构建基本的嵌入式Linux根文件系统

其实在去年8月份我做系统移植时就构建好了一个可以用的根文件系统，但是那时是跟着别人的《Linux全线移植文档》做的。有些东西我也不清楚，只是跟着做，做出来能用就了事了，没有深究其中的规范，以及文件系统中哪些要，哪些不要。

趁着今年过年的几天假期，我移植重新移植了U-Boot1.3.1和Linux2.6.24到S3C2410及S3C2440后，我想好好的看看有关文件系统构建方法和规范，整理整理构建根文件系统的文档。之后，我用了近一周的时间，慢慢研究《构建嵌入式Linux系统》这本书有关根文件系统的部分，以及一些网上的参考资料，不断地实验。构建好了一个精简的根文件系统，下面我只介绍构建的过程和方法，至于原理我给出以下参考资料，自己看吧。

1、《Linux系统移植》：一个经典的Linux移植文档，共有95页的PDF文档，内容十分详细，里面有根文件系统的创建，还多地方都有下载（有的网站称之为《Linux系统全线移植文档》等等），很值得参考。在这里感谢文档的作者们。

2、《构建嵌入式Linux系统》必看！里面对文件系统的构建讲的挺细。

3、《Filesystem Hierarchy Standard》 Linux文件系统的标准规范。我只看到英文的。

其他再遇到不懂的就google，基本上都是Linux的相关知识，都是找得到的。

（1）创建根文件系统的基本目录结构。
我把这个过程做成了shell脚本(文件名为mkroot ) ，很方便！

# ! / bin/ sh echo "creatint rootfs dir......" mkdir rootfs cd rootfs echo "making dir : bin dev etc lib proc sbin sys usr" mkdir bin dev etc lib proc sbin sys usr # 必备的8个目录 mkdir usr/ bin usr/ lib usr/ sbin lib/ modules




# Don't use mknod ,unless you run this Script as root !

# mknod -m 600 dev/console c 5 1

# mknod -m 666 dev/null c 1 3

echo "making dir : mnt tmp var" mkdir mnt tmp var chmod 1777 tmp mkdir mnt/etc mnt/jffs2 mnt/yaffs mnt/data mnt/temp mkdir var/lib var/lock var/log var/run var/tmp chmod 1777 var/tmp

echo "making dir : home root boot" mkdir home root boot

echo "done"

在你想要建立根文件系统的地方，运行：

[ tekkamanninja@Tekkaman- Ninja nfs] $ . / mkroot creatint rootfs dir. . . . . . making dir : bin dev etc lib proc sbin sys usr making dir : mnt tmp var making dir : home root boot done [ tekkamanninja@Tekkaman- Ninja nfs] $ cd rootfs/ dev/ [ tekkamanninja@Tekkaman- Ninja dev] $ su 口令： [ root@Tekkaman- Ninja dev] # mknod - m 600 console c 5 1; mknod - m 666 null c 1 3; exit exit [ tekkamanninja@Tekkaman- Ninja dev] $

（2 ）配置、编译和安装Busybox-1.9.1

[ tekkamanninja@Tekkaman- Ninja source] $ tar - xjvf busybox- 1. 9. 1. tar. bz2

修改Makefile 文件：

[ tekkamanninja@Tekkaman- Ninja busybox- 1. 9. 1] $ pwd / home/ tekkamanninja/ working/ source/ busybox- 1. 9. 1 [ tekkamanninja@Tekkaman- Ninja busybox- 1. 9. 1] $ kwrite Makefile . . . . . . ( 第151- 154行) # SUBARCH : = $( shell uname - m | sed - e s/ i. 86/ i386/ - e s/ sun4u/ sparc64/ / # - e s/ arm. * / arm/ - e s/ sa110/ arm/ / # - e s/ s390x/ s390/ - e s/ parisc64/ parisc/ / # - e s/ ppc. * / powerpc/ - e s/ mips. * / mips/ ) . . . . . . ( 第174行附近) # ARCH ? = $( SUBARCH) # CROSS_COMPILE ? = ARCH = arm CROSS_COMPILE = / home/ tekkamanninja/ working/ gcc4. 1. 1/ gcc- 4. 1. 1- glibc- 2. 3. 2/ arm- 9tdmi- linux- gnu/ bin/ arm- 9tdmi- linux- gnu- [ tekkamanninja@Tekkaman- Ninja busybox- 1. 9. 1] $ make menuconfig

在原有的基础上修改如下：

Busybox Settings --->
Installation Options --->
[*] Don't use /usr

( /home/tekkamanninja/working/nfs/rootfs ) BusyBox installation prefix

Busybox Library Tuning --->

[*] Support for /etc/networks

[*] Additional editing keys

[*] vi-style line editing commands

(15) History size

[*] History saving

[*] Tab completion

[*] Username completion

[*] Fancy shell prompts

Linux Module Utilities --->

[N] Support version 2.2.x to 2.4.x Linux kernels

Shells --->

--- Ash Shell Options 下的选项全选

[ tekkamanninja@Tekkaman- Ninja busybox- 1. 9. 1] $ make . . . . . . LINK busybox_unstripped Trying libraries: crypt m Library crypt is needed Library m is needed Final link with: crypt m [ tekkamanninja@Tekkaman- Ninja busybox- 1. 9. 1] $ make install

我是动态编译所以查看一下需要的动态库

[ tekkamanninja@Tekkaman- Ninja busybox- 1. 9. 1] $ / home/ tekkamanninja/ working/ gcc4. 1. 1/ gcc- 4. 1. 1- glibc- 2. 3. 2/ arm- 9tdmi- linux- gnu/ bin/ arm- 9tdmi- linux- gnu- readelf - d busybox Dynamic section at offset 0xac014 contains 22 entries: Tag Type Name/ Value 0x00000001 ( NEEDED) Shared library: [ libcrypt. so. 1 ] 0x00000001 ( NEEDED) Shared library: [ libm. so. 6 ] 0x00000001 ( NEEDED) Shared library: [ libc. so. 6 ] 0x0000000c ( INIT) 0xc0f0 0x0000000d ( FINI) 0x97608 0x00000004 ( HASH) 0x80e8 0x00000005 ( STRTAB) 0xa3c0 0x00000006 ( SYMTAB) 0x8b30 0x0000000a ( STRSZ) 3371 ( bytes) 0x0000000b ( SYMENT) 16 ( bytes) 0x00000015 ( DEBUG) 0x0 0x00000003 ( PLTGOT) 0xbc0ec 0x00000002 ( PLTRELSZ) 2976 ( bytes) 0x00000014 ( PLTREL) REL 0x00000017 ( JMPREL) 0xb550 0x00000011 ( REL) 0xb4e0 0x00000012 ( RELSZ) 112 ( bytes) 0x00000013 ( RELENT) 8 ( bytes) 0x6ffffffe ( VERNEED) 0xb400 0x6fffffff ( VERNEEDNUM) 3 0x6ffffff0 ( VERSYM) 0xb0ec 0x00000000 ( NULL ) 0x0

（3 ）修改和创建必要的文件。

[ tekkamanninja@Tekkaman- Ninja busybox- 1. 9. 1] $ cp - a examples/ bootfloppy/ etc/* /home/tekkamanninja/working/nfs/rootfs/etc/

[ tekkamanninja@Tekkaman- Ninja busybox- 1. 9. 1] $ cd ../../nfs/rootfs/etc /

1 、增加为SHELL 导入全局变量的文件/etc/profile

[tekkamanninja@Tekkaman-Ninja etc]$ kwrite profile

# / etc/ profile: system - wide . profile file for the Bourne shells echo

echo "Processing /etc/profile... " # no- op

# Set search library path echo "Set search library path in /etc/profile" export LD_LIBRARY_PATH= / lib: / usr/ lib # Set user path echo "Set user path in /etc/profile" PATH= / bin: / sbin: / usr/ bin: / usr/ sbin export PATH # Set PS1 # 注意：ash 除了SHELL变量外，支持/u、/h、/W、/$、/! 、/n、/w 、/nnn（ASCII字符对应的八进制数） # 以及/e[ xx; xxm ( 彩色特效) 等等！ # 而且前面还要多加一个 '/' ！

echo "Set PS1 in /etc/profile"

export PS1="//e[05;32m[$USER@//w//a]//$//e[00;34m"

echo "Done"

echo

2 、增加初始化文件

[tekkamanninja@Tekkaman-Ninja etc]$ kwrite inittab

: : sysinit: / etc/ init. d/ rcS : : respawn: - / bin/ login : : restart: / sbin/ init : : ctrlaltdel: / sbin/ reboot : : shutdown : / bin/ umount - a - r : : shutdown : / sbin/ swapoff - a

[tekkamanninja@Tekkaman-Ninja etc]$ kwrite fstab

proc / proc proc defaults 0 0 none / tmp ramfs defaults 0 0 mdev / dev ramfs defaults 0 0 sysfs / sys sysfs defaults 0 0

3 、增加初始化脚本

[tekkamanninja@Tekkaman-Ninja etc]$ kwrite init.d/rcS

# ! / bin/ sh echo "----------mount all" / bin/ mount - a

echo "----------Starting mdev......" / bin/ echo / sbin/ mdev > / proc/ sys/ kernel/ hotplug mdev - s

echo "*********************************************************" echo " Tekkaman Ninja 2440 Rootfs(nfs) 2008.2 " echo " Love Linux ! ! @@ Love Ke Ke ! ! " echo "********************************************************"

4 、删除备份文件

[tekkamanninja@Tekkaman-Ninja etc]$ rm *~ init.d/*~

5、为mdev 创建配置文件

[tekkamanninja@Tekkaman-Ninja etc]$ vi mdev.conf

创建一个mdev.conf 文件，内容可有可无。

（4 ）为使用用户登录功能移植 TinyLogin

1、下载

从 http://tinylogin.busybox.net/ 下载 tinylogin-snapshot.tar.bz2 ，并解压 .

[tekkamanninja@Tekkaman-Ninja source]$ tar -xjvf tinylogin-snapshot.tar.bz2

2、修改tinyLogin的Makefile

[tekkamanninja@Tekkaman-Ninja source]$ cd tinylogin

[tekkamanninja@Tekkaman-Ninja tinylogin]$ kwrite Makefile

指明 tinyLogin 使用自己的算法来处理用户密码

USE_SYSTEM_PWD_GRP = false . . . . . . CROSS = / home/ tekkamanninja/ working/ gcc4. 1. 1/ gcc- 4. 1. 1- glibc- 2. 3. 2/ arm- 9tdmi- linux- gnu/ bin/ arm- 9tdmi- linux- gnu- CC = $( CROSS) gcc AR = $( CROSS) ar STRIPTOOL = $( CROSS) strip

3、编译并安装

[ tekkamanninja@Tekkaman- Ninja tinylogin] $ make PREFIX= / home/ tekkamanninja/ working/ nfs/ rootfs install Aborting install - - You must be root, otherwise I can 't.

make tinylogin be setuid root, which will cause it to fail.

make: *** [install] 错误 1

[ tekkamanninja@Tekkaman- Ninja tinylogin] $ su

口令：

[root@Tekkaman-Ninja tinylogin]# make PREFIX=/home/tekkamanninja/working/nfs/rootfs install

[root@Tekkaman-Ninja tinylogin]# exit

exit

我是动态编译所以查看一下需要的动态库

[ tekkamanninja@Tekkaman- Ninja tinylogin] $ / home/ tekkamanninja/ working/ gcc4. 1. 1/ gcc- 4. 1. 1- glibc- 2. 3. 2/ arm- 9tdmi- linux- gnu/ bin/ arm- 9tdmi- linux- gnu- readelf - d tinylogin Dynamic section at offset 0x9670 contains 21 entries: Tag Type Name/ Value 0x00000001 ( NEEDED) Shared library: [ libcrypt. so. 1] 0x00000001 ( NEEDED) Shared library: [ libc. so. 6] 0x0000000c ( INIT) 0x9c40 0x0000000d ( FINI) 0x10160

0x00000004 ( HASH) 0x8128 0x00000005 ( STRTAB) 0x9070 0x00000006 ( SYMTAB) 0x85e0 0x0000000a ( STRSZ) 1430 ( bytes) 0x0000000b ( SYMENT) 16 ( bytes) 0x00000015 ( DEBUG) 0x0 0x00000003 ( PLTGOT) 0x19740 0x00000002 ( PLTRELSZ) 1064 ( bytes) 0x00000014 ( PLTREL) REL 0x00000017 ( JMPREL) 0x9818 0x00000011 ( REL) 0x97c8

0x00000012 ( RELSZ) 80 ( bytes)

0x00000013 ( RELENT) 8 ( bytes) 0x6ffffffe ( VERNEED) 0x9758 0x6fffffff ( VERNEEDNUM) 2 0x6ffffff0 ( VERSYM) 0x9606 0x00000000 ( NULL ) 0x0

创建创建帐号及密码文件:

[ tekkamanninja@Tekkaman- Ninja tinylogin] $ cd . . / . . / nfs/ rootfs/ etc/ [ tekkamanninja@Tekkaman- Ninja etc] $ su 口令： [ root@Tekkaman- Ninja etc] # cp / etc/ passwd . ; cp / etc/ shadow . ; cp / etc/ group . [ root@Tekkaman- Ninja etc] # kwrite passwd root: x: 0: 0: root: / root: / bin/ sh [ root@Tekkaman- Ninja etc] # kwrite group

root: x: 0: root [ root@Tekkaman- Ninja etc] # kwrite shadow root: $ 1$N8K8eEQe$. XkJo3xcsjOE6vo1jW9Nk/ : 13923: 0: 99999: 7: : : [ root@Tekkaman- Ninja etc] # rm * ~ rm：是否删除普通文件 “group~ ”? y rm：是否删除普通文件 “passwd~ ”? y rm：是否删除普通文件 “shadow~ ”? y [ root@Tekkaman- Ninja etc] # exit exit [ tekkamanninja@Tekkaman- Ninja etc] $

这 3 个文件是从Host 中拷贝过来的，只留下root 帐号。

那么现在 root的登陆密码和Host的登陆口令一致了，可以登录后再修改以及创建新用户。( 若使用以上文件，则root 密码为 tekkaman )

拷贝必需的动态库文件

[ tekkamanninja@Tekkaman- Ninja lib] $ cp - d / home/ tekkamanninja/ working/ gcc4. 1. 1/ gcc- 4. 1. 1- glibc- 2. 3. 2/ arm- 9tdmi- linux- gnu/ arm- 9tdmi- linux- gnu/ lib/ ld* . cp: 略过目录 “/ home/ tekkamanninja/ working/ gcc4. 1. 1/ gcc- 4. 1. 1- glibc- 2. 3. 2/ arm- 9tdmi- linux- gnu/ arm- 9tdmi- linux- gnu/ lib/ ldscripts” [ tekkamanninja@Tekkaman- Ninja lib] $ cp / home/ tekkamanninja/ working/ gcc4. 1. 1/ gcc- 4. 1. 1- glibc- 2. 3. 2/ arm- 9tdmi- linux- gnu/ arm- 9tdmi- linux- gnu/ lib/ libc- 2. 3. 2. so . ; cp - d / home/ tekkamanninja/ working/ gcc4. 1. 1/ gcc- 4. 1. 1- glibc- 2. 3. 2/ arm- 9tdmi- linux- gnu/ arm- 9tdmi- linux- gnu/ lib/ libc. so. 6 .

以上是最基本的文件。

一个最基本根文件系统构建完成！未压缩的文件系统总大小不到3M 。
