Question

我正在使用本地主机上的Django Project，我想使用一个距离MySQL Database。

我的本地主机IP是： 172.30.10.XX

我的MySQL远程服务器是： 172.30.10.XX

在我的 Django settings.py 文件中，我写道：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'DatasystemsEC',
        'USER': 'root',
        'PASSWORD': '*****',
        'HOST': '172.30.10.XX',
        'PORT': '3306',
        'OPTIONS': {
            'init_command': 'SET innodb_strict_mode=1',
        },
    }
}

我的数据库名称是：DatasystemsEC

但是，当我运行：python manage.py migrate时，我收到此错误：

在使用phpmyadmin的MySQL上，我有：

我假设我需要配置一个新用户才能注册我的MacOSX localhost？

所以我创建了一个名为osx的新用户，该用户拥有所有授予的权限。但它仍然无效。

谢谢你，如果你能帮助我

Answer 1

我找到了解决方案：

在我的my.cnf文件中，我添加了以下行：

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
bind-address=172.30.10.XX

我运行sudo service mysql restart

似乎工作（没有错误）

Answer 2

您创建的所有用户都只能在localhost中使用（当您使用ssh到服务器时）。

您应该拥有可以从外部访问的用户，但要小心限制其他入侵者的访问权限

您的用户的主机名应更改为例如您的IP地址

将Django Project连接到远程Mysql数据库
