apache2.service未处于活动状态，无法重新加载

Question

我试图在VPS（Ubuntu 16.04.2，Apache2）上部署我的服务器python应用程序，当我写sudo service apache2 reload时，我收到这样的错误：apache2.service is not active, cannot reload.

当我想看我的系统时，我得到这个。在

systemctl status apache2.service

● apache2.service - LSB: Apache2 web server
   Loaded: loaded (/etc/init.d/apache2; bad; vendor preset: enabled)

Mar 11 19:35:00 kristicbot systemd[1]: apache2.service: Unit cannot be reloaded because it is inactive.

在那之前，我做了一些更正-默认.conf文件。我改了一下：

^{pr2}$

我的botserver.py很简单：

from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello():
        return "Hello {}".format(2+2)
if __name__ == '__main__':
        app.run(host='0.0.0.0')

~            

我的机器人服务器.wsgi公司名称：

import sys
sys.path.insert(0, 'var/www/html/bot')
from botserver import app as application

是什么导致了这个问题，我如何克服它？在
