Generally, Jetpack works with any server that meets the requirements for WordPress itself, but there is some specific functionality that is used more in Jetpack than WordPress itself.
- XML: The Jetpack connection and various features use PHP’s XML manipulation libraries. While this is part of PHP by default, it can be built without it and increasingly, we’re seeing some server environments needing a specific package installed. If you’re seeing an error message related to PHP XML functionality, please install PHP’s XML module. Depending on your operating system, this can be done with a package manager:
sudo apt-get install php-xmlorsudo apt-get install php7.0-xml,sudo yum -y install php-xmlor by building PHP without the `–disable-xml` flag. - Ability to perform outbound HTTPS requests to jetpack.wordpress.com and
dashboard.jetpack.com.
