Solve the problem of nginx+php level two page display blank

The two-level interface of the Discovery home page of the migration store shows a blank page, this HTTPS marketplace website

After modifying Nginx configuration, display normal

Add to

Location ~ [^/]\.php (/|$) {
#fastcgi_pass remote_php_ip:9000;
Fastcgi_pass Unix:/dev/shm/php-cgi.sock;
Fastcgi_index index.php;

fastcgi_split_path_info ^ (. +\.php) (/.+) $;
Fastcgi_param path_info $fastcgi _path_info;
Fastcgi_param script_filename $document _root$fastcgi_script_name;
}

This configuration means that the. php file accessed in the browser is actually read by the. php file $document _root (Web root)-that is, when accessing 127.0.0.1/ index.php, you need to read the site root directory under the index.php file, if you do not configure this configuration item, Nginx does not go back to the site root directory access. php file, so return blank

Nginx+php Four common, important configuration itemsFastcgi_pass

Role: Nginx itself does not handle PHP requests, configuration files in the. PHP end of the request through fashcgi to PHP-FPM processing, PHP-FPM is a fastcgi manager of PHP

Scope: Location, if in location

Set the FASTCGI service with a value that can be a domain name, IP address: port, or a UNIX socket file.

Nginx connects fastcgi in 2 ways: TCP and UNIX domain sockets

TCP is connected using TCP ports 127.0.0.1:9000

Sockets are socket/dev/shm/php-cgi.sock using UNIX domain sockets (many tutorials use the path/tmp, and Path/dev/shm is a tmpfs, much faster than disk)

# TCP Form pass Fastcgi_pass localhost:9000;# socket form Pass Fastcgi_pass unix:/tmp/fastcgi.socket;# passed to cluster upstream cloud {    Server cgi_1.cloud.com;    Server cgi_2.cloud.com;} Fastcgi_pass Cloud;

　

Fastcgi_param

Scope: HTTP, server, location

Sets a parameter that is passed to the FASTCGI service, which can be either text or a variable.

# For example, on the access Layer Nginx pass the following 5 parameters Fastcgi_param  remote_addr        $remote _addr;fastcgi_param  remote_port        $remote _port;fastcgi_param  server_addr        $server _addr;fastcgi_param  server_port        $server _port;fastcgi_ param  server_name        $server _name;# so on fastcgi, for example php-cgi above can be obtained by $_server this super global variable. $_server[' remote_addr ']$_server[' remote_port ']$_server[' server_addr "]$_server[' server_port ']$_SERVER[' SERVER_ NAME ']

Fastcgi_index

Scope: HTTP, server, location

When the request / ends, the request is passed to the set index.php file for processing.

Fastcgi_index Index.php;fastcgi_param Script_filename/home/www/scripts/php$fastcgi_script_name;

Fastcgi_split_path_info

Scope: Location

Nginx does not get the value of Path_info by default, it has to be assigned by specifying a regular expression defined by Fastcgi_split_path_info $fastcgi_path_info .

Purpose: to allow PHP to parse URLs like this http://www.xxx.com/index.php/abc/def
By default, when we open this URL, the page cannot be found. This will need to do path_info setup in Nginx.
principle: The index.php as php execution script, the/abc/def as a parameter passed to php-cgi execution.
implementation:Nginx version 0.7.31 support Fastcgi_split_path_info, this instruction can be set script_filename and Path_info variables, using regular expressions to separate the two parts.
Example: We add the following code to the Nginx configuration file "local" block.

Location ~ [^/]\.php (/|$) {#fastcgi_pass Remote_php_ip:9000;fastcgi_pass Unix:/dev/shm/php-cgi.sock;fastcgi_index Index.php;include fastcgi.conf;fastcgi_split_path_info ^ (. +\.php) (/.+) $;fastcgi_param path_info $fastcgi _path_info ; Fastcgi_param script_filename $document _root$fastcgi_script_name;} Restart Nginx Service/usr/local/nginx/sbin/nginx-s Reload

When Nginx processes the HTTP://WWW.XXX.COM/INDEX.PHP/ABC/DEF request, it will "index.php" as the PHP script,/abc/def as the index.php script parameters submitted to php-cgi execution.
