How to Install and Set Up WordPress Multisite Network?

WordPress Multisite is a powerful feature that allows you to run multiple WordPress sites from a single installation. Whether you’re managing a network of blogs, a collection of client websites, or a portfolio of company sites, Multisite can help you efficiently manage all your sites in one place. Here’s a comprehensive guide on how to install and set up a WordPress Multisite network.

Step 1: Prepare Your WordPress Installation

Before enabling Multisite, ensure your WordPress installation is ready. This includes backing up your site and updating WordPress to the latest version.

• Backup Your Site: Use a backup plugin like UpdraftPlus or BlogVault to create a full backup of your WordPress site, including the database and files.

• Update WordPress: Ensure you are running the latest version of WordPress. You can check for updates in the dashboard under Dashboard > Updates.

Step 2: Enable Multisite in wp-config.php

To enable Multisite, you need to add a line of code to your wp-config.php file.

• Access wp-config.php: Use an FTP client or your hosting provider’s file manager to locate the wp-config.php file in the root directory of your WordPress installation.

• Add the Multisite Line: Add the following line of code above the line that says /* That's all, stop editing! Happy blogging. */:phpCopy codedefine('WP_ALLOW_MULTISITE', true);

Save the changes and upload the file back to your server if using FTP.

Step 3: Configure the Network Settings

After enabling Multisite, you need to configure the network settings from the WordPress dashboard.

• Deactivate All Plugins: Go to Plugins > Installed Plugins and deactivate all active plugins. This helps prevent conflicts during the setup process.

• Access the Network Setup: In the WordPress dashboard, go to Tools > Network Setup. You will see a screen where you can configure your network.

• Choose Subdomain or Subdirectory: Decide whether you want to use subdomains (e.g., site1.example.com) or subdirectories (e.g., example.com/site1). Note that subdomains require wildcard DNS records.

• Fill in Network Details: Provide a title for your network and an email address for the network administrator.

• Install the Network: Click the Install button to proceed.

Step 4: Update Configuration Files

After configuring the network, you will be provided with code snippets to add to your wp-config.php and .htaccessfiles.

• Add Code to wp-config.php: Copy the provided code and add it to your wp-config.php file just below the line you added earlier:

define('MULTISITE', true); define('SUBDOMAIN_INSTALL', false); // Set to true if using subdomains $base = '/'; define('DOMAIN_CURRENT_SITE', 'example.com'); define('PATH_CURRENT_SITE', '/'); define('SITE_ID_CURRENT_SITE', 1); define('BLOG_ID_CURRENT_SITE', 1);

• Update the .htaccess File: Copy the provided rewrite rules and replace any existing WordPress rules in your .htaccess file:

RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] # Add a trailing slash to /wp-admin RewriteRule ^wp-admin$ wp-admin/ [R=301,L] RewriteCond %{REQUEST_FILENAME} -f [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^ - [L] RewriteRule ^(wp-(content|admin|includes).*) $1 [L] RewriteRule ^(.*\.php)$ $1 [L] RewriteRule . index.php [L]

Save the changes and upload both files back to your server.

Step 5: Network Administration

Now that your network is set up, you can start adding sites and managing the network settings.

• Log in Again: Log out and log back into your WordPress dashboard to access the network admin settings.

• Network Dashboard: In the dashboard, you will see a new My Sites menu. Go to My Sites > Network Admin > Dashboard to access the network admin dashboard.

• Add New Sites: To add a new site, go to Sites > Add New and fill in the required details like site address, title, and admin email.

• Manage Sites and Users: From the network dashboard, you can manage all sites and users across the network, install and activate themes and plugins for the entire network, and configure network settings.

Step 6: Reactivate Plugins

Once your network is set up and running smoothly, you can reactivate your plugins.

Go to Plugins > Installed Plugins and activate the necessary plugins. You can choose to network activate plugins, making them available across all sites in the network.
