centos5.5 內核升級記錄

1下載#wget  http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.35.9.tar.bz2

2解壓#tar -xjvf linux-2.6.35.9.tar.bz2

3放到內核源代碼目錄#mv linux-2.6.35.9  /usr/src/kernels

4編譯準備

沒有安裝gcc不能make編譯，因此首先還得#yum install gcc

#cd linux-2.6.30
#make mrproper   清除環境變量，即清除配置文件

#make menuconfig 在菜單模式下選擇須要編譯的內核模塊:

編譯提示先裝ncurses-devel

#yum install ncurses-devel

安裝成功後再#make menuconfig 出現配置畫面：

 配置這個真頭大，看配置手冊配置項也太多了，不少設備都不知道什麼用，看文檔和配置手冊配了幾樣（配置本身配，我也搞不清楚），保存退出。

配置參考。http://www.chinaunix.net/jh/4/16106.html

保存就是保存.config.沒有.config是不能編譯的。若是有幾個方案，保存多.config1,能夠load.

修改.config文件

在.config文件搜索CONFIG_SYSFS_DEPRECATED_V2，會發現# CONFIG_SYSFS_DEPRECATED_V2 is not set這一行，將該行修改成CONFIG_SYSFS_DEPRECATED_V2=y

否則報錯Volume group not found

5配置完了，開始編譯

#make clean   確保全部東西均保持最新狀態.
#make bzImage   生成內核文件

編譯很久很久。出門吃飯逛了一圈回家編譯完了

Root device is (253, 0)
Setup is 12664 bytes (padded to 12800 bytes).
System is 2399 kB
CRC 2d5d3d3f
Kernel: arch/x86/boot/bzImage is ready  (#1)

#make modules 編譯模塊

又是一個難熬的過程。

#make modules_install 安裝模塊

#make install   安裝

這兩安裝很快

#mkinitrd   /boot/initrd_2.6.35.9.img   2.6.35.9根據內核版本和指定參數生成映像文件

彷佛OK了。

而後配置grub啓動。

#vi /etc/grub.conf

# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
#          initrd /initrd-version.img
#boot=/dev/sda
default=0  #此處1改成0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.35.9)
        root (hd0,0)
        kernel /vmlinuz-2.6.35.9 ro root=/dev/VolGroup00/LogVol00
        initrd /initrd-2.6.35.9.img
title CentOS (2.6.18-194.el5xen)
        root (hd0,0)
        kernel /xen.gz-2.6.18-194.el5
        module /vmlinuz-2.6.18-194.el5xen ro root=/dev/VolGroup00/LogVol00
        module /initrd-2.6.18-194.el5xen.img
title CentOS-base (2.6.18-194.el5)
        root (hd0,0)
        kernel /vmlinuz-2.6.18-194.el5 ro root=/dev/VolGroup00/LogVol00
        initrd /initrd-2.6.18-194.el5.img

OK。重啓。
