Compile the Linux kernel 2.6.25.10 by yourself

Compile the Linux kernel 2.6.25.10-general Linux technology-Linux programming and kernel information by yourself. For more information, see the following. First introduce the environment: Fc7, the original kernel version 2.5.23

1.download the internal source code package linux-2.6.25.10.tar.bz2 at www.kernel.org.

2.copy the internal source code package linux-2.6.25.10.tar.bz2 to the/usr/src directory.

3. Open the terminal and enter the following commands in sequence:

Cd/usr/src // enter the/usr/src directory

4. tar? Jxvf linux-2.6.25.10.tar.bz2 // extract the kernel source code compressed package, unzip the file for the linux-2.6.25.10

5. ln? S linux-2.6.25.10 linux // map a linux Symbolic connection to a linux-2.6.25.10

6. cd linux // enter the linux directory

7. make xconfig // use the graphical interface to configure the kernel and remove unnecessary features, such as Bluetooth and other wireless modules. The dot in front of each option indicates that the item will be directly compiled into the kernel, and the dot in front indicates that the item will be compiled into a module. Blank indicates that this item is not compiled.

8. make bzImage // generate the gzip-compressed kernel. The generated file is located in the usr/src/linux/arch/i386/boot directory.

9. make modules modules_install // compile the module and install it in/lib/modules/2.6.25.10.

10. cp arch/i386/boot/bzImage/boot/vmLinux2.6.25.10 // copy the kernel file to the startup directory

11. cp System. map/boot/System. map-2.6.25.10 // copy the kernel symbol table to the startup directory.

12. cd/boot // enter the startup directory

13./sbin/mkinitrd initrd-2.6.25.10.img 2.6.25.10 // generate a memory disk for initrd-2.6.25.10.img initialization.

14. Modify GRUB:

Go to the/boot/grub/directory and open the grub. conf file under the directory.

Add the following content to the file:

Title myLinux2.6.25.10
Root (hd0, 4)
Kernel/vmlinux2.6.25.10 root = LABEL =/1
Initrd/initrd-2.6.25.10.img

Restart the computer and select myLinux2.6.25.10 from the GRUB list to enter the new kernel.

Note: run the uname-a command to query the kernel version number of the current system.

Today, I just learned that the new kernel version is 2.6.26. compile it later.
