请帮忙看一下 nginx 里 PHP 配置不对，网页提示重定向过多。

错误代码: INET_E_REDIRECT_FAILED

server {
listen 80;
#server_name localhost;
server_name abc.com;
root /usr/share/nginx/html/abc;
#charset koi8-r;

#access_log logs/host.access.log main;

location / {
index index.php index.html index.htm;
}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80

fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}



请问怎么修改，谢谢！
