[Linux]PHP-FPM與NGINX的兩種通信方式

1、經過監聽TCP端口通信

php-fpm.d/www.conf

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on
;                            a specific port;
;   '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
;                            a specific port;
;   'port'                 - to listen on 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;
            fastcgi_split_path_info ^(.+\.php)(.*)$;
            fastcgi_param PATH_INFO $fastcgi_path_info;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

2、經過unix socket進程間通信

經過配置php-fpm.d/www.conf Listen 項，php-fpm主進程啓動時會在這個目錄建立一個sock文件，例如/run/php-fpm.sock(注意不該選用/tmp目錄)

php-fpm.d/www.conf

1.設置通信方式

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on
;                            a specific port;
;   '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
;                            a specific port;
;   'port'                 - to listen on 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.設置建立.sock文件的訪問權限，以便nginx進程可以訪問php-fpm建立的.sock

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
user = nginx
group = nginx

; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in 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
;                 mode is set to 0660
listen.owner = nginx
listen.group = nginx
listen.mode = 0660

nignx.conf

location ~ \.php {
            root           /lroot/wwwroot/test;
            fastcgi_pass   unix:/run/php-fpm.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;
            include        fastcgi_params;

        }
