帽部署：冷生產數據庫沒有配置 - Postgresql

Question

我想運行帽部署：冷安裝與postgresql的rails應用程序，我找不出'生產數據庫沒有配置'或其他任何意思。

Answer 1

錯誤信息手段你沒有在你的database.yml中配置你的生產數據庫。

在遠程服務器上查看您的database.yml。

應該類似於此：

production: 
    adapter: mysql2 
    encoding: utf8 
    reconnect: false 
    database: database_name 
    pool: 5 
    username: database_user 
    password: th3p4ssw0rd 
    socket: /path/to/mysql.sock 

我建議做到以下幾點：

1）請勿將database.yml下的版本控制。 使用git時，只需將/config/database.yml添加到.gitignore文件（或創建該文件）並提交它。

2.）在shared/config/（通過腳本或手動）在遠程服務器上創建database.yml。

3.）在部署時將database.yml從應用符號鏈接到shared/config。

# /config/deploy.rb: 
after 'deploy:finalize_update', 'db:symlink' 

namespace :db do 
    desc "Symlinks the database.yml" 
    task :symlink, :except => { :no_release => true }, :roles => :app do 
    run "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml" 
    end 
end
