我试图用Capistrano 3创建Unicorn重启任务:

首先,我设置*unicorn_pid*变量:

set :unicorn_pid, "#{shared_path}/tmp/pids/unicorn.pid"

然后我将它传递给重启任务:

  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      execute :kill, "-USR2 `cat #{fetch(:unicorn_pid)}`" if test "[ -f #{fetch(:unicorn_pid)} ]"
      within release_path do
        execute :bundle, "exec unicorn -D -c config/unicorn.rb -E #{fetch(:stage)}"
      end
    end
  end

但是当我跑步时cap production deploy:restart我看到:

DEBUG [f4159760] Running /usr/bin/env [ -f /var/www/shared/tmp/pids/unicorn.pid ] on dev.project.net
DEBUG [f4159760] Command: [ -f /var/www/shared/tmp/pids/unicorn.pid ]

所以,而不是/home/user/project/shared/路径,#{shared_pa​​th}转换为/var/www/shared/

但是当我直接在任务中指定这个路径时,没有unicorn_pid变量,我在输出中看到:

 INFO [567856e3] Running /usr/bin/env kill -USR2 `cat …
