mysql - 将 Django 项目连接到远程 Mysql 数据库

Question

我正在我的本地主机上开发一个 Django 项目，我想使用一个远程的 MySQL 数据库。

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，我得到了这个错误:

在带有 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 本地主机？

所以我创建了一个名为 osx 的新用户，并拥有所有授予的权限。但它仍然不起作用。

如果你能帮助我，谢谢你

我找到了一个解决方案:

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

然后我运行 sudo service mysql restart

它似乎可以工作(没有错误)
