我正尝试通过关注this tutorial来kamal setup我的应用程序。
我设置了2个服务器（一个用于Ruby on Rails 7.1.2应用程序，一个用于MySQL 8.0.31数据库，都是Linux Ubuntu 23.10）和一个运行在Linode上的节点平衡器。
我的deploy.yml如下所示（我只是更改了敏感引用并删除了注解）：

service: my-app

image: myusername/my-app

servers:
  web:
    hosts:
      - 1.1.1.79

registry:
  username: myusername
  password:
    - KAMAL_REGISTRY_PASSWORD

env:
  clear:
    DB_HOST: 1.1.1.172
  secret:
    - RAILS_MASTER_KEY
    - MYSQL_ROOT_PASSWORD

accessories:
  db:
    image: mysql:8.0
    host: 1.1.1.172
    port: 3306
    env:
      clear:
        MYSQL_ROOT_HOST: '%'
      secret:
        - MYSQL_ROOT_PASSWORD
    files:
      # - config/mysql/production.cnf:/etc/mysql/my.cnf
      - db/production.sql:/docker-entrypoint-initdb.d/setup.sql
    directories:
      - data:/var/lib/mysql

字符串
我的Dockerfile如下所示（敏感引用已更改）：

ARG RUBY_VERSION=3.2.2

在.env档案中，我已经：

KAMAL_REGISTRY_PASSWORD=secret_kamal_password
RAILS_MASTER_KEY=secret_master_key
MYSQL_ROOT_PASSWORD=<%= ENV['MYSQL_ROOT_PASSWORD'] %>

# Note: `ENV['MYSQL_ROOT_PASSWORD']` comes from setting environment variables using credentials (see https://dev.to/dalezak/rails-environment-variables-using-credentials-mh7)
# I also tried the following without success (please read bottom notes):
# MYSQL_ROOT_PASSWORD=secret_mysql_password (an explicit password)
# MYSQL_ROOT_PASSWORD=

型
在config/database.yml文件中，我已经：

default: &default
  adapter: mysql2
  encoding: utf8mb4
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
  username: root
  password:
  socket: /tmp/mysql.sock
  variables:
    sql_mode: TRADITIONAL

# ...

production:
  <<: *default
  host: <%= ENV["DB_HOST"] %>
  database: my_app_production
  username: root
  password: <%= ENV['MYSQL_ROOT_PASSWORD'] %>
  adapter: mysql2
  encoding: utf8mb4
  reconnect: false
  socket: /var/run/mysqld/mysqld.sock
  variables:
    sql_mode: TRADITIONAL

型
我还设置了路线get 'up' => 'rails/health#show', :as => :rails_health_check，和许多其他的东西，在应用程序和服务器上...请，要求更多的信息。
现在，我觉得我在看到我的应用程序终于部署接近设置结束.🦾💪
当我在控制台中运行kamal setup时，我会得到：

与MySQL用户名/密码相关的代码有什么问题？
注：

  • 即使我使用MYSQL_ROOT_PASSWORD=secret_mysql_password这样的显式密码，也会出现同样的错误。
  • 我很失望，错误似乎发生在服务器1.1.1.79上，而不是数据库服务器上。数据库服务器位于1.1.1.172
  • 请注意，默认情况下，MySQL 8在初始化时不再像以前的版本那样设置密码。然而，即使我根本不设置密码，日志中的不同之处在于，它输出“Mysql 2：：Error：：ConnectionError：Access denied for user 'root'@'1.1.1.79'（using password：NO）"。

该如何解决问题？

尝试将DB_HOST放入.env文件，然后执行kamal env push
