CentOS6.5安裝docker

先用CentOS6.5安裝docker-io學習着，什麼歷史、優點、特色先不扯了。

升級內核

yum安裝帶aufs模塊的3.10內核

[root@docker-machine_192.168.31.129 ~]# cd /etc/yum.repos.d 
[root@docker-machine_192.168.31.129 ~]# wget http://www.hop5.in/yum/el6/hop5.repo
[root@docker-machine_192.168.31.129 ~]# yum clean all
[root@docker-machine_192.168.31.129 ~]# yum install -y kernel-ml-aufs kernel-ml-aufs-devel

修改grub：

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/sda2
#          initrd /initrd-[generic-]version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu

重啓

查看內核：

[root@docker-machine_192.168.31.129 ~]# uname -r
3.10.5-3.el6.x86_64

安裝docker

epel源：

yum -y install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

安裝docker:

yum install -y docker-io

修改docker root：

[root@docker-machine_192.168.31.129 ~]# mv /var/lib/docker /data/
[root@docker-machine_192.168.31.129 ~]# ln -sv /data/docker /varlib/docker
`/data/docker' -> `/varlib/docker'
#或者：
[root@docker-machine_192.168.31.129 ~]# cat /etc/docker/daemon.json 
{
  "data-root" : "/data/dokcer",
}

啓動：
[root@docker-machine_192.168.31.129 ~]# /etc/init.d/docker start 
Starting docker:                                           [  OK  ]

瞄一眼：

[root@docker-machine_192.168.31.129 ~]# docker version
