Table of content Why did we created JMS MULTISITE (its history) ? Which are our requirement and solutions ? For whom JMS MULTISITE is designed ? What is JMS MULTISITE ?––A super switch, a dispatcher that is able to display the appropriate website depending on the domain,subdomain or subdirectoriesA set of tools to create, replicate, clone websites (a copy machine) that can be used : To supervise the installation, sharing of extensions and also supervise the dependencies between websites––From the front-end (Free or Billable websites)From the back-end to speed-up the website creation How the « super switch » is working ?–Concept of JMS MULTISITE to share the same joomla installation How a HTTP Server is working ?Functionalities present in the different version of Jms Multi Sites ? Security and proposed architecture. How to use JMS MULTISITE (the set of tools) ?–––How to create a websites from the front-end and back-end ?How to create the rules to replicate, clone a website and how to share the content of some extensionsCreation of menu item for the front-end website creation–How it is possible to share the articles ?

Our requirements & solutionsRequirements Have a unique maintenance andredure the disk spacce Be able to create website from :– The Back-end– The Front-end Be able to create a huge number of slavesites in a short time.Have a secured environment and be able tofilter the « front-end » parameters Share the users and data to avoidsynchronisations Share the individual articles(not all the articles) Have a tool to supervise the extensioninstallationSolutions to share the same joomla installation.So share the same joomladirectories. Replication (clone) of existingwebsistes that will be used astemplate.– Just change the DB parameters– Use keywords (or variable) to changedynamically some parameters Share some MySQL tables(All records or none) Articles sharing JMS MULTISITE « website tool »www.jms2win.com08-Apr-2010Page : 5

Version History Version 1.0 Version 1.1– Just share the same PHP code and require to assign the same « document root » toeach domain– Only select the appropriate « configuration.php » based on the « host » (domain orsubdomain)– Only create fresh slave sites– Introduction of the Symbolic Links functionality to allow deploy a slave site into anotherdirectory. Case where the HTTP admin tool does not allow assign a specific « document root »– Possibility to create websites from the front-end Template of websites Give the possibility to delears or branches, to create their own websites and avoid « head quarter » create allthe websitesAlso request from « templates (themes) » company to propose « ready to use » websites amoung differentthemesEtc – Possibility to replicate websites into a same DB Template of websitesVersion 1.2– Extended with the replication into another DB– Add the sharing of extensions– Creation of a « website tools » to supervise the « install », « sharing », « uninstall » ofthe extensionswww.jms2win.com08-Apr-2010Page : 13

JMS MULTISITES is A Super Switch that works like a HTTP Server to display theappropriate website based on a domain or subdomain orsubdirectory present in a URL Able to use symbolic link to share the files and folders andtherefore reduce the disk space and the number of files onthe disk Able to share the content of a limited number of extensionswith usage of MySQL sharing Able to create websites based on « templates and replicationrules »www.jms2win.com08-Apr-2010Page : 20

Why to use JMS MULTISITE ?Save times To update the content of the websites With benefit of sharing a limited number of extensions (including the users) With the sharing of articles. To create new websites : With benefit of the templates of websites ready to use. With benefit of the sharing of directories that just require creating a DB when buildinga new website. With benefit that the final user can create the websites themselves.(ie 300 persons * 1 site is easier than 1 administrateur * 300 sites). To update Joomla and its extensions as there is only one instance of thePHP code. To do backup as there is only one joomla installation to backupSave money Multi Level Marketing possiblities. Minisites specialized on some « keywords » to promote specific products and therefore increase their sales (money). Hosting less expensives. Reduce disk space Reduce the number of number of files and folders to maintain. (Maybe a solution when the number of iNodes is limited). As you save time, you win money.www.jms2win.com08-Apr-2010Page : 45
