How to connect a domain to your WordPress website


In this articles we’ll show you how to easily connect a new domain to your WordPress website by using SSH and WP-CLI.

Even though shell access via SSH and WP-CLI, i.e. the WordPress command line, is mostly used by advanced users, this tutorial is also well suited to beginners without any prior knowledge. You will need about 5-10 minutes to connect your domain.


Before you start, the following requirements should be met:

Connecting the domain with your website’s directory

In this step you will adjust the usage type of your domain and connect this with your website’s directory in the 1&1 Control Panel.


  • Click on your domain and select the Edit usage type item there. For your domain select usage type: webspace.
  • Select your WordPress website’s directory at target folder and confirm with save.

Tip: You can find your website’s directory in the 1&1 App Center in the detail view of your website.

  • Your WordPress website is now connected to the new domain.

Finally, we recommend that you adjust the settings for your old domain so that these are no longer displayed on your website. For this simply select an empty older or connect the domain with another website in the 1&1 Control Panel at Domains > Usage type.

If required: adjusting wp-config.php

If your website cannot be reached via the new domain after adjusting with WP-CLI, you will have to replace the old domain with the new domain in your website’s wp-config.php.

It’s that easy:

  • Connect your webspace with a FTP client such as FileZilla via SFTP.
