当我部署rails项目时,Capistrano 3不会创建"当前"目录

Question

我正在尝试使用capistrano 3将我的ruby on rails 4项目部署到我的服务器中,但是我遇到了一些错误.

首先,当我这样做的时候

cap production deploy:check

一切看起来都好!但是,当我这样做

cap production deploy

我有两个错误:

DEBUG [e3cf53e3] Running [ -L /var/www/myapp/releases/20131026111326/public/assets ] on mydomain.com
DEBUG [e3cf53e3] Command: [ -L /var/www/myapp/releases/20131026111326/public/assets ]
DEBUG [e3cf53e3] Finished in 0.104 seconds with exit status 1 (failed).
DEBUG [304388e5] Running [ -d /var/www/myapp/releases/20131026111326/public/assets ] on mydomain.com
DEBUG [304388e5] Command: [ -d /var/www/myapp/releases/20131026111326/public/assets ]
DEBUG [304388e5] Finished in 0.104 seconds with exit status 1 (failed).

我得到的最后一个错误是:

DEBUG [4e4c65ef]    rake aborted!
DEBUG [4e4c65ef]    Unknown database 'myapp_production'

所以我认为我应该这样做

cap production deploy:migrate

但是我得到了一个不同的错误:当前目录不存在...

我很迷茫.我的配置文件是:

production.rb

set :stage, :production

role :all, %w{myuser@mydomain.com}

server 'mydomain.com', user: 'myuser', roles: %w{web app db}

  set :ssh_options, {
    keys: %w(/path/mykey.pem),
    forward_agent: true,
    auth_methods: %w(publickey)
  }

fetch(:default_env).merge!(rails_env: :production)

set :rvm_type, :user
set :rvm_ruby_version, 'ruby-2.0.0-p247'
 set :rake,           "rake" 
 set :rails_env,      "production" 
 set :migrate_env,    "" 
 set :migrate_target, :latest

Capfile

require 'capistrano/setup'

require 'capistrano/deploy'

require 'capistrano/rails'

require 'capistrano/rvm'

require 'capistrano/bundler'

Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r }

我在Gemfile中使用capistrano-bundler,capistrano-rvm和capistrano-rails

非常感谢你.

Capistrano无法为您创建数据库,current因为您没有完成部署,所以永远不会创建符号链接.

您看到的错误是因为数据库服务器上不存在数据库,它完全取决于您的服务器(postgresql,mysql等),但您需要进入数据库服务器并执行以下操作:

CREATE DATABASE myapp;
# Something else, too you'll need to GRANT permissions 
# in the sql server for your production database user, 
# or change the database ownership.

然后,您应该能够完成部署.
