一 修改settings里面的配置文件
import pymysql # 一定要添加这两行!通过pip install pymysql! 或者pycharm 里面安装 pymysql.install_as_MySQLdb() DATABASES = { \'default\': { \'ENGINE\': \'django.db.backends.mysql\', \'NAME\': \'mysite2\', \'USER\':\'root\', \'PASSWORD\':\'2GXXXXl\', \'HOST\':\'39.108.113.213\', \'PORT\':\'3306\', } }
二 报错
django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3
百度之后发现 找到对应项目的 django\db\backends\mysql\base.py文件
注释
if version < (1, 3, 3):
raise ImproperlyConfigured("mysqlclient 1.3.3 or newer is required; you have %s" % Database.__version__)
例如
启动后又报错
django.db.utils.InternalError: (1049, "Unknown database \'mysite2\'") 使用mysql数据库需要手动创建数据库
重启继续报错
AttributeError: \'str\' object has no attribute \'decode\'
顺着报错文件点进去,找到query = query.decode(errors=‘replace’)
将decode修改为encode即可
正常
继续报错

原因:django2.1 版本不再支持mysql5.5
