【问题描述】:
近一个月来,我一直在努力解决这个问题。每当我尝试在生产中访问我的 Django Admin 页面时,都会收到以下错误:
OperationalError at /admin/login/
FATAL: password authentication failed for user "vpusr"
FATAL: password authentication failed for user "vpusr"
我的production.py设置文件如下:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'vpdb',
'USER': 'vpusr',
'PASSWORD': os.environ["VP_DB_PASS"],
'HOST': 'localhost',
}
}
注意:环境变量工作正常。即使我把普通密码硬编码在那里也不起作用。
这是数据库列表及其所有者:
List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges
-----------+----------+----------+-------------+-------------+-----------------------
postgres | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
template0 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres +
| | | | | postgres=CTc/postgres
template1 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres +
| | | | | postgres=CTc/postgres
vpdb | vpusr | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =Tc/vpusr +
| | | | | vpusr=CTc/vpusr
这是用户列表:
List of roles
Role name | Attributes | Member of
-----------+------------------------------------------------------------+-----------
postgres | Superuser, Create role, Create DB, Replication, Bypass RLS | {}
vpusr | Superuser, Create DB | {}
如您所见,我也尝试将超级用户和创建数据库的角色添加到 vpusr,但没有任何效果。
即使我尝试像这样通过终端进行连接,我也会遇到同样的错误:
sudo -u postgres psql -U vpusr vpdb
我仍然收到错误:psql: FATAL: Peer authentication failed for user "vpusr"
当我执行这个命令时:
psql -U vpusr -h localhost vpdb
我以 vpusr 正确连接到 psql。
还有一些注意事项: 我确实删除了数据库和用户并重新创建了它们。我确保密码正确。 我在 Digital Ocean 的 Ubuntu 服务器上使用 Gunicorn、Nginx、Virtualenv、Django、Postgres。
提前感谢您抽出宝贵时间阅读本文并帮助我!
编辑: 我注意到我的应用迁移文件夹中没有迁移!会不会是django或者我的用户或者postgres没有写文件的权限?
编辑:注意:我将用户更改为 TONY 在我的 postgres 日志文件中发现以下错误:

编辑:
pg_hba.conf 文件:
# Database administrative login by Unix domain socket
local all postgres peer
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all peer
# IPv4 local connections:
host all all 127.0.0.1/32 password
# IPv6 local connections:
host all all ::1/128 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres peer
#host replication postgres 127.0.0.1/32 md5
#host replication postgres ::1/128 md5
你能从中看出什么?
【问题讨论】:
-
当您尝试通过终端连接时,它使用了对等身份验证,正如您在错误中看到的那样。使用:
psql -U vpusr -h localhost vpdb. -
@PauloAlmeida 似乎有效。它要求输入 vpusr 密码,当我正确输入时,它会以 vpusr 的形式打开 psql
-
好的,所以问题是另一个问题,因为我建议的命令是 Django 应该尝试做的,因为您的设置中的
HOST是localhost。我不明白它可能是什么。 -
每当 Django 尝试连接到数据库时,
/var/log/postgresql中的日志文件中应该添加一行或多行。你能显示这些线条吗? -
@antonischristofides 我有一个包含多个文件的 postgresql 文件夹: postgresql-9.5-main.log postgresql-9.5-main.log.4.gz postgresql-9.5-main.log.1 postgresql-9.5- main.log.5.gz
