[Linux]PHP-FPM与NGINX的两种通讯方式

一、通过监听TCP端口通讯

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:

nignx.conf

location ~ \.php {
            root           /lroot/wwwroot/test;
            fastcgi_pass   127.0.0.1:;
            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;
        }

二、通过unix socket进程间通讯

通过配置php-fpm.d/www.conf Listen 项，php-fpm主进程启动时会在这个目录创建一个sock文件，例如/run/php-fpm.sock(注意不应选用/tmp目录)

php-fpm.d/www.conf

1.设置通讯方式

; 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.设置创建.sock文件的访问权限，以便nginx进程能够访问php-fpm创建的.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
listen.owner = nginx
listen.group = nginx
listen.mode = 

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;

        }
