Docker application container on centos6 system

You only need to perform the following operations:
1. # cd/etc/yum. repos. d/
# Wget-O/etc/yum. repos. d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
# Rpm-ivh http://mirrors.aliyun.com/epel/6Server/x86_64/epel-release-6-8.noarch.rpm
2. yum update

# Yum clean all & yum makecache & yum update-y
3. Install docker and start the docker service
# Yum install docker-io
# Service docker start

However, such a docker file system is faulty,

Note: Data file:/dev/loop0. docker's file storage adopts the loop block device mode for mounting, reading, and writing. It will be very troublesome to resize in the future.

So the operation is performed after Kernel 3.10 is upgraded.

Upgrade the kernel in four steps:

# Cd/etc/yum. repos. d
# Wget http://www.hop5.in/yum/el6/hop5.repo
# Yum install kernel-ml-aufs-devel-y
# Modify grub. conf to start kernel 3.10 & reboot

Continue!
