一、将Django项目部署在Linux运行

报错：xadmin错误NameError:name 'reload' is not defined

ImportError: cannot import name 'smart_unicode'

xadmin的版本有问题，因为大量使用了python2的模块，但在python3已然放弃这些模块，直接用以下命令安装即可：
pip install https://github.com/sshwsfc/xadmin/tarball/master

二 python3 manage.py runserver warning

/usr/local/python3/lib/python3.6/site-packages/pymysql/cursors.py:170: Warning: (3090, "Changing sql mode 'NO_AUTO_CREATE_USER' is deprecated. It will be removed in a future release.")
  result = self._query(query)

修改项目setting的数据库设置，设置sql_mode=SET sql_mode='traditional'

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
'HOST': '',
'PORT': '3306',
'NAME': '',
'USER': '',
'PASSWORD': '',
'OPTIONS': {
'init_command': "SET sql_mode='traditional'",
},
    }
}
