PHP错误日志：（运行php-cgi或spawn-fcgi，“ *** ”为安装的所有php mod）

 PHP Warning:  Module '***' already loaded in Unknown on line 0

Nginx错误日志：

 [crit] 15871#0: *12 connect() to unix:/var/run/php-fastcgi.socket failed (13: Permission denied) while connecting to upstream, client: 192.168.177.190, server: localhost, request: "GET /index.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fastcgi.socket:", host: "192.168.177.1:8000"
[error] 15871#0: *12 open() "/usr/html/50x.html" failed (2: No such file or directory), client: 192.168.177.190, server: localhost, request: "GET /index.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fastcgi.socket", host: "192.168.177.1:8000"

我想php出现这个错误与系统里运行了/usr/bin/fcgi-cgi而发生冲突有关。
如果是冲突，那能不能解决？

spawn-fcgi运行的命令：(没有php-fpm)

 /usr/bin/spawn-fcgi -s /var/run/php-fastcgi.socket -P /var/run/php-fastcgi.pid -C 2 -u www -g www -f /usr/bin/php-cgi

下面是php.ini、nginx.conf文件：

php.ini

nginx.conf

wordpress.conf

fastcgi_params_wp

使用的源：
http://downloads.openwrt.org.cn/PandoraBox/ralink/mt7620/packages/
详细的系统和软件文件及其版本明细放在了360网盘中，

希望有人能帮帮忙，即使不能解决也感谢你的留意！谢谢!
