Puma - 使用配置文件运行服务器时显示完整日志

I installed puma gem and when I start rails server by rails s I can see full output:

我安装了puma gem,当我通过rails启动rails服务器时,我可以看到完整的输出:

However when I try to run puma by providing config file I can't see full logs anymore:

但是,当我尝试通过提供配置文件来运行puma时,我再也看不到完整的日志了:

Is there any way to show logs as rails s does? I want to have the same behaviour as rails s without running additional command. Is it possible?

有没有办法像rails一样显示日志?我希望在不运行其他命令的情况下拥有与rails s相同的行为。可能吗?

My puma config:

我的美洲狮配置:

workers Integer(ENV['WEB_CONCURRENCY'] || 2)
threads_count = Integer(ENV['MAX_THREADS'] || 1)
threads threads_count, threads_count

preload_app!

rackup      DefaultRackup
port        ENV['PORT']     || 3000
environment ENV['RACK_ENV'] || 'development'

on_worker_boot do
  # Worker specific setup for Rails 4.1+
  # See: https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server#on-worker-boot
  ActiveRecord::Base.establish_connection
end

3 个解决方案

#1

The logs are in log/<rails env>.log. So you could (in a separate tab / window) run:

日志位于log / .log中。所以你可以(在一个单独的选项卡/窗口中)运行:

tail -f log/development.log

And you'll see all your output. If you want the output from rails merged into the puma logs, you could always have rails log to STDOUT:

你会看到你的所有输出。如果你想将rails的输出合并到puma日志中,你可以随时将rails记录到STDOUT:

config.logger = Logger.new(STDOUT)

#2

I've found this command in the Puma github readme:

我在Puma github自述文件中找到了这个命令:

$rails s Puma

Which also results in the desired behavior.

这也导致了期望的行为。

Edit: In fact, as described here after installing Puma, it should automatically be picked up by rails s command without the Puma argument.

编辑:事实上,正如安装Puma后所描述的那样,它应该由rails s命令自动获取而不需要Puma参数。

#3

If it's the logs you're interested in, then you can tail the actual log file. It'd go something like this tail -f log/development.log.

如果它是您感兴趣的日志,那么您可以拖尾实际的日志文件。它就像这个tail -f log / development.log。
