Linux内核编译过程详解(kernel2.6.7)

　　三 编译

　　按如下命令编译,大概需要一个多小时,大可以好好放松一下make bzImage
make modules
make modules_install
make install

　　运行新内核之前,请检查一下/boot/grub/grub.conf的内容,下面的配置可作参考# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# 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/hdc3
# initrd /initrd-version.img
#boot=/dev/hdc
default=1
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.6.7)
root (hd0,0)
kernel /vmlinuz-2.6.7 ro root=LABEL=/
initrd /initrd-2.6.7.img
title Red Hat Linux
root (hd0,0)
kernel /vmlinuz-2.4.20-8 ro root=LABEL=/
initrd /initrd-2.4.20-8.img

　　四 运行内核的常见问题

　　1)RPM问题

　　进入编译好的内核后，与RPM相关的命令有些不能使用，并出现下列错误：rpmdb: unable to join the environment
error: db4 error(11) from dbenv->open: Resource temporarily unavailable
error: cannot open Packages index using db3 - Resource temporarily unavailable (11)
error: cannot open Packages database in /var/lib/rpm
no packages

　　解决方法是执行“export LD_ASSUME_KERNEL =2.2.25”命令，也可以将其写入/etc/bashrc。
