问题描述

我正在尝试在aws beantalk上部署django应用，但我得到了500.

I am trying to deploy a django app on aws beanstalk but I get a 500.

我收到ImportError，我尝试了网络上提出的所有建议，直到最后.

I get the ImportError and I have tried all what the web has suggested, I think, to no end.

aws服务器日志中的跟踪:

我的django应用程序中有两个配置文件，位于.elasticbeanstalk内:

There are two config files in my django app located inside .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/"

这是我尝试过的:

ATTEMPT 1:有些建议可能是python版本问题.我使用python 3.4重新构建了django应用程序，与在beantalk上相同，但没有任何效果.

ATTEMPT 1: Some suggested it could be a python version issue. I re-built my django app using python 3.4, same as on beanstalk, but there was no effect.

尝试2:如建议的此处，我更改了wsgi文件的特权.为此，我将ssh放入beantalk(eb ssh)中，cd进入目录，然后:

ATTEMPT 2: As suggested here, I have changed the privileges of the wsgi file. To do this, I ssh into beanstalk (eb ssh), cd to directory and then:

$ sudo chmod a+x wsgi.py

没有效果.

ATTEMPT 3，如建议在这里，我将SOLINUX的值更改为禁用为:

ATTEMPT 3, as suggested here, I have changed the SOLINUX value to disabled as: 

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

有什么主意吗?

推荐答案

因此，显然我将配置文件保存在错误的文件夹中. .elasticbeanstalk/而不是. ebextensions/.使用后者可以解决问题.

So, apparently I had saved the config files in the wrong folder. .elasticbeanstalk/ instead of . ebextensions/. Using the latter fixed the problem.

如果git不想添加隐藏文件夹，请记住强制添加git，例如:

Remember to force git-add if the git does not want to add the hidden folder, as:

git add -f .ebextensions/
