Question

我正在尝试在具有Ubuntu 14.04.1 LTS的服务器上部署我的第一个Django应用程序。我安装了apache和其他东西：

apt-get install apache2-mpm-prefork apache2-utils libexpat1 ssl-cert

然后我安装了wsgi模块：

apt-get install libapache2-mod-wsgi

我编辑了ports.conf以侦听端口8080，因为我已经在端口80上有另一台服务器，我在那里托管html + js + css资源（它们正确可用）。在准备步骤之后，我将Django应用程序移动到新的Apache服务器上，特别是移动到html目录中。然后通过添加以下内容编辑apache2.conf文件：

WSGIScriptAlias / /var/www/html/MyProjectName/wsgi.py
WSGIPythonPath /var/www/html/MyProjectName

<Directory /var/www/html/MyProjectName>
<Files wsgi.py>
Require all granted
</Files>
</Directory>

配置指令的其余部分是我使用给定命令安装Apache后的默认配置。

然后，我注意到在mods-available文件夹中，我有wsgi模块，但不在mods-enabled文件夹中，所以我在最后一个文件夹中创建了一个符号链接。

当我启动Apache时，如果我打开localhost：8080，则会出现内部服务器错误。访问error.log文件，我看到以下内容：

我从哪里开始了解问题？ 我的理解是Apache WSGI模块无法正常工作。

为了完整性，我指向的wsgi.py文件如下所示：

import os
import sys
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "MyProjectName.settings")

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

sys.path.append('/var/www/')
sys.path.append('/var/www/html/')
sys.path.append('/var/www/html/MyProjectName')

设置文件如下：

import os
BASE_DIR = os.path.dirname(os.path.dirname(__file__))
SECRET_KEY = '<some_key_here>'

DEBUG = False
TEMPLATE_DEBUG = False
ALLOWED_HOSTS = []

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'anothercustomapp',
)

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
)

ROOT_URLCONF = 'MyProjectName.urls'
WSGI_APPLICATION = 'MyProjectName.wsgi.application'

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'MyDatabaseName',
        'USER' : '<username>',   
        'PASSWORD' : '<password>', 
    }
}

SERIALIZATION_MODULES = {
    'json': 'wadofstuff.django.serializers.custom_json'
}

LANGUAGE_CODE = 'it-IT'
TIME_ZONE = 'UTC'
USE_I18N = True
USE_L10N = True
USE_TZ = True
STATIC_URL = '/static/'

在路径/ var / www / html /我有以下结构：

一个名为MyProjectName的文件夹，包含wsgi.py文件，还有一个settings.py文件，urls.py和一个空的 init .py
一个名为anothercustomapp的文件夹，包含网址，模型，视图和管理python文件，而不是空的 init .py
一个名为wadostuff的文件夹，用于序列化为json并包含与anothercustomapp相同的文件（就名称而言）

===== EDIT =====

使用以下命令安装Django和python-mysqldb之后：

apt-get install python-setuptools
easy_install django
apt-get install python-mysqldb

我最终得到以下error.log：
