试图用gunicorn运行django (Worker启动失败)

Question

我一直在尝试使用nginx和gunicorn部署django，目前遇到了一个问题，我遵循了SO建议的建议，我已经尝试过这种方式，建议在gunicorn文档中，但仍然没有工作…

ipals_wsgi.py

的内容

import sys
import os
import os.path
# assume we(this file) exist as a sibling to the CODE_DIR
OUR_DIR = os.path.abspath(os.path.dirname(__file__))
# apps dir is our sibling. That's where our apps are.
APPS_DIR = os.path.join(OUR_DIR, 'apps')
# env dir is also a sibling to us and ipals
ENV_DIR = os.path.join(OUR_DIR, '../env')
# activate the virtualenv
activate_this = os.path.join(ENV_DIR, 'bin', 'activate_this.py')
execfile(activate_this, dict(__file__=activate_this))

# add the apps directory to the python path
sys.path.insert(0, APPS_DIR)

# load up django

我不知道为什么你有一个名为ipals_wsgi.py的文件，它似乎在项目的顶层，或者你的设置文件在哪里。通常，Django的startproject命令会创建一个与项目同名的子目录，并在该子目录下的settings.py旁边放置一个名为wsgi.py的文件。你似乎已经修改了，但我不明白为什么。

无论如何，您的wsgi文件被调用的事实指出了问题所在:您告诉gunicorn查找一个名为ipals的文件，但如前所述，该文件名为ipals_wsgi。要么重命名文件，要么更改命令:但更可取的是，恢复到Django的默认应用程序布局——我怀疑，即使你修复了当前的问题，你也会遇到找不到设置的问题，这在默认情况下是不会发生的。
