django项目python manage.py同步数据库错误

Question

我试图让我的Django项目在Ubuntu14.04上工作，但我得到一个错误消息：

我从命令行创建了我的数据库: root@ubuntu:~/ my _blog# mysql -u root -p

 mysql> create database cs01 default charset = utf8;

我的settings.py文件包含：

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
    'NAME': 'cs01',                      # Or path to database file if using sqlite3.
    'USER': 'root',                      # 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.


root@ubuntu:~/my_blog# python manage.py syncdb

mysql似乎在抱怨，因为您试图使用django设置文件中的空/空密码字段访问您创建的数据库(以root用户身份，并可能使用root密码)。我认为你要么将root密码添加到你的设置文件中，要么(如果你对将你的root密码放在设置中感到不安)丢弃你的数据库，并创建一个新的凭据，你可以把它放在你的设置中-这样你的mysql数据库设置和你的django数据库设置就会匹配。

如果你这样做了，但你的数据库仍然有权限问题，你可能不得不调整你的mysql配置文件；如果必要的话，应该有大量的在线文档向你展示如何这样做。
