服务器作为守护程序运行时的根路径问题 [英] root path issues when server is run as a daemon
问题描述
我有几个访问文件系统的视图以及一些gems。在我将服务器作为守护程序运行之前,这似乎工作正常。 rails(4.2.3)
i have several views, as well as some gems, that access the filesystem. this seems to work fine until i run the server as a daemon. rails (4.2.3)
例如,在我的一个视图中,我访问应用程序根目录中的README文件
for example in one of my views I access the README file in the root of the app
File.read('README.md')
作为守护程序运行时,出现错误没有这样的文件或目录@ rb_sysopen-README.md
when running as a daemon, i get the error No such file or directory @ rb_sysopen - README.md
错误页面显示Rails.root路径,这是正确的。我可以通过以下方法解决此问题:
the error page shows the Rails.root path, which is correct. i CAN fix this problem by doing:
File.read("#{Rails.root}/README.md")
但是,这个问题不仅破坏了我的观点。似乎与Rails服务器有关。
however this issue breaks more than just my views. It would seem an issue with the rails server.
推荐答案
这是守护进程的工作方式- chdir
到/或另一个工作目录。一些程序允许您指定守护进程的工作目录。例如, puma
服务器默认使用当前目录,因此它可能对您有用。
This is how daemonized process works - chdir
to / or another working directory. Some programs allow you to specify working directory for daemon process. For example puma
server uses current directory by default so it might work for you.
