Nginx Capistrano没有真正重新启动服务器？

我使用Capistrano 2.15和Nginx在DigitalOcean水滴上运行

有时，特别是当我安装新的gems或运行迁移时，我需要硬重置我的drop以使更改生效

如果我在运行时只是在某个地方更改代码，则这不适用

cap deploy:restart 

很好

另外，当我登录到我的机器并运行

service nginx restart 

它无助于捕获新的迁移

你用独角兽还是乘客

请将代码粘贴到deploy.rb unicorn.rb（如果您使用unicorn）和unicorn_init.sh（或您创建符号链接的sh文件）中

最后一个问题是您在fork之后使用的fork之前的问题？（零停机部署？
您的问题是什么？您定义了哪些其他任务（即部署时：重新启动）？在没有任何代码/配置的情况下，我们如何复制它？嗨，matanco。是的，我使用cap:deploywithunicorn和nginx。我粘贴了deploy.rb，没有使用before_fork/after_fork，我使用了两个额外的任务：tail_日志、用于资产和上传的符号链接以及database.yml
