This article mainly introduces "how to upgrade centos Docker to kernel 3.10 before installation". In daily operation, I believe many people have doubts about how to upgrade centos Docker to kernel 3.10 before installation. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "how to upgrade centos Docker to kernel 3.10 before installation". Next, please follow the editor to study!

First of all, my virtual machine system is Centos 6.5.

1. The problem occurs in ESXI 6.0. Install kernel-3.10.5 first, then install devel

2. ESXI 5.5 does not have this problem. Install devel first, then install kernel-3.10.5

later

3. The problem does not occur in ESXI 6.0. Install devel first, then install kernel-3.10.5

All I operate is a virtual machine, but I don't know how to do it on a real machine.

Everyone must remember the installation steps, or else it will be a pit. Trust me, the lesson of blood. I'll show you what happened to me! There is no initrd.img add-on, it is useless for me to add it manually! This is when I reboot the 2.6.32 kernel to view this file. In fact, when I boot, I can see only two items.

Rpm-ivh kernel-ml-aufs-devel-3.10.5-3.el6.x86_64.rpm

Rpm-ivh kernel-ml-aufs-3.10.5-3.el6.x86_64.rpm

Download the kernel package and install it

The code is as follows:

Check your own kernel

Uname-r

2.6.32-431.el6.x86_64

Due to my incompetence, I can't compile the kernel, so I can only find a place to download it. The download address is attached:

Https://www.yisu.com/softs/499066.html

Kernel-ml-aufs-3.10.5-3.el6.x86_64.rpm

Kernel-ml-aufs-devel-3.10.5-3.el6.x86_64.rpm

Decompression

Gunzip kernel-ml-aufs-3.10.5-3.el6.x86_64.rpm.gz

Gunzip kernel-ml-aufs-devel-3.10.5-3.el6.x86_64.rpm.gz

Install the RPM package

Rpm-ivh kernel-ml-aufs-3.10.5-3.el6.x86_64.rpm.gz kernel-ml-aufs-devel-3.10.5-3.el6.x86_64.rpm.gz

After the installation, modify / etc/grub.conf and restart

The code is as follows:

Vim / etc/grub.conf

Change default=1 to default=0

Indicates that the content under the first title is the kernel started by default (usually the newly installed kernel is in the first location).

As you can see in the following figure, the kernel has been upgraded to 3.10.5

Restart the system after modification, because the system is not recognized yet. You can try uname-r.

OK, at this time, the system has been rebooted. Let's take a look at the kernel. It becomes 3.10.5.

Download the epel source and install docker

The code is as follows:

The latter part is relatively simple, so I won't go into details. If you install docker, you can refer to the article at the end of my article.

Wget http://mirrors.yun-idc.com/epel/6/x86_64/epel-release-6-8.noarch.rpm

Rpm-ivh epel-release-6-8.noarch.rpm

Yum clean all

Yum-y install docker-io

Service docker start

Docker-d

At this point, the study on "how to upgrade centos Docker to kernel 3.10 before installation" is over. I hope to be able to solve your doubts.
