1.
BUILD_ID=dontKillMe nohup ./yourStartScript.sh &
不确定是否有效
2.
Add this line as a JAVA_ARGS argument when you start your jenkins server (I put mine on /etc/default/jenkins in my Ubuntu box)
-Dhudson.util.ProcessTree.disable=true
Centos 里面可能是/etc/sysconfig/jenkins

By default, Jenkins will kill all the spawned process at the completion of build.
To override this, you need to create environment variable BUILD_ID.
Go to Jenkins-->Manage Jenkins-->Configure System Now under 'Global properties' section, under Environment variables, click on ADD button to add new Environment variable. Give Name= BUILD_ID and value='allow_to_run_as_daemon start_my_service' (without quote). Click on save button. And you are done.
Now the spawn process will continue to execute even after the build got completed.
这个试验后有效。
