 +====== How to use the same Magento copy with multiple DBs and configurations ======
  
 +===== Article Updates =====
 +Updated Magento patch to allow Cache Refresh --- //[[wiki@unirgy.com|Unirgy]] 2010/02/08 05:14//
 +
 +===== Procedure =====
 +
 +==== Prepare original Magento copy for fast deployment of new copies ====
 +
 +  * Unpack Magento into ''/magento-1.3.2.4''
 +  * Apply [[#configurable_dirs_patch_for_magento_1324|this patch]], attached below
 +  * Install ALL extensions and themes that will be used in ALL copies, using PEAR or direct file copy
 +    * (Optional) Proceed with configuration of Magento in this copy, if required for extension installations.
 +  * Symlink ''/magento-1.3.2.4'' to ''/magento-latest'' for easier future upgrades
 +  * Create ''/magento-skel'' with the following structure:
 +<code>
 +/magento-skel/.htaccess - copy from /magento-latest/.htaccess
 +/magento-skel/index.php - copy from /magento-latest/index.php and follow instructions below
 +/magento-skel/js - symlink to /magento-latest/js (absolute path)
 +/magento-skel/skin - symlink to /magento-latest/skin (absolute path)
 +/magento-skel/etc - contains default configuration for new copies, copy from /magento-latest/app/etc
 +/magento-skel/etc/modules - contains all modules' manifests, for later selective disabling for each copy
 +/magento-skel/media - will contain media files, specific for each new copy
 +/magento-skel/var - will contain temporary files, specific for each new copy
 +</code>
 +
 +==== Update /magento-skel/index.php ====
 +
 +  * Make sure that ''$mageFilename'' points to absolute path of /magento-latest/app/Mage.php
 +  * Replace Mage::run() with:
 +<code php>
 +$dir = dirname(__FILE__);
 +Mage::run('', 'store', array(
 +    'etc_dir'     => $dir.'/etc',
 +    'media_dir'   => $dir.'/media',
 +    'upload_dir'  => $dir.'/media/upload',
 +    'var_dir'     => $dir.'/var',
 +    'tmp_dir'     => $dir.'/var/tmp',
 +    'cache_dir'   => $dir.'/var/cache',
 +    'log_dir'     => $dir.'/var/log',
 +    'session_dir' => $dir.'/var/session',
 +    'export_dir'  => $dir.'/var/export',
 +));
 +</code>
 +
 +==== Create a new copy of skeleton template ====
 +
 +  * Copy /magento-skel to /copy1
 +  * Update /copy1/etc/local.xml to reflect this copy's DB settings
 +    * (Optional) Create a new DB for this copy
 +    * If you do not have local.xml, proceed with Magento installation wizard
 +  * Enable/disable relevant modules in /copy1/etc/modules
 +  * Navigate to this copy's URL and wait for completion of DB install/upgrade
 +
 +===== Conclusion =====
 +
 +Now you have 1 copy of Magento core files, for unlimited number of installations and DBs, each with it's own DB, configuration, enabled extensions, sessions, temporary and media files.
 +
 +Upgrade of Magento or extensions needs to be done only once.
 +
 +===== Applications =====
 +
 +  * Development: QA copies with different configuration/databases
 +  * Running multiple stores with ease of maintenance
 +===== Configurable Dirs Patch for Magento 1.3.2.4 =====
