docker安装

docker安装不支持2.6 即 centos 6.5内核

升级内核   

导入public key

wget https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

rpm --import RPM-GPG-KEY-elrepo.org

rpm -Uvh http://www.elrepo.org/elrepo-release-6-8.el6.elrepo.noarch.rpm

安装**kernel-lt(lt=long-term)**

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

或者安装kernel-ml(ml=mainline)

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

4.>编辑grub.conf文件,修改Grub引导顺序

复制代码
vim /etc/grub.conf

# grub.conf generated by anaconda
#
default=0
timeout=5
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
hiddenmenu
title CentOS (3.10.28-1.el6.elrepo.x86_64)
        root (hd0,0)
        kernel /boot/vmlinuz-3.10.28-1.el6.elrepo.x86_64 ro root=UUID=0a05411f-16f2-4d69-beb0-2db4cefd3613 rd_NO_LUKS  KEYBOARDTYPE=pc KEYTABLE=us rd_NO_MD crashkernel=auto.UTF-8 rd_NO_LVM rd_NO_DM rhgb quiet
        initrd /boot/initramfs-3.10.28-1.el6.elrepo.x86_64.img
title CentOS (2.6.32-431.3.1.el6.x86_64)
        root (hd0,0)
        kernel /boot/vmlinuz-2.6.32-431.3.1.el6.x86_64 ro root=UUID=0a05411f-16f2-4d69-beb0-2db4cefd3613 rd_NO_LUKS  KEYBOARDTYPE=pc KEYTABLE=us rd_NO_MD crashkernel=auto.UTF-8 rd_NO_LVM rd_NO_DM rhgb quiet
        initrd /boot/initramfs-2.6.32-431.3.1.el6.x86_64.img
复制代码

确认刚安装好的内核在哪个位置,然后设置default值(从0开始),一般新安装的内核在第一个位置,所以设置default=0

5.>重启,查看内核版本号.

[root@localhost ~]# reboot
[root@localhost ~]# uname -r
3.10.104-1.el6.elrepo.x86_64

至此,CentOS6.5的内核升级完成,下面就可以安装docker了.

二.安装docker

 直接使用命令: yum install docker-io   是会报错的!!!  提示:No package docker-io available.

 需要先安装yum 源.

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

再执行

 sudo yum install device-mapper-event-libs

yum install docker-io

就可以正常安装了!!

在安装的过程中由于dns的问题报了错,所以要设置好自己的dns确保服务器能连接到外网,我当时设置的dns为:

vim /etc/resolv.conf 
nameserver 8.8.8.8
nameserver 8.8.4.4

启动docker

service docker start

查看docker版本:

复制代码
[root@localhost ]# 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
复制代码

查看docker日志.

cat /var/log/docker

 至此,docker安装完成!!!

三、卸载docker

列出你安装过的包

[root@localhost ~]# yum list installed | grep docker
docker-io.x86_64                     1.7.1-2.el6                        @epel  

删除软件包

yum -y remove docker-io.x86_64
删除镜像/容器等
rm -rf /var/lib/docker

四、升级docker版本为1.10.3

升级之前停止docker服务,并将原有的docker服务进行备份. mv /usr/bin/docker /usr/bin/docker.bak

nohup wget -c https://get.docker.com/builds/Linux/x86_64/docker-1.10.3 -O /usr/bin/docker 

给执行权限:chmod 755 /usr/bin/docker 然后重启服务,并查看版本.
