我有一个在 Windows 机器上运行的机器人,最近我买了一个 Ubuntu 虚拟服务器。在经历了一系列类似无限的错误之后,我完全重置了服务器并从头开始重试。您可以在此处查看我之前的一些错误的另一篇文章:https://stackoverflow.com/questions/63310926/no-pg-hba-conf-entry-for-host-connect-call-failed-invalid-data-directory-for?noredirect=1#comment111984138_63310926
所以现在当我尝试启动我的机器人时,它给了我这个错误:
Traceback (most recent call last):
File "bot.py", line 950, in <module>
bot.loop.run_until_complete(create_db_pool())
File "/usr/lib/python3.8/asyncio/base_events.py", line 616, in run_until_complete
return future.result()

File "/usr/lib/python3.8/asyncio/tasks.py", line 483, in wait_for
return fut.result()
asyncpg.exceptions.InvalidAuthorizationSpecificationError: Peer authentication failed for user "postgres"
但数据库、用户和密码都是正确的。它现在仍在运行,因为机器人正在我的 Windows 机器上运行,这就是为什么我认为这是 Ubuntu 特有的问题。我的监听地址设置为“
listen_addresses = '*'
并且我的 pg_hba.conf 设置为:
# TYPE DATABASE USER ADDRESS METHOD
# IPv4 local connections:
host all all 0.0.0.0/0 md5
# IPv6 local connections:
host all all ::/0 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
host replication all 0.0.0.0/0 md5
host replication all ::/0 md5
它曾经有默认 IP,但我尝试使用密码打开它以进行任何连接,但 Ubuntu 服务器仍然无法连接到它。另外,目前我的 Ubuntu 系统上似乎没有这个文件。我可以从我的 Windows 机器上编辑它,但我不知道这是否会影响两者。我不完全了解数据库,但我很确定它由我自己的 PC 托管?我也可以将文件本身手动带到 Ubuntu 服务器,但我不想再把事情搞砸,甚至陷入更困境。更改host
为local
似乎只会使数据库在我的 Windows 机器上停止工作。
我被这个问题困扰了很长时间,不知道该怎么办。我真的希望有人知道这个问题,希望我已经提供了足够的信息。谢谢。
