docker安装升级linux内核(2.6.32->3.10.81)

.内核升级环境准备

#查看已经安装的和未安装的软件包组，来判断我们是否安装了相应的开发环境和开发库； 
yum grouplist 
#一般是安装这两个软件包组，这样做会确定你拥有编译时所需的一切工具 
yum groupinstall "Development Tools" 
#你必须这样才能让 make *config 这个指令正确地执行 
yum install ncurses-devel 
#如果你没有 X 环境，这一条可以不用 
yum install qt-devel 
#创建 CentOS-6 内核时需要它们 
yum install hmaccalc zlib-devel binutils-devel elfutils-libelf-devel

 

2.开始升级内核：

 cd /usr/src/linux-3.10.81
 #复制原内核配置 
 cp /boot/config-2.6.32-71.el6.x86_64 .config 
 vim .config
 /*将如下内容 追加入.config 并保存
    CONFIG_NF_NAT_IPV4=y
    CONFIG_IP_NF_TARGET_MASQUERADE=y
    CONFIG_NETFILTER_XT_MATCH_ADDRTYPE=y
    CONFIG_MEMCG_SWAP=y
    CONFIG_MEMCG_SWAP_ENABLED=y
    CONFIG_AUFS_FS=y
    CONFIG_DM_THIN_PROVISIONING=y
    CONFIG_OVERLAY_FS=y
    CONFIG_CGROUP_PERF=y
    CONFIG_CFS_BANDWIDTH=y
    HYPERVISOR_GUEST=y
    CONFIG_VMWARE_BALLOON=m
 */
 #编辑内核配置，开启内核CGROUP支持
 make menuconfig
 #选择General setup-->Control Group support->Memory Resource Controller for Control Groups选中
 #自动整理.config
 sh -c 'yes "" | make oldconfig'
 #编译并安装内核(j8代表8个线程同时编译，请根据你的机器情况设置）
 make -j8 bzImage && make -j8 modules && make -j8 modules_install && make install
 vim /etc/grub.conf 
 修改default=0保存。即选择从你新编译的内核启动linux。
 #重启
 reboot 

 #注意：重新编译内核请运行
 cd /usr/src/linux-3.10.81
 make mrproper
 make clean

3.安装docker

#启动后
uname -r
返回3.10.81表示内核安装并启动成功
#rehl的docker安装说明https://docs.docker.com/installation/rhel/
#如下是安装说明的简化：
#a.下载docker的rpm
wget https://get.docker.com/rpm/1.7.0/centos-6/RPMS/x86_64/docker-engine-1.7.0-1.el6.x86_64.rpm
#本地安装rpm包
 sudo yum localinstall --nogpgcheck docker-engine-1.7.0-1.el6.x86_64.rpm
#启动docker服务
sudo service docker start 这里等价于docker -d 

#如果要追加参数请修改/etc/sysconfig/docker 这个文件 如：加入other_args=" -s vfs"
-s 是指定使用的文件系统，默认是devicemapper 也可以是vfs 或aufs(ubuntu的）
我的在这里使用默认的devicemapper没有启动成功。请看FAQ#
#运行docker的最简镜像
docker run hello-world

#docker image/ps/search/pull 等等正常就成功了
#登入容器
docker exec -ti 26723dc2509a /bin/bash

4.FAQ有两个问题还没有解决

ERRO[0000] [graphdriver] prior storage driver "devicemapper" failed: exit status 1
FATA[0000] Error starting daemon: error initializing graphdriver: exit status 1
出现上述错误有如下解决办法！
*1. yum upgrade device-mapper-libs 再次启动看是否可以
2. 使用另一种文件系统试一下如：docker -d -s vfs 默认是devicemapper系统 还可以使用aufs
3.#至此如果还是没有启动docker-daemon守护服务，那就用下面的方法把docker版本降低试下*。
*并在/etc/yum.repos.d/hop5.repo中添加yum源内容*
[hop5]                                             
name=www.hop5.in Centos Repository                 
baseurl=http://www.hop5.in/yum/el6/                
gpgcheck=0                                         
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-HOP5    
保存并更新cache
yum makecache
安装docker-io
yum install docker-io
再次运行
docker -d 
成功！
**上面第3步，启动docker-daemon不成功，可能是我的线上机器是虚拟机的问题所以加上 -s vfs 就启动成功了。**

##宿主机不能正常ping容器的ip
注意宿主（host)的iptables设置。

##ip netns “Object "netns" is unknown, try "ip help".
'”报错错误 请安装如下包:
wget https://repos.fedorapeople.org/openstack/EOL/openstack-grizzly/epel-6/iproute-2.6.32-130.el6ost.netns.2.x86_64.rpm

5.安装aufs文件系统

cd /etc/yum.repos.d 
wget http://www.hop5.in/yum/el6/hop5.repo 
yum install kernel-ml-aufs 
docker -d -s aufs #使用aufs文件系统启动docker服务

快速安装方法

sudo yum install -y http://vault.centos.org/6.6/os/x86_64/Packages/device-mapper-libs-1.02.90-2.el6.x86_64.rpm http://vault.centos.org/6.6/os/x86_64/Packages/device-mapper-1.02.90-2.el6.x86_64.rpm http://vault.centos.org/6.6/os/x86_64/Packages/device-mapper-event-1.02.90-2.el6.x86_64.rpm http://vault.centos.org/6.6/os/x86_64/Packages/device-mapper-event-libs-1.02.90-2.el6.x86_64.rpm https://dl.fedoraproject.org/pub/epel/testing/6/x86_64/docker-io-1.6.2-1.el6.x86_64.rpm

示例： 
启动容器 ：docker run -d ubuntu /bin/sh -c “while true; do echo hello world; sleep 2; done” 
容器里执行：docker exec ubuntu /bin/sh -c “ls /;”

更简单的升级内核方法，经测试成功！
这里通过yum快速升级CentOS 6.x内核到3.10：
# rpm -ivh http://www.elrepo.org/elrepo-release-6-5.el6.elrepo.noarch.rpm
# yum --enablerepo=elrepo-kernel install kernel-lt -y
在grub.conf中确认装好的内核在哪个位置：
# vi /etc/grub.conf
default=0
重启系统，后查看内核信息：
# uname -r
3.10.65-1.el6.elrepo.x86_64

检查docker依赖环境的脚本check-config.sh

#!/usr/bin/env bash
