我正在尝试在我的VPS上部署一个简单的rails应用程序，但是当capistrano尝试启动puma时，我总是收到此错误消息：

The signal USR1 is in use by the JVM and will not work correctly on this platform
[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.

我的VPS运行Centos 6和jRuby 1.7.11。 我还尝试运行bundle install --binstubs然后

RAILS_ENV=production bin/puma -p 9292 -e production -C config/puma.rb

但仍然会发生同样的错误。

知道为什么会这样吗？

1 个答案:

答案 0 :(得分：2)

“USR1”文本不是错误，在JRuby下运行时只是一个警告。

真正的错误是这个：

NativeLibrary.java:87:in `loadNativeLibraries':
  java.lang.UnsatisfiedLinkError: /lib/libc.so.6: wrong ELF class: ELFCLASS32

这是因为您正在运行64位JRE，但尝试加载32位libc。
