我正在尝试在Amazon Linux AMI上运行一个简单的python烧瓶应用程序。我能够显示Amazon Linux AMI测试页面,但是当我尝试创建正确的配置来运行我的应用程序时,我面临着同样的问题。

我的app.py:

from flask import Flask
app=Flask(__name__)

@app.route('/')
def home():
    return "Hello World!"

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

我的app.wsgi:

import sys
import site
import os
# Add virtualenv site packages
site.addsitedir(os.path.join(os.path.dirname(__file__), '/env/lib/python2.7/site-packages'))

activate_this = '/var/www/flaskapp/env/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))

# Path of execution
sys.path.insert(0,'/var/www/flaskapp')

#import the app
from app import app as application

和我的httpd.conf:

<VirtualHost *>
    ServerName ec2....
    WSGIDaemonProcess app threads=5 home=/var/www/flaskapp/ python-path=/var/www/flaskapp/env/lib/python2.7 threads=1

    DocumentRoot /var/www/flaskapp

    WSGIScriptAlias / /var/www/flaskapp/app.wsgi
    <Directory /var/www/flaskapp>
            WSGIProcessGroup app
            WSGIApplicationGroup %{GLOBAL}
            Order deny,allow
            Allow from all
    </Directory>
</VirtualHost>

如果我看看virtualenv wit pip freeze中安装了什么,我得到了这个:

click==6.6
Flask==0.11.1
itsdangerous==0.24
Jinja2==2.8
MarkupSafe==0.23
Werkzeug==0.11.11

所以安装了Flask。为什么我无法导入它?我做错了什么?

感谢

在EC2 / EB上,通过上传zip文件,通过控制台部署烧瓶应用程序。 将烧瓶应用程序保存为PC上的普通烧瓶应用程序。我猜AWS会自动处理WSGI。

请执行以下操作:

application = app = Flask(__name__)
......
......
application.run()

将此主文件另存为“application.py”

通过AWS控制台进行压缩和上传,它将运行。

转到/ var / www / html文件夹,然后在该目录中安装flask。 使用sudo命令相同。 然后您的应用应该可以工作,
