## 1、启动docker ##

systemctl restart docker.service

报错后用以下命令查看docker状态  
root@X555LB:~\# systemctl status docker.service  
● docker.service - Docker Application Container Engine  
Loaded: loaded (/lib/systemd/system/docker.service; disabled; vendor preset: enabled)

4月 28 18:52:57 X555LB systemd\[1\]: Failed to start Docker Application Container Engine.

## 2、运行dockerd命令 ##

root@X555LB:~\# dockerd  
报错，大概意思是docker支持的有效存储驱动有devicemapper, overlay2，可能docker默认的存储驱动不是这两个，更改为有效的存储驱动即可。  
Error starting daemon: error initializing graphdriver: /var/lib/docker contains several valid graphdrivers: devicemapper, overlay2; Please cleanup or explicitly choose storage driver (-s )

## 3、更改存储驱动 ##

gedit /etc/docker/daemon.json

{
    "registry-mirrors": ["https://2elq31uu.mirror.aliyuncs.com"],
    "storage-driver": "devicemapper"
    }

4、重启docker即可

systemctl restart docker.service
