在服务器上运行 java jar 文件作为后台进程 [英] Run java jar file on a server as background process

问题描述

我需要在服务器中运行一个 java jar 以便在两个应用程序之间进行通信.我已经编写了两个 shell 脚本来运行它，但是一旦我启动了该脚本，我就无法关闭/终止该进程.如果我按 ctrl+C 或关闭控制台，服务器将关闭.谁能帮我修改这个脚本以作为普通服务器运行?

I need to run a java jar in server in order to communicate between two applications. I have written two shell scripts to run it, but once I start up that script I can't shut down / terminate the process. If I press ctrl+C or close the console, the server will shut down. Could anyone help me how to modify this script to run as a normal server?

 #!/bin/sh
java -jar /web/server.jar
echo $! 
#> startupApp.pid

推荐答案

你可以试试这个:

#!/bin/sh
nohup java -jar /web/server.jar &

&符号，切换程序在后台运行.

The & symbol, switches the program to run in the background.

即使在您注销后，nohup 实用程序也会使作为参数传递的命令在后台运行.

The nohup utility makes the command passed as an argument run in the background even after you log out.
