The purpose of this example is to demonstrate how to use a single installation of WordPress on a server and run multiple websites or WordPress blogs with different domain names.

What it takes :

  • WordPress updated version (February 2011 = 3.0.5)
  • PHP version 4.3 or higher
  • MySQL version 4.0 or higher
  • Apache mod_rewrite (Linux Hosting recommended)
  • Wildcard CNAME record for subdomains
  • Activation Procedures for Multisite with sub-domain option
  • Plugin : WordPress MU Domain Mapping
  • Access to DNS management interface

Step 1 : Enable Multisite function with sub-domain
