How can we enable multi-site in worpress website in local?

WordPress Multisite is a powerful feature that allows you to manage multiple websites from a single WordPress installation. This is especially useful for developers, network admins, or anyone who needs to manage several sites from one dashboard. Setting up WordPress Multisite locally lets you experiment and develop in a controlled environment without impacting live sites. This article will guide you through the process of enabling WordPress Multisite on your local machine.

Prerequisites:

Before starting, ensure you have the following prerequisites:

1. A local server environment like XAMPP, MAMP, or Local by Flywheel installed on your machine.
2. A fresh or existing WordPress installation running on your local server.

Step 1: Enable Multisite in the wp-config.php File

1. Locate the wp-config.php File: This file is in the root directory of your WordPress installation. Use a text editor to open it.

2. Add the Multisite Constant: Insert the following line of code above the line that says /* That's all, stop editing! Happy publishing. */:
   

    define('WP_ALLOW_MULTISITE', true);

Step 2: Configure the Network

1. Access the WordPress Dashboard: Log in to your local WordPress site as an administrator.

2. Enable the Network Setup:

• Go to Tools > Network Setup in the WordPress admin menu.

• Choose between Sub-domains or Sub-directories based on your needs:

  • Sub-domains: Sites will be created as subdomains (e.g., site1.localhost).
  • Sub-directories: Sites will be created as subdirectories (e.g., localhost/site1).

• Provide a title for your network and an email address for the network administrator.

1. Install the Network: Click the Install button. WordPress will now provide some additional code snippets to add to your wp-config.php and .htaccess files.

Step 3: Update Configuration Files

Update wp-config.php: Add the following lines to your wp-config.php file below the line you previously added:

    define('MULTISITE', true);
    define('SUBDOMAIN_INSTALL', false); // Set to true if using subdomains
    define('DOMAIN_CURRENT_SITE', 'localhost');
    define('PATH_CURRENT_SITE', '/');
    define('SITE_ID_CURRENT_SITE', 1);
    define('BLOG_ID_CURRENT_SITE', 1);

Modify the .htaccess File: Locate the .htaccess file in your WordPress root directory. If it doesn’t exist, create one. Replace any existing WordPress rules with the following:

    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 . /index.php [L]

Save the Changes: Ensure both files are saved and closed after editing.

Step 4: Access the Network Admin Dashboard

1. Log Back into WordPress: After saving your changes, log back into your WordPress dashboard. You may need to clear your browser cache or cookies.

2. Network Administration: You will now notice a new My Sites menu in the WordPress toolbar. This menu lets you manage your network of sites, including creating new sites, managing users, and installing themes and plugins network-wide.

Step 5: Create and Manage Sites

1. Add New Sites:
- Go to My Sites > Network Admin > Sites.
- Click Add New to create a new site within your network.
- Fill in the site address, title, and administrator email, then click Add Site.

2. Manage Sites:
- Each site in your network can have its own themes, plugins, and settings.
- From the Network Admin dashboard, you can manage all sites in the network, including deleting sites, managing users, and configuring settings.

Conclusion:

Enabling WordPress Multisite on a local environment is a valuable tool for developers and site administrators who manage multiple sites. It provides a centralized way to manage, update, and maintain several sites without the need for separate installations. By following these steps, you can set up a local WordPress Multisite network efficiently and start developing or testing your websites with ease.
