9.1. Combination of PHP and httpd

Common PHP open source software:

The combination of PHP and httpd:

  Module as a module loads when needed:

  Cgi (Common gateway interface): General gateway interface, a communication tool for HTTP servers to communicate with program services on other machines. (CGI programs must run on network servers, and every time HTTP services encounter dynamic programs, they need to start a new parser.)

  Fastcgi, a scalable, high-speed interface for communication between HTTP servers and dynamic scripting languages, has the advantage of separating dynamic languages from HTTP servers. Its main behavior is to keep the CGI interpreter process in memory and thus achieve higher performance. Repeated loading of CGI interpreters is the main reason for CGI's poor performance. If CGI interpreters remain in memory and accept FastCGI process manager scheduling, they can provide good performance, scalability, Fail-Over characteristics and so on.

  LAMP configuration order: httpd - > MySQL - > PHP - > XCache (buffer / optimizer)
