在 docker 守护进程中初始化网络控制器时出错

Question

我正在尝试通过关注Offical docs 在具有 OracleLinux 6 的虚拟服务器上安装 docker

我将内核更新到 uekr 4

#uname -r
4.1.12-61.1.19.el6uek.x86_64

这是 docker 版本

 #docker version
 Client:
 Version:      1.12.3
 API version:  1.24
 Go version:   go1.6.3
 Git commit:   6b644ec
 Built:
 OS/Arch:      linux/amd64
Cannot connect to the Docker daemon. Is the docker daemon running on this host?

当我启动守护进程时，它给出了 OK 但它立即死亡。

#service docker start
Starting docker:        .                                  [  OK  ]
#service docker status
docker dead but subsys locked

这是日志

它说没有安装包，但是当我运行sudo modinfo bridge 时，它显示了模块。我还缺少其他包吗？

我尝试在 /etc/sysconfig/docker 中设置环境变量。

我尝试通过二进制文件安装。

我尝试创建用户并将他添加到 docker 组。

我尝试了许多其他解决方案，例如

Docker service does not start

Cannot connect to docker daemon

Docker command can't connect to Docker daemon

没有任何效果！！谁能帮帮我？

我没有要测试的 Oracle Linux 6，但我相信你得到了这个 issue。有人说它在 Docker 中修复了 1.7.1 RC 但我还没有检查过。

我在 CentOS 6 或 RehHat 6 上遇到了类似的问题。我的解决方法是安装 docker-io-1.6.2-3.el6.x86_64.rpm，而不是 docker-engine。

• 下载 docker-io 包（在https://dl.fedoraproject.org/pub/epel/testing/6/x86_64/找到）
• 需要为 Docker 下载一些其他库：

编辑 yum.repos.d，请根据您的 Oracle Linux 6 进行编辑

cd /etc/yum.repos.d
wget http://www.hop5.in/yum/el6/hop5.repo
yum update

• 安装 RPM 文件并启动 Docker

这样

rpm -ivh docker-io-1.6.2-3.el6.x86_64.rpm
service docker start
