To run WordPress you need to ensure that your server meets certain requirements. The recommended requirements are:
- PHP version 7.2 or higher;
- MySQL version 5.6 or higher (you can also run WordPress on MariaDB 10.0 or higher);
- HTTPS support (this has become mandatory in terms of good SEO).
If you are interested in specific server software, WordPress recommends Apache or Nginx as reliable solutions that are feature-rich enough to get you started.
