使用 mod_wsgi-express 创建的网站响应时间过长

Question

我使用 Flask 创建了一个 Web API，我正在使用 mod_wsgi-express 部署它。如果我连接到同一台服务器，我会遇到一个问题，我可以很容易地连接到该网站。但是，当我尝试从外部连接到该网站时。该站点响应时间过长，错误日志文件或访问日志文件中未提及任何内容

我把 mod_wsgi 安装到了 python2.7.3

这是我从终端运行发出的命令

mod_wsgi-express start-server configure.wsgi --server-root /home/xarxes_ub/python_code/Error_log/ --user www-data --group www-data --host serverIP --port 8000

其中 Configure.wsgi 是设置应用程序（为了完整起见，我在下面插入了它）

from MenuUB2 import app as application

import sys
sys.stdout = sys.stderr

命令行生成mod_wsgi-start-server生成Httpd.conf文件

为了方便大家，我插入了下面的文件

<IfModule !version_module>
LoadModule version_module '${MOD_WSGI_MODULES_DIRECTORY}/mod_version.so'

服务器的防火墙是否可能阻止了对该站点的所有外部请求（外部请求，如未连接到同一 LAN）我的服务器运行ning Ubuntu 12.04.5 LTS 无论哪种方式，我运行 sudo iptables -L 都得到了以下结果

非常感谢能得到的任何帮助

我使用像这个这样的端口敲门网站检查了端口 8000 http://www.canyouseeme.org/

我发现端口被关闭了。唯一开放的端口是端口 80 和 22。我正在使用的服务器显然有一个我无权访问的防火墙。

因此我不得不更改端口 80 上的 httpd.conf 文件并添加以下行

 WSGIScriptAlias /submitFrame /home/xarxes_ub/python_code/configure.wsgi
 WSGIDaemonProcess MenuUB2 threads=5 

<Directory /home/xarxes_ub/python_code>
            # WSGIScriptReloading On
        WSGIProcessGroup MenuUB2
            WSGIApplicationGroup %{GLOBAL}
            Order deny,allow
            Allow from all
</Directory>

使用 mod_wsgi-express 创建的网站响应时间过长

Site made with mod_wsgi-express takes too long to respond
