How to kill an open process on node.js?
提问by MaiaVictor
I'm trying to set up a build-system for Node.js on sublime, so I can press F7 to call "node" on the openned file. The problem is that the process is then open forever, so, the second time I use F7 I get an add-in-use.
我正在尝试在 sublime 上为 Node.js 设置一个构建系统，因此我可以按 F7 在打开的文件上调用“node”。问题是该过程将永远打开，因此，第二次使用 F7 时，我得到了一个加载项。
Is there a way I can kill the openned "node.exe" process from node.js?
有没有办法可以从 node.js 中杀死打开的“node.exe”进程？

Use the following set of commands to identify the process running on a given port and to termiate it from the command line
使用以下命令集识别在给定端口上运行的进程并从命令行终止它
sudo fuser -v 5000/tcp // gives you the process running on port 5000
It will output details similar to the one shown below
它将输出类似于下面显示的详细信息
USER PID ACCESS COMMAND
5000/tcp: almypal 20834 F.... node
Then use
然后使用
sudo fuser -vk 5000/tcp
to terminate the process. Check once again using
来终止进程。再次检查使用
sudo fuser -v 5000/tcp
to ensure that the process has terminated.
以确保该过程已终止。
On Windows you could use the following steps
在 Windows 上，您可以使用以下步骤
C:\> tasklist // will show the list of running process'
Image Name PID Session Name Session# Mem Usage
System 4 console 0 236 K
...
node.exe 3592 console 0 8440 k
Note the PID corresponding to your node process, in this case 3592. Next run taskkill to terminate the process.
请注意与您的节点进程对应的 PID，在本例中为 3592。接下来运行 taskkill 以终止该进程。
C:\> taskkill /F /PID 3592
Or /IM switch
或 /IM 开关
C:\> taskkill /F /IM node.exe

From within Node.js:
在 Node.js 中：
var die = function(quitMsg)
{
console.error(quitMsg)
process.exit(1);
}
die('Process quit');
There are certain methods availablefor exiting that are only available for POSIX (i.e. not Windows) that will exit a process by its process id.
有某些可用于退出的方法仅适用于 POSIX（即不是 Windows），它们将通过进程 ID 退出进程。
Also, note that you might be able to send a kill() signal using this method, which does not say it isn't available for Windows:
另请注意，您可以使用此方法发送 kill() 信号，但这并不表示它不适用于 Windows：
process.kill(pid, [signal])

if you want to kill all process than
如果你想杀死所有进程而不是
sudo killall -9 node
if you want to kill process on selected port than
如果你想杀死选定端口上的进程而不是
sudo kill `sudo lsof -t -i:3100
here 3100 is port
这里 3100 是端口

If sublime you say is sublimeText plugin, I have the same issue, and send TCP server a message 'shutdown' from python code, then
如果你说的 sublime 是 sublimeText 插件，我有同样的问题，并从 python 代码向 TCP 服务器发送消息“关闭”，然后
app.js
应用程序.js
TCPserver
.on('connection', function(socket)
{
socket.pipe(require('through')
(function(data)
{ //----------------------------
if (data.toString() === 'shutdown')
{
process.exit();
}
//--------------------------
}));
socket.end();
})

Similarly to what @Alex W said, you can send a kill signal to the process so long as you have its process ID, or PID using the following node function:
与@Alex W 所说的类似，只要您拥有进程 ID 或使用以下节点函数的 PID，您就可以向该进程发送终止信号：
process.kill(pid, [signal])
process.kill(pid, [signal])
In my case, I had the PIDs readily available as I was spawning child_process().spawn.pid. I have tested it and it does work on Win 7 x64.
就我而言，我在生成child_process().spawn.pid. 我已经对其进行了测试，它确实可以在 Win 7 x64 上运行。
