[英]Configuring Apache WSGI for Flask on Google Compute Engine (Flask Import Error using mod_wsgi)
[英]Flask and mod_wsgi import error
我正在尝试使用mod_wsgi在Ubuntu 16.04上通过Apache设置Flask应用程序。 发生的是,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,并已与python独立运行。 我还验证了我的flask应用程序可以独立运行,没有错误。 我可以在我运行的任何其他python程序中导入所有模块。 我还安装了pip瓶和从源头安装的烧瓶。 似乎没有任何作用。
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
这是我的烧瓶程序:
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
我有什么想念的吗? 谢谢!
编辑: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
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
WSGIDaemonProcess flaskapp threads=5
WSGIScriptAlias / /var/www/html/flaskapp/flaskapp.wsgi
<Directory flaskapp>
WSGIProcessGroup flaskapp
WSGIApplicationGroup %{GLOBAL}
Order deny,allow
Allow from all
</Directory>
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
</VirtualHost>
# vim: syntax=apache ts=4 sw=4 sts=4 sr noet
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>
至:
<Directory flaskapp>
WSGIProcessGroup flaskapp
WSGIApplicationGroup %{GLOBAL}
Require all granted
</Directory>
此处提供更多信息: 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>
