nginx与php通信方式

unix socket

配置示例

location ~ \.php$ {
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_pass unix:/var/run/php7-fpm.sock;
    fastcgi_index index.php;
}

生产配置示例

php-fpm.conf

[global]
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log
log_level = notice

[www]
listen = /tmp/php-cgi.sock
listen.backlog = -1
listen.allowed_clients = 127.0.0.1
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = dynamic
pm.max_children = 100
pm.start_servers = 20
pm.min_spare_servers = 20
pm.max_spare_servers = 40
request_terminate_timeout = 100
request_slowlog_timeout = 0
slowlog = var/log/slow.log

在nginx后端api接口配置文件中有如下配置，把nginx与php通信的配置单独写到了一个文件中

include enable-php.conf;

enable-php.conf 文件内容如下

location ~ [^/]\.php(/|$)
    {
        try_files $uri =404;
        fastcgi_pass  unix:/tmp/php-cgi.sock;
        fastcgi_index index.php;
        include fastcgi.conf;
    }

而 enable-php.conf 又有 include fastcgi.conf 配置，fastcgi.conf内容如下

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  REQUEST_SCHEME     $scheme;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

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;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;
fastcgi_param PHP_ADMIN_VALUE "open_basedir=$document_root/:/tmp/:/proc/:/data/ald_api";

tcp socket

配置示例

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