nginx 訪問 php 頁面提示 connect reset by

我在兩臺機器上部署了 nginx 和 php 後，配置了 nginx 支持 php，也啓動了 php-fpm，當我訪問的時候直接報錯了，也不知道什麼緣由

nginx 搭建

安裝 php

[root@master2 ~]# yum install php php-fpm
[root@master2 ~]# vim /etc/php-fpm.d/www.conf
........
listen = 0.0.0.0:9011
user=nginx
group=nginx
listen.allowed_clients=any
........
[root@master2 ~]# cat /usr/local/var/www/index.php
<?php
phpinfo();

當訪問的時候nginx 日誌報錯以下。當訪問不頻繁的時候報的是第二條，頻繁的時候報的是第一條，沒法返回正常頁

[root@master1 ~]# cat /var/log/nginx/error.log

誰知道這兩個問題怎麼解決？麻煩提供一下解決思路。

PS:已經解決完了，問題是由於listen.allowed_clients=any參數的問題，按照官方的解釋是：容許那些fastcgi客戶端來進行鏈接，若是留空的話會容許全部的主機，默認值爲any，設置爲any不生效，註釋掉這個配置就能夠正常訪問了
