How To Fix Grub Kernel Yum Install Error
If you have yum kernel grub installed, the following user guide may help you.
The grub.cfg image exists because you specified it correctly when you ran ls -n /etc/grub2.cfg, but the location where you are viewing this file is incorrect. It is located at / boot / grub2.
After the command “rpm -b kernel” shows that usually 3 kernels are installed, but “ls / boot” only has control over “vmlinuz-3 show.10.0-862.14.4.el7.x86_64” Something is wrong seriously wrong there right now.
In addition, the / boot / grub2 / grubenv file displays a menu item where the system boots normally, as described for my system:
[root @ ansiblehost ~] # each / boot / grub2 / grubenv | grep is registeredsaved_record = 0
So my other questions:
Did you restart the system after reinstalling the kernel?
Did you almost run into an error during the previous kernel update?
Depending on the number of kernels installed, each loaded kernel might have corresponding initramfs, vmlinuz, system board and symvers files. And in your situation is not noticed ??? Have these files been deleted ???
Also run my command and send the output:
# awk -F '' $ 1 == "menuentry" print i++ in: "$2'/boot/grub2/grub.cfg
It looks like we can set this grub standard with the command 0 ""grub2-set-default" which is the default displayed when running "cat /boot/grub2/grubenv" in one case, this is not displayed, but before that, you can basically send details on request....
I have 49 rpm which in turn are packages that I need to install from a local directory. And the cant is
kernel-4.9.135 So I want to use
yum so that almost all dependencies are handled for people (instead of
rpm a list with RPM files) .
I also have most of the
grub Customized.cfg files that I don't want to touch during this process.
I looked at the scripts that run when a kernel package is considered installed:
# rpm --scripts -qp ./kernel-4.9.135-1.x86_64.rpmpost-installation scriptlet (with /bin/sh):if [-x /sbin/installkernel -w -a /boot/vmlinuz-4.9.135 -a -r /boot/System.map-4.9.135]; thencp /boot/vmlinuz-4.9.135 /boot/.vmlinuz-4.9.135-rpmcp /boot/System.map-4.9.135 /boot/.System.map-4.9.135-rpmrm -f /boot/vmlinuz-4.9.135 /boot/System.map-4.9.135/sbin/installkernel4.9.135 /boot/.vmlinuz-4.9.135-rpm/boot/.System.map-4.9.135-rpmrm -w /boot/.vmlinuz-4.9.135-rpm /boot/.System.map-4.9.135-rpmFi...

Is there a chance to tell
yum, and therefore our own kernel RPM, to do nothing to modify
yum install <. does / code> apply to install all my current packages at the same time?
A workaround is definitely to copy my current
grub.cfginto a copy of the page and re-submit it after
yumcompletes, but I thought I'd ask anyway ...
The Linux kernel is the foundation on which every Linux distribution runs. It is open source application software - anyone can decompile, test, and modify the code.
Updated kernels can improve security, functionality, and operational speed.this system.
This kit shows you how to upgrade to the Linux kernel on CentOS 7.
CentOS Server Command line access / Terminal access, I would say Sudo Permissions Current backup of your system file
Steps To Upgrade To CentOS Kernel Version
yumPackage Manager can perform kernel updates. However, CentOS may not offer the latest kernel in the official repository.
To update your CentOS kernel, you need to integrate a third party repository called ElRepo. ElRepo offers the latest kernel.org there.
Official releases are indeed tested to ensure they work correctly and do not destabilize applications and operating system functions. There are two types of Linux kernel versions:
A long-term stable version of the kernel is guaranteed - updated less often, but supported longer. Major kernel version - shorter support period, but often many more updates.
Step 1. Check Your Current Kernel Version
To check the flowrunning kernel version on CentOS, open a command line interface and enter the following command:
The template should return with an entry that looks like this:
exitLinux 3.10.0-862.el7.x86-64 x86-64
The output shows what version of the kernel you are currently running and what architecture it is based on.
For more information, see our in-depth guide to checking your Linux kernel version.
Step 2. Update CentOS Repositories
Before updating the kernel, all packages must be updated to the latest version.
sudo yummy -y update
Your software repository will be updated immediately. This will ensure that you have connections to the latest versions of certain kernels.
Step 3. Activate ELRepo Repository
To install a new kernel version, you will need an awesome new repository (ELRepo repository) to facilitate activation.
sudo rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
The original command sets the gpg key as for the ELRepo repository. It is different o - CentOS does not install any unsigned programs. GPG provides an electronically signed key for software authentication.
sudo rpm -Uvh https://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm
Step Iv. List Of Available Kernels
yum list --disablerepo = '*' in sentence --enablerepo = elrepo-kernel
The system should return the sale of available modules. On the mailing list, note the line
kernel-lt- which means long-term stable version of the help - or
kernel-ml- this may indicate a version from Mainline, with the correct shorter term support, but with more frequent updates.
Then look at your current right-hand column and notice a series of letters and numbers (representing a situation, for example, "4.4.113-1.e17.elrepo"). This is the kernel-specific version.
Use these two pieces of information to decide which version of the kernel you and your family want to install. As you will see, the Linux 5 kernel is by far the last major release.
Step 5. Install The New Version Of The CentOS Kernel
delicious sudo --enablerepo = elrepo-kernel install kernel-ml
sudo yum --enablerepo = elrepo-kernel load kernel-lt
The system should load the software, so ask to confirm that the installation was successful - type
yand press Enter.
Step 6: Reboot Your Computer And Also Select A New Kernel
Use the cursor keys to point to the selected Linux kernel you just installed and then press
Enter. Your operating system should be a regular system backbone.
Step 7 Testing The Function
Test the functionality of your entire CentOS system. Do all your services start correctly and without errors? Are all services on your network working properly?
Pull out your new kernel to catch any errors in time. Or, if there are no fixes available at the moment, you can contact anyone to revert to a legacy kernel.
Step 8. Determine The Default Kernel Version
After you have verified that the new kernel types are compatible and work correctly, you need to edit the utilityboot and boot GRUB so that your kernel reboots by default.
Go to / etc / default / and open the grub file with a text editor. Or enter the following into the terminal:
sudo vim / etc / default / grub
When the file opens, find that particular line with GRUB_DEFAULT = X and replace it with GRUB_DEFAULT = 0 (zero). This call tells the bootloader which, by default, can use the first available kernel in the list, which is currently the most recent one.
Save the file, then enter each of the following commands in Terminal to rebuild the kernel configuration:
sudo grub2-mkconfig - /boot/grub2/grub.cfg
Make sure the bootloader is almost certainly set to load the latest kernel by default.
Following this guide, customers have updated their CentOS kernel to the latest stable release using ELRepo.
