无法在 capistrano 3 中启动 Unicorn 服务器

Question

这是我的配置/unicorn/development.rb

app_path = "/home/ec2-user/apps/app_dev/current"

worker_processes 1
preload_app false
timeout 300
listen 3333

working_directory app_path
pid "#{app_path}/tmp/pids/unicorn.pid"

rails_env = 'development'

stderr_path "log/unicorn.log"
stdout_path "log/unicorn.log"

这是我的 Capfile

# Load DSL and Setup Up Stages
require 'capistrano/setup'

# Includes default deployment tasks
require 'capistrano/deploy'


require 'capistrano/rvm'
# require 'capistrano/rbenv'
# require 'capistrano/chruby'
require 'capistrano/bundler'
# require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'
require 'capistrano3/unicorn'
# require 'sidekiq/capistrano'

# Loads custom tasks from `lib/capistrano/tasks' if you have any defined.
Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r }

在我的本地环境中运行以下命令 "cap development unicorn:start" 时

我收到以下错误

让我知道如何在 master 分支中启动独角兽服务器

Answer 1

从以下行：

没有这样的文件或目录 - /home/ec2-user/apps/app_dev/current/config/unicorn/.rb

我推测独角兽正在寻找/home/ec2-user/apps/app_dev/current/config/unicorn/<something should be here>.rb。这个“东西应该在这里”，我希望是“发展”，我猜它正试图从fetch(:stage)那里获得。

尝试添加到development.rb

set :stage, :development

编辑

我没有注意到我所建议的逻辑的循环性（在文件中添加一些未找到的内容以显示它的位置...） - 您应该将此行添加到 config/deploy/development.rb，而不是 @987654328 @... :-P

更新

既然这样不行，我在capistrano3/unicorncode挖了一下，发现它要找的环境变量是:rails_env，所以也加上

set :rails_env, :development
