Linux kernel compilation

Kernel commands

Modinfo + module Name: View module information

Lsmod: View modules running in the current kernel

Insmod + module Path: Load module

Modprobe + module Name: Loading module

MODPROBE-R Module Name: Unload module

RMMOD Module Name: Unload module

modifying kernel parameters

1 echo VALUE >/proc/sys/kernel/hostname

2 sysctl-w kernel.hostname= "VALUE"

Both of the above are effective immediately and cannot be permanently valid

3 vi/etc/sysctl.conf

Modify the configuration file to be permanent, but not effective immediately

You can execute the following command to make it effective immediately

Sysctl-p, this configuration file will be re-read to make it effective

To compile the kernel method:

Download a similar version of the kernel, unzip,

Copy/boot/config file to the extracted directory, for. config

Perform:

Make Menuconfig

Make

Make Modules_install

Make install

Compiling the kernel is a relatively hard work, time is longer, half an hour to five hours,

All try not to use remote compilation,

If you are not using remote compilation, you can use the screen command

Yum-y Install screen

Screen-ls (display screen)

Ctrl+a,d (Demolition screen)

Screen (new)

Screen-r ID (Restore screen)
