How to setup High Availability PrestaShop on multiple servers with MariaDB Galera Cluster

November 7, 2014 By Severalnines

PrestaShop is a popular open source e-commerce software powering over 200,000 online stores, according to the company. We’ve seen a bit of interest into high availability PrestaShop setups, so this post will show you how to achieve that on multiple servers. Note that this setup not only caters for failures, but by load balancing traffic across multiple servers, it also allows the system to scale and handle more users.

This post is similar to our previous posts on web application scalability and high availability:

[PrestaShop] Carrier selection by postal code

To select the carrier / delivery method in PrestaShop by the postal code of the delivery address, create a file Address.php in /override/classes with this content:

class Address extends AddressCore
    protected static function getPostcodeByAddress($id_address) {
        $row = Db::getInstance()->getRow('
            SELECT `postcode`
            FROM '._DB_PREFIX_.'address a
            WHERE a.`id_address` = '.(int)($id_address));
        return $row['postcode'];

    public static function getZoneById($id_address)
        $postcode = self::getPostcodeByAddress($id_address);
        if (in_array($postcode, Array(1050)))
            return 1;
        elseif (in_array($postcode, Array(2000)))
            return 10;
        return 0;

[PrestaShop] Converting .htaccess to nginx include files

If you use PrestaShop and nginx, you may find this script to convert PrestaShop’s .htaccess rules into an nginx rule file useful:

print <<EOF;
fastcgi_buffers           16 128k;
fastcgi_busy_buffers_size 128k;
fastcgi_buffer_size       128k;
client_body_buffer_size   128k;
while (<>) {
    if (/^RewriteRule \^(.*) \[L\]$/) { print "rewrite ^/$1? break;\n"; }
    if (/^RewriteRule \^(.*) \[QSA,L\]$/) { print "rewrite ^/$1 break;\n"; }
    if (/^ErrorDocument (\d+) (.*)$/) { print "error_page $1 = $2;\n"; }

Save as and run with ./ <.htaccess >.htaccess.nginx. Then don’t forget to include .htaccess.nginx into your nginx site configuration and reload nginx.

If you have multiple languages or an other configuration that includes { brackets }, you may have to adapt the script.

Tested with PrestaShop …
