升级到ubuntu 16.04后,无法在MySQL上迁移django数据库

Question

在ubuntu 16.04上重新安装系统并在第一次尝试运行时python manage.py makemigrations遇到以下错误:

django.db.utils.OperationalError: (1193, "Unknown system variable 'storage_engine'")

我的django数据库设置是:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'license_portal',
        'USER': '****',
        'PASSWORD': '****',
        'HOST': '127.0.0.1',
        'PORT': '3306',
        'OPTIONS': {
            "init_command": "SET storage_engine=MyISAM",
        },
    },
}

Answer 1

在努力解决这个问题后,我发现问题是MySQL 5.7版本的变化.

使用MySQL 5.7命令SET storage_engine=MyISAM将无法正常工作,因此问题就出现了!

正如在MySQL 5.7文档中发现的那样使用default_storage_engine!我的配置变为:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'license_portal',
        'USER': '****',
        'PASSWORD': '****',
        'HOST': '127.0.0.1',
        'PORT': '3306',
        'OPTIONS': {
            "init_command": "SET default_storage_engine=MyISAM",
        },
    },
}
