PHP uses file storage to implement caching In some database data record large, but the server is limited, maybe a MySQL query will be good hundreds of milliseconds, a simple page generally also has more than 10 queries, this time also a page load down basically several seconds, if the concurrency is high, the server basically paralyzed, Cause a page for a long time also load not down, this time we can use

PHP defaults to using file storage session, if the concurrent volume is large, the efficiency is very low. and Redis support for high concurrency is excellent, so you can use Redis instead of file storage session. Here, introduce the function of PHP Session_set_save_handler function and use method. This function define

Problems encounteredFor Web applications, when using a single server, the files uploaded by the client are generally stored on this server. But in the cluster environment will not work, if each server to store their own received files, it is a mess, the database clearly has this attachment record, but can not find this file. As a result, the files need to be centrally managed and provide a unified path to the servers in the cluster.Implementation of d
