1.增加服务文件

#进入系统服务目录cd /etc/systemd/system/#创建服务类型的文件vim demo.service

2.编辑内容

[Unit]Description=demoAfter=syslog.target[Service]ExecStart=/usr/local/java/jdk1.8.0_151/bin/java -jar /usr/local/project/demo.jar[Install]WantedBy=multi-user.target

只需要修改 Description 与 ExecStart 的值。

3.服务操作

#启动服务systemctl start demo#或者systemctl start demo.service#停止服务systemctl stop demo#或者systemctl stop demo.service#服务状态systemctl status demo#或者systemctl status demo.service#开机启动systemctl enable demo#或者systemctl enable demo.service#项目日志journalctl -u demo#或者journalctl -u demo.service
