密码正确但是oracle验证失败,psycopg2.operational错误：致命：用户“的密码验证失败”...
我对网络开发还很陌生。
首先，我在我的vps(Ubuntu 16.04)上部署了一个静态网站，没有问题，然后我试图添加一个博客应用程序。
它在本地与PostgreSQL很好地工作，但我不能让它在我的服务器上工作。
它似乎试图与我的Unix用户连接到Postgres。
为什么我的服务器要这么做？
我确实通过postgres用户创建了一个数据库和一个所有者，匹配settings.py中的登录信息，我希望psycopg2尝试使用这些登录信息连接到数据库：
Settings.py+python解耦：DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': config ('NAME'),
'USER': config ('USER'),
'PASSWORD': config ('PASSWORD'),
'HOST': 'localhost',
'PORT': '',
}
}
这是每次尝试./manage.py migrate时收到的错误消息
“myportfolio”是我的Unix用户名，数据库用户名不同：Traceback (most recent call last):

我试着：删除我的django代码，重新安装
删除/清除postgres并重新安装
将pg_hba.conf local修改为信任
有一次，我创建了一个名为“myportfolio”的django超级用户作为我的unix用户：这会产生问题吗？
