Recently I migrated a Prestashop website to AWS/EC2 and the process is quite smooth. Here’s how to do it.

1. Get your Website data: including Prestashop website files and a latest database dump. Remove all the files except index.php in /cache/smarty/compile and /cache/smarty/cache. (See here.)

2. Launch your EC2 instance. But before doing that, check first if a pre-configured or managed Prestashop is available in your preferred region (more info here). If not, choose the appropriate instance type and get it running. In my case I chose Ubuntu Linux.

3. Install the AMP (Apache, MySQL and PHP). On Ubuntu you can simply do it with a few simple commands:

sudo apt-get update
sudo apt-get upgrade
sudo tasksel install lamp-server
sudo apt-get install phpmyadmin

Make sure that you remember your password for MySQL root user and phpmyadmin user.

4. Copy your database dump and website files to your EC2 instance using scp, for instance:

scp -i you-key.pem files.tar.gz ubuntu@your-ec2-instance.compute.amazonaws.com

5. Create a MySQL user for Prestashop, you don’t want to use the root user for this purpose. You can do this using phpmyadmin or a command line. Also, create a database for Prestashop and grant the user you’ve created just now all privileges on this database.

6. Import your database from the dump:

mysql -u root -p ps < db_dump.sql

7. Extract your website files on your EC2 instance. In my case, inside /var/www/html/. If there is an index.html file inside this directory, remove it first. Make sure you set the correct user and group to all the website files:

sudo chown -R www-data:www-data *
sudo chmod -R 755 *

Note that if don’t set the correct permissions, you may get complaints from Apache, like the following:

PHP Fatal error:  Uncaught exception ‘SmartyException’ with message ‘unable to write file /var/www/html/cache/smarty/compile/46/d9/69/wrt54ecd6c1856a72.61943173’ in /var/www/html/tools/smarty/sysplugins/smarty_internal_write_file.php:44

8. Enable mcrypt for PHP:

sudo updatedb
locate mcrypt.ini
> /etc/php5/mods-available/mcrypt.ini
locate mcrypt.so
> /usr/lib/libmcrypt.so.4
> /usr/lib/libmcrypt.so.4.4.8
> /usr/lib/php5/20121212/mcrypt.so
sudo vi /etc/php5/mods-available/mcrypt.ini
sudo php5enmod mcrypt
ls -al /etc/php5/cli/conf.d/20-mcrypt.ini
> lrwxrwxrwx 1 root root 31 Feb 24 19:32 /etc/php5/cli/conf.d/20-mcrypt.ini -> ../../mods-available/mcrypt.ini
ls -al /etc/php5/apache2/conf.d/20-mcrypt.ini
> lrwxrwxrwx 1 root root 31 Feb 24 19:32 /etc/php5/apache2/conf.d/20-mcrypt.ini -> ../../mods-available/mcrypt.ini
service apache2 restart

9. Update your Prestashop settings in the config/settings.inc.php file. Set the correct database information.

10. Enable mod_rewrite:

sudo a2enmod rewrite
sudo service apache2 restart

Also, make sure to add something like the following in your apache site configuration file:

        <Directory />
                Options FollowSymLinks
                AllowOverride all
        </Directory>
        <Directory /var/www/html/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride all
                Order allow,deny
                allow from all
        </Directory>

And then remember to restart your apache server.

11. Install sendmail:

sudo apt-get install sendmail

12. Go to your Prestashop back office and reconfigure your domain. Go to Preferences -> SEO & URLs and scroll down to Set shop URL section.

Now everything should be OK, your new Prestashop website is available on your new domain!
