【问题描述】：

我正在尝试在 ubuntu 上安装 GRAPHITE。我按照博客中的说明进行操作。

http://geek.michaelgrace.org/2011/09/how-to-install-graphite-on-ubuntu/

当我到达运行命令的部分时..我收到以下错误。我对如何解决零线索。我使用的是最新版本的 Django 1.4。

cd /opt/graphite/webapp/graphite/
sudo python manage.py syncdb


sudo python manage.py syncdb

django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

在 /opt/graphite/webapp/graphite/settings.py 文件中，这是内容。

#Database settings, sqlite is intended for single-server setups
DATABASE_ENGINE = 'sqlite3'                     # 'postgresql', 'mysql', 'sqlite3' or 'ado_mssql'.
DATABASE_NAME = STORAGE_DIR + 'graphite.db'     # Or path to database file if using sqlite3.
DATABASE_USER = ''                              # Not used with sqlite3.
DATABASE_PASSWORD = ''                          # Not used with sqlite3.
DATABASE_HOST = ''                              # Set to empty string for localhost. Not used with sqlite3.
DATABASE_PORT = ''                              # Set to empty string for default. Not used with sqlite3.

DASHBOARD_CONF = join(CONF_DIR, 'dashboard.conf')
GRAPHTEMPLATES_CONF = join(CONF_DIR, 'graphTemplates.conf')

【参考方案1】：

graphite version 0.9.10 supports Django 1.4... 但是他们将 sqlite 设置放在 django 的 local_settings.py

[mpenning@tsunami graphite]$ cat local_settings.py|grep -v \#
DATABASES = 
    'default': 
        'NAME': '/opt/graphite/storage/graphite.db',
        'ENGINE': 'django.db.backends.sqlite3',
        'USER': '',
        'PASSWORD': '',
        'HOST': '',
        'PORT': ''
    

[mpenning@tsunami graphite]$
[mpenning@tsunami graphite]$ pwd
/opt/graphite/webapp/graphite
[mpenning@tsunami graphite]$

【参考方案2】：

您需要编辑settings.py 并将DATABASES 变量的内容设置为非空字符串。旁边有 cmets 告诉你支持哪些数据库引擎：

DATABASES = 
   'default': 
        'ENGINE': 'django.db.backends.', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': '',                      # Or path to database file if using sqlite3.
        'USER': '',                      # Not used with sqlite3.
        'PASSWORD': '',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    

如果您没有安装其他任何东西，您可以将sqlite3 附加到ENGINE 字符串中，这便于在本地计算机上进行开发。

【讨论】：

你使用的是什么版本的 Django？您的设置文件中有多个 DATABASE_ 变量（这是旧方法），而您的 Django 似乎正在寻找 DATABASES 变量（这是配置数据库设置的新方法）。

已解决...我删除了 django 1.4 并使用 sudo apt-get install python-django 安装。我猜石墨不喜欢 1.4

【参考方案3】：

对于登陆这里并显示错误消息“SECRET_KEY 设置不能为空”的用户，请确保在 /opt/graphite/webapp/graphite/app_settings.py 以及您的 django 配置中设置密钥。

【参考方案4】：

我只是将DATABASES字典添加到文件末尾，它可以工作。我希望graphite可以基于Django 1.4.1运行
