Configure Varnish (TM) for PrestaShop

Before running the commands shown on this page, you should load the Bitnami stack environment by executing the installdir/use_APPNAME script (Linux and MacOS) or by clicking the shortcut in the Start Menu under “Start -> Bitnami APPNAME Stack -> Application console” (Windows). On OS X VMs, the installation directory is /opt/bitnami and OS X VM users can click the “Open Terminal” button to run commands. Learn more about the Bitnami stack environment and about OS X VMs.

NOTE: The steps below assume that PrestaShop is already running at the root URL of the server, such as at, and that Varnish ™ is enabled. Varnish ™ is disabled by default, but you can enable it by following the instructions in our Varnish ™ guide.

Download the different files used in the example:

Follow the steps below to configure PrestaShop with Varnish ™:

  • Connect to the server via SSH.

  • Back up the original Varnish ™ configuration file:

    $ sudo cp installdir/varnish/etc/varnish/default.vcl installdir/varnish/etc/varnish/default.vcl.backup
  • Add the PrestaShop-specific Varnish ™ configuration by downloading the corresponding file and copying it to the correct location:

    $ sudo cp prestashop.vcl installdir/varnish/etc/varnish/default.vcl
    $ sudo sed -i 's/port\s*=\s*"[^"]*"/port = "80"/g' installdir/varnish/etc/varnish/default.vcl

Varnish ™ and PrestaShop are now configured.

IMPORTANT: Varnish ™ is connected to Apache locally so other applications like phpMyAdmin or phpPgAdmin could become public. Find out how to block these applications.

Next, proceed to test and activate the Varnish ™ service as described below:

  • Restart the Varnish ™ service:

    $ sudo installdir/ restart varnish
  • Open port 81 in the server firewall. Refer to the FAQ for instructions.

  • Check if the website is being served properly by Varnish ™ on port 81, by browsing to http://localhost:81.

  • If Varnish ™ is working correctly, switch the Apache and Varnish ™ ports and activate Varnish ™ on port 80:

     $ cd installdir
     $ sudo sed -i 's/^\s*Listen .*$/Listen 81/g' apache2/conf/httpd.conf
     $ sudo sed -i 's/\:80/\:81/g' apache2/conf/bitnami/bitnami.conf
     $ sudo sed -i 's/at port.*"/at port 81"/g' apache2/scripts/
     $ sudo sed -i 's/\:80/\:81/g' apps/*/conf/httpd-vhosts.conf
     $ sudo sed -i 's/=80/=81/g' properties.ini
     $ sudo sed -i 's/port\s*=\s*"[^"]*"/port = "81"/g' varnish/etc/varnish/default.vcl
     $ sudo sed -i 's/VARNISH_PORT=.*$/VARNISH_PORT=80/g' varnish/scripts/
  • Restart the services:

    $ sudo installdir/ restart
  • Remove the firewall rule added for port 81.

IMPORTANT: Varnish ™ does not cache content if the Apache PageSpeed module is enabled. Find out how to disable this module.
