参照这篇博客:在Ubuntu 18.04上安装Tomcat 8 并设置自启动 成功了。
但是期间遇到了一个问题:运行命令sudo systemctl start tomcat的时候,报错:
Warning: The unit file, source configuration file or drop-ins of tomcat.service changed on disk. Run 'systemctl daemon-reload' to reload units.
Job for tomcat.service failed because the control process exited with error code.
See "systemctl status tomcat.service" and "journalctl -xe" for details.
使用命令:systemctl status tomcat ,查看状态:
Warning: The unit file, source configuration file or drop-ins of tomcat.service changed on disk. Run 'systemctl daemon-reload' to reload units.

根据No such process,我猜测是tomcat.service文件权限不够,查看,果然是只读:
-rw-r--r-- 1 root root 694 2月 15 00:45 tomcat.service
提升权限后重新启动tomcat服务,成功,最后设置开机自启动。
sudo chmod 777 tomcat.service
