WordPress Multisite and Domain Mapping on 1and1.com Shared Hosting

These are just some notes about how I got WordPress Multisite and Domain Mapping running on a 1and1.com shared hosting account.

WordPress Multisite Setup

  1. Follow instructions on this page: WordPress Codex – Create a Network
  2. If you are planning to map independent domains to the various sites on your network, I recommend using the sub-directories for addresses of network sites. As far as I know, wildcard DNS isn’t an option on 1and1.com shared hosting packages.
  3. Ignore the bit about the WordPress files needing to be installed in the root directory/folder of your hosting file-space. It merely needs to be in the root folder of whatever directory/folder your primary network domain name is assigned to.

WordPress MU Domain Mapping – Installation

  1. Install the WordPress MU Domain Mapping plugin in the usual way.
  2. Once the plugin is installed, some manual configuration is necessary. Follow instructions here: wordpress-mu-domain-mapping/installation/
