3.3 保存退出，授予tomcat文件执行权限

chmod +x tomcat
3.4 使tomcat服务生效，并使能开机自启动，然后reboot重启，即可Tomcat开机自启动生效.

sudo systemctl daemon-reload #对于新创建的unit文件或修改了的unit文件，要通知systemd重载此配置文件；
sudo systemctl enable tomcat #使能开机自启动
sudo reboot
3.5 重启后，执行systemctl status tomcat看看tomcat服务的状态。

root@localhost:~# systemctl status tomcat
