连接到“localhost”（127.0.0.1）的服务器，端口 5432 失败：致命：用户“postgres”的身份验证失败

Question

我正在尝试在 Django 应用程序中设置 Django PostgreSQL。我为该用户创建了数据库、用户和密码，当我运行

\l

时，我可以看到该数据库。当我使用

python manage.py runserver

运行 django 应用程序时，我收到以下错误消息。

ON PURE START UP
USER TABLE NOT EXIST
connection to server at "localhost" (127.0.0.1), port 5432 failed: could not initiate GSSAPI security context: Unspecified GSS failure.  Minor code may provide more information: Server not found in Kerberos database
connection to server at "localhost" (127.0.0.1), port 5432 failed: FATAL:  Ident authentication failed for user "postgres"

我错过了什么

Answer 1

类似的错误，但 php 应用程序从 docker 容器连接到本地主机上的 PostgreSQL

FastCGI sent in stderr: "PHP message: PHP Warning:  pg_connect(): Unable to connect to PostgreSQL server: connection to server at "127.0.0.1", port 5432 failed: FATAL:  Ident authentication failed for user

正如@jjanes 在评论中所写

sudo vim /var/lib/pgsql/data/pg_hba.conf

将

ident

更改为

md5

以进行密码验证

# host          DATABASE  USER  ADDRESS  METHOD  [OPTIONS]

host    all       all        127.0.0.1/32            md5

需要重启

sudo systemctl restart postgresql
