FastCGI

　　将脚本解析服务器和HTTP服务器分离开来，同时还能在脚本解析服务器上启动一个或多个脚本解析守护进程。当HTTP服务器遇到动态程序时，可以将其直接交付给FastCGI进程执行，然后将得到的结果返回给浏览器。这种方式可以让HTTP服务器专一地处理静态请求，将动态服务器的结果返回给客户端，很大程度上提高了整个应用系统的性能。PHP动态语言服务端可以启动多个FastCGI的守护进程（php-fpm），HTTP服务通过FastCGI客户端（Nginx fastcgi_pass）和动态语言 FastCGI服务端（php-fpm）通信。

安装php-7.3.5

# 依赖
[root@localhost nginx-1.16.0]# yum install zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpngdevel gd-devel libcurl-devel libxslt-devel -y

# 检查是否安装成功
[root@localhost nginx-1.16.0]# rpm -qa zlib-devel libxml2-devel libjpeg-turbo-devel libiconv-devel

libxml2-devel-2.9.1-6.el7.5.x86_64
libjpeg-turbo-devel-1.2.90-8.el7.x86_64
提示：缺少libiconv-devel

[root@localhost nginx-1.16.0]# rpm -qa freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel
