Nginx 502坏网关-拒绝许可

我在谷歌上搜索了一天左右，尝试了几种解决方案。我不知道是什么导致了这个错误。下面的内容可能有点长，我很抱歉——我试图预测一些常见的反应，试图帮助诊断问题:)

2014/05/11 17:26:00 [crit] 29833#0: *31 connect() to unix:/var/run/php/default.sock failed (13: Permission denied) 

我的vhost配置是:

server {
        server_name             .lone0001.ca;
        listen                  80;
        root            /home/lone0001/public_html;
        error_log       /home/lone0001/.nginx/logs/error.log;
        access_log      /home/lone0001/.nginx/logs/access.log;
        include         /etc/nginx/includes/global/robots.conf;
        include         /etc/nginx/includes/global/wordpress.conf;
        include         /etc/nginx/includes/lone0001_php.conf;
}

PHP配置(包括)如下:

location ~ '.php$ {
        try_files               $uri =404;
        fastcgi_split_path_info ^(.+'.php)(/.+)$;
        include                 /etc/nginx/includes/global/fastcgi_params;
        fastcgi_index           index.php;
        fastcgi_param           SCRIPT_FILENAME         $document_root$fastcgi_script_name;
        fastcgi_pass    unix:/var/run/php/lone0001.sock;
}

现在，我的php fpm池配置如下(缩写):

"lone0001.conf"

:

[lone0001]
user = lone0001
group = lone0001
listen = /var/run/php/lone0001.sock
listen.owner = lone0001
listen.group = lone0001
listen.mode = 0666

"www.conf"

:

[www]
user = www-data
group = www-data
listen = /var/run/php/default.sock
listen.owner = www-data
listen.group = www-data
listen.mode = 0666

文件权限您可能会问?

superuser@myserver:/etc/php5/fpm/pool.d# ls -l /var/run/php/
total 0
srwxrwxr-- 1 www-data    www-data    0 May 11 17:21 default.sock
srwxrwxr-- 1 lone0001    lone0001    0 May 11 17:21 lone0001.sock

一些笔记:

我试过chmod -Rf 0666 /var/run/php，我试过将PHP套接字移动到/tmp(没有成功)。我还尝试切换我的vhost到我的"默认"PHP套接字，但无济于事。

user www-data;
events {
.....
.....
}
http {
.....
.....
}
