Rails - Mina - 无法在database.yml文件中加载环境变量

Question

Mina无法加载database.yml文件中的环境变量,如下所述:

deploy.rb:

task :deploy => :environment do
  deploy do
    # Put things that will set up an empty directory into a fully set-up
    # instance of your project.
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:db_migrate'
    queue! "#{rake} db:seed"
    invoke :'rails:assets_precompile'
    invoke :'deploy:cleanup'
  end
end

vim~/.bash_profile:

export MYSQLUSERNAME=mysql_user_name
export MYSQLPASSWORD=mysql_password

database.yml的:

production:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: my_db_name
  pool: 5
  username: <%= ENV['MYSQLUSERNAME'] %>
  password: <%= ENV['MYSQLPASSWORD'] %>

错误:

$ mina deploy
  .....
  .......
  -----> DB migrations unchanged; skipping DB migration
         $ RAILS_ENV="production" bundle exec rake db:seed
         rake aborted!
         Mysql2::Error: Access denied for user 'root'@'localhost' (using password: NO)
               /home/user_name/.rvm/gems/ruby-2.0.0-p247/gems/mysql2-0.3.16/lib/mysql2/client.rb:70:in `connect'

注意:如果我在database.yml文件中替换username(mysql_user_name)和密码(mysql_user_name)值而不是<%= ENV ['MYSQLUSERNAME']%>和<%= ENV ['MYSQLPASSWORD']%>,则效果很好.

任何人都可以请帮助我,我可以在部署使用Mina时在*.yml文件中加载ENV变量.

谢谢!

您需要将 ENV 放入 .bashrc 文件中。.bash_profile 未加载，因为 mina 使用非交互式 shell。
