Docker启动报Job for docker.service failed because the control process exited with error code. See “syst

由于我的Docker是装在虚拟机上，由于电脑长时间未关机太卡，于是今天重启了一下机器，但是Docker未重启，于是就执行了一遍systemctl restart docker.service 然后就出现了Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

通过systemctl status docker.service查看docker状态

查看状态发现提示无法启动Docker的程序引擎，此时就想到了前几天配置了一下镜像加速器 ，通过 vim /etc/docker/daemon.json
查看json是否有错误，果不其然单词拼错了
