| <p><strong>This script allows you to deploy multiple installations of Joomla using one Joomla full source directory.</strong></p> | |
| <p>If you're a Joomla Web Developer like us, you probably have a lot of Joomla installations in your local server. Everytime you install Joomla, you have to duplicate the full source files. This is very inefficient if you don't modify the core files anyway. The solution is to use symlinks(symbolic links or aliases). This script will create symlinks to a Joomla source directory. But it doesn't symlink the directories that can have dynamic contents like /components and /modules. This script takes everything in consideration so your symlinked Joomla installations will work as if they are full copies of Joomla.</p> | |
| <p>A default Joomla 1.5 installation takes around 45MB of disk space. Using this script, each of your symlinked Joomla! installation directory will occupy only 2MB. It will also make the upgrades easier because you only have to upgrade one directory.</p> | |
| <p class="warning"><strong>Warning!</strong> This script was tested to work on a local UNIX environment (Linux and Mac OS X using Apache). Please help us test it for live deployments. This script will not work on Windows.</p> | |
| <p class="warning"><strong>Requirements:</strong><br /> Apache 2.x and PHP 5.2+ <br />Apache should be configured with FollowSymLinks on the directory where you want to install a symlinked Joomla! <br />PHP should be able to execute shell commands using exec()</p> | |
| <h3>Instructions</h3> | |
| <ul> | |
| </ul> | |
| <ol> | |
| <li>Edit symlink-joomla.php and configure $install_path and $source_path</li> | |
| <li>Put symlink-joomla.php within your web server's document root. It can be located at any subdirectory of the document root. </li> | |
| <li>Run symlink-joomla.php through your web browser.(You are already doing it if you can read this)</li> | |
| <li>You can install a symlinked Joomla as a subdirectory of $install_path. Just put something on the "Where do you want to install Joomla?" field. If left blank, it will install the symlinked Joomla to $install_path.</li> | |
| <li>Proceed with the installation</li> | |
| </ol> | |
| <h3>Notes:</h3> | |
| <ol> | |
| <li>Note that the $source_path can be a directory that contains sub-directories of different Joomla! 1.5 full versions (don't use patch files). If the $source_path contains sub directories, you'll be allowed to choose which one to use.</li> | |
| <li>By default, $install_path is the directory where symlink-joomla.php is located</li> | |
| <li>/images is not symlinked.</li> | |
| <li>All the core extensions are symlinked, but it doesn't symlink the directories that can contain user generated files. e.g /components/com_content is symlinked, but /components is not so that you can install components within a particular installation of symlinked Joomla.</li> | |
| </ol> | |
| <ul> | |
