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

...有没有办法像rails s那样显示日志？我想有相同的行为作为rails s没有运行额外的命令。有可能吗？
我的puma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

日志在
log/<rails env>.log中。因此，您可以（在单独的选项卡/窗口中）运行：你会看到所有的输出。如果你想将rails的输出合并到puma日志中，你可以让rails的日志记录到
STDOUT：eimct9ow2#
我在Puma github readme中找到了这个命令：
这也会导致所需的行为。
编辑：实际上，as described here在安装Puma之后，它应该会自动被rails的命令选中，而不需要Puma参数。

如果您感兴趣的是日志，那么可以跟踪实际的日志文件。它会像这样的
tail -f log/development.log。nuypyhwy4#
如果您使用foreman或
Procfile，则可以将tail -f log添加到Procfile。这是我用途：然后我开始像这样的rails：
实际上，我在
.zshrc中有一个别名：所以我可以简单地启动Rails：

在我的情况下，我试过了
但我得到了一堆日志错误说：错误代码：#Logger的未定义方法'silence'：...
我找到的解决方案是添加到config/environments/development.rb

这可能是由于您的Puma配置文件中的以下行：
尝试删除此行或将worker设置为0。
这样，Puma将在单一模式下运行，并开始打印所有日志。
