Question

我已使用capistrano AWS部署了我的应用，nginx和unicorn。当我打开我的主页时，它是空的。这是我的unicorn日志

Started GET "/" for 111.111.111.111 at 2014-03-10 12:50:02 +0000

我的最新版本是20140310124541，但缺少的模板错误来自之前的版本20140310084512。可能是什么问题。 current文件夹符号链接已正确创建。

Answer 1

您需要确保重新启动nginx / unicorn。一旦程序在符号链接中查找文件夹/文件，它将指向目标。因此，当capistrano指向当前最新版本时，nginx仍在查看现在很可能被删除的旧目标。

确保您已重启设置，如下所示：https://github.com/sosedoff/capistrano-unicorn

Answer 2

--trace旗帜给了我更多信息。在我的情况下，宝石丢失了，我没有发现错误。 passenger是宝石。

Answer 3

akshah123的解决方案是答案，我想分享我的看法，如果这可能对其他人有所帮助。

在deploy / your_environment.rb（例如：deploy/staging.rb）或deploy.rb中，您可以添加：

after 'deploy:publishing', 'deploy:restart'
namespace :deploy do
  desc 'for resetting symlinks that are getting stuck in the normal deploy process'
  task :restart do
    invoke 'unicorn:reload'
  end
end

根据Capistrano的设置方式，您可能会看到以下内容：

Skipping task `unicorn:start'.
Capistrano tasks may only be invoked once. Since task `unicorn:start' was previously invoked, invoke("unicorn:start") at /Users/newman/.rvm/gems/ruby-2.6.3/gems/capistrano3-unicorn-0.2.1/lib/capistrano3/tasks/unicorn.rake:49 will be skipped.
If you really meant to run this task again, use invoke!("unicorn:start")
THIS BEHAVIOR MAY CHANGE IN A FUTURE VERSION OF CAPISTRANO. Please join the conversation here if this affects you.

在大多数情况下，这应该可以解决，因为正在处理冗余，并且出现了重新映射符号链接的预期结果。在这种情况下，可能不需要/不需要从消息中建议的修复，因为我们从调用unicorn:start隐式调用unicorn:reload，换句话说：invoke! unicorn:reload无法处理/阻止呈现此消息。

Capistrano从旧版本中发出错误。 ::的ActionView MissingTemplate
