Rails:无法访问日志文件

Question

重新启动我的rails应用程序时出现以下错误.我以前遇到过这个问题,在另一个服务器上有另一个应用程序,但不记得是什么问题,或者我是如何解决它的.

Rails Error: Unable to access log file. Please ensure that /apps/staging/releases/20090310162127/log/staging.log exists and is chmod 0666. The log level has been raised to WARN and the output directed to STDERR until the problem is fixed.

我正在Ubuntu上部署到带有capistrano的杂种群集.

当我做 ls -l /apps/staging/releases/20090310162127/log/staging.log

结果是:

-rw-rw-rw- 1 me grp 51 Mar 10 16:07 /apps/staging/releases/20090310162127/log/staging.log

日志目录是link/ apps/staging/shared/log.

这是怎么回事？

Answer 1

事实证明这是一个微妙的铁轨错误:

当在这两行中引发异常时

logger = ActiveSupport::BufferedLogger.new(configuration.log_path)
logger.level = ActiveSupport::BufferedLogger.const_get(configuration.log_level.to_s.upcase)

rails假定它找不到日志文件.但是,实际错误发生在第二行:NameError,因为常量不正确.原因是我的配置文件中存在遗留日志级别:

config.log_level = Logger::INFO

Rails 2.2使用自己的记录器,并不理解上面的行.

解决方案:删除行,或使用:

config.log_level = :info
