LAMP

CGI与FASTCGI区别:

CGI：公共网关接口，碰到动态请求，web服务器会fork一个新进程，来运行外部的程序，处理完后的数据返回给web服务器，web服务器把内容发送给用户fork的进程也就退出。不可复用。 请求流程：Client -- (http协议) --> httpd -- (cgi协议) --> application server (program file) -- (mysql协议) -->mysql

fastcgi：收到动态请求后把请求时，web服务器直接把内容传递给这个进程，这个进程收到请求后进程处理，把结果返回给web服务器，然后接着等待下一个请求到来再处理，而不是退出。 请求流程：Client -- (http协议) --> httpd -- (fastcgi协议) --> fastcgi服务器 -- (mysql协议) --> mysql
