docker17.09.1-ce 执行systemctl resart docker重启失败的问题

记录在实际操作中碰到的docker问题

环境信息：

安装完kolla ocata版本，并且编译成功各openstack 组件的容器镜像

[[email protected] ~]# docker --version
Docker version 17.09.1-ce, build 19e2cf6

[[email protected] ~]# uname -a

Linux localhost.localdomain 3.10.0-514.el7.x86_64 #1 SMP Tue Nov 22 16:42:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
[[email protected] ~]#

问题上下文：

执行systemctl restart docker命令，提示如下错误信息

[[email protected] ~]# 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.

查看journalctl -xe|grep docker信息，报如下错误

问题解决方式：

1)卸载Docker安装包

yum remove docker*

2)清空/var/lib/docker/目录的内容(这一步必须做)

rm -rf /var/lib/docker/

3)重新安装docker

yum -y install docker-ce-17.09.1.ce

4)启动docker并查看安装的docker版本

systemctl enable docker

systemctl daemon-reload #这步是必须的，重新加载docker.service文件的配置，否则重启也是启动之前的配置。

systemctl start docker
