What Is WordPress Multisite Domain Mapping and Why Do You Need It?

WordPress Multisite is one of the most popular features of WordPress that enables you to manage multiple websites using the same WordPress installation. If you have multiple websites, you can manage them all using a single WordPress installation.

It is an advanced feature that lets you manage WordPress in multiple different domains.

A WordPress Multisite can install new themes and plugins and make them available to the websites on the network. You can also customize the themes for all the websites. 


How to Set Up WordPress Multisite Domain Mapping?

To set up WordPress Multisite domain mapping, you will need a WordPress hosting company that supports WordPress multisite subdomain and WordPress multisite, and a domain name for your WordPress Multisite Domain Mapping. 

Here, in this tutorial, we have used SiteGround.  

Step :1 Installing WordPress Multisite

The first step to creating a WordPress Multisite Domain Mapping, you will need WordPress. Once you install WordPress, you will have to select the hosting company. Most WordPress hosting companies come with a one-click WordPress installer. Once done with the installation, you will have to enable the WordPress Multisite feature. 

WordPress Multisite Domain mapping is the built-in feature of WordPress. To enable it, you will need to edit the wp-config.php file.  The wp-config.php file is the WordPress file that has all the important configurations for a WordPress installation. You can find the wp-config.php file under the root folder of your website.

Once you find the wp-config.php file, you will find an option to edit it. Add the following lines. 

define ( ‘WP_ALLOW_MULTISITE’, true );

Add the lines mentioned above, save your changes, and upload the file back to your website. 

Once you upload your file, you need to go back to the WordPress admin dashboard and reload the admin dashboard. Next, you will need to configure your WordPress Multisite Network. For that go to “Tools” and search for “Network Setup”.

You will have to add the second code to your .htaccess file and replace the default WordPress .htaccess rules. Once done with adding both codes to their respective file, you will have to log in to your WordPress admin dashboard.
