Linux abandons tomcat, jar directly starts the command

(1) Check whether the jar is running

ps -ef |grep java|grep jar包名.jar

(2) Query java to run all

ps -ef |grep java

(3) Stop the jar package

kill -9 pid号

(4) Start the jar package

nohup java -jar jar包名称.jar > nohup.out 2>&1 &

(5) Start directly to see if it can be started

java -jar jar包名称.jar

When using the direct start command, this exit directly shuts down the start
