Migration

Attention

The following script is to enable Varnish Cache for sites that have been created before 2.1.

  1. Login via SSH as root user.

  2. Download the script to enable varnish.

curl -sSL https://raw.githubusercontent.com/cloudpanel-io/scripts/master/varnish/enable.php > /tmp/enable-varnish.php
  1. Run the command to enable Varnish Cache for your site.

Copy the command below and replace www.domain.com with your Domain Name.

php8.1 /tmp/enable-varnish.php www.domain.com 'WordPress'

Before you can use Varnish Cache, you need to replace the vhost.

Replace Vhost
  1. Go to the Vhost of your site and make a backup.

Copy the Varnish Cache Vhost from below and replace server_name www.domain.com with your domain.

Redirect

The redirect at the beginning of the vhost from non-www to www and vice versa must stay untouched.

In this example, a redirect from domain.com to www.domain.com takes place; we need to leave it as it is and copy the new vhost template below.

  1. Done. You can now go to Settings and enable Varnish Cache.
