我是 Rails 的初学者。我想在 heroku.com 上部署我的项目。我使用 Sqlite，但 heroku 不支持它。所以，我尝试将我的项目转移到 MySQL。我做了这个说明：Convert a Ruby on Rails app from sqlite to MySQL?

但是，heroku 是这样说的：我们很抱歉，但出了点问题。你能帮助我吗？

这是我的宝石文件：

source 'https://rubygems.org'

gem 'pg'
gem 'rails', '3.2.12'
gem 'gravatar_image_tag', '1.0.0.pre2'
gem "will_paginate", :git => "https://github.com/p7r/will_paginate.git", :branch => "rails3"
gem 'yaml_db', :git => 'git://github.com/ludicast/yaml_db.git'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

group :development, :test do
  gem 'faker', '0.3.1'
  gem 'sqlite3-ruby', :require => 'sqlite3'
end

group :production do
    gem "mysql2", "~> 0.3.11"
end

group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'


  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

group :test do
  gem 'rspec-rails', '2.6.1'
  gem 'webrat', '0.7.1'
end

这是我的 database.yml 文件：

development:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: myapp_development
  pool: 5
  username: root
  password: "0761"
test:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: myapp_test
  pool: 5
  username: root
  password: "0761"

production:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: myapp_production
  pool: 5
  username: root
  password: "0761"

这是我的日志：

更新 我只能使用 MySQL。我的项目是测试我正在寻找的一家公司的实习任务。他们说我在项目中使用 MySql。

Heroku 真正设计为运行 PostgreSQL 作为其数据库引擎，而不是 MySQL。您实际上已经安装了 postgresql gem ( pg)。您收到的错误与访问数据库（特别是users表）有关。

虽然可以作为新用户在 Heroku 上运行 MySQL，但我建议只使用 postgresql，因为它更容易设置，您不必担心安装额外的附加组件来使其工作。

你在哪里托管你的 MySQL 数据库？ 确保您的数据库服务器允许从 Heroku 进行远程访问。正确设置后，亚马逊 (AWS) 是最佳解决方案。

如果您在本地计算机上托管 MySQL 数据库以进行生产，那么您需要确保 Heroku 的服务器可以远程访问您的计算机以进行生产。

在您的 Gemfile 中删除这些行并替换为下面的示例。

  • gem 'pg'
  • gem 'sqlite3-ruby', :require => 'sqlite3'
  • gem "mysql2", "~> 0.3.11"

我也强烈建议查看https://github.com/laserlemon/figaro和http://railscasts.com/episodes/85-yaml-configuration-revised?view=comments

在 AWS 上设置 MySQL：

  1. 使用正确的数据库 gem 更新 Gemfile
  2. 更新 database.yml 连接设置
  3. 安装 Heroku 工具带https://toolbelt.heroku.com/
  4. 注册 AWS 托管的 MySQL http://aws.amazon.com/rds/
  5. Amazon 要求您从本地计算机的 WAN IP 授予访问权限，并且您还需要授予 Heroku 的应用程序服务器授权访问权限以进行生产。
    • 通过以下方式登录 AWShttp://console.aws.amazon.com/
    • 转到“服务”>“RDS”
    • 在左侧菜单“导航/数据库”>“数据库安全组”>“默认”下
    • 添加 CIDR/IP：#.#.#.#（您的本地 pc ip http://www.whatsmyip.us/）
    • 添加 EC2 安全组（这是 heroku aws id）
      • aws 帐户 ID：“098166147350”
      • ec2 安全组：“默认”
  6. 在 Heroku 上设置 AWS RDS MySQL 数据库
    • 确认 Heroku 被授予 AWS RDS 远程访问权限
      • $ cd myAppDir
      • $ heroku login
      • $ heroku config:get DATABASE_URL
      • $ heroku addons:add amazon_rds url=mysql2://masteruser:pass@dbinstance.123endpoint321.amazonaws.com/databasename
      • $ heroku config:get DATABASE_URL
      • 确认新的数据库设置

Gemfile ~ 不要忘记$ bundle install&$ bundle update

你有这个应用程序的 mysql 插件吗？

Heroku 默认为您提供 Postgres 数据库，但如果您想使用另一种数据库类型，即 mysql，则需要使用插件。我不确定插件中可能有免费的解决方案。

当您将应用程序部署到 Heroku 时，它们会覆盖您的 database.yml 文件，将其指向正确的数据库 url。

首先 heroku 为您的应用程序提供 PostgreSQL 数据库，编辑您的 Gemfile

并添加 gem 'pg'

它也使用瘦作为服务器，所以添加

宝石“薄”

将您的 Database.yml 更改为所有环境

adapter: PostgreSQL
  encoding: utf8
  reconnect: false
  database: myapp_production
  pool: 5
  username: root
  password: "0761"

从生产环境中删除 mysql gem。Heroku 不支持 sqlite 数据库。在生产中使用 postgres。您的 gemfile 应如下所示：

group :production do
  gem "pg" # move your pg gem inside here
end

group :development, :test do
  gem "sqlite3"
end

更改您的 gemfile 以反映上述内容，$ bundle然后运行捆绑新的 gem，添加并提交您的更改并将它们推送到 heroku。

这将允许您在开发和测试中使用 sqlite，在生产中使用 postgresql，这是 heroku 所需要的。
