Question

我正在尝试使用mod_wsgi在Ubuntu 16.04上通过apache设置一个烧瓶应用程序。发生的事情是wsgi脚本无法导入任何python模块。

我已经验证了wsgi脚本是可执行的，并且已经使用python独立运行它。我还验证了我的烧瓶应用程序可以自己运行而没有错误。我能够导入我运行的任何其他python程序中的所有模块。我还安装了pip和来源的烧瓶。似乎没有什么工作。

这是我的错误日志：

这是我的flaskapp.wsgi脚本

import sys
sys.path.insert(0,'/var/www/html/flaskapp')

from flaskapp import app as application

这是我的烧瓶计划：

from flask import Flask, json, request, jsonify
import numpy as np

app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'Hello from Flask!'

if __name__ == '__main__':
    app.run()

/var/www/html/flaskapp包含flaskapp.py and flaskapp.wsgi

我缺少什么？谢谢！

修改：这是我的/etc/apache2/sites-enabled/000-default.conf

<VirtualHost *:80>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    #ServerName www.example.com

我今天正在处理这个。如果您使用的是Apache 2.4，则是一个简单的更改：

<Directory flaskapp>
        WSGIProcessGroup flaskapp
        WSGIApplicationGroup %{GLOBAL}
        Order deny,allow
        Allow from all
</Directory>

收件人：

<Directory flaskapp>
        WSGIProcessGroup flaskapp
        WSGIApplicationGroup %{GLOBAL}
        Require all granted
</Directory>

更多信息在这里： http://flask.pocoo.org/docs/1.0/deploying/mod_wsgi/#configuring-apache

另外，不确定是否有所作为，但是我的目录在apache配置中是完整路径：

    Alias /static /var/www/appname/app/static/
    <Directory /var/www/appname/app/>
            Require all granted
    </Directory>
    <Directory /var/www/appname/app/static/>
            Require all granted
    </Directory>
