How to Upgrade Linux Kernel

You can also go to your local/boot directory to find configuration files suitable for your local machine.

# Make menuconfig configure the kernel

Step 4 compile the kernel

# Make

Step 5 compile the module

# Make modules

Part 6 installation Module

# Make modules_install

Step 7 install the kernel

# Make install

Step 8 configure the Startup File

Check whether the configuration file of grub or lilo is correctly modified. If it has been modified, you do not need to change it manually. Otherwise, you need to modify the configuration file so that the system can be booted through the new kernel at the next restart.
