验证一下是否为开机启动

systemctl is-enabled fprintd
static

systemctl简单应用，开启自启动、停止、重启

查看服务是否开机启动： systemctl is-enabled postfix.service

查看已启动的服务列表： systemctl list-unit-files | grep enabled

查看启动失败的服务列表： systemctl --failed
PS：使用命令 systemctl is-enabled postfix.service 得到的值可以是enable、disable或static，这里的 static 它是指对应的 Unit 文件中没有定义[Install]区域，因此无法配置为开机启动服务。

1 查看指定的服务是否开机自动启动
2 systemctl list-unit-files | grep nginx.service
3 systemctl list-unit-files nginx.service
4 systemctl is-enabled nginx.service
5 查看一个unit的依赖关系：systemctl list-dependencies nginx.service
6 优先用reload，如果无法让修改生效，才执行restart：systemctl reload-or-restart nginx.service

systemctl list-dependencies fprintd.service
