Nginx: Configuration Detailed description

First, fastcgi param details:

Fastcgi_param Script_filename$document _root$fastcgi_script_name;# Path of the script file request Fastcgi_param query_string$query _string;# the requested parameter; app=123  .Fastcgi_param Request_method$request _method;#requested action (Get,post)  Fastcgi_param Content_Type$content _type;# the Content-type field in the request header Fastcgi_param content_length$content _length;#请求头中的Content the-length field. Fastcgi_param Script_name$fastcgi _script_name;# script name Fastcgi_param Request_uri$request _uri; # requested address with no parameters Fastcgi_param Document_uri$document _uri;# Same as $uri.  Fastcgi_param Document_root$document _root;#the root directory of the Web site. The value specified in the root directive in the server configuration   Fastcgi_param Server_protocol$server _protocol;# the protocol used by the request, usually http/1.0 or http/1.1.  Fastcgi_param gateway_interface CGI/1.1;# CGI version Fastcgi_param Server_software nginx/$nginx _version;#nginx version number, can be modified, hiddenFastcgi_param remote_addr$remote _addr;#客户端IPFastcgi_param Remote_port$remote _port;#客户端端口Fastcgi_param server_addr$server _addr;#服务器IP地址Fastcgi_param Server_port$server _port;#服务器端口Fastcgi_param server_name$server _name;#服务器名, the domain name is specified in the server configuration in the server_name # fastcgi_param path_info $path _info; #可自定义变量  # PHP only, required if PHP is built with--enable-force-cgi-redirect # fastcgi_param redirect_status; 

Second, the Nginx configuration file

First on a copy of my nginx.conf!
