Question

我試圖部署在AWS上青苗一個Django應用程序，但我得到一個500

我得到了ImportError，並且我已經嘗試了所有的網絡建議，我認爲，不會結束。

從AWS服務器日誌跟蹤：

的wsgi.py文件：

import os 
from django.core.wsgi import get_wsgi_application 
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "kirr.settings") 
application = get_wsgi_application() 

/etc/httpd/conf.d/ wsgi.conf：

有兩個配置文件我的Django應用程序位於內.elasticbeanstalk：

.elasticbeanstalk/**01_Packages.config**: 
`packages: 
    yum: 
    git: [] 
    mysql-server: [] 
    mysql: [] 
    libjpeg-turbo-devel: [] 
    zlib-devel: []` 

.elasticbeanstalk/**02_Python.config**: 
`container_commands: 
    01_migrate: 
      command: "source /opt/python/run/venv/bin/activate && python src/manage.py migrate --noinput" 
     leader_only: true 
    02_createsu: 
     command: "source /opt/python/run/venv/bin/activate && python src/manage.py createsu" 
     leader_only: true 
    03_collectstatic: 
     command: "source /opt/python/run/venv/bin/activate && python src/manage.py collectstatic --noinput" 

option_settings: 
    "aws:elasticbeanstalk:application:environment": 
     DJANGO_SETTINGS_MODULE: 「kirr.settings" 
     "PYTHONPATH": "/opt/python/current/app/src:$PYTHONPATH" 
     "ALLOWED_HOSTS": ".elasticbeanstalk.com" 
    "aws:elasticbeanstalk:container:python": 
     WSGIPath: src/kirr/wsgi.py 
      NumProcesses: 3 
      NumThreads: 20 
    "aws:elasticbeanstalk:container:python:staticfiles": 
     "/static/": "www/static/" 

這是我曾嘗試：

未遂1：Some認爲這可能是一個Python版本的問題。我使用python 3.4重新構建了我的django應用程序，與beanstalk一樣，但沒有任何效果。

嘗試2：如建議here，我已經改變了wsgi文件的權限。要做到這一點，我ssh到魔豆（eb ssh），cd到目錄中，然後：

$ sudo chmod a+x wsgi.py 

無影響。

未遂3，如建議here，我有SOLINUX值改爲禁用爲：

(venv)[ec2-user@ip-112-31-10-129 src]$ sudo nano /etc/selinux/semanage.conf 

任何想法？

Answer 1

嘗試：

WSGIDaemonProcess wsgi threads=15 display-name=%{GROUP} \ 
    python-home=/opt/python/run/venv \ 
    python-path=/opt/python/current/app/src \ 
    user=wsgi group=wsgi 

你有什麼是你的項目的父目錄不正確的路徑。也不使用首選方法來聲明Python虛擬環境的位置。

後者，請務必閱讀文檔：

• http://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html

另請參閱Django文檔：

• https://docs.djangoproject.com/en/1.10/howto/deployment/wsgi/modwsgi/

由於你只運行一個WSGI應用程序，也建議你設置：

WSGIApplicationGroup %{GLOBAL} 

Answer 2

所以，顯然我已經將配置文件保存在錯誤的文件夾中。 .elasticbeanstalk/而不是. ebextensions/。使用後者解決了這個問題。

記住強制混帳添加如果Git並不想要添加的隱藏文件夾，如：

git add -f .ebextensions/
