[Linux] Two kinds of communication methods of PHP-FPM and Nginx

One, by listening to TCP port communication

Php-fpm.d/www.conf

; The address onwhichTo accept FastCGI requests.;   Valid syntaxes is:; 'Ip.add.re.ss:port'-To listen in a TCP socket to a specific IPv4 address on;   a specific port;; '[ip:6:addr:ess]:p ort'-To listen in a TCP socket to a specific IPv6 address on;   a specific port;; 'Port'-To listen in a TCP socket to all addresses; (IPv6 and IPv4-mapped) on a specific port;; '/path/to/unix/socket'-To listen on a UNIX socket.; Note:this value is Mandatory.listen=127.0.0.1:9000

Nignx.conf

Location ~ \.php {            root           /lroot/wwwroot/test;            Fastcgi_pass   127.0. 0.1:9000;            Fastcgi_index  index.php;             ^ (. +\.php) (. *) $;            Fastcgi_param path_info $fastcgi _path_info;            Fastcgi_param  script_filename  $document _root$fastcgi_script_name;            Include        fastcgi_params;        }

Second, through the UNIX socket interprocess communication

Select a directory to create an empty. Sock file, such as/run/php-fpm.sock ( Note that the/tmp directory should not be selected), and then configure

Php-fpm.d/www.conf

1. Set up a communication mode

; The address onwhichTo accept FastCGI requests.;   Valid syntaxes is:; 'Ip.add.re.ss:port'-To listen in a TCP socket to a specific IPv4 address on;   a specific port;; '[ip:6:addr:ess]:p ort'-To listen in a TCP socket to a specific IPv6 address on;   a specific port;; 'Port'-To listen in a TCP socket to all addresses; (IPv6 and IPv4-mapped) on a specific port;; '/path/to/unix/socket'-To listen on a UNIX socket.; Note:this value is Mandatory.listen=/run/php-fpm.sock

2. Set the access permission to create the. sock file so that the Nginx process can access the PHP-FPM created. Sock

; Unix user/group of processes; Note:the user is mandatory. If The group is not set, the default user   " s       Group  ; would be used.user  = Nginxgroup  = Nginx 

 for if one is used. In Linux, read/write on order to allow connections from a Web server. many; BSD-derived systems allow connections regardless of permissions.; Default Values:user and group are set as the running user;                  0660   == 0660

Nignx.conf

Location ~ \.php {            root           /lroot/wwwroot/test;            Fastcgi_pass   Unix:/run/php-fpm.sock;            Fastcgi_index  index.php;             ^ (. +\.php) (. *) $;            Fastcgi_param path_info $fastcgi _path_info;            Fastcgi_param  script_filename  $document _root$fastcgi_script_name;            Include        fastcgi_params;        }
