您需要阅读命令的输出（以及您仔细发布的内容），您似乎错过了
varnish.service 的作业失败，因为控制进程以错误代码退出。请参阅“systemctl 状态 varnish.service“ 和 ”journalctl-xe”以了解详细信息。
上面这一行是解决这个问题的关键。特别是你应该运行以下命令
systemctl status varnish.service
可能会提供一些有用的信息（但也可能没有）
systemctl status varnish.service
这将提供有用的信息。
注意你可能应该运行
systemctl start varnish.service
然后运行错误消息中的命令。
