Postgresql :无法与新创建的用户连接



这是错误:

$  psql -h localhost -U kMbjQ6pR9G  -d fzvqFILx0d
Password for user kMbjQ6pR9G: 
psql: FATAL:  password authentication failed for user "kMbjQ6pR9G"
FATAL:  password authentication failed for user "kMbjQ6pR9G"

我可能缺少使用新PostgreSQL的配置步骤。

这是我尝试使用自己的数据库创建新用户的命令行:

sudo -u postgres bash -c "psql -c "CREATE USER $USER WITH PASSWORD '$PASSWORD';"" &&
sudo -u postgres bash -c "psql -c "CREATE DATABASE $DB;"" &&
sudo -u postgres bash -c "psql -c "GRANT ALL PRIVILEGES ON DATABASE $DB to $USER;"" &&

这是PostgreSQL配置:

$ sudo grep -v ^# /etc/postgresql/9.5/main/pg_hba.conf  |grep -v ^$
local   all             postgres                                md5
local   all             all                                     md5
host    all             all             127.0.0.1/32            md5
host    all             all             ::1/128                 md5

这是我创建的所有测试

$ sudo  -u postgres bash -c 'psql -c "select * from pg_shadow;"'

我认为这很简单,但我错过了这一点。

感谢您的支持,大卫。

尝试连接时是否显式指定了数据库?

psql -h localhost -U myuser -d mydb

这就是我通常如何设置用户以完全拥有给定的数据库:

create role myuser with createdb login encrypted password 'mypassword';
create database mydb with owner 'myuser' encoding 'utf8';
pg_hba.conf:
local   myuser           mydb                                  md5
...

问题很明显:用户名和数据库名称是小写的!

这是我用来创建用户和他自己的数据库的脚本:

#!/bin/bash
if [ -n "$1" ]; then
    DB="$1"
else
    DB=$(php -r "echo substr(str_shuffle(str_repeat('abcdefghijklmnopqrstuvwxyz', ceil(10/63) )),1,10);")
fi
USER=$(php -r "echo substr(str_shuffle(str_repeat('abcdefghijklmnopqrstuvwxyz', ceil(10/63) )),1,10);")
PASSWORD=$(php -r "echo substr(str_shuffle(str_repeat('0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ', ceil(20/63) )),1,20);")
sudo -u postgres psql -c "CREATE USER $USER WITH PASSWORD '$PASSWORD';"
sudo -u postgres psql -c "CREATE DATABASE $DB;"
sudo -u postgres psql -c "GRANT ALL PRIVILEGES ON DATABASE $DB to $USER;"
cat << EndOfMessage
POSTGRESQL_ADDON_DB="$DB"
POSTGRESQL_ADDON_HOST="localhost"
POSTGRESQL_ADDON_PASSWORD="$PASSWORD"
POSTGRESQL_ADDON_PORT="5432"
POSTGRESQL_ADDON_USER="$USER"
EndOfMessage
