Centos 下安装Docker 遇到的一些错误

1.公司的服务器的内核版本：2.6.32-431.23.3.el6_x86_64

如何升级内核请参考前一篇文章

2.在这个地址上面下载 的 https://test.docker.com/builds/Linux/x86_64/docker-1.10.0

这个是最新的docker

但是没有配置文件

下载下来直接就可以用了

把它放到 cp .. /usr/bin/docker

docker deaemon 这样启动

[root@MMD-GEN ~]# docker daemon

报了个错

这个错误为cgroup在宿主机上没有挂载。
我们编辑挂载上去

vi /etc/fstab
#在结尾添加
none        /sys/fs/cgroup        cgroup        defaults    0    0

然后执行reboot重启服务器。

然后，世界又再一次的安静了
