You can install and set up a WordPress multisite to build a network of websites. We assume that you already installed a WordPress Single Site. Moreover we assume you have FTP access to the directory of your WordPress installation, as you need to change some files.
  1. in wp-config.php add the line
    /* Multisite */
    define(‘WP_ALLOW_MULTISITE’, true);
    above the line:
    /* That’s all, stop editing! Happy blogging. */
  2. Refresh admin dashboard page.
    Under Tools you will find the menu tab Network Setup, where you can configure your WordPress Multisite.
    Tools > Network Setup > choose Subdomain or Subdirectory
  3. Follow onscreen instructions
