在deepin linux操作系统中安装docker-engine后启动失败。
Version: 1.12.3
API version: 1.24
Go version: go1.6.3
错误1：
使用docker ps命令报错：Cannot connect to the Docker daemon. Is the docker daemon running on this host?
使用sudo dockerd报错
WARN[0000] devmapper: Base device already exists and has filesystem xfs on it. User specified filesystem will be ignored.
INFO[0000] [graphdriver] using prior storage driver "devicemapper"
FATA[0001] Error starting daemon: timeout
ps查看进程dockerd已启动
重复使用systemctl stop/start docker 问题依然
systemctl stop docker 后，使用sudo dockerd启动无异常报错，怀疑是docker命令找不到sock，sock文件/var/run/docker.sock 权限是srw-rw----
当前用户没有权限访问，默认情况下，docker会监听 unix:///var/run/docker.sock，只允许本地的root用户连接
解决办法：
1. 将当前用户添加到docker启动组内，执行 usermod -aG docker $USER ，但root启动无效
2. root启动，有sudo权限那就 使用 sudo docker ps即可
3. 修改docker启动配置，使用TCP监听 修改/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd -H fd:// 修改为 /usr/bin/dockerd -H fd:// -H tcp://0.0.0.0:2375
重启docker
导入变量export DOCKER_HOST=tcp://localhost:2375
错误2：
docker run -d
docker: Error response from daemon: invalid header field value "oci runtime error: container_linux.go:247: starting container process caused "process_linux.go:359: container init caused \"rootfs_linux.go:53: mounting \\\"cgroup\\\" to rootfs \\\"/var/lib/docker/devicemapper/mnt/dee9d3d23be58840c31b001018f5243c62686a23a28afc009e6029747ef0a955/rootfs\\\" at \\\"/sys/fs/cgroup\\\" caused \\\"no subsystem for mount\\\"\"" ".
解决：
opencontainers/runc#1175 mentions such solution:
Change GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub so that it looks like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet systemd.legacy_systemd_cgroup_controller=yes"
quiet is from default Debian grub install.
Then update grub and reboot:
sudo update-grub
sudo reboot
