一个Linux爱好者的2.6.11内核编译过程(2)

[ ] ISA support

[*] EISA support

[*] Vesa Local Bus priming

[*] Generic PCI/EISA bridge

[*] EISA virtual root device

[ ] EISA device name database

[ ] MCA support

< > NatSemi SCx200 support

PCCARD (PCMCIA/CardBus) support --->

PCI Hotplug Support --->

PCCARD (PCMCIA/CardBus) support --->一般只有笔记本电脑上才会有PCMCIA插槽，如果你是台式机的话，可以不选这一项，然后跳过这一部份。

PCI Hotplug Support --->

< > Support for PCI Hotplug (EXPERIMENTAL)

一般来讲只有服务器上会有热插拔的设备，如果你使用的是台式机，你可以不选择此项并跳过这一部份。

可执行文件格式，

[*] Kernel support for ELF binaries

ELF是开放平台下最常用的二进制文件，它支持不同的硬件平台

< > Kernel support for a.out and ECOFF binaries

<*> Kernel support for MISC binaries

此选项允许插入二进制的封装层到内核中，当使用Java、.NET、Python、Lisp等语言编写的程序时非常有用

硬件设备相当复杂，看得偶头晕，大家针对自己的设备慎重选择（手边最好准备一本汉英字典：）如果想使用adsl，记得网络部分除了TCP/IP协议还得把ppp部分编译进内核，想当初偶就是把这个给忘了，郁闷了许久。

文件系统，

<*> Second extended fs support

[*] Ext2 extended attributes

[*] Ext2 POSIX Access Control Lists

[*] Ext2 Security Labels

<*> Ext3 journalling file system support

[*] Ext3 extended attributes

[*] Ext3 POSIX Access Control Lists

[*] Ext3 Security Labels

[ ] JBD (ext3) debugging support

<*> Reiserfs support

[ ] Enable reiserfs debug mode

[ ] Stats in /proc/fs/reiserfs

[*] ReiserFS extended attributes

[*] ReiserFS POSIX Access Control Lists

[*] ReiserFS Security Labels

JFS filesystem support

[*] JFS POSIX Access Control Lists

[ ] JFS debugging

[ ] JFS statistics

XFS filesystem support

[*] Realtime support (EXPERIMENTAL)

[*] Quota support

[*] Security Label support

[*] POSIX ACL support

< > Minix fs support

< > ROM file system support

[*] Quota support

< > Old quota format support

Quota format v2 support

[*] Dnotify support

< > Kernel automounter support

< > Kernel automounter version 4 support (also supports v3)

CD-ROM/DVD Filesystems --->

DOS/FAT/NT Filesystems --->

Pseudo filesystems --->

Miscellaneous filesystems --->

Network File Systems --->

Partition Types --->

Native Language Support --->

Profiling support --->

Kernel hacking --->

Security options --->

Cryptographic options --->

Library routines --->

这个东东你要是搞不来就不要搞，默认的也可以的。先学习一下怎么样编译内核，等成功了，有了经验了在改也没有事的！

编译内核:

# cd /usr/src/linux

# make dep -----链接程序代码与函数库.

# make clean -----删除不必要的模块和文件.

# make bzImage -----开始编译系统内核.

# make modules -----开始编译外挂模块.

# make modules_install -----安装编译完成的模块.

要好常时间的，我洗了一件衣服，抽了N根白沙之后，总算完成了，好激动呀！

# su -

# /sbin/depmod -a -----创建模块的链接.

更换内核:

# cd /boot -----切换到引导分区/boot.

# rm System.map vmlinuz -----删除旧的符号链接.

# mv /usr/src/linux/System.map System.map

# mv /usr/src/linux/arch/i386/boot/bzImage vmlinuz

如果你用GRUB来管理开机,简单点就是你装了win还装了linux就要修改/boot/grub下的menu.1st文件:

# vi /boot/grub/menu.1st

键入i进入编辑模式:

# grub.conf generated by anaconda

#

# Note that you do not have to rerun grub after making changes to this file

# NOTICE: You do not have a /boot partition. This means that

# all kernel and initrd paths are relative to /, eg.

# root (hd0,1)

# kernel /boot/vmlinuz-version ro root=/dev/hda2

# initrd /boot/initrd-version.img

#boot=/dev/hda

default=1

timeout=10

splashimage=(hd0,1)/boot/grub/splash.xpm.gz

title Fedora Core(2.6.11)

root (hd0,1)

kernel /boot/vmlinuz ro root=/dev/hda2 ---你的linux所在的分区

title DOS

rootnoverify (hd0,0)

chainloader +1

title Fedora Core(2.4.22)

root (hd0,1)

kernel /boot/vmlinuz-2.4.22-1.2115.nptl ro root=LABEL=/ hdd=ide-scsi rhgb

initrd /boot/initrd-2.4.22-1.2115.nptl.img

这样还可以保留旧版本的内核以防编译新内核失败进不了系统

重启电脑，好了，进去了。网上说新内核速度好快的，我怎么感觉快不了多少呢。无所谓了，反正是成功了。呵呵，我可是失败了很多次才成功的。好高兴，2点了，穿衣服去吃东西了。

rpm没法用了，怎么办？

在/usr/lib/rpm/macros里面寻找代码:

%__dbi_cdb create cdb mpool mp_mmapsize=16Mb mp_size=1Mb

修改成代码:

%__dbi_cdb create cdb mpool mp_mmapsize=16Mb mp_size=1Mb private
