Write a general shell script to start a java project, which is applicable to most services. You only need to modify the service name
File name: service user sh
Document content:
##The header file of shell script must have #/ bin/sh
##Configure the Java environment variable again to avoid reporting other errors ## Java env#jdk installation directory export Java_ HOME=/usr/java/jdk1. 8.0_ 144export JRE_ HOME=$JAVA_ HOME/jre
## service nameAPP_ NAME=user
##Service folder_ DIR=/service/$APP_ Name ## service name service_ NAME=edu-service-$APP_ Name ##jar package name jar_ NAME=$SERVICE_ NAME\. Jar ## generate process file PID = $service_ NAME\. pid
##Enter the service storage folder CD $service_ DIR
##Receive a parameter input from the Linux console/ service-user. sh start/stop/restartcase "$1" in
##When the input parameter is start, start the project (start) ##nohup daemon starts the project, and the project is still running even after exiting the terminal/ Dev / null inputs the log to null, that is, it does not output the log to notout Out, because there are already log4j logs in the project.
