what is multisite in wordpress

 

 

 

 

 

 

As of the release of WordPress 3.0 (17 June, 2010), WordPress has included a new feature known as ‘Multisite.’ Formerly, Multisite was separate product called “WordPress Multisite” or WPMU for short. The two were integrated and now allow users to seamlessly transition from
running one WordPress install to many, without having to install multiple instances of WordPress! Multisite allows you to create additional blogs off your main install, either as subdomains or subfolders. We call this a Network and the blogs are referred to as Sites. When you use Multisite, there is one install of all
your themes and plugins, as well as only one database.
A WordPress Network is best thought of as a way to maintain multiple separate sites. Each site exists in it’s own bubble, with users, plugins, and themes all configured per-site. While it is possible to share content,
this is considered an ‘advanced’ feature.

WordPress is a well known blogging/CMS web application, popular for it’s ease of use. Once a user gets over the initial hurdle of mastering a new tool, they can configure a site in a dizzying array of ways.This eBook is intended to help you install WordPress, configure Multisite, and map domains on a Linux server running Apache. If you’ve never installed WordPress before, there will be some hurdles along the way, as Multisite is notably more complicated than running a single, stand alone, WordPress instance.
We will not be discussing how to install WordPress, nor how to find a host, set up a database or any other basic webmastering skills. If you have never attempted to run a website before, Multisite is like trying to master the high dive and learn to swim at the same time. You can do it,
but you’re making things very hard for yourself.
Furthermore, this book will not delve into wether or not you should use Multisite. No one can really answer that question for you, so you should take the time to research what Multisite is and is not before you
start.
Prerequisites
 you should already have mastered (or become familiar with) the following:
1. You already know how to install WordPress.
If you’re starting from complete zero and know nothing about how to install WordPress, start with that and then come back to Multisite.
2. You already know how to access the files on your server. Be it via SFTP or SSH or even a File Manager on your host’s control panel, you must know how to edit the files on your server.
3. You know how to access your database.
WordPress uses a database to store the content of your posts, as well as plugin settings and other site specific variables. If you don’t have access to the database, via a tool like phpMyAdmin, you will have
issues debugging.
4. You’re not afraid to open up files and look at them or edit them. One of the troubleshooting techniques this document will touch on requires you to be able to open up the WordPress files and edit them.
5. Familiarity with your server’s error logs. A good webhost can help in this respect, but knowing where the error log is will be invaluable. If you don’t know, you can always ask them.
6. You know how to turn off all plugins, and use the default theme. The first step of WordPress troubleshooting is to do that. If you can’t
there will be complications.
