如何防止Nohup杀死等待stdin linux的java进程 [英] how to keep nohup from killing java process that waits for stdin linux

问题描述

我有一个在命令行(Bash Linux)上执行的Java程序.一旦执行，程序将继续运行，读取标准输入，直到用户输入退出".

I have a java program that is executed on command line (Bash Linux). Once executed the program continues to run, reading stdin until the user inputs 'quit'.

有时我想 nohup ，以便即使关闭远程连接，该程序也可以继续运行.问题是，当我尝试按以下所示方式对程序进行nohup时，似乎其输入stdin的提示会杀死nohup并终止该程序.

Sometimes I would like to nohup the program so it continues to run even if my remote connection is closed. The problem is that when I attempt to nohup the program as demonstrated below it seems that its prompt for stdin kills nohup and terminates the program.

示例:$ nohup java -jar myApp.jar

Example: $ nohup java -jar myApp.jar

我尝试将程序的输出重定向到其他建议 2>/dev/null ，并使用& 在后台运行它.两者都不能阻止nohup被杀死.

I have tried redirecting the program's output to 2>/dev/null per other suggestions as well as running it in the background using &. Neither prevents nohup from being killed.

我不能使用 disown ，因为一旦运行该程序，我将失去命令提示符.

I cannot use disown because once I run the program I lose the command prompt to the program.

推荐答案

要使程序在后台运行，请运行 tmux :

To get your program running in the background, run tmux:

tmux

这将打开一个tmux shell，您可以在其中运行程序:

This will open up a tmux shell, where you can run your program:

java -jar myApp.jar

然后要从tmux会话中分离，请键入 ctrl-b ，然后键入 d .您的程序将继续在后台运行.

Then to detach from the tmux session, type ctrl-b then d. Your program will continue to run in the background.

要在以后重新连接到程序的外壳(杀死它或查看其输出)，请运行 tmux attach .

To reattach to your program's shell at a later time (to kill it or view its output), run tmux attach.
