Postgresql Postgres群集：用户的密码身份验证失败“；博士后&x201D；

在我的Postgres中，服务器使用命令pg_createcluster在端口5433上侦听创建了一个集群。要为用户postgres设置密码，我遵循以下步骤：

编辑文件nano/etc/postgresql/9.3//pg_hba.conf

换线

托管所有127.0.0.1/32 md5

排队

托管所有127.0.0.1/32信任

使用以下命令更改密码

sudo-u postgres psql-h localhost-p 5433

postgres=#\password postgres

输入新密码：

# nano /etc/postgresql/9.3/<instance_name>/pg_hba.conf
# /etc/init.d/postgresql restart
# su - postgres
$ psql -U postgres -p 5433 -h localhost
Password for user postgres:

# TYPE  DATABASE        USER            ADDRESS                 METHOD
# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust

# nano /etc/postgresql/9.3/<instance_name>/pg_hba.conf
# /etc/init.d/postgresql restart
# su - postgres
$ psql -U postgres -p 5433 -h localhost
postgres=# \password postgres
Enter new password:
Enter it again:
postgres=# \q
$ exit
# nano /etc/postgresql/9.3/<instance_name>/pg_hba.conf
# /etc/init.d/postgresql restart

请重新输入：

postgres=#\q

编辑文件nano/etc/postgresql/9.3//pg_hba.conf

换线

托管所有127.0.0.1/32信任

排队

托管所有127.0.0.1/32 md5

显示无错误，但连接控制台和pgadmin3会触发错误：用户“postgres”的密码验证失败。默认情况下，在实例（main）中使用相同的进程，我可以成功连接

我感谢任何帮助，因为我没有找到太多的文档来处理Postgres实例。

提前感谢。

首先，您需要重新加载配置，以便应用所有更改。连接端口可能未打开，而且您还没有清楚地共享

本地连接的配置。这应该很好：

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5

谢谢你的回复。我在pg_hba.conf中看到了您的响应配置：

# TYPE  DATABASE        USER            ADDRESS                 METHOD
# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5

更改密码：

# nano /etc/postgresql/9.3/<instance_name>/pg_hba.conf
# /etc/init.d/postgresql restart
# su - postgres
$ psql -U postgres -p 5433 -h localhost
Password for user postgres:

# IPv4 local connections:
host    all             all             127.0.0.1/32            trust

# nano /etc/postgresql/9.3/<instance_name>/pg_hba.conf
# /etc/init.d/postgresql restart
# su - postgres
$ psql -U postgres -p 5433 -h localhost
postgres=# \password postgres
Enter new password:
Enter it again:
postgres=# \q
$ exit
# nano /etc/postgresql/9.3/<instance_name>/pg_hba.conf
# /etc/init.d/postgresql restart

更改密码：
