如何在potgresql中启动GSSAPI

纳瓦尼塔·克里希南

我在 REDHAT 7 中安装了 postgres。然后我安装了 python 3.6。我已经创建了虚拟环境。我也在 postgres 中创建了一个表。然后我执行了这个 python 脚本，但出现了一些错误。

import psycopg2
conn = psycopg2.connect("dbname=postgres user=postgres host=localhost password=postgres")

错误是：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/data/scripts/san-automation/lib/python3.7/site-packages/psycopg2/__init__.py", line 126, in connect
    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
psycopg2.OperationalError: could not initiate GSSAPI security context: Unspecified GSS failure.  Minor code may provide more information
could not initiate GSSAPI security context: Server not found in Kerberos database
FATAL:  Ident authentication failed for user "postgres"

cat /var/lib/pgsql/12/data/pg_hba.conf

看起来它正在抢先加载您的 gss/kerberos 配置文件（即使它不会使用它们），并在其中找到了它不喜欢的东西。但这似乎只是一个警告。真正的错误是最后一行：
