ruby-on-rails - Rails 5.2 与 master.key Digital Ocean 部署:ActiveSupport::MessageEncryptor::InvalidMessage:ActiveSupport::MessageEncryptor::InvalidMessage

Question

我已将 Ruby on Rails 应用程序从 Rails 5.1.2 迁移到 Rails 5.2.0 以使用加密的 secret 。应用程序已成功部署到 Digital Ocean Ubuntu 服务器。但是当我进入浏览器访问时，它显示以下日志。

    ActiveSupport::MessageEncryptor::InvalidMessage: ActiveSupport::MessageEncryptor::InvalidMessage
  /home/deploy/apps/GeekyCricket/shared/bundle/ruby/2.4.0/gems/activesupport-5.2.0/lib/active_support/message_encryptor.rb:206:in `rescue in _decrypt'

  (erb):12:in `<main>'

我使用 railscredentials:edit 添加了加密 key ，这会创建 config/credentials.yml.enc 和 master.key。

我还在我的 ubuntu 服务器上的 /app_name/shared/config/ 上添加了 master.key 文件，还放置了一个环境变量 RAILS_MASTER_KEY。但仍然收到此错误，我不知道我在这里缺少什么。

Answer 1

解决方案 A 和 B 是不同的解决方案。只需选择对您有利的即可。

a.从持续集成部署

1.编辑deploy.rb

set :default_env, {
  "RAILS_ENV" => "production",
  "RAILS_MASTER_KEY" => ENV["RAILS_MASTER_KEY"]
}

2.添加RAILS_MASTER_KEY作为变量

• Travis CI
• GitLab CI

b. master.key的使用

1.编辑deploy.rb

append :linked_files, "config/master.key"

2.上传master.key与 :linked_files

假设我们的应用程序的根路径是 /home/deploy/awesome-project 。我们需要做的就是将 key 文件上传到/home/deploy/awesome-project/shared/config/master.key .
