1.升级系统的内核

1 2 3

cd  /etc/yum.repos.d/ wget http://www.hop5.in/yum/el6/hop5.repo yum install kernel-ml-aufs kernel-ml-aufs-devel  -y

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

default=0 set to 0 and check Centos &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& [iyunv@oldboy ~]# vim /etc/grub.conf # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes tothis file # NOTICE:  You have a /bootpartition.  This means that #          all kernel andinitrd paths are relative to /boot/, eg. #          root (hd0,0) #          kernel/vmlinuz-version ro root=/dev/sda3 #          initrd/initrd-[generic-]version.img #boot=/dev/sda default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (3.10.5-3.el6.x86_64)         root (hd0,0)         kernel/vmlinuz-3.10.5-3.el6.x86_64 ro root=UUID=7b76340c-8d26-421c-b2bb-802770973f88rd_NO_LU KS rd_NO_LVM.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16crashkernel=auto  KEYBOARDTYPE=pc KEY TABLE=us rd_NO_DM rhgb quiet         initrd/initramfs-3.10.5-3.el6.x86_64.img title CentOS 6 (2.6.32-573.el6.x86_64)

1 2 3 4 5 6 7 8

然后重启 reboot 检查系统内核： [iyunv@oldboy ~]# uname -r 3.10.5-3.el6.x86_64 查看内核是否支持aufs [iyunv@oldboy ~]# grep aufs /proc/filesystems nodev   aufs

2.关闭selinux

1 2 3 4

[iyunv@oldboy ~]# getenforce Disabled 没有的话关闭selinux sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config

3.安装docker

1 2 3

在Fedora EPEL源中已经提供了docker-io包，下载安装epel： rpm -ivh http://mirrors.sohu.com/fedora-e ... ease-6-8.noarch.rpm sed -i 's/^mirrorlist=https/mirrorlist=http/' /etc/yum.repos.d/epel.repo

4.yum 安装docker-io

1	yum -y install docker-io

5.启动Docker

1 2 3 4

[iyunv@oldboy ~]# service docker start Starting cgconfig service:                                 [确定] Starting docker:                                           [确定] [iyunv@oldboy ~]#

6.查看docker的版本

1 2 3 4 5 6 7 8 9 10 11 12

[iyunv@oldboy ~]# docker  version Client version: 1.7.1 Client API version: 1.19 Go version (client): go1.4.2 Git commit (client): 786b29d/1.7.1 OS/Arch (client): linux/amd64 Server version: 1.7.1 Server API version: 1.19 Go version (server): go1.4.2 Git commit (server): 786b29d/1.7.1 OS/Arch (server): linux/amd64 [iyunv@oldboy ~]#

7.查看Docker的日志

1 2 3 4 5 6 7 8 9 10 11 12

[iyunv@oldboy ~]# cat /var/log/docker \n2016年 08月 02日星期二 17:08:53 CST\n time="2016-08-02T17:08:53.628209179+08:00" level=info msg="Listening for HTTP on unix (/var/run/docker.sock)" time="2016-08-02T17:08:53.765733247+08:00" level=warning msg="Running modprobe bridge nf_nat failed with message: insmod /lib/modules/3.10.5-3.el6.x86_64/kernel/net/llc/llc.ko \ninsmod /lib/modules/3.10.5-3.el6.x86_64/kernel/net/802/stp.ko \ninstall /sbin/modprobe --ignore-install bridge && /sbin/sysctl -q -w net.bridge.bridge-nf-call-arptables=0 net.bridge.bridge-nf-call-iptables=0 net.bridge.bridge-nf-call-ip6tables=0\ninsmod /lib/modules/3.10.5-3.el6.x86_64/kernel/net/bridge/bridge.ko \ninsmod /lib/modules/3.10.5-3.el6.x86_64/kernel/net/netfilter/nf_conntrack.ko \ninsmod /lib/modules/3.10.5-3.el6.x86_64/kernel/net/netfilter/nf_nat.ko \n, error: exit status 1" time="2016-08-02T17:08:54.018750099+08:00" level=warning msg="Your kernel does not support swap memory limit." time="2016-08-02T17:08:54.019550061+08:00" level=info msg="Loading containers: start."    time="2016-08-02T17:08:54.019778904+08:00" level=info msg="Loading containers: done." time="2016-08-02T17:08:54.019801548+08:00" level=info msg="Daemon has completed initialization" time="2016-08-02T17:08:54.019823924+08:00" level=info msg="Docker daemon" commit="786b29d/1.7.1" execdriver=native-0.2 graphdriver=aufs version=1.7.1 time="2016-08-02T17:10:12.131694594+08:00" level=info msg="GET /v1.19/version" [iyunv@oldboy ~]#
