ruby-on-rails - Capistrano: Killed RAILS_ENV=production RAILS_GROUPS=assets bundle exec rake assets:precompile

Question

我昨天整个下午都在处理这个问题，例如我找到了this主题，这不适合我。

然后我在这里找到了一个关于 SO 的主题，其中给出了将 load 'deploy/assets' 添加到 Capfile 的建议。终于成功了!

但是今天早上当我尝试部署另一个代码时，我又遇到了这个错误:

 ** [out :: IP] bash: line 1: 15213 Killed                  RAILS_ENV=staging RAILS_GROUPS=assets bundle exec rake assets:precompile
    command finished in 38500ms
*** [deploy:update_code] rolling back

我快疯了，昨天一切都很好，但今天 - 突然 - 又是同样的错误。这是我的设置:

标题:

load 'deploy'
load 'config/deploy' # remove this line to skip loading any of the default tasks
load 'deploy/assets'

部署/生产.rb:

...
namespace :deploy do

  task :setup_config, roles: [:app] do
    sudo "ln -nfs #{current_path}/config/nginx.conf /etc/nginx/sites-enabled/app"
    sudo "ln -nfs #{current_path}/config/unicorn_init_production.sh /etc/init.d/unicorn_app-production"
    run "mkdir -p #{shared_path}/config"
    put File.read("config/database.yml"), "#{shared_path}/config/database.yml"
    puts "Now edit the config files in #{shared_path}."
  end
  after "deploy:setup", "deploy:setup_config"

  task :symlink_config, roles: [:app] do
    run "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml"
  end
  after "deploy:finalize_update", "deploy:symlink_config"
  after "deploy:create_symlink", "deploy:restart"

  desc "Make sure local git is in sync with remote."
  task :check_revision, roles: [:web] do
    unless `git rev-parse HEAD` == `git rev-parse origin/master`
      puts "WARNING: HEAD is not the same as origin/master"
      puts "Run `git push` to sync changes."
      exit
    end
  end
  %w[stop].each do |command|
    desc "#{command} unicorn server"
    task command, roles: :app, except: {no_release: true} do
      run "/etc/init.d/unicorn_app-production #{command}"
    end
  end


  %w[restart].each do |command|
    desc "#{command} unicorn server"
    task command, roles: :app, except: {no_release: true} do
      run "/etc/init.d/unicorn_app-production #{command}"
    end
  end

  before "deploy", "deploy:check_revision"  
end

部署.rb:

require "capistrano/ext/multistage"
require "rvm/capistrano"
require 'bundler/capistrano'
require 'delayed/recipes' # added for running deplayed jobs

set :application, 'app'
set :bundle_flags, "--quiet --no-cache"

set :scm, :git
default_run_options[:pty] = true
set :deploy_via, :remote_cache
set :repository, 'git@bitbucket.org:name/repo.git'
set :branch, "master"
set :pty, true
set :keep_releases, 5

我会非常乐于提供每条建议!

谢谢大家

服务器终止进程，查看服务器上的dmesg，我认为你没有编译内存。dmesg 返回:

[5689488.101760] Out of memory: Kill process 31427 (ruby) score 184 or sacrifice child [5689488.102528] Killed process 31427 (ruby) total-vm:948244kB, anon-rss:235856kB, file-rss:0kB

您可以在本地编译 Assets 并移动到服务器，而无需升级内存。

看这个gist或者这个 gem .
