Centos6.5 install docker

1. Upgrade CentOS 6.5 kernel to 3.10.28

1. Import public key

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

2. Install ELRepo to CentOS-6.5

rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm

3. Install kernel-lt (lt=long-term)

yum --enablerepo=elrepo-kernel install kernel-lt -y

4. Edit the grub.conf file and modify the Grub boot order

vim /etc/grub.conf
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that
# all kernel and initrd paths are relative to /, eg.
# root (hd0,0)
#          kernel /boot/vmlinuz-version ro root=/dev/sda1
#          initrd /boot/initrd-[generic-]version.img
#boot=/dev/sda
default=0
timeout=5

Confirm the location of the newly installed kernel, and then set the default value (starting from 0). Generally, the newly installed kernel is in the first location, so set default=0.

5. Restart and check the kernel version number

[root@dev ~]# uname -r
3.10.28-1.el6.elrepo.x86_64

2. An error occurred:
docker: symbol dm_task_get_info_with_deferred_remove, version Base not defined in file libdevmapper.so.1.02 with link time reference

Solution:
yum upgrade device-mapper-libs

3. An error occurred:
WARN[0000] Your kernel does not support cgroup memory limit: mountpoint for memory not found
WARN[0000] mountpoint for cpu not found                
FATA[0000] Error mounting devices cgroup: mountpoint for devices not found

solution:
The cgroup is not mounted on the host.
vim /etc/fstab
add
none /sys/fs/cgroup cgroup defaults 0 0
to restart the machine

4. A warning appears:
WARN[0000] Running modprobe bridge nf_nat failed with message: , error: exit status 1
