centos7 安装完docker启动时会出现的错误：Job for docker.service failed because the control process exited with error code. See “systemctl status docker.service” and “journalctl -xe” for details.导致docker没有启动成功

解决方案如下：

vim /etc/sysconfig/docker-storage

2. 将配置文件修改为：

DOCKER_STORAGE_OPTIONS="--selinux-enabled --log-driver=journald --signature-verification=false"

3. 再输入

vim /etc/docker/daemon.json

4. 写入指定参数：

{ "storage-driver": "devicemapper" }

5. 然后重启docker服务：

systemctl restart docker

查看docker启动情况

systemctl status docker

说明docker已经启动成功
