2.Copy code to work directory: #cp linux-2.6.18.1.tar.gz /usr/src #cd /usr/src 3.If there is an old edition,delete the symbol link: #rm -f linux-2.4 4.decompress the packdge: #tar -zxvf linux-2.6.18.1.tar.gz 5.enter the compile directory: #cd /usr/src/linux-2.6.18.1 6.This command ensure there is no .o file & dependence between files in the directory #make mrproper 7make a backup #cp -r /boot /boot_bak 8.see the position of root directory #df 以下是偶机器的部分输出: Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 22G 3.7G 17G 19% / /dev/hda3 99M 12M 82M 13% /boot ... 看看你的系统根目录装在哪里很重要,因为后面你将会看到系统安装编译好的内核时在grub.conf插入的命令中root=LABEL=/ hdc=ide-scsi 可能会引发系统引导时的如下错误: VFS: Cannot open root device "" or 00:00 Please append a correct "root=" boot option Kernel panic: VFS: Unable to Mount root fs on 00:00 所以要在grub.conf里可能会修改其命令为:root=/dev/VolGroup00/LogVol00 9.#cd /usr/src/linux-2.6.18.1 #make menuconfig 8.3用以下命令读取刚才的配置数据使之生效: #make dep #make clean 9.开始编译内核和模块 #make bzImage #make modules #make modules_install 10.将编译好的文件移到/boot下; #mv /usr/src/linux-2.6.18.1/System.map /boot/System.map-2.6.18.1 #mv /usr/src/linux-2.6.18.1/arch/i386/boot/bzImage /boot/vmlinuz-2.6.18.1 #mkinitrd initrd-2.6.18.1.img 2.6.18.1 //上面的命令是用来创新initrd映像的,不创建这个文件,有时是启动不起来的,比如提示VFS错误等;
