Ruby on rails Unicorn仍指向旧版本文件夹

部署顺利,服务器上的当前文件夹按预期包含更新的文件
但是,发生了一些我不理解的非常奇怪的事情:
在我的流程开始时,我有一句话:
logger = Logger.new "#{Rails.root}/log/web_agents.log"
但仍会出现此错误:
No such file or directory - /home/deployer/apps/myapp/releases/20120612122610/log/web_agents.log
为什么是20120612122610???这是一个我甚至删除的旧版本
为什么Unicorn不指向上一个版本
为了进行测试,我甚至将Rails.root替换为当前路径的硬编码路径
还是有同样的错误。。。我杀了独角兽,停止,强迫停止…没关系
有什么想法吗
我确信进程是使用“当前”文件夹中上次更新的文件启动的,因为当我删除一个文件时,进程无法工作,并且出现许多错误
已更新

我发现问题出在哪里 事实上,Unicorn和Sidekiq之间存在故障排除 事实上,正如我在上面的一条评论中所说,这个过程是由Sidekiq发起的 首先,在deploy.rb中,必须有以下行:
require 'sidekiq/capistrano'
这允许部署过程优雅地重新启动Sidekiq。
见:
其次,在unicorn.rb中,必须有这样的块:
after_fork do |server, worker|
Sidekiq.configure_client do |config|
config.redis = { :size => 1 }
end
end
有关它的更多信息,请参见:
现在,没有更奇怪的问题:)
一个可能的解释是:
可能Sidekiq管理一些缓存,防止它基于上一版本…这就是为什么重新启动加上干净地启动Unicorn和Sidekiq就足够了。请发布您的
config/Unicorn.rb
@iblue我想知道,进程在后台使用redis服务器。也许这一个有一种缓存。。。我要重新开始……你说的“我在我的流程开始时就有这一行”到底是什么意思。您将包含Logger.new的语句放在哪里了?哪个文件?什么时候启动?@iblue实际上这个过程代表一个作业任务。此作业任务通过以下行推送到Sidekiq(线程工作者管理器):job.find(id).run。“run”方法在一开始就包含一行:logger.info“start processing”。这个“logger”实际上是一个方法(是的,也是一个名为“logger”的方法),这个方法的第一行是:logger=logger.new“#{Rails.root}/log/web_agents.log”@iblue我刚刚重新启动了Redis服务器,仍然有相同的错误。。。
