一、升级内核

将版本为2.6.32-431.el6.x86_64的内核升级为3.10.5-3.el6.x86_64

1、安装autfs相关软件执行升级操作

[root@linux-node1 yum.repos.d]# yum install kernel-ml-aufs kernel-ml-aufs-devel

2、修改内核默认启动顺序:

default=1

timeout=5

splashimage=(hd0,0)/grub/splash.xpm.gz

改为:

default=0

timeout=5

splashimage=(hd0,0)/grub/splash.xpm.gz

最终结果为:

#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=5209c50c-75cb-479d-8cb3-2a60f6c2141f rd_NO_LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto  KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet

        initrd /initramfs-3.10.5-3.el6.x86_64.img

以上步骤操作完之后，重启系统确认内核版本

[root@linux-node1 ~]# uname -r

3.10.5-3.el6.x86_64

[root@linux-node1 ~]# grep aufs /proc/filesystems

nodev   aufs

[root@linux-node1 ~]# 

二、安装docker

3、安装docker

[root@linux-node1 opuser]# yum  install docker-io -y

4、启动docker

[root@linux-node1 ~]# /etc/init.d/docker start

Starting docker:        [  OK  ]

[root@linux-node1 ~]#

5、查看启动状态:

[root@linux-node1 ~]# /etc/init.d/docker status

docker (pid  1242) is running...

[root@linux-node1 ~]#

6、查看日志:

\nSun May 22 07:43:13 CST 2016\n

time="2016-05-22T07:43:13.450506633+08:00" level=info msg="Listening for HTTP on unix (/var/run/docker.sock)"

[root@linux-node1 ~]# 

7、如果docker启动失败，而且日志中出现如下内容:

[root@linux-node1 ~]# cat /var/log/docker 

\nSun May 22 07:41:07 CST 2016\n

/usr/bin/docker: relocation error: /usr/bin/docker: symbol dm_task_get_info_with_deferred_remove, version Base not defined in file libdevmapper.so.1.02 with link time reference

[root@linux-node1 ~]#

则需要安装: device-mapper-libs库

[root@linux-node1 ~]# yum upgrade device-mapper-libs

至此将centos6.5内核从2.6.32-431.el6.x86_64升级到3.10.5-3.el6.x86_64
