Tip:

64-bit operating system, kernel version is at least 3.10.

Pre-upgrade system image: CentOS 6.564-bit

Kernel version: 2.6.32-431.23.3.el6_x86_64

1. Import public key

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

2. Install elrepo into CentOS with kernel 2.6.32

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

3. Install the long-term supported version of kernel-lt (long term support)

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

4. Install docker

You need to install the yum source first.

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

Re-execution

Yum install docker-io

Note:

1) if you use the elrepo source directly through yum, the speed will be slow (the source is abroad).

It is recommended to install kernel-lt with rpm:

Visit http://elrepo.org/linux/kernel/el6/x86_64/RPMS/ to download the corresponding rpm package, and install it through rpm:

Rpm-ivh kernel-lt-3.10.93-1.el6.elrepo.x86_64.rpm

2) you will be prompted to upgrade the kernel in Centos 6.5. in addition, there is an error.

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

Perform yum upgrade device-mapper-libs to upgrade

4. Edit the grub.conf file and modify the Grub boot sequence

Vim / etc/grub.conf

Confirm the location of the installed new kernel, and adjust the value of default to the order of the new kernel. For example, in this upgrade case, the newly installed kernel location is 0, so change default to 0, save and exit, and reboot restart the server.

5. Check the kernel after restarting the system

6. Test after the kernel upgrade is completed

After the upgrade is completed, you can install docker to observe the use:

Yum install-y docker-io

Service docker start

Docker pull centos:6

Docker run-it centos:6 / bin/bash
