At step 8 I'm asked to restart Rails server but how?
在第 8 步，我被要求重新启动 Rails 服务器，但如何重新启动？
I'm assuming via a command line, but from within the already open ruby terminal window or a new one?
我假设是通过命令行，但是在已经打开的 ruby 终端窗口中还是在一个新的终端窗口中？

On OSX, you can take advantage of the UNIX-like command line - here's what I keep handy in my .bashrc to enable me to more easily restart a server that's running in background (-d) mode (note that you have to be in the Rails root directory when running this):
在 OSX 上，您可以利用类似 UNIX 的命令行 - 这是我在 .bashrc 中随身携带的内容，使我能够更轻松地重新启动在后台 (-d) 模式下运行的服务器（请注意，您必须处于运行时的 Rails 根目录）：
alias restart_rails='kill -9 `cat tmp/pids/server.pid`; rails server -d'
My initial response to the comment by @zane about how the PID file isn't removed was that it might be behavior dependent on the Rails version or OS type. However, it's also possible that the shell runs the second command (rails server -d) sooner than the killcan actually cause the previous running instance to stop.
我对@zane 关于如何不删除 PID 文件的评论的最初回应是，它的行为可能取决于 Rails 版本或操作系统类型。但是，也有可能 shell 运行第二个命令 ( rails server -d) 的时间比kill实际导致前一个正在运行的实例停止的时间早。
So alternatively, kill -9 cat tmp/pids/server.pid && rails server -dmight be more robust; or you can specifically run the kill, wait for the tmp/pidsfolder to empty out, then restart your new server.
因此，或者，kill -9 cat tmp/pids/server.pid && rails server -d可能更健壮；或者您可以专门运行kill，等待tmp/pids文件夹清空，然后重新启动新服务器。

In case that doesn't work there is another way that works especially well in Windows: Kill localhost:3000 process from Windows command line
如果这不起作用，还有另一种在 Windows 中特别有效的方法：Kill localhost:3000 process from Windows command line

if you are not able to find the rails process to kill it might actually be not running. Delete the tmp folder and its sub-folders from where you are running the rails server and try again.
如果您无法找到要杀死的 rails 进程，它实际上可能没有运行。从运行 rails 服务器的位置删除 tmp 文件夹及其子文件夹，然后重试。
