postgresql - Phoenix 无法连接到 Heroku 的 PostgreSQL 服务器

Question

这是我在设置为乱七八糟的原始 Phoenix 应用程序上看到的错误:

[error] Postgrex.Protocol (#PID<0.362.0>) failed to connect: ** (Postgrex.Error) FATAL 28000 (invalid_authorization_specification): no pg_hba.conf entry for host "24.25.201.68", user "koilqmnaakvfjg", database "dc245o0vlbprf7", SSL off

这是我的config/dev.exs:

# Configure your database
config :hello, Hello.Repo,
  adapter: Ecto.Adapters.Postgres,
  username: "koilqmnaakvfjg",
  password: "somepass",
  database: "dc245o0vlbprf7",
  hostname: "ec2-54-243-54-6.compute-1.amazonaws.com",
  pool_size: 10

我缺少一些简单的东西？

编辑:

我的 pg_hba.conf 文件如下所示:

# TYPE  DATABASE        USER            ADDRESS                 METHOD
host  all  all 0.0.0.0/0 md5
# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all                                     trust
host    replication     all             127.0.0.1/32            trust
host    replication     all             ::1/128                 trust

Answer 1

您需要将 ssl 参数设置为 true，如果问题仍然存在，请修改 pg_hba.conf 文件。

解决方法:

# Configure your database
config :hello, Hello.Repo,
  adapter: Ecto.Adapters.Postgres,
  username: "koilqmnaakvfjg",
  password: "somepass",
  database: "dc245o0vlbprf7",
  hostname: "ec2-54-243-54-6.compute-1.amazonaws.com",
  pool_size: 10,
  ssl: true

希望对你有帮助:D
