ruby-on-rails - Capistrano 部署后 Rails Assets 未编译

Question

我正在使用 Capistrano 部署我的 Rails 应用程序，似乎 Assets 没有被编译，除非我 ssh 进入服务器并手动运行 RAILS_ENV=development bundle exec rake assets:precompile。

我已尝试按照 the capistrano/rails github page 上的说明进行操作，但我不确定我是否遗漏了什么。

运行 cap production deploy 成功完成。但我不知道如何检查 assets:precompile 任务是否实际运行。运行 cap production deploy:assets:precompile 也成功完成，但服务器上没有明显变化。

版本

Server version: Apache/2.4.7 (Ubuntu)
Phusion Passenger 5.0.22
ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux]
Rails 4.2.5

capistrano (3.1.0)
capistrano-bundler (1.1.4)
capistrano-rails (1.1.6)
capistrano-rbenv (2.0.4)

Capfile

require 'capistrano/setup'
require 'capistrano/deploy'

require 'capistrano/rbenv'
require 'capistrano/rails/assets'

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

config/deploy.rb

set :application, "website"
set :repo_url, "git@bitbucket.org:company/website.git"
set :deploy_to, "/var/www/#{fetch(:application)}"
set :user, "webmaster"

set :rbenv_path, '/home/webmaster/.rbenv'
set :rbenv_ruby, '2.2.3'

set :assets_roles, [:web, :app]
set :keep_assets, 2

set :linked_dirs, fetch(:linked_dirs, []).push('log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system', 'public/uploads')
set :linked_files, fetch(:linked_files, []).push('config/database.yml', 'config/secrets.yml')

config/deploy/production.rb

set :stage, :production

server 'company.com', user: 'webmaster', roles: %{web app db}

关于 Assets 未编译的任何想法？

确保使用 %w{}

set :stage, :production

server 'company.com', user: 'webmaster', roles: %w{web app db}

部署输出

如果成功，您应该会在输出中看到与此类似的内容:

INFO [2412d16d] Running /home/webmaster/.rbenv/bin/rbenv exec bundle exec rake assets:precompile as webmaster@company.com
DEBUG [2412d16d] Command: cd /var/www/website/releases/20160302030846 && ( export RBENV_ROOT="/home/webmaster/.rbenv" RBENV_VERSION="2.2.3" RAILS_ENV="production" ; /home/webmaster/.rbenv/bin/rbenv exec bundle exec rake assets:precompile )

Answer 1

由于一个非常微妙的拼写错误，您没有正确地为您的服务器分配角色:

server 'company.com', user: 'webmaster', roles: %{web app db}

应该是:

server 'company.com', user: 'webmaster', roles: %w{web app db}

在 Ruby 中，%{} 与双引号字符串相同，而 %w{} 是字符串数组。您需要后者，以便您的服务器具有三个角色，web、app 和 db，而不是一个名为 web 的角色应用数据库。
