By on July 31st, 2021

If you have been using WordPress for a long time then it might be possible that you are running more than one site at once. Running each site with a particular dashboard might be difficult to handle. Don’t worry, there is a more efficient way to create and manage a network of multiple websites from a single WordPress dashboard. Before getting started, Let’s take a look at what exactly multisite is?

What is MU(multisite)?

Using multisite you can create multiple WordPress sites on WordPress network according to your requirement with ease. This allows you to make changes easily and update all of your websites from one place. You can also add new users who can create their website under your network and limit them from accessing WordPress features.

Each site has its own media directory and database tables, but they do not have their own directories on your server.

Before Installation

Please ensure the following before beginning to install the wordpress multisite:

  • Backups your database and files
  • Pretty permalinks are activated (i.e. )
  • All plugins are deactivated
  • FTP access to upload or download files.

Setup Multisite Network

There are two choices for you when you decide to create a WordPress Multi-site network. You can either create new sites in the network on subdomains ( or sub-directories ( You can select any one of them that fits your requirements the best. In this tutorial, We will go with the most popular sub-domain method.

Note that you would have to create a DNS entry in your DNS zone file. If you haven’t created an entry, Create a CNAME record with name as “*” and host as “@“. Once the DNS entry is ready, All the random subdomains of that specific domain will point a single server. And a single server will also support multiple domains on a single application.

To set up multisite, you’ll need to access the files called wp-config.php and .htaccess. Both files will be found in the base folder of WordPress installation. Before editing, make a backup of both of those files.

Allow Multisite in wp-config.php

The first thing you need to do is set up a connection using an FTP client. Then, open up a wp-config.php file using any code editor like notepad and find the following line.

/* That's all, stop editing! Happy publishing. */

Add the following lines just before the above line.

/* Multisite */
define('WP_ALLOW_MULTISITE', true);

Now save the file.

The multisite feature is now enabled. Our next step is to install the network.
