1. 创建 Service
/lib/systemd/system 目录下创建 tomcat.service 文件：
[Unit] Description=Tomcat service. [Service] Type=forking ExecStart=/home/startup.sh ExecReload=/bin/kill -SIGHUP $MAINPID ExecStop=/home/shutdown.sh [Install] WantedBy=multi-user.target graphical.target
tomcat.service 核心就是 startup.sh、shutdown.sh 脚本，添加完后需重新加载配置、设置开机自启动等：
# 设置可执行权限 sudo chmod +x ./startup.sh sudo chmod +x ./shutdown.sh # 重新加载配置 sudo systemctl daemon-reload # 启动服务 systemctl start tpqxb.service # 服务常用操作（当然配置里需要支持才行） systemctl start tomcat.service systemctl stop tomcat.service systemctl restart tomcat.service systemctl status tomcat.service
2. 删除 Service
systemctl stop [servicename] systemctl disable [servicename] rm /etc/systemd/system/[servicename] rm /etc/systemd/system/[servicename] # and symlinks that might be related rm /usr/lib/systemd/system/[servicename] rm /usr/lib/systemd/system/[servicename] # and symlinks that might be related systemctl daemon-reload systemctl reset-failed
It is possible that the systemd service ‘wraps’ the old style scripts in /etc/init.d, so you may want to clean that up too, but that is not where systemd services live.
