问题描述
当我创建一个新用户,但它无法登录数据库时。
我这样做是这样的:
when i create a new user, but it cannot login the database.
I do that like this:
postgres@Aspire:/home/XXX$ createuser dev
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) y
Shall the new role be allowed to create more new roles? (y/n) y
然后创建一个数据库:
postgres@Aspire:/home/XXX$ createdb -O dev test_development
之后,我尝试 psql -U dev -W test_development
登录,但收到错误:
after that, I try psql -U dev -W test_development
to login, but get the error:
psql: FATAL: Peer authentication failed for user "dev"
$ b的对等身份验证失败$ b
我试图解决问题,但失败了。
I tried to solve the problem but failed.
推荐答案
尝试:
psql -U user_name -h 127.0.0.1 -d db_name
其中
-
-U
是数据库用户名 -
-h
是本地服务器的主机名/ IP,从而避免使用Unix域套接字 -
-d
是要连接到的数据库名称
-U
is the database user name-h
is the hostname/IP of the local server, thus avoiding Unix domain sockets-d
is the database name to connect to
然后进行评估作为Postgresql的网络连接,而不是Unix域套接字连接,因此不评估为您可能会在 pg_hba.conf
中看到本地连接:
This is then evaluated as a "network" connection by Postgresql rather than a Unix domain socket connection, thus not evaluated as a "local" connect as you might see in pg_hba.conf
:
local all all peer
