Store information". If so, you can still go have a look at the third page by clicking on the "System compatibility" link in the left sidebar.

If something does go wrong during the server check that happens in the third step, the installer displays the "System compatibility" page, where you can see all the checks that failed.

System compatibility

This page checks that everything is OK with your server configuration: PHP settings, permissions on files and folders, third-party tools, etc.

If anything goes wrong, the installer stops you here, enabling you to see the few technical details that need fixing, be it changing the PHP configuration or updating the file permissions.

Here is a list of the checks that are performed during this third step:

CheckHow/where to fix it?
Is PHP 5.1.2 or later installed?Web server
Can PrestaShop upload files?php.ini file (file_uploads)

Is the PDO MySQL extension loaded?php.ini file (extension=php_pdo_mysql.so)

While changing the PHP configuration can only be done on a case-by-case basis depending on your level of access to your server, and therefore can only be explained in full details, updating the file permissions is easier to explain.

Permissions are the way a filesystem grants access rights to specific users or user groups, controlling their ability to view or make changes to files and folders. The installer needs to make several changes to the files that you uploaded, and if the filesystem does not allow for these changes through proper permissions, then the installer cannot complete its process.

Hence, if the installer shows that some files or folders do not have proper permission, you have to changer these permissions yourself. This will require you to access your files on your web server, and therefore use your FTP client (such as FileZilla) or the command line.

Log-in to your server account using your FTP client, browse to PrestaShop's folder, and find the folders that are marked by the installer as in need of a permission change.

Changing file/folder permission on a Unix/Linux system is called a "CHMOD", after the command of the same name (see: http://en.wikipedia.org/wiki/Chmod – you can find an explanation of file permissions here: http://www.elated.com/articles/understanding-permissions/).
Giving files or folders a "write permission" is called "doing a CHMOD 755" or "a CHMOD 775", depending on the host.

Some hosts might require you to use CHMOD 777, although it is not recommended for anything more than a one-time need.
If you have to use CHMOD 777 in order to install PrestaShop, make sure to switch to a safer setting (for instance, 775 for folders and 664 for files) once you are done installing.
Read your host's documentation carefully.

Thanks to FileZilla (and most FTP clients), you do not have to use any Unix command. Most FTP clients make it possible to change permissions easily and graphically: once you have found a file or folder that needs such a change, right-click on it, and in the context menu choose "File permissions...". It will open a small window.

Depending on your server configuration (which you don't always have a hand at), you will need to check both the "Read" and "Execute" columns of boxes, and at least the "Owner" and "Group" rows for the "Write" column. Some hosts might require you to have the public "Write" box checked, but be careful with that: it is rarely a good thing to have anyone on your server be able to edit the content of your PrestaShop installation.

Some folders might need to have all their files and sub-folders change permissions too. In that case, check the "Recurse into subdirectories" box.

While changing permissions in your FTP client, you should regularly check that you have made the correct changes by running the installer's compatibility checks again: click the installer's "Refresh these settings" button as often as necessary.
Once all indicators are green, you can click "Next". If you cannot have them all green, at least make sure the installer displays the "PrestaShop compatibility with your system environment has been verified!" message at the top of the page.

System information

This is where you can start customizing your shop: give it a name and a logo, indicate its main activity, and indicate the personal information for the shop owner (which has legal binding in most countries)...

Do not use a colon in your store's name, as it might prevent some feature from working (for instance, e-mail sending might fail).

You can replace the colon with a dash if you need to have two sections in the title. For instance, use "MyStore – The best place for items to buy" instead of "MyStore: The best place for items to buy".

Concerning the logo, you should note that it will appear:

Therefore, do not keep the default PrestaShop logo, for obvious reasons.

Click "Next" to continue.

Step 5: System configuration

This page contains a form that enables you to tell PrestaShop where the database server is, and which database it should use, along with a few other details. All this information should have been provided to you by your web host.

Fill all the fields with the database connection information provided by your web-host:

Click the "Test your database connection now!" button in order to check that you did use the correct server information.

Click "Next": the install will start configuring your shop, creating and populating the database tables, etc. This might take a few minutes: please be patient and do not touch your browser!

The installer does the following:

Once it is done, your shop is installed and ready to be configured!

Completing the installation

As you can read right on the final page of the installation process, there are a couple of last actions to perform before you can leave the installer.

An easy way to improve your installation's security is to delete some key files and folders. This is done using your FTP client, directly on the server. The items to delete are:

Click on the "Manage your store" button in order to be taken to your administration area.

Another way to secure your installation is to use a custom name for the administration folder: change the "admin" folder for something unique to you, such as "4dmin-1537" or "MySecReT4dm1n".
Write down the new name for your new "admin" folder
, because from now on you will access your administration pages using this address!

Finally, in order to close all potentially malicious doors, use your FTP client to update the files and folders permissions to 664, or 666 if your host requires it. If it turns out low access rights prevent some modules to work, you should set permissions back to 755.

Congratulations! Installation is now complete.

Log in to the PrestaShop back office by going to your newly-renamed "admin" folder, and start filling your catalog with products, adding carriers and shipping costs, adding manufacturers and suppliers, changing the theme, and generally configuring the many settings to suit your tastes and needs. See the user guide's "First steps with PrestaShop 1.6" chapter for more information: http://doc.prestashop.com/display/PS16/First+steps+with+PrestaShop+1.6.

You should regularly back up your database and files, ideally on more than one computer, in case of problems related to hardware or security.
