php-fpm 启动后没有监听端口9000

location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;    #将请求转发给本机9000端口，PHP解释器
            fastcgi_index index.php;
            #fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include        fastcgi.conf;
        }
