  • CentOS6安装docker

    1、升级内核到3.10

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

    2、修改grub的主配置文件/etc/grub.conf,设置default=0,表示第一个title下的内容为默认启动的kernel(一般新安装的内核在第一个位置),修改之后如下:

    [root@localhost ~]# cat /etc/grub.conf
    # 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
    title CentOS (3.10.5-3.el6.x86_64)
    	root (hd0,0)
    	kernel /vmlinuz-3.10.5-3.el6.x86_64 ro root=UUID=78514585-1521-472c-8ca4-110fb82e9959 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
    title CentOS (2.6.32-431.el6.x86_64)
    	root (hd0,0)
    	kernel /vmlinuz-2.6.32-431.el6.x86_64 ro root=UUID=78514585-1521-472c-8ca4-110fb82e9959 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-2.6.32-431.el6.x86_64.img
    

    3、重启系统,这时候你的内核就成功升级了,执行uname -r

    [root@localhost ~]# uname -r
    3.10.5-3.el6.x86_64
    

    4、确保系统中yum下载的包是最新的

    sudo yum update
    

    5、创建docker的yum源

    sudo tee /etc/yum.repos.d/docker.repo <<-'EOF'
    [dockerrepo]
    name=Docker Repository
    baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/
    enabled=1
    gpgcheck=1
    gpgkey=https://yum.dockerproject.org/gpg
    EOF
    

     6、安装docker

    sudo yum install docker-engine
    

     7、启动docker

    sudo service docker start
    

     8、查看docker服务状态

    service docker status

    如果显示 docker dead but pid file exists,则执行如下指令

    sudo yum-config-manager --enable public_ol6_latest
    sudo yum install device-mapper-event-libs
    

     9、再查看docker的服务状态

    [root@localhost ~]# service docker status
    docker (pid  2581) is running...
