Rails日志在生产中无法正常工作

Question

日志有问题.它们在开发上运行良好,但在生产中我无法编写自己的消息.

除了安装Devise和Mongoid之外,我没有更改配置文件中的任何内容.但为了以防万一,我尝试取消注释#config.log_level =:debug in production.rb

控制器:

class PagesController < ApplicationController
  def home
    logger.fatal 'bla'
  end

  def about
  end
end

终端(日志权限):

root@ubuntu:/srv/www/myapp# ls log -lah
total 496K
drwxr-xr-x  2 myapp root    4.0K 2012-02-21 17:18 .
drwxr-xr-x 14 root  root    4.0K 2012-02-20 14:54 ..
-rw-r--r--  1 myapp myapp    35K 2012-02-21 16:23 development.log

-rw-r--r--  1 myapp myapp      0 2012-02-21 17:18 production.log

航站楼(乘客):

root@ubuntu:/srv/www/myapp# passenger start -e production -p 80 --user=myapp

假设您使用的是Rails 3.2.0或Rails 3.2.1,这是一个已知问题(请参阅https://github.com/rails/rails/issues/4277).它已经修复,但还没有发布.

解决方法是添加初始化程序:

Rails.logger.instance_variable_get(:@logger).instance_variable_get(:@log_dest).sync = true if Rails.logger

更新:Rails 3.2.2解决了这个问题.
