How To Setup WordPress Multisite
With WordPress 3.0 and above, you have the ability to create a network of sites by using the multisite feature. Multisite is a powerful WordPress feature that can be used by small, medium, and large websites.
It enables you to create multiple websites from single WordPress installation. This lets you turn your website into a network of websites.
With WordPress you can create new sites instantly and manage them using the same username and password on the entire network of sites. You can also allow users to create a site on your network.
You can install multisite on sub-domain (site1.example.com) or sub-directory (example.com/site1). With this tutorial you will be able to install and create WordPress multisite network on a sub-directory. We recommend a sub-directory, as installing on sub-domain will require you to add a wild-card sub-domain on your hosting server, which is not allowed when you are using their basic shared hosting plan.
Before you begin you need to ask yourself two questions. First, why you need a multisite network. Second, how it will serve your purpose and objectives. As rolling back to single WordPress Installation will require lots of work.
Creating a multisite network can be useful for business that has different locations and branches. It can benefit government or non-profit organization with different departments, locations, and regions. It can benefit you when you want to start a network of websites with different niches, or when you want to start networks of blogs for users, just like WordPress.com.
