无法连接到PostgreSQL服务器:FATAL:用户“postgres”的对等验证失败
问题描述:
如何从adminer访问postgres数据库?无法连接到PostgreSQL服务器:FATAL:用户“postgres”的对等验证失败
我已经为用户postgres
更改密码:
$ sudo -u postgres psql
$ postgres=# alter user postgres password 'secret';
结果:
ALTER ROLE
但是我还是对adminer此错误:
Unable to connect to PostgreSQL server: FATAL: Peer authentication failed for user "postgres"
任何想法为什么?
我有这两个用户:
postgres=# \du
List of roles
Role name | Attributes | Member of
-----------+------------------------------------------------------------+-----------
postgres | Superuser, Create role, Create DB, Replication, Bypass RLS | {}
root | Superuser, Create role, Create DB | {}
但我并没有为用户root
设置密码时,我该命令创建它:
sudo -u postgres createuser --interactive
输出(为什么没有问密码:):
Enter name of role to add: root
Shall the new role be a superuser? (y/n) y
但我仍然得到adminer错误:
Unable to connect to PostgreSQL server: FATAL: Peer authentication failed for user "root"
编辑:
这是我pg_hba.conf
sudo nano /etc/postgresql/9.5/main/pg_hba.conf
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all peer
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all ::1/128 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres peer
#host replication postgres 127.0.0.1/32 md5
#host replication postgres ::1/128 md5
我改变peer
到ident
一些位:
# Database administrative login by Unix domain socket
local all postgres ident
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all ident
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all ::1/128 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres peer
#host replication postgres 127.0.0.1/32 md5
#host replication postgres ::1/128 md5
然后重新启动我的机器。但仍然没有运气。
答
看起来您正在使用“同等身份验证”,您希望使用“密码验证”。使用默认的pg_hba.conf,您可以通过指定主机名或“127.0.0.1”切换到密码验证。
