Ruby on Rails生产日志轮换 [英] Ruby on Rails production log rotation

问题描述

在Ruby on Rails生产应用程序上启用日志轮转的最佳方法是什么?

What is the best way to enable log rotation on a Ruby on Rails production app?

是通过在托管服务器上使用logrotate还是在从应用程序初始化记录器时使用一组选项?

Is it by using logrotate on the hosting server or is there a set of options to use when initialising logger from the app?

推荐答案

选项1:syslog + logrotate

您可以配置滑轨，以使用系统日志工具.

Option 1: syslog + logrotate

You can configure rails, to use the systems log tools.

config/environments/production.rb 中的示例.

# Use a different logger for distributed setups
config.logger = SyslogLogger.new

这样，您登录到syslog，并可以使用默认的logrotate工具旋转日志.

That way, you log to syslog, and can use default logrotate tools to rotate the logs.

另一种选择是简单地配置logrotate以拾取rails留下的日志. 例如，在Ubuntu和Debian上，该文件位于名为/etc/logrotate.d/rails_example_com的文件中.

Another option is to simply configure logrotate to pick up the logs left by rails. On Ubuntu and Debian that would be, for example, in a file called /etc/logrotate.d/rails_example_com.

/path/to/rails.example.com/tmp/log/*.log {
    weekly
    missingok
    rotate 52
    compress
    delaycompress
    notifempty
    copytruncate
}

按照下面的建议，建议在Rails中使用copytruncate，以避免必须重新启动Rails应用程序.

As per suggestions below, in Rails it is advised to use copytruncate, to avoid having to restart the Rails app.

删除了共享脚本/结尾脚本"，因为此处未使用它们，并且根据注释会导致问题.并按照注释建议删除了create 640 root adm.

removed "sharedscripts/endscript" since they are not used here and cause problems according to comment. And removed create 640 root adm as per comment suggested.
