This video present:

• the principle of an HTTP Server,
• how apache or IIS server are working,
• what must be changed in this server to share the same Joomla instance,
• how JMS analyse the URL and how it associate each URL to a specific Joomla configuration and database connection.

This video present an overview for the creation of a demo environment and show:

• The installation of Joomla,
• The installation of Jms Multi Sites,
• The creation of a fresh slave site,
• The replication of the master website;
• The concept of the "Article Sharing for JMS";
• The concept of the "Multisites Menu Item";
• The concept of the "Multisites Contact Sharing";
• The concept of the "Mutlsites Search plugin".

If yes, go step 3 to install JMS on an existing website.
Else continue step 2 to install a fresh Joomla

is a video where we show:

• The installation of Joomla and in particular where to specify the table prefix in the DB Configuration "advance settings"
  In our sample, we have replace "jos_" table prefix by "master_"
• We also show how to create an article for the front-page

is a video that show:

• the usage of Joomla extensions install/uninstall
• the registration of Joomla Multi Sites
• the installation of the patches

Installation on Joomla 1.6

Troubleshooting:

• During the installation of JMS
  • "JFolder::create: Could not create directory"
    This message is the symptom of a permission problem.
    You may have to consider the usage of FTP Layer to increase your rights.
    See step 15
  • "ERROR: Could not find a Joomla! XML setup file in the package."
    This is the symptom that you have a size limit to upload the file into Joomla.
    JMS has a size of more 1MB and if the file can not be uploaded completly, this may result in a corrupt file to install.
    Consider in this case to "unzip" the file into a temporary directory on your server and use the alternate Joomla installation based on a directory.
    This scenario is presented in the How to install from a directory video.
    In case of Joomla 1.6 or 1.7, you have to use the subdirectory _j16 to get the manifest file for the joomla 1.6 or 1.7
• While installing the patches
  • "Unable to write entry"
    Error during installation of the file "administrator/includes/defines.php"
    "Copy failed"
    All those messages are the symptom of a problem of permission.
    To increase your rights, a simple method on Unix consists to use the FTP Layer.
    See step 15

is a video that show:

• the recommendation concerning the architecture and directory structure
• the usage of Joomla extensions install/uninstall
• the registration of Joomla Multi Sites

is a video that show:

• a review of the sub-menu present in JMS
• the usage of the Check Patches sub-menu
• where the Joomla FTP Layer setting is located in Joomla 2.5 (See also video 15)

"symbolic link" is the unix equivalent ot the windows shortcut.
This allow to create a link between folders and create a bridge (a link) between different folders.
"Symbolic Links" may be used by JMS to redirect a slave sites directory to the master website directory.
This may be usefull when you have difficulties to setup the domain or the sub-domain to share the same directory than the master website.

• Video "How to create a shortcut on windows and how it works" show:
  • Copy a directory
  • Paste shortcut

• Video "How to create a symbolic link manually on unix" show:
  
  • the usage of unix "ln -s" command
    ln -s "target_dir" linked_name

The equivalent of Shortcut in PHP language does not exists but the equivalent of the Unix Symbolic Link may be available.

The first condition is to be hosted on a Unix machine.
When you are hosted on a Windows platform, by definition the Symbolic Link in not allowed.

If you are on a Unix machine, all the hosting provider does not necessary accept to use the Symbolic Link for security reason.
If you want to know if your hosting provider accept the Symbolic Link, you can either :

• checked that with Joomla Multi Sites. Go to next step (step 6).
• or if JMS is not installed, you can use our "hello.zip" procedure that test this featur. See step 7

is a video that show:

• The setting menu where you can find the "symbolic link" allowed value
• The impact on the "slave site detail" that give access to the "deployed directory" parameter

If JMS answer that Symboli Link is forbidden, also retry with the "Hello World" procedure in the next step to have confirmation.
If the "Hello World" replies that Symbolic Link is present, then you have to check in you Global Configuration the path of the tmp and log directories.
Perhaps those temporary and log directories does not exists or correspond to a path that does not have enough permission to let JMS test the Symbolic Links.

• Go in Joomla / Site / Global Configuration
• Check the tmp and log path. Enter full path to a directory where you have permissions. In general, this is the root directory of you Joomla followed by /tmp (see server panel) and /log (see system panel)

This video show:

• Unzip of hello.zip file;
• FTP transfer of hello.txt and hello.php
• Show the result of hello.txt
• Show the result of hello.php when Symbolic Link is present

Different possibilities exists to create a slave site

If you want create a website from the "back-end, different scenario are possible

• How to create a slave sites into a sub-directory when Symbolic Link is allowed. Go to next step (step 9)
• How to create a slave sites for a domain or sub-domain (see step 10)
  
  • When "Symbolic Link" is forbidden (Not allowed)
    
    • Share the same master directory
  • When "Symbolic Link" is allowed
    • Share the same master directory
    • Redirect the slave sites specific directory to the master directory using the Symbolic Link feature

• How to create a websites from a "websites template"
  • How to create a "website template"
  • How to create a slave sites based on a "websites template"

If you want create a website from the "front-end", go to step x

• How to propose a free website creation from the front-end
• How to propose a "billable website" creation from the front-end

This video show:

• The check that that "symbolic links" is allowed
• Because we use sub-directory, this avoid the setup of the hosting provider domain or sub-domain
• Create an entry into Joomla Multi Sites
• Install the slave site using the Joomla Installation
• How to provide a specific table prefix into Joomla Installation

Sample values:

• Site ID = slave1
• Domain name = {site_url}/multisites/{site_id}
• Deploy directory = {site_dir}

This will create a slave site that will request a fresh Joomla installation.
Becarefull to enter a new table prefix in the DB configuration using the advanced panel.

Concept

• Case where "Symbolic Links" is forbidden.
  In this case, all the domain and sub-domain must be assigined to the same directory than the master website directory.
  • How to setup your hosting provider to assign the same directory than your master website.
    See FAQ : How to configure the hosting provider ?
    • How to install the "hello.zip" tool to check the hosting provider configuration. (See step 7)
    • How to check the hosting provider configuration
  • How to create a slave sites with a domain or a sub-domain with the same directory path

  See also the video in step 18 that show how to create a slave site for a sub-domain with cPanel and that share the same directory than the master website.

• Case where "Symbolic Links" is allowed.
  In this case, you can either:
  • use the procedure to share the same directory than the master as defined just before;
  • Deploy the slave site into a specific directory.
    • Define the domain or sub-domain with your "hosting provider" as you do usually.
    • If you are not sure of the path of the slave sites, install the "hello.zip" into the directory proposed by your hosting provider. (See step 7.)
    • Define the slave sites into JMS and deploy it into the specific directory like when you deploy a slave site into a sub-directory (see step 9).

This video that show:

• the creation of the JMS template rule for the subdomain
• how to create a fresh slave site from the back-end using the JMS template rule

The idea consists in the installation of the "Hello Word" (hello.txt and hello.php) into the master website root directory (documentroot) and when you want to have a slave site deployed into a specific, also in this specific directory.
You can edit the "hello.txt" to put specific text to ensure that you are reading the expected file.
To test the "hosting server" configuration, just enter the URL to the master website and also to the slave site and check if you access the expected "hello.txt" and "hello.php".

The FTP Layer is a Joomla feature only available for Unix platform.

The FTP Configuration is available when you install Joomla or after the installation into the Global Configuration.
When using the FTP Layer, this use the privilege of the user that you chosen for the FTP.
The FTP Layer is used to create folders, delete folders, create and delete files, write content into the files, ...
