修改Nginx配置

http{
  log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for" '

  # 默认值是no，如果是CN则设置为yes

网站server配置

      return 403;
    }
  }

  error_page 403 /403.html;
  location = /403.html {
    root /usr/local/nginx/html;
    internal;
