Linux under Docker installation

1 installing Docker Docker on CentOS 6.4 currently only supports Ubuntu, so installing Docker on CentOS is a hassle (Issue #172). The official Docker document says Linux kernel is required to be at least 3.8 and CentOS 6.4 is the 2.6 kernel, so I whined whined to install the latest kernel 3.11.6, reboot and run Docker or fail, and finally find the reason is because the compile-time forgot to integrate the Aufs module.   Aufs need to compile with kernel, very troublesome. But no need to be so troublesome, a strongman has compiled the kernel with AUFS module, see here Installing Docker.io on CentOS 6.4 (64-bit)

1.1 Cancel SELinux because it interferes with the normal function of lxc sudo vim/etc/selinux/config selinux=disabled selinuxtype=targeted

1.2 Installing Fedora EPEL sudo yum install http://ftp.riken.jp/Linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm

1.3 Add HOP5 repo address cd/etc/yum.repos.d sudo wget http://www.hop5.in/yum/el6/hop5.repo

1.4 Installing the Docker-io sudo yum install docker-io automatically installs the 3.10 cores with the Aufs module, as well as the Docker-io package.

1.5 Add the Cgroup file system to the/etc/fstab so that Docker works correctly sudo echo "None/sys/fs/cgroup cgroup def Aults 0 0 ">>/etc/fstab

1.6 Modify Grub Boot order sudo vim/etc/grub.conf default=0 set default to the location of the newly installed kernel, typically 0

1.7 Restarting Sudo reboot

1.8 Check if the new kernel is booting successfully, check to see if the new kernel is booting up uname-r 3.10.5-3.el6.x86_64 instructions succeeded look at Aufs there is grep aufs/proc/filesystems nod EV Aufs Description exists

1.9 Starting the Docker daemon process sudo docker-d & if you are in the company and the company is online via proxy, you can tell Docker the proxy server using the following command (see here): sudo http_proxy=http: Xxx:port docker-d &

1.10 Download Ubuntu image sudo docker pull Ubuntu

1.11 Run Hello World sudo docker run ubuntu/bin/echo Hello World Hello World installation succeeded!!
