Question

我正在尝试启动Docker守护程序：

sudo systemctl start docker

但没有任何反应，光标只是闪烁，过程永远不会结束。

昨天它运作正常:(

sudo journalctl -fu docker

Answer 1

systemd的一个有趣的事情是，如果它认为守护程序正在运行，那么start命令什么都不做。

我必须执行以下操作以确保干净地重启某些守护进程：

sudo systemctl stop service-name

# wait a little if the service is slow to stop like the Cassandra database

sudo systemctl start service-name

这对我有各种各样的服务。

了解服务是否被视为正在运行的一种方法是检查状态如下：

systemctl status service-name

Docker守护程序无法启动
