服务器（CentOS）重启后，发现Docker启动不起来了

[root@iZ2ze9d5m6vjfbqzb49i5qZ ~]# systemctl start docker
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

按照提示，使用systemctl status docker.service查看容器状态

[root@iZ2ze9d5m6vjfbqzb49i5qZ ~]# sudo systemctl status docker.service

发现关键报错，unable to configure the Docker daemon with file /etc/docker/daemon.json: json: cannot unmarshal s…[]string，但是好像又没有显示全，加上-l参数查看详细信息

[root@iZ2ze9d5m6vjfbqzb49i5qZ ~]# sudo systemctl status docker.service -l

发现了关键报错信息，我们配置的docker镜像写法错误

unable to configure the Docker daemon with file /etc/docker/daemon.json: json: cannot unmarshal string into Go struct field Config.registry-mirrors of type []string

于是修改daemon.json配置文件

vi /etc/docker/daemon.json

之前的写法为：

{"registry-mirrors":"https://docker.mirrors.ustc.edu.cn","live-restore":true}

修改后为

{"registry-mirrors":["https://docker.mirrors.ustc.edu.cn"],"live-restore":true}

错误解决
