Question

我在安装和配置了postgresql的地方有一个Ubuntu 18.04 LTS vps。我可以通过命令行登录到PostgreSQL。但是我无法建立与项目的连接。

但是在部署Adonis项目后，我立即看到以下错误消息 error: error: password authentication failed for user "postgres"

完全错误如下：

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

尽管我进行了一些研究，但按照这些说明，我更新了pg_hba.conf文件。在下面：

# 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environemnt（.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。

有人可以帮我弄清楚哪里出了问题吗？

Answer 1

我刚刚改变了这个

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为什么但是值被改变了。

Answer 2

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

password: "direct set your password",

并尝试在Cpanel托管中遇到相同的问题，并且尝试使用此方法

Postgresql错误：错误：Adonis.js中的用户“ postgres”的密码身份验证失败
