ruby-on-rails - rails capistrano 部署错误

Question

我已经用 gem capistrano 安装了 capistrano

在我的应用程序目录中，我安装了 cap install
此命令包括 deploy/production.rb和 deploy/staging.rb并在 config/deploy.rb
我的 production.rb文件有以下

set :stage, :production
role :all, %w{seting@mydomain.com}
server 'sub.mydomain.com', user: 'deploy', roles: %w{web app}, my_property: :my_value
set :ssh_options, { :forward_agent => true, :port => 1754, :keys => %w(/home/seting/.ssh/id_rsa) }

这是我的 deploy.rb

set :application, 'admin'
set :repo_url, 'git@bitbucket.org:username/myadmin.git'
namespace :deploy do

  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      # Your restart mechanism here, for example:
      # execute :touch, release_path.join('tmp/restart.txt')
    end
  end

  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
      # Here we can do anything such as:
      # within release_path do
      #   execute :rake, 'cache:clear'
      # end
    end
  end

  after :finishing, 'deploy:cleanup'

end

最后当我运行 cap production deploy
获取错误为

cap aborted!

此外，我没有在我的服务器中进行任何特殊安装来运行 Rails 应用程序。我决定首先将我的文件移动到服务器。方法对吗？

Answer 1

您应该设置角色名称 deploy 而不是设置或其他方式。

set :stage, :production
set :branch, 'master'
set :deploy_to, '/srv/www/server.com/'
role :all, %w{deploy@server.com}
server 'server.com', user: 'deploy', roles: %w{web app}, my_property: :my_value
fetch(:default_env).merge!(rails_env: :production)

这是 guide

你可能想跑

cap production deploy:check

检查您的配置。

在 capistrano 3.0 中也没有 deploy:setup
