如何将 Node.js 作为后台进程运行并且永不消亡? [英] How to run Node.js as a background process and never die?

问题描述

我通过 putty SSH 连接到 linux 服务器.我尝试将它作为这样的后台进程运行:

I connect to the linux server via putty SSH. I tried to run it as a background process like this:

$ node server.js &

但是，2.5 小时后终端变为非活动状态并且进程终止.无论如何，即使终端断开连接，我也可以保持进程存活吗?

However, after 2.5 hrs the terminal becomes inactive and the process dies. Is there anyway I can keep the process alive even with the terminal disconnected?

实际上，我尝试了 nohup，但是只要我关闭 Putty SSH 终端或拔下互联网，服务器进程就会立即停止.

Actually, I tried nohup, but as soon as I close the Putty SSH terminal or unplug my internet, the server process stops right away.

我需要在 Putty 中做些什么吗?

Is there anything I have to do in Putty?

有一个 node.js 模块，forever.它将 node.js 服务器作为守护程序服务运行.

There is a node.js module, forever. It will run node.js server as daemon service.

推荐答案

简单的解决方案(如果你对返回进程不感兴趣，只希望它继续运行):

Simple solution (if you are not interested in coming back to the process, just want it to keep running):

nohup node server.js &

还有 jobs 命令可以查看这些后台进程的索引列表.您可以通过运行 kill %1 或 kill %2 来终止后台进程，数字是进程的索引.

There's also the jobs command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1 or kill %2 with the number being the index of the process.

强大的解决方案(允许您重新连接到交互过程):

Powerful solution (allows you to reconnect to the process if it is interactive):

screen

然后您可以按 Ctrl+a+d 分离，然后通过运行 screen -r

You can then detach by pressing Ctrl+a+d and then attach back by running screen -r

还要考虑屏幕的更新替代品 tmux.

Also consider the newer alternative to screen, tmux.
