Detailed configurations in nginx php

This chapter just downloaded a look at is how to support the php nginx

location ~ \.php$ {
      root           html;
      fastcgi_pass   127.0.0.1:9000;
      fastcgi_index  index.php;
      fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
      include        fastcgi_params;
}

The main problem here is learning the configuration

First, look at the location block, which is a regular match, describes all .php to the end of the section will be resolved here, we are mainly explain how this module php and communication.

fastcgi_pass match the port, this is sent to that port handling tell php

fasecgi_param Here are some more detailed configuration parameters for the

Look at the parameters of nginx fasecgi_param

fastcgi_param SCRIPT_FILENAME $ document_root $ fastcgi_script_name; Path # script file request 
fastcgi_param QUERY_STRING $ query_string; parameters # request; as ? App = 123 
fastcgi_param REQUEST_METHOD $ REQUEST_METHOD; operation (GET, POST) # request 
fastcgi_param CONTENT_TYPE $ content_type; # request header of the Content - the Type field 
fastcgi_param CONTENT_LENGTH $ content_length; # request header in the Content - length field. 
 
fastcgi_param SCRIPT_NAME $ fastcgi_script_name; # script name 
fastcgi_param REQUEST_URI $ request_uri; # requested address without parameters 
fastcgi_param DOCUMENT_URI $ document_uri; # same with $ uri. 
fastcgi_param DOCUMENT_ROOT $ document_root; # website root directory. Value specified in the instruction root server configuration
fastcgi_param SERVER_PROTOCOL $ server_protocol; # request protocol used, usually the HTTP / . 1 .0 or HTTP / 1.1 . 
 
GATEWAY_INTERFACE CGI fastcgi_param / 1.1 ; #cgi version 
fastcgi_param SERVER_SOFTWARE nginx / $ nginx_version; #nginx version number can be modified to hide 
 
fastcgi_param REMOTE_ADDR $ remote_addr; # client IP 
fastcgi_param REMOTE_PORT $ remote_port; # client port 
fastcgi_param SERVER_ADDR $ server_addr; # server IP address 
SERVER_PORT $ server_port fastcgi_param; # server port 
fastcgi_param sERVER_NAME $ server_name; # server name, domain name specified in the server configuration server_name 
 
#fastcgi_param PATH_INFO $ PATH_INFO; # can be customized variable 
 
# PHP only, required IF PHP WAS Built with - -Force-CGI-enable redirect 
#fastcgi_param REDIRECT_STATUS     200 is ; 
 
in php can print out the above service environment variables 
such as: echo $ _SERVER [ ' REMOTE_ADDR ' ]

Here are all of the information can be passed over by $ _server, and you can re-configure your own nginx SERVER

E.g:

fastcgi_param DEMO_ENV demo;

Then you can find DEMO_NEV this variable in the $ _SERVER.

This also explains why we have to be configured in the nginx and php

fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

This sentence to what they do.
