Run a java application in background on Debian with logback and nohup

Question

I have some apps that are packaged as executable jar files. Now I added logback logging with file appender to the app. The problem is I run those apps on server with this command:

nohup java -jar app.jar &

nohup.out captures all outputs and ruins the whole purpose of rotating log files and separate error and info log. I'd rather not to run my app as a service (There are lots of it) so wondering if there is a way to execute the jar in the background infinitely and have the logback logging to the files defined in logback.xml This is my logback.xml file if it helps:

<configuration debug="true">

Answer 1

您需要将配置文件传递到登录系统。

 nohup java -jar app.jar -DLogback.configurationFile=/path/to/Logback.xml &

Answer 2

我认为执行此操作的方法之一是这样的：

nohup setsid java -jar app.jar -Dparams=xyz </dev/null >/dev/null 2>&1 &
