使用capistrano在生产中运行rpush作为守护进程

Question

我已经设置了我的rails应用程序与rpush一起使用.它在开发中使用时在本地工作正常rpush start.但是现在我想使用capistrano- 2.15.5将它部署到我的EC2服务器上.

我的一部分deploy.rb:

after "deploy:stop",    "delayed_job:stop"
after "deploy:stop",    "rpush:stop"

after "deploy:start",   "delayed_job:start"
after "deploy:start",   "rpush:start"

after "deploy:restart", "delayed_job:restart"
after "deploy:restart", "rpush:restart"

namespace :rpush do
  %w[start stop restart].each do |command|
    desc "#{command} rpush deamon"
    task command, roles: :app, except: {no_release: true} do
      run "cd #{deploy_to}/current && bundle exec rpush #{command}"
    end
  end
end

现在,问题

• 它始于开发环境.我试着理解这个页面告诉我该怎么做,但我做不到.
• 我不知道pid是存储在/currentdir还是/shareddir中.它应该在共享中,以便文件在部署之间保持不变

如果有人这样做(即使以不同的方式),请告诉我如何.

或者,我怎样才能修复我的帽子食谱 /initializers/rpush

Answer 1

对于Capistrano 3:

after :finished, :restart_rpush do
  on roles(:web) do
    within release_path do
      with rails_env: fetch(:rails_env) do
        execute :bundle, :exec, "rpush stop -e #{fetch(:rails_env)}"
        execute :bundle, :exec, "rpush start -e #{fetch(:rails_env)}"
      end
    end
  end
end

然后检查tmp是否正确链接了其他目录:

set :linked_dirs, %w{log tmp/pids tmp/cache tmp/sockets vendor/bundle public/uploads}
