CakePHP: tips on ssl, mysql load balance, master/slave, xhprof benchmark tool

1. CakePHP Master/Slave

*) add default(slave as for query) setting in database.php, and master for saving

*) define a new replicate behavior

<?php

class ReplicationBehavior extends ModelBehavior {



public function beforeSave($Model) {

$Model->useDbConfig = 'master';

}



public function afterSave($Model) {

$Model->useDbConfig = 'default';

}



public function setServer($Model, $server) {

$Model->__backupConfig = $Model->useDbConfig;

$Model->useDbConfig = $server;

}



public function afterFind($Model) {

if (!empty($Model->__backupConfig)) {

$this->useDbConfig = $Model->__backupConfig;

}

$Model->__backupConfig = null;

}



public function save($data = null, $validate = true, $whitelist = array()) {

$this->Replication->beforeSave($this);

return parent::save($data, $validate, $whitelist);

}



}



?>

*) set $actAs to have replicate behavior in your base app model

$actAs = array('Replicate');



*) call the setServer method in your controller to determine which database you want to use for instant query after save

if ($this->Deal->saveAll($this->data, array('validate'=>'first'))) {

$this->Deal->setServer('master');

$deal = $this->Deal->find('first',array(

'conditions' => array('slug' => $this->data['Deal']['slug']),

'fields' => array('id')

));



2. how to use xhprof (a php benchmark tool developed by facebook)

3. MySQL load-balancing

4. ssl

consolidate secure operations to single domain: https://lang.secure.jigocity.com
keep track of referer links in http header

redirect back to the original referer when done
