在尝试部署,其他问题都解决了,剩下这 4 块不知道是哪里出错了导致的。

执行的 cap production deploy --trace,以下是失败的几处地方 (完整的部署 trace 信息在最后)。希望能得到帮助...

  1. release 下的 database.yml
  2. release 下的 assets
  3. 执行 bundle check,提示 missing gems
  4. shared 下的 puma.pid

我的 gemfile 如下:

source "http://gems.ruby-china.org"

gem 'rails', '~> 5.1.4'
gem 'sqlite3'
gem 'puma', '~> 3.7'
gem 'sprockets'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.2'
gem 'turbolinks', '~> 5'
gem 'jbuilder', '~> 2.5'
gem 'mysql2'
# Redis
gem 'redis'
gem 'hiredis'
gem 'redis-namespace'
gem 'redis-objects'

group :development do
  gem 'capistrano', '~> 3.4.0', require: false
  gem 'capistrano-bundler', require: false
  gem 'capistrano-rails', require: false
  gem 'capistrano-rvm', require: false
  gem 'capistrano3-puma', require: false
  gem 'pry-nav'
  # Better Errors
  gem 'better_errors'
  gem 'binding_of_caller'
  gem 'spring'
  gem 'spring-commands-rspec'
  gem 'listen'
end

这是 capfile.rb

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

require 'capistrano/rails'
require 'capistrano/bundler'
require 'capistrano/rvm'
require 'capistrano/puma'

set :puma_init_active_record, false  # Change to true if using ActiveRecord

set :linked_files, fetch(:linked_files, []).push('config/database.yml')
set :shared_files, fetch(:shared_files, []).push('tmp')

namespace :puma do
  desc 'Create Directories'
  task :make_dirs do
    on roles(:app) do
      execute "mkdir #{shared_path}/tmp/sockets -p"
      execute "mkdir #{shared_path}/tmp/pids -p"
    end
  end

  before :start, :make_dirs
end

task :compile_assets do
  on roles(:app) do
    execute "cd #{current_path}"
    execute "RAILS_ENV=production bundle exec rails assets:precompile"
  end
end

namespace :deploy do
  desc 'Initial Deploy'
  task :initial do
    on roles(:app) do
      before 'deploy:restart', 'puma:start'
      invoke 'deploy'
    end
  end

  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      invoke 'puma:restart'
    end
  end

  after  :finishing,    :compile_assets
  after  :finishing,    :cleanup
  after  :finishing,    :restart
end

这是报错的地方

猜测,是 rvm 问题,是不是没有建 rvm 的 gemset?

cap 是根据命令的返回值,来反馈给你信息的,返回 0 就认为是正确。其实并不是真正错了,可能只是类似软连建立过了,返回了 1,才提示给你。

set :format,        :pretty
set :log_level,     :info

试试在 deploy 里加上这两句。

那上面这几个报错应该不影响部署的。

恩,看来应该是这样。但那几个报错真是视觉污染...
