Django项目python manage.py syncdb错误

Question

I am attempting to get my Django project working, on Ubuntu14.04,but I get an error message that reads:

I created my database from the command line as: root@ubuntu:~/my_blog# mysql -u root -p

 mysql> create database cs01 default charset = utf8;

My settings.py file contains:

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.

mysql seems to be complaining because you are trying to access the db you created (as root and presumably with the root password) with an empty/blank password field in your django settings file. I think you'll have to either add the root password to your settings file or (if you're understandably uneasy with placing your root password in settings) ditch your db and create a new one with credentials you can place in your settings - so that your mysql db settings and your django DATABASES setting match.

If you do this and still have permissions issues with your db, you may have to adjust your mysql config file; there should be ample online documentation to show you how to do that, if necessary.
