Don'；我不知道如何调试nginx错误日志

我在配置nginx时遇到问题。 当我进入web浏览器时，我得到一个错误的网页。抱歉，您正在查找的页面当前不可用。请稍后再试。。。。你忠实的，nginx。 有人能帮我调试nginx-error.log文件并帮我配置服务器使其正常工作吗

问候

这是我的配置文件：
nginx.conf文件

user nginx;
worker_processes  auto;
error_log       /var/log/nginx/nginx-error.log debug;
pid        /var/run/nginx.pid;

events {
   use epoll;
}

http {

    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format main   '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent"
                      cache: $upstream_cache_status '
                      'upstream: $upstream_addr in $upstream_response_time sec';

    access_log /var/log/nginx/nginx-access.log main;

    sendfile        on;
    #keepalive_timeout  65;

    include /etc/nginx/conf.d/webportal.conf;

    }

webportal.conf

                fastcgi_pass   127.0.0.1:9000;

              }

        location /upload/ {
                try_files $uri @dynImage;
                rewrite_log on;
        }
    }

    location @dynImage {
         rewrite (([^/]+)\.(jpe?g|png))(\?(\d))?&?(random=\d+?)?$ /image_loader.php?file=$1&$query_string;
    }

    #error_page  404              /404.html;
    # redirect server error pages to the static page /50x.html
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

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

这是nginx-error.log

——您的PHP代码很可能出错，nginx正在拦截它并返回错误页面

是！干得好，先生！我现在可以前进了。非常感谢。
