Capistrano上的Deploy：symlink指向“当前”目录。先前版本的目录 [英] Deploy:symlink on capistrano points the "current" directory to previous release

问题描述

我正在使用capistrano部署我的Ruby on Rails项目。我使用的是Dreamhost VPS，自几周前以来，在Capistrano或乘客上没有任何变化，我开始在部署过程中遇到了一个奇怪的问题：

I am using capistrano to deploy my Ruby on Rails project. I am on a Dreamhost VPS and since a few weeks ago, with no change in capistrano or passenger, I began to experience a strange problem with the deployment:

每次capistrano在部署我的应用程序时，一切正常，除了deploy：symlink（默认情况下被调用）之外，应该将当前目录指向最新版本。尽管新版本已正确部署到版本目录中，但问题是当前符号链接始终设置为先前版本，而不是新版本。因此，我可以部署应用程序，但我总是必须连续运行两次部署。

Every time capistrano is deploying my application, everything goes right except deploy:symlink (which is called by default) that should point the "current" directory to the newest release. Although the new release is deployed properly to the "releases" directory, the problem is the "current" symlink is always set to previous release instead of the new one. So I can deploy apps but I always have to run the deploy two times in a row.

其他人以前曾经经历过这个问题或可以帮助我解决吗？

Has anybody else experienced this before or can help me solve it?

谢谢！

推荐答案

我通过其他部署任务解决了此问题，该任务使用不同的内部变量名称以及最新发行版的正确路径（release_path而不是latest_path或类似的名称）来重新创建符号链接

I solved this with an additional deploy task that recreates the symlink using a different internal variable name with the correct path to the latest release (release_path instead of latest_path or something like that).

namespace :deploy do
  desc "Recreate symlink"
  task :resymlink, :roles => :app do
    run "rm -f #{current_path} && ln -s #{release_path} #{current_path}"
  end
end

after "deploy:create_symlink", "deploy:resymlink", "deploy:update_crontab"
