===== updateIt is very strange that all browses in my machine can visit the site while it's not available on other machine! I only visit the page with Chrome before I stop the application. It seems to be a cache problem, but how cache shared among browsers..
====== update很奇怪，我的机器上所有的浏览都可以访问该站点，而在其他机器上不可用！我只在停止应用程序之前使用 Chrome 访问该页面。这似乎是一个缓存问题，但是浏览器之间如何共享缓存..

You can kill all node processes using pkill node
您可以使用以下命令杀死所有节点进程 pkill node
or you can do a ps Tto see all processes on this terminal
then you can kill a specific process ID doing a kill [processID]example: kill 24491
或者您可以执行 aps T以查看此终端上的所有进程，
然后您可以杀死特定的进程 ID，kill [processID]例如：kill 24491
Additionally, you can do a ps -helpto see all the available options
此外，您可以执行 aps -help查看所有可用选项

If all those kill process commands don't work for you, my suggestion is to check if you were using any other packages to run your node process.
如果所有这些 kill process 命令都对您不起作用，我的建议是检查您是否使用任何其他包来运行您的节点进程。
I had the similar issue, and it was due to I was running my node process using PM2(a NPM package). The kill [processID]command disables the process but keeps the port occupied. Hence I had to go into PM2 and dump all node process to free up the port again.
我遇到了类似的问题，这是因为我使用 PM2（一个 NPM 包）运行我的节点进程。该kill [processID]命令禁用进程但保持端口被占用。因此我不得不进入 PM2 并转储所有节点进程以再次释放端口。

If you want know, the how may nodejs processes running then you can use this command
如果您想知道 nodejs 进程如何运行，那么您可以使用此命令
ps -aef | grep node
So it will give list of nodejs process with it's project name. It will be helpful when you are running multipe nodejs application & you want kill specific process for the specific project.
所以它会给出带有项目名称的nodejs进程列表。当您运行 multipe nodejs 应用程序并且想要终止特定项目的特定进程时，这将很有帮助。
Above command will give output like
上面的命令将给出类似的输出
XXX 12886 1741 1 12:36 ? 00:00:05 /home/username/.nvm/versions/node/v9.2.0/bin/node --inspect-brk=43443 /node application running path.
So to kill you can use following command
所以要杀死你可以使用以下命令
kill -9 12886
So it will kill the spcefic node process
所以它会杀死 spcefic 节点进程
