docker 解决：Get http:///var/run/docker.sock/v1.19/version: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS?

docker 安装之后，通过命令查看docker相关信息时，可能会出现错误：Get http:///var/run/docker.sock/v1.19/version: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS?

通过命令重启docker时又会出现另一个错误：

查看服务状态时又出现：

服务无法正常停止或重启，可能就是系统环境出现了问题，google一下发现一篇文章的解决方案：

You may have to enable the public_ol6_latest repo in order to get this package.

sudo yum-config-manager --enable public_ol6_latest

And then install the package:

sudo yum install device-mapper-event-libs

测试一下：

重启启动服务，查看一下服务状态：

docker 服务正常运行了。
