How to start jar package and run it in the background in Linux

The Linux command to run the jar package is as follows:

Method 1:

java -jar shareniu.jar

Features: The current ssh window is locked. You can press CTRL + C to interrupt the program, or close the window directly to exit the program.

How to prevent the window from locking?

Method 2

java -jar shareniu.jar &

& represents running in the background.

Specific: The current ssh window is not locked, but when the window is closed, the program terminates.

Continue to improve, how to make the program still running when the window is closed?

Method 3

nohup java -jar shareniu.jar &

nohup means running the command without interruption. When the account is logged out or the terminal is closed, the program will still run.

When a job is executed with the nohup command, all output of the job is redirected to the nohup.out file by default unless an output file is specified otherwise.

Method 4

nohup java -jar shareniu.jar >temp.txt &

Explain>temp.txt

command >out.file

command >out.file redirects the output of command to the out.file file, that is, the output content is not printed on the screen, but output to the out.file file.

You can view background running tasks through the jobs command

jobs

Then all the background jobs will be listed, and each job will be preceded by a number.
If you want to call a job back to the foreground control, just use fg + the number.

fg 23

View the pid of the thread occupying a port

netstat -nlp |grep :9181

If you forget the process ID, you can use the following command to view the process ID of the currently running jar package program

ps -ef|grep xxx.jar


Or ps -aux | grep java

//Close the process

kill -s 9 24204

24204 represents the process ID found in the previous step
