1、编写*.service文件
[Unit]
Description=esbservice
[Service]
WorkingDirectory=/opt/app/test
ExecStart=/usr/bin/java -jar /opt/app/test/XXX-3.0.jar &
User=root
Type=simple
Restart=on-failure
RestartSec=10
[Install]
WantedBy=multi-user.target
2、启动程序是否正常
systemctl start esbservice.service
3、查看状态
systemctl status esbservice.service
4、自启动程序
sudo systemctl enable esbservice.service
5、重启服务器后，查看并验证程序自启是否成功
systemctl status esbservice.service
6、常用systemctl 命令
启动sshd服务：systemctl start ssh.service
停止sshd服务：systemctl stop ssh.service
查看sshd服务状态：systemctl status ssh.service
重启sshd服务：systemctl restart ssh.service
设置开机自启动：systemctl enable ssh.service
禁止开机自启动：systemctl disable ssh.service
查看所有已经启动的服务：systemctl list-units --type=service
重新加载配置文件：systemctl daemon-reload
