Recompile and install the Ubuntu Kernel

Recently, the abiCloud cloud computing environment has been set up, so you need to install vbox on the node (of course, vmware can be used ). Because vbox needs to be compiled into the kernel, the Ubuntu kernel is re-compiled. The following is the entire compilation process: first, check the kernel version and run the following command: (my node uses Ubuntu9.10 desktop version) root @ hker-laptop: /## uname-a: Linuxhker-la

Recently, the abiCloud cloud computing environment has been set up, so you need to install vbox on the node (of course, vmware can be used ). Because vbox needs to be compiled into the kernel, the Ubuntu kernel is re-compiled.

The entire compilation process is as follows:

First, check the kernel version and run the following command: (my node uses Ubuntu 9.10 desktop version)

Root @ hker-laptop: // # uname-
Returned information:
Linux hker-laptop 2.6.31-14-generic # 48-Ubuntu SMP Fri Oct 16 14:04:26 UTC 2009 i686 GNU/Linux
Download your website from the kernel Website: http://www.kernel.org. Here I downloaded the 2.6.31-8 version, which is lower than my own version, but it does not matter. It is important to complete the task. Use this version for installation!
First, extract linux-2.6.31.8.tar.gz to the/usr/src/directory.
Root @ hker-laptop:/usr/src/# cd/usr/src/
Root @ hker-laptop:/usr/src/linux/# tar zxvf linux-2.6.31.8.tar.gz
Root @ hker-laptop:/usr/src/linux/# mv linux-2.6.31.8 linux (New linux directory, and establish this directory with excellent connection, it seems no difference :))

Root @ hker-laptop:/usr/src/linux/# make oldconfig
Root @ hker-laptop:/usr/src/linux/# make prepare
Root @ hker-laptop:/usr/src/linux/# make modules_prepare
Root @ hker-laptop:/usr/src/linux/# cd ..
Root @ hker-laptop:/usr/src/# make-C linux M =/usr/src/linux/net/mac80211/modules
Root @ hker-laptop:/usr/src # cp linux/net/mac80211/modules. order linux/
Root @ hker-laptop:/usr/src # cd linux
Root @ hker-laptop:/usr/src/linux # make modules_install
Root @ hker-laptop:/usr/src # cd linux
Root @ hker-laptop:/usr/src/linux # make all :()
OK is finally compiled!
Root @ hker-laptop:/usr/src/linux # make install
This step copies the compiled vmlinux-2.6.31.8 to the/boot directory and creates a System. map-2.6.31.8 ing. But here there is a missing initrd. img-2.6.31.8! Set this by yourself!
You can use the mkinitramfs command to generate the initrd. img-2.6.31.8 file.
Root @ hker-laptop:/usr/src/linux/# cd/lib/modules
Root @ hker-laptop:/lib/modules/# mkinitramfs-o/boot/initrd. img-2.6.31.8
OK. Generation successful!
