【问题描述】：
我将来自不同 conf 文件的 mySql 凭据提供给 django 项目。 之前它工作正常，但现在我重新安装了我的 ubuntu 后它停止工作了。
settings.py：
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'OPTIONS': {
'read_default_file': './connection.cnf',
}
}
}
connection.cnf：
[client]
database=test
user=root
password=rajiv@123
HOST=localhost
PORT=3306
default-charset=utf8
另外，conf文件的位置如下：
rajiv@ubuntu:~/djangoProjects/test$ ls -l
total 9
drwxrwxrwx 1 root root 4096 Dec 28 11:04 test
drwxrwxrwx 1 root root 4096 Dec 27 14:00 testApp
-rwxrwxrwx 1 root root 103 Dec 3 00:37 connection.cnf
-rwxrwxrwx 1 root root 252 Oct 15 11:36 manage.py
给出的错误如下：
rajiv@ubuntu:~/djangoProjects/test$ python manage.py runserver
Performing system checks...

无法弄清楚为什么会出错。 如果有什么问题，谁能建议一些其他的方法。

将其更改为标准方法，工作正常： DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'test', 'USER' : 'root', '密码': 'rajiv@123', } }
