1.新增**.service配置文件

vim /etc/systemd/system/test.service

2.写入配置

[Unit] Description=test service [Service] WorkingDirectory=/usr/local/project/ PrivateTmp=true Restart=always Type=simple ExecStart=/usr/java/jdk1.8.0_231-amd64/bin/java -Xmx1024m -Xms512m -Xss256k -jar /usr/local/project/test.jar ExecStop=/usr/bin/kill -15 $MAINPID [Install] WantedBy=multi-user.target

########配置参数描述如下： ########################################################

[Unit]

Description=test service       #要设置的服务名：test

[Service]

WorkingDirectory=/usr/local/project/      #jar存放的位置 /usr/local/project/

PrivateTmp=true

Restart=always

Type=simple

ExecStart=/usr/java/jdk1.8.0_231-amd64/bin/java -Xmx1024m -Xms512m -Xss256k -jar /usr/local/project/test.jar   #java绝对路径 项目的绝对路径

ExecStop=/usr/bin/kill -15 $MAINPID

[Install]

WantedBy=multi-user.target

###################################################################################

3.重新载入systemd

systemctl daemon-reload

4.查看服务状态

systemctl status test #test服务名

5.其他常用命令

systemctl start test #启动服务 systemctl stop test #停止服务 systemctl reload test #重新加载

6.设置开机自启

systemctl enable test

7.取消开机自启

systemctl disable test
