Docker (Linux kernel upgrade)

Docker is now generally deployed in systems above linux7. It requires that the Linux system kernel be in version 3.8 or higher. View Version command: uname-a

When the general Linux system is below 7, its kernel version is 2 points.

Uname-r2.6.32-358.11.1.el6.x86_64

Kernel Upgrade:

1. Import Public key

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

1.2 Download the source package

Go to http://www.kernel.org Home, download the source package

wget unzip the tar XF Linux-3.11.6.tar.xz

#查看已经安装的和未安装的软件包组 to determine if we have installed the appropriate development environment and development library;Yum grouplist#一般是安装这两个软件包组, this will make sure you have all the tools you need to compile
Yum Groupinstall "Development Tools"
#你必须这样才能让 make *config this command to execute correctly
Yum Install Ncurses-devel
#如果你没有 X Environment, this one can be used without
Yum Install Qt-devel
They are required #创建 CentOS-6 cores
Yum Install hmaccalc zlib-devel binutils-devel elfutils-libelf-devel

1.3 Update the current system (this step can first try not to do, directly below the 2)

sudo yum update

2. Start upgrading the kernel:

cd linux-3.11.6  #复制原内核配置   cp /boot/config-2.6.32-358.el6.x86_64 .config   vim .config  Add the following   chase to .config  and save (append to file last)     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 # Edit kernel configuration, open kernel Cgroup support   make menuconfig  #选择General  setup-->Control Group  Support->memory resource controller for control groups selected (select Save. OK)  # automatically organize. config

#重启 reboot

In view:

# Uname-r

3.11.6

(The kernel has risen from 2 to 3 points to 11.) You can install Docker. LINUX6 series)
