Introduction to static and dynamic separation of Nginx

The static processing capacity of Nginx is very strong, but the dynamic processing capacity is insufficient, so the static and dynamic separation technology is commonly used in enterprises.

Static and dynamic separation for PHP

● static pages are handed over to Nginx for processing

● dynamic pages are handed over to PHP-FPM module or Apache for processing

In the configuration of Nginx, different processing methods of static and dynamic pages are realized through location configuration segment combined with regular matching.

Principle of Nginx reverse proxy

Nginx not only acts as a Web server, but also has the functions of reverse proxy, load balancing and caching. Nginx uses the proxy module to proxy the client's request to the upstream server, where nginx and. The upstream server is connected through the http protocol. The most important instruction of Nginx in implementing reverse proxy function is proxy_ _ pass, which can and can schedule user requests to. Upstream server.

Nginx dynamic and static separation examples demonstrate requirements and architecture:

According to the needs of the enterprise, the static and dynamic separation is realized by configuring Nginx, the request for the php page is forwarded to L AMP for processing, and the static page is handed over to Nginx for processing to achieve static and dynamic separation.
