先说说这次安装所基于的硬件环境:40G硬盘、1G内存,再加一个USB光驱。系统方面,Windows XP占10G(FAT32格式),FreeBSD占15G,剩下的都是自由空间。说白了,就是在一台已经装了双系统的机器上再塞进一个OpenBSD 3.6。
核心思路很简单:不用刻盘、不用U盘,直接从硬盘引导安装。具体步骤是这样的——
1. 先在C盘下建一个目录C:\OpenBSD3.6\i386,注意大小写不能错。然后把官方站点上i386目录下的所有文件都下载到这里。
2. 重启机器,进入Grub for DOS(没有的话先装一个),按 c 进入GRUB命令行模式,你会看到:
grub>
3. 接着输入下面三行命令,启动OpenBSD的安装程序:
grub>map (hd0,0)/OpenBSD3.6/i386/cdrom36.fs (fd0) grub>chainloader (hd0,0)/OpenBSD/i386/cdrom36.fs grub>rootnoverify (fd0) grub>boot
4. 这时候你已经成功进入OpenBSD的安装界面了,屏幕显示:
erase ^?, werase ^W, kill ^U, intr ^C, status ^T (I)nstall, (U)pgrade or (S)hell?
5. 按 i 开始安装。接下来是一串问答:
Terminal type? [vt220] 回车 Do you wish to select a keyboard encoding table? [no] 回车 Proceed with install? [no] yes Which one is the root disk? (or 'done') [wd0] 回车 Do you want to use *all* of wd0 for OpenBSD? [no] 回车
6. 这里就进入分区环节了。系统会把当前硬盘的分区表列出来,大致是下面这样:
Disk: wd0
geometry: 4864/255/63 [78140160 Sectors]
Offset: 0
Signature: 0xAA55
Starting Ending LBA Info:
#: id C H S - C H S [ start: size ]
------------------------------------------------------------------------
*0: 0C 0 1 1 - 1304 254 63 [ 63: 20964762 ] Win95 FAT32
1: A5 1305 0 1 - 3263 254 63 [ 20964825: 31471335 ] FreeBSD
2: A6 3264 0 1 - 4862 254 63 [ 52436160: 25687935 ] OpenBSD
3: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused
以及OpenBSD内部的disklabel:
16 partitions: # size offset fstype [fsize bsize cpg] a: 21494576 52436160 4.2BSD 2048 16384 16 # / b: 4209424 73930736 swap c: 25688880 52436160 unused 0 0 d: 78140160 0 unused 0 0 e: 20964762 63 MSDOS f: 31471335 20964825 unknown
注意一下:这里的 e 其实就是Windows XP的C盘,文件系统类型显示为MSDOS。
7. 确认分区后,系统会给出警告——接下来要格式化这些分区,所有数据都会被销毁。确认后继续:
The next step *DESTROYS* all existing data on these partitions! Are you really sure that you're ready to proceed? [no] yes System hostname? (short form, e.g. 'foo') # OpenBSD Configure the network? [yes] yes DNS domain name? (e.g. 'bar.com') [my.domain] com DNS nameserver? (IP address or 'none') [none] 202.96.128.68 Use the nameserver now? [yes] 回车 Edit hosts with ed? [no] 回车 Do you want to do any manual network configuration? [no] 回车 Password for root account? (will not echo) # 输入两次密码 Password for root account? (again)
8. 当问到“安装介质放在哪里”时,选择 disk:
Where are the install sets? (or 'done') d
然后选择硬盘设备:
A vailable disks are: wd0. Which one contains the install sets? (or 'done') [wd0] 回车
9. 接着指定分区,这里选择 e(也就是C盘所在的分区):
Partition? [a] e
10. 文件系统类型选 msdos:
Which filesystem type? [default] msdos
11. 输入路径的时候注意大小写:
Pathname to the sets? (or 'done') OpenBSD3.6/i386
12. 选择要安装的软件包。这里可以直接输入 all 全选,或者一一确认:
The following sets are a vailable. Enter 'all' to select all, or 'done'. File name? (or 'done') 回车 Ready to install sets? [yes] 回车 Where are the install sets? (or 'done') [done] 回车
13. 最后是安装后的配置——启动sshd、是否使用X Window、时区等:
Start sshd(8) by default? [yes] 回车
Do you expect to run the X Window System? [yes] no
What timezone are you in? ('?' for list) [Canada/Mountain] Asia/Shanghai
等所有包安装完成,重启系统,OpenBSD 3.6就正式入驻你的硬盘了。整个过程不依赖光驱或U盘,全靠Grub引导加载内核镜像,算是非常经典的硬盘安装方式。
