Start nodejs app on linux server with ssh-if i close the ssh connection,app stopped why?)

Question

用ssh在linux服务器上启动nodejs应用程序（如果我关闭ssh连接，应用程序停止了吗？）1-创建nodejs应用程序-它的功能2-在Linux服务器上运行-它的功能（我停止了Apache服务器）但是如果我关闭了SSH连接（与我的Windows PC），应用程序停止。我该如何解决此问题？

Answer 1

Use the nohup command to start the application. Like:

nohup THE_COMMAND_YOU_DONT_WANT_TO_STOP_WHEN_YOU_LOGOUT &

With nodemon it might be helpful to put the command to start the server in a file called myserver.sh containing:

nodemon server.js

Make sure the file is executable:

chmod +x myserver.js

And then run

nohup myserver.sh &

Answer 2

The most correct thing to do is to write a service file for it so whatever init system you have (likely systemd) will keep it running and manage the start/stop/restart stuff for you.

Failing that (and I don't blame you...) you can run it within the screen utility. Launch it with screen -d -m /path/to/start/script and then you can come back later and reconnect to it with screen -r or screen -r <pid of the screen session> .

Note that launching it that way won't restart it, etc. To do that, you could do something like

#!/bin/sh

while true
do
 sleep 3s
 /path/to/start/script
done

And call that with the screen command.
