一目了然系列之 Centos7 ALFS 自动化构建 LFS 8.0

ALFS huahua 1170℃

0x00 介绍

相信大家做了那么半天的 LFS 都很累了是吧?今天新开一期 关于 LFS 的系列,这次用 ALFS 来做,这是一个自动话脚本,编译工具链和基础软件的编译这些部分的工作都由 ALFS 这个工具自动去,但是这个工具好在于自动化去做,坏也在于此。如果没做过 LFS 那这个没啥实际的意义,能够收获的只有引导部分的内容,能够了解 linux 的一个基本的组成。下面我就来说说具体该怎么做。这里我有参考到陈涛老师发布过的这方面的视频,原版的视频有 4 个,但是实际上现在还能看只有 3 个,所以参考意义对于初学者来说意义不大了。这里我修正了几个参考的文档中间的错误,让实验能够一次性的成功。下面我们开始动手做。ALFS 是 LFS 官方推出的一个项目,与 LFS 项目平行。官方地址 http://www.linuxfromscratch.org/alfs/

0x01 准备工作

任何事情都是一样先要把准备的工作做好,有了基本的条件了在做一些东西就方便的多了说说需要准备的东西。这里说一下,一直有人问我 linux 的命令的问题,这次我直接贴出来敲的命令还有返回的结果。这样一目了然,这里拿个例子来说一下,容易看,初学者好些时候不成功就是因为不知是在 root 下做,还是在普通的用户下面做。我写的#开头的带文字的内容都是注释。在 shell 里面 # 开头就是注释。

[root@localhost ~]# cat /etc/redhat-release 
CentOS Linux release 7.6.1810 (Core) 
# [root@localhost ~]# cat /etc/redhat-release 
# [root@localhost ~]
# root 是 用户名,这里用的是root
# localhost 是本地
# ~ 代表的目录是哪里,~ 代表当前用户的 home 目录
# # 代表是用的 root 账户,普通用户是 ~
# cat /etc/redhat-release  这是执行的命令
# CentOS Linux release 7.6.1810 (Core)  这是返回的结果

操作系统

这里我采用了 Centos 7 mini 安装,安装centos 7 的时候要空一部分空间出来不用留着给 ALFS 使用,安装的时候采用 ext4 不采用 LVM。

[root@localhost ~]# cat /etc/redhat-release 
CentOS Linux release 7.6.1810 (Core) 

内核默认的

[root@localhost ~]# uname -a
Linux localhost.localdomain 3.10.0-957.21.3.el7.x86_64 #1 SMP Tue Jun 18 16:35:19 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

默认安装的软件 可以看我的 LFS 这篇帖子 基础环境是一样的我就不复制粘贴了,这样没什么意义,我给大家说说不一样的东西就好了,其他的参考之前这个帖子就好了,Centos 7 安装 LFS 系统基础软件。我是按 LFS 8.4 准备的基础软件,亲测没有任何问题,可以用 ALFS 正常编译出来 LFS 8.0 .

安装几个 ALFS 必备的软件

yum -y install libxslt subversion ncurses-devel 

分区准备

我的分区依旧是用的一块硬盘 /dev/sda1 是 centos7 的根目录,/dev/sda2 是 swap。/dev/sda3 作为 ALFS 的根目录, /dev/sda4 作为 ALFS 的 swap。这样一个规划,sda3 用的 ext4 分区 30 G 大小,sda4 swap 4G 大小。

处理硬盘分区

[root@localhost ~]# fdisk /dev/sda
Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

# 写操作,把前面的操作写入分区表

The partition table has been altered!

Calling ioctl() to re-read partition table.

WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table. The new table will be used at
the next reboot or after you run partprobe(8) or kpartx(8)
Syncing disks.

[root@localhost ~]# partprobe 
# 更新分区表

做完分区以后,要 partprobe 来更新分区表,这样才能看见新分出来的 sda3 sda4分区。

格式化分区 sda3 和 swap

[root@localhost ~]# mkfs.ext4 /dev/sda3

[root@localhost ~]# mkswap /dev/sda4

分区挂载

创建文件夹 ALFS 下默认是 /mnt/build_dir

[root@localhost ~]# mkdir -pv /mnt/build_dir
mkdir: created directory ‘/mnt/build_dir’

更改宿主的 fstab 挂载 sda3 分区

vim /etc/fstab 
# 在最下面写上一行
/dev/sda3                                 /mnt/build_dir                ext4    defaults        0 0

然后测试一下

[root@localhost ~]# mount -a
# lsblk 可以查看挂载的情况
[root@localhost ~]# lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 119.2G  0 disk 
├─sda1   8:1    0    50G  0 part /
├─sda2   8:2    0     4G  0 part [SWAP]
├─sda3   8:3    0    30G  0 part /mnt/build_dir
└─sda4   8:4    0     4G  0 part 
[root@localhost ~]# 

设置环境变量

编辑 root 用户的环境变量

[root@localhost ~]# vim .bash_profile
# 在最后写入
export LFS=/mnt/build_dir

创建账户并配置

因为 ALFS 在编译的时候不能用 root 用户来做需要使用一个普通的账户来实现编译,但是在过程中会用到 sudo 来临时提取 root 权限,这里我们新建一个账户,改变一下配置文件,让它不需要输入密码来自动化(这个操作是官方的 ALFS 文档里面没有的)。这里我建一个 test 用户

[root@localhost ~]#  useradd test
# 创建用户 test
[root@localhost ~]# passwd test
# 给 test 加密码,我加的是一个一位数的弱密码,所以会有下面 BAD PASSWORD 的提示
Changing password for user test.
New password: 
BAD PASSWORD: The password is a palindrome
Retype new password: 
passwd: all authentication tokens updated successfully.

test用户 sudo 无密码。

[root@localhost ~]# echo "test ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers

切换到 test

[root@localhost ~]# su - test
[test@localhost ~]$ 
# 此时用户已经变成了 test

添加环境变量

[test@localhost ~]$ echo "export LFS=/mnt/build_dir" >> .bash_profile 

[test@localhost ~]$ source .bash_profile 
# 加载新写入的环境变量

# 验证一下
[test@localhost ~]$ echo $LFS
/mnt/build_dir


准备内核

这里我们让 ALFS 自动帮我们把内核编译好,这里就需要先做好了 内核的 config 文件,在 LFS 的文章里面说了,我们先不具体说内核的配置方法,后面会有一片详解。这里先采用默认的配置,让内核能够跑起来就可以。

下载内核文件

[test@localhost ~]$ wget https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.9.9.tar.xz

默认配置内核

[test@localhost linux-4.9.9]$ make defconfig

[test@localhost linux-4.9.9]$ make menuconfig
# 确保这项添加好
Device Drivers  --->
  Generic Driver Options  --->
   [ ] Support for uevent helper [CONFIG_UEVENT_HELPER]
   [*] Maintain a devtmpfs filesystem to mount at /dev [CONFIG_DEVTMPFS]

[test@localhost linux-4.9.9]$ cp .config  ~/config-x86_64-4.9.9
# 导出配置文件

编辑 fstab 切记这个 fstab 与 LFS 8.4 的不一样

[test@localhost ~]$ sudo vim fstablfs
# 写入下面的内容保存

# Begin /etc/fstab

# file system  mount-point  type     options             dump  fsck
#                                                              order
/dev/sda3     /             ext4    defaults            1     1

/dev/sda4     swap         swap     pri=1               0     0
proc           /proc        proc     nosuid,noexec,nodev 0     0
sysfs          /sys         sysfs    nosuid,noexec,nodev 0     0
devpts         /dev/pts     devpts   gid=5,mode=620      0     0
tmpfs          /run         tmpfs    defaults            0     0
devtmpfs       /dev         devtmpfs mode=0755,nosuid    0     0

# End /etc/fstab

下载 LFS 8.0 软件源代码

[test@localhost ~]$ wget http://ftp.lfs-matrix.net/pub/lfs/lfs-packages/lfs-packages-8.0.tar

准备ALFS文件

[test@localhost ~]$ svn co svn://svn.linuxfromscratch.org/LFS/tags/8.0
# 下载 LFS Book
[test@localhost ~]$ mv 8.0/ lfsbook/
# 下载好的改名为 lfsbook
sed -i 's/7ee67b16b345b43cd34ed481792169ed/3cb3d36089f2d6ab19c7c0f3282de1c5/g' ~/lfsbook/packages.ent

# 进入 lfsbook 文件夹,修改packages.ent文件中lfs-bootscripts-20150222.tar.bz2的md5值
# 7ee67b16b345b43cd34ed481792169ed 是错误的 修改为:3cb3d36089f2d6ab19c7c0f3282de1c5
# 这个值在下载好的源码的 md5sums 这个文件里面有

[test@localhost ~]$ tar xf lfs-packages-8.0.tar 
# 解压所有程序的源码 这个解压完名字就是 8.0 的一个文件夹
[test@localhost ~]$ wget http://www.linuxfromscratch.org/alfs/downloads/jhalfs/stable/jhalfs-2.4.tar.xz

# 下载文件

[test@localhost ~]$ tar xf jhalfs-2.4.tar.xz 
[test@localhost ~]$ cd jhalfs-2.4
# 开始设置

[test@localhost jhalfs-2.4]$ sudo make

To be able to boot your new system you need to follow
the next steps:

    - Mount the virtual kernel file systems.

    - Enter to the chroot using the command found
    in the section -Entering the Chroot Environment-
    except if building CLFS with METHOD=boot.

    - Set a password for the root user.

    - Edit or create /etc/fstab,
                     /etc/hosts,
                     /etc/sysconfig/clock,
                     /etc/sysconfig/console,
                     /etc/sysconfig/network,
                     /etc/sysconfig/ifconfig.eth0,
                     /etc/resolv.conf
    and any other configuration file required to suit your needs.

    - Set-up the boot loader, except if building CLFS with METHOD=boot.

    You can set-up the new boot-loader installed on the new system
    or the host bootloader.

    If the last, it is better to exit first from the chroot.

    - Exit from the chroot and umount the filesystems.

If you are an experienced LFS user, several of those steps can be
skipped or done in a different way. But then, that is something
that you already know and there is no need to discuss it here.

编辑或创建文件

- Edit or create /etc/fstab,
                     /etc/hosts,
                     /etc/sysconfig/clock,
                     /etc/sysconfig/console,
                     /etc/sysconfig/network,
                     /etc/sysconfig/ifconfig.eth0,
                     /etc/resolv.conf

一项一项来,fstab是我们以前做好的。检查一下就好了

root:/# cat /etc/fstab
# Begin /etc/fstab

# file system  mount-point  type     options             dump  fsck
#                                                              order

devtmpfs       /dev         devtmpfs mode=0755,nosuid    0     0


# End /etc/fstab
root:/# 

编辑 hosts 保留一行就行了

root:/# vim /etc/hosts
root:/# cat /etc/hosts
# Begin /etc/hosts (network card version)

127.0.0.1 localhost

# End /etc/hosts (network card version)

编辑 hostname 内容随便写

root:/# vim /etc/hostname 
root:/# cat /etc/hostname 
ivoivo

/etc/sysconfig/clock 文件,只对 hwclock 有效,硬件时间不影响启动,有需要的话可以编辑,这里我就不做了。

/etc/sysconfig/console 参考以前的 LFS 的文章,没必要必须做,默认不影响启动,有需要的话根据 LFS 的书籍去更改

/etc/sysconfig/network 在配置文件中配置或修改网关和DNS 修改网关,可以理解为是一个总的配置文件,负责配置通用的网络配置方面

编辑一下 /etc/resolv.conf

root:/# cat /etc/resolv.conf
# Begin /etc/resolv.conf

nameserver 8.8.8.8
nameserver 114.114.114.114

# End /etc/resolv.conf

好了,一切都结束了,重启就可以了。由于内核的原因网卡启动找不到,下一期我们说说内核编译。就事重新编译一个内核替换过去。好了这期就到这了。感谢收看。
