无法登录PostgreSQL数据库 [英] Can't log into PostgreSQL database

问题描述

我这样创建了一个用户：

I created a user like this:

create user blog with password 'blog';

然后我将其设为数据库的所有者：

Then I made it the owner of a database:

alter database blog_development owner to blog;

然后我尝试登录，但没有成功：

Then I tried to log in and it didn't work:

$ psql -d blog_development -U blog -W
Password for user blog:
psql: FATAL:  Ident authentication failed for user "blog"

知道为什么吗？

一个我尝试过的事情是编辑 pg_hba.conf

One thing I've tried is editing pg_hba.conf

 76 # Database administrative login by UNIX sockets
 77 local   all                postgres                          ident
 78
 79 # TYPE  DATABASE           USER        CIDR-ADDRESS          METHOD
 80
 81 # "local" is for Unix domain socket connections only
 82 local   all                all                               ident
 83 # IPv4 local connections:
 84 host    all                all         127.0.0.1/32          md5
 85 host    blog_development   blog        127.0.0.1/32          md5
 86 # IPv6 local connections:
 87 host    all                all         ::1/128               md5

第85行是我添加的。在那之后我重新启动了PostgreSQL，但是它似乎没有任何改变。

Line 85 is the one I added. I restarted PostgreSQL after that but it didn't seem to change anything.

推荐答案

我只是试图以错误的方式进行连接。这是正确的方法：

I was just trying to connect in the wrong way. Here's the right way:

psql -h localhost -U blog -d blog_development
