The best way to start a jar package project under Centos7 server

Preface

Everyone knows how to run a jar package on Linux. Why do I want to talk about it separately? Careful friends may have discovered the keywords Centos7 and best way in the title.

This shows that I am not just writing something casually to write a blogヾ(◍°∇°◍)ﾉﾞ

First of all, Centos7 recommends that we run the project like this

First execute the command:

cd /ets/systemd/system

Go to this directory and create a new file yourProjectName.service. You can set yourProjectName to the service name you want.

Edit a new file with vi

vi yourProjectName.service

file name

[Unit] 
Description=yourProjectName #DescriptionAfter=syslog.target network.target #Depends on [Service] 
Type=simple 

ExecStart=/usr/bin/java -jar /opt/javaapps/yourProjectName.jar 
#The first part is the absolute path of the java command and the second part is the absolute path of the jar package. ExecStop=/bin/kill -15 $MAINPID 

User=root 
Group=root 

[Install] 
WantedBy=multi-user.target

use

systemctl start yourProjectName

or

systemctl start yourProjectName.service

The service is started.

If you change the project:

Run first

systemctl daemon-reload

Then run systemctl start sell.service

To stop the service:

systemctl stop yourProjectName

or

systemctl stop yourProjectName.service

Set the startup to start automatically:

systemctl enable yourProjectName

or

systemctl enable yourProjectName.service

Or if you don't want to start the machine:

systemctl disable yourProjectName

or

systemctl disable yourProjectName.service

Okay, that's all. Running the project in a standardized manner helps with later maintenance.
