python manage.py syncdb无法正常工作

我玩过Django，python和MySQL;并且在导入django时安装并使它们工作，通过python命令行导入MySQLdb。python manage.py syncdb无法正常工作

但是当我尝试在项目的根目录执行Python manage.py执行syncdb，我得到了以下错误信息：

什么是可能出现的问题？似乎连接错误的东西？我在这里是新手，感谢您的帮助:)

我重视我的settings.py文件：

我可以成功登录到MySQL数据库使用命令行：mysql的本地主机-u

使得主机=“127.0.0.1”后，我得到了一个更新的错误消息：

它不能连接到数据库。请检查最后一行 – HungryCoder

你试图连接到一个MySQL数据库，当你不是这个mysql服务器的时候，你正在引用“localhost” –

更新这个问题并添加你的'settings.py'文件 –

您在数据库中缺少HOST设置。请使用localhost或127.0.0.1。

显然，当未指定主机时，mysqldb默认使用unix域套接字而不使用常规主机名/端口。

Hi Plaes，HOST的空白表示它是本地主机。我补充说，即使是为了尝试的目的，但仍然无法正常工作。不管怎么说，还是要谢谢你。 – leoooo

@leoooo当错误信息显示：'''无法通过socket'/opt/local/var/run/mysql5/mysqld.sock'（13）“）连接到本地MySQL服务器时， “HOST”值有问题 – plaes

我将HOST的空字符串替换为“127.0.0.1”，并得到了我在原始文章中编辑的上述错误... – leoooo

您需要先在MySQL中创建一个模式（让我们将其命名为my_db_schema），然后在NAME下指定它的名称。

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.mysql', 
     'NAME': 'my_db_schema',      
     'USER': 'localhost',     
     'PASSWORD': '',     
     'HOST': '',      
     'PORT': '',      
    } 
}

我正面临完全相同的问题。 settings.py中的DATABASES需要为HOSTNAME和PORT设置值。

在我的情况下，mysql使用主机“localhost：3306”。当我将PORT（在settings.py中）的值设置为3306时，它可以工作。

只需添加数据库名和端口号..

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.mysql', 
     'NAME': 'Database_name',     
     'USER': 'root',      
     'PASSWORD': 'root',     
     'HOST': '',      
     'PORT': '3306',     
    } 
}
