WordPress MU (Mutiple User) allows unlimited, separate, individual blogs to exist on one installation, in one hosting acount.
And each individual blog can have a unique domain name with the help of Donncha’s Domain Mapping plugin.
The installation of the plugin requires a few additional steps. Here’s how to do it.
1.. Download the WordPress Mu domain mapping Plugin
2. UnZip it
3. After you unzip, you will see just three files:
domain_mapping.php
readme.txt
sunrise.php
4. FTP to your WordPress MU site, and upload the file named “domain_mapping.php” to the mu-plugins folder. Do not upload it to the regular plugins folder.
5. In the host panel of your FTP program, move up a level to your wp-content folder. Upload the file named “sunrise.php” to your wp-content folder.
6. In the host panel of your FTP program, move up to the root level of your WordPress Installation. Find the file named wp-config.php
7. Use the edit fieature of your FTP program to edit the wp-config.php file online. The only edit you need to make is to “uncomment” the line that looks like this
“// uncomment this to enable wp-content/sunrise.php support
//define( ‘SUNRISE’, ‘on’ );
And the way you “uncomment” it is to remove the two “ //” before the line that reads //define( ‘SUNRISE’, ‘on’ );
Remove the two // and save.
8. Close your FTP program and return to your WordPress MU site.
Click Manage -> Domain Mapping
You’ll know the Domain Mapping plugin is ready to use when you see this form ready to be filled in.
