Once I have a complex thing to recompile the kernel, many people will have such fear. However, after reading this article, I hope you will feel relaxed, the original kernel is so simple.
First, the reason for upgrading the kernel
There are many reasons for the upgrade, such as new hardware drivers, remove kernel BUG, usually the new core will be faster, more stable and reliable than older versions.
Second, download the source code and extract
Freeelamp.com Home The latest download connection of LAMP versions of Lamp.com is available. You can directly click to download.
After download, we compressed files to / usr / src:
Gzip -dc Linux-2.4.19.tar.gz | TAR XVVF -
MV Linux-2.4.19 / usr / src
CD / USR / SRC
If there is a Linux directory exist, remove it first, then create a Linux soft connection:
RM-RF Linux
ln -s Linux-2.4.19 Linux
What is the matter of downloading a patch:
Gzip -d path-2.4.19.gz
MV PATCH-2.4.19 / USR / SRC
Determine hardware:
Before upgrading the kernel, you need to know the hardware on your machine to install the appropriate module. To view the hardware commands:
LSPCI lists all PCI devices.
Dmesg can also give a lot of useful information.
Third, compile the source code
CD / USR / SRC / Linux
Make Mrproper
Next, you can choose one of the following commands to configure the kernel:
'make config' - Suitable for slow remote terminal connectivity
'make menuconfig' - a remote terminal or this machine suitable for high speed
'make Xconfig' - on the X11 window
'make oldconfig' - use the previous .config file (useful when upgrading)
Then, according to the menu, select the appropriate configuration, delete the configuration that you don't need, the kernel, the faster the system is running. After the configuration is complete, the deployment exits. enter:
Make Dep; Make Bzimage; Make Modules
Make modules_install
Copy the boot file,
CP / USR / SRC / Linux / Arch / I386 / Boot / Bzimage /Boot/kernel-2.4.19
/ boot The following file name can be taken at will, but kernel-2.4.19 is relatively simple, easy to memorize.
Fourth, configure LILO
CD / ETC
Modify lilo.conf, add:
Image = / boot / kernel-2.4.19
Label = linux-2.4.19
Read-only
Root = / dev / hda1
Running LILO
Restart the machine, if you can run it properly, congratulations, success.
If there is a problem, modify the default to the old kernel version, and re-run the LILO.
Then, recompile the kernel:
CD / USR / SRC
Make clean
Reconfigure, check the possible problems.
Install patch
Simply installing patch is very simple, just step:
CD / USR / SRC
PATCH -P0
