capistrano部署后ec2服务器中缺少puma.sock [英] puma.sock missing in ec2 server after capistrano deployment

问题描述

在通过Capistrano将生产中的红宝石部署到ec2上的实例上后，我在Nginx错误日志中收到以下错误.亚马逊公共主机显示502 Bad Gateway nginx/1.10.0(Ubuntu). 我从 https://www.sitepoint.com/部署您的Rails应用到aws/ 似乎在运行cap生产部署时未创建puma.sock.

I am getting the following error in the nginx error logs after deploying production a ruby on rails project through capistrano to an instance on ec2. The amazon public host shows a 502 Bad Gateway nginx/1.10.0 (Ubuntu). I followed the tutorial from https://www.sitepoint.com/deploy-your-rails-app-to-aws/ It seems the puma.sock is not being created when I run cap production deploy..

2017/06/28 01:09:57 [crit] 12802#12802: *1 connect() to unix:/home/deploy/app_name/shared/tmp/sockets/puma.sock failed (2: No such file or directory) while connecting to upstream, client: 173.198.30.2, server: localhost, request: "GET / HTTP/1.1", upstream: "http://unix:/home/deploy/app_name/shared/tmp/sockets/puma.sock:/", host: "host"

以下是我的deploy.rb

The following is in my deploy.rb

set :application, 'app_name'
set :repo_url, '[e-mail]:github_account/app_name.git' # Edit this to match your repository
set :branch, :master
set :deploy_to, '/home/deploy/app_name'
set :pty, true
set :linked_files, %w{config/database.yml config/application.yml}
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system public/uploads}
set :keep_releases, 5
set :rvm_type, :user
set :rvm_ruby_version, 'ruby-2.3.3' # Edit this if you are using MRI Ruby

set :puma_rackup, -> { File.join(current_path, 'config.ru') }
set :puma_state, "#{shared_path}/tmp/pids/puma.state"
set :puma_pid, "#{shared_path}/tmp/pids/puma.pid"
set :puma_bind, "unix://#{shared_path}/tmp/sockets/puma.sock"    #accept array for multi-bind
set :puma_conf, "#{shared_path}/puma.rb"
set :puma_access_log, "#{shared_path}/log/puma_error.log"
set :puma_error_log, "#{shared_path}/log/puma_access.log"
set :puma_role, :app
set :puma_env, fetch(:rack_env, fetch(:rails_env, 'production'))
set :puma_threads, [0, 8]
set :puma_workers, 0
set :puma_worker_timeout, nil
set :puma_init_active_record, true
set :puma_preload_app, false

请帮助！ 预先感谢！

推荐答案

在使用Capistrano和nginx安装Rails的EC2实例上工作时，我遇到了同样的错误

I was getting this same error when working on EC2 instance installing Rails with Capistrano and nginx

如果遇到502错误，则在需要'capistrano/puma'之后将install_plugin Capistrano::Puma添加到Capfile中.

if you are getting 502 error Add install_plugin Capistrano::Puma into your Capfile after require 'capistrano/puma'.
