Please Note: Multi-Domains is for sub domain installations only and will not work well for subdirectory installations.
To Install:
1. Download the plugin file
2. Unzip the file into a folder on your hard drive
3. Upload multi-domain.php and the multi-domains-files directory to the /wp-content/mu-plugins folder on your site (if you do not have this directory you will need to create it.)
4. Upload sunrise.php to the /wp-content folder on your site – If you are using the domain mapping plugin, rename dm_sunrise.php to sunrise.php and upload it to the /wp-content folder on your site
5. Edit wp-config.php (normally located in the root of your install) and the following: define( ‘SUNRISE’, ‘on’ ); (Please ensure that you type this and not just copy and paste – Take care with the back-ticks)
As Super Admin, head over to the Multi-Domains page in your Network Admin area at Settings > Multi-Domains
Adding Domains To Your Registration Pages:
1. Enter your domain name in the spot provided.
2. Select the domain status.
- Choose Public if you want it to be available to all the users who register on your blog.
- Choose Private if you want it to be used by Super Admins only.
3. Click Add Domain. The domain will be displayed on your user and blog registration pages. At this point, you will need to do some server and domain name configuration in your hosting to make sure the blogs created work.
Server and Domain Configuration
In the DNS records for each domain added, add a wildcard subdomain that points to this WordPress installation by IP.
It should look like: A *.domain.com.
For example, here’s a domain configured with a wildcard subdomain through enom (godaddy and other domain registrars offer very similar services):
Potential Issues
Many times you may run into trouble where mapped domains don’t resolve to your WordPress Multi-site install even though the DNS is correct for the domain you are trying to map.
This is especially common with shared hosting. Some symptoms are getting a default or non-existent domain screen branded by your host. What this means is that your WordPress install/virtualhost is not set as the default for your IP address, so different domains do not load it up.
Here is a very simple way to check if your hosting is configured correctly: Simply enter your server’s IP address into a web browser and see if it loads up your WordPress signup page. For example, using the Edublogs IP you would enter http://66.135.63.39 into the web browser. See how it loads up the signup page? If entering your IP pulls up an error screen from your host (Example: http://74.54.219.243) here is what to do:
1. Purchase a dedicated IP address for your hosting.
2. Many times just the dedicated IP will do the trick. If not, you will need to tell your host to configure your WPMU virtualhost to be the default for your dedicated IP.
Of course, if you ever get stuck, just drop by the forums or live support for assistance!
