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

我通过腻子SSH连接到linux服务器.我试图将其作为这样的后台进程运行:

$ node server.js &

但是，在2.5小时后，终端变为非活动状态，并且该过程终止.无论如何，即使在终端断开连接的情况下，我仍然可以保持该过程正常运行吗?

实际上，我尝试了nohup，但是，一旦我关闭Putty SSH终端或拔出Internet插头，服务器进程就会立即停止.

在腻子里我有什么需要做的吗?

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

解决方案

简单解决方案(如果您对返回该过程不感兴趣，只希望它继续运行):

nohup node server.js &

还有jobs命令可以查看这些后台进程的索引列表.而且，您可以通过运行kill %1或kill %2来杀死后台进程，而数字是该进程的索引.

强大的解决方案(如果它是交互式的，则允许您重新连接到该过程):

screen

然后可以通过按Ctrl + a + d进行分离，然后通过运行screen -r

进行附加

还考虑使用屏幕替代品tmux.

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

$ node server.js &

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?

Edit 1

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

Is there anything I have to do in Putty?

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

解决方案

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

nohup node server.js &

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.

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

screen

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

Also consider the newer alternative to screen, tmux.
