Rails 应用程序的 Digital Ocean 中的 cap deploy:cold 错误

Question

我真的很想部署一个应用程序，并且一直在关注 railstutorial Michael Hartl。现在，我即将在 Digital Ocean 中部署我的第一个应用程序，但我一直运行遇到很多问题。不管怎样，除了这个大的，大部分都已经完成了。

我遵循了 Hoang Pham 的 blog 和 [Andrew Gertig][3] 的教程。

无论如何，这是我第一次来这里。让我在 advance.Everytime 中表达我的感谢，我在 $ cap deploy:cold，在我的本地机器上我总是得到这个错误。

failed: "rvm_path=$HOME/.rvm $HOME/.rvm/bin/rvm-shell 'default' -c 'cd /home/deployer/apps/tiangge/releases/20150123165947 && bundle install --gemfile /home/deployer/apps/tiangge/releases/20150123165947/Gemfile --path /home/deployer/apps/tiangge/shared/bundle --deployment --quiet --without development test'" on 128.199.74.8

而且我也注意到了这一点，这就是为什么我在 VPS

中再次做了 gem uninstall bundler 和 gem install bundler

我完成的步骤：

Answer 1

您遇到了 Cannot allocate memory 错误。这意味着您的部署机器上没有足够的 RAM 用于捆绑程序。

您可以添加交换分区来执行此操作，或者创建具有更大 RAM 的 DO 液滴 space。

关于向 DO 液滴添加交换的好教程https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-12-04

Answer 2

我在尝试在 Digital Ocean 上部署 Dokku 时遇到了类似的问题/Ubuntu。在根数字海洋用户的 SSH 会话中使用 3 行代码运行轻松修复：

dd if=/dev/zero of=/swapfile bs=1024 count=1024000
mkswap /swapfile
swapon /swapfile
