CentOS7 启动docker.service失败

Question

Hi all:
在CentOS7上执行yum install docker安装docker后，对docker进行测试出现如下错误：

[root@localhost /]# docker run -i -t ubuntu /bin/bash
2014/11/27 15:21:52 Post http:///var/run/docker.sock/v1.14/containers/create: read unix /var/run/docker.sock: connection reset by peer

搜索后得知是没有启动docker服务，执行启动服务失败：

[root@localhost /]# systemctl start docker.service
Job for docker.service failed. See 'systemctl status docker.service' and 'journalctl -xn' for details.
[root@localhost /]# systemctl status docker.service

Anda perlu memasang device-mapper-event-libs dan kemudian ia berfungsi. Hanya lakukan sudo yum install device-mapper-event-libs selepas anda memasang docker.

Answer 2

yum install device-mapper-event-libs

Nampaknya saya telah mengubah suai /etc/selinux/config sebelum ini dan menukar SELINUX=enforced kepada SELINUX=disabled. Cuma tukar balik
