Postgresql 错误：错误：Adonis.js 中用户“postgres”的密码验证失败

Question

我有一个 Ubuntu 18.04 LTS vps，我在其中安装和配置了 postgresql。 我可以通过命令行登录到 postgresql。但我无法与我的项目建立连接。

但是在部署了一个 Adonis 项目之后，它给我带来了下面的错误消息 error: error: password authentication failed for user "postgres"

完整错误如下：

error: error: password authentication failed for user "postgres"

虽然我做了一些研究并按照这些说明更新了pg_hba.conf 文件。如下：

# Database administrative login by Unix domain socket
local   all             postgres                                peer

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     md5
# IPv4 local connections:
host    all             all             127.0.0.1/32            peer
# IPv6 local connections:
host    all             all             ::1/128                 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all                                     peer
host    replication     all             127.0.0.1/32            md5
host    replication     all             ::1/128                 md5

这是我的项目环境（.env）文件

HOST=127.0.0.1
PORT=8989
NODE_ENV=development

APP_NAME=
APP_URL=http://${HOST}:${PORT}
CACHE_VIEWS=false
APP_KEY=my_app_key

DB_CONNECTION=pg
DB_HOST=127.0.0.1
DB_PORT=5432
DB_USERNAME=postgres
DB_PASSWORD=my_db_pass
DB_DATABASE=my_db_name

... other credential goes here ....

注意：my_db_pass 是我的 postgres 用户名的密码。我可以在命令行中使用此密码成功登录。

谁能帮我弄清楚出了什么问题？

Answer 1

我刚刚改了这个

let client = new Client({
  user: process.env.USER,
  host: process.env.HOST,
  database: process.env.DATABASE,
  password: process.env.PASSWORD,
  port: process.env.DB_PORT,
});

到这里

let client = new Client({
  user: "postgres",
  host: process.env.HOST,
  database: process.env.DATABASE,
  password: "aaaaa",
  port: process.env.DB_PORT,
});

在服务器中，process.env.USER 不是我给定的用户名。 IDK 为什么，但值已更改。

Answer 2

我遇到了同样的问题。就我而言，我在密码中添加了特殊字符并转义它们。

Answer 3

进入 config/database.js
找到 PostgreSQL 配置并像这样替换密码值

password: "direct set your password",

并尝试我在 Cpanel 托管中遇到同样的问题，我尝试这种方法它的工作
