通過Cobbler實作自動化安裝FreeBSD

 1. 挂載freebsd鏡像

mount -t iso9660 -o loop freebsd-8.3-release-amd64-disc1.iso  /mnt

2. 導入鏡像檔案到cobbler

cobbler import --name=freebsd-8.3 --arch=x86_64 --path=/mnt

我們在導入過程中可能會提示task failed

可以忽略

3. 修改loader.conf

echo vfs.root.mountfrom=\"ufs:/dev/md0\" >> /var/www/cobbler/ks_mirror/freebsd-8.3-x86_64/boot/loader.conf

echo vfs.root.mountfrom.options=\"rw\" >> /var/www/cobbler/ks_mirror/freebsd-8.3-x86_64/boot/loader.conf

4. 挂載mfsroot.gz

将/var/www/cobbler/ks_mirror/freebsd-8.3-x86_64/boot/mfsroot.gz拷貝到一台freebsd機器上後，執行如下指令

gzip -d mfsroot.gz

mdconfig -atvnode -f mfsroot

mount /dev/md0 /mnt

5. 建立自動安裝配置檔案install.cfg

cd /mnt

cat > install.cfg < < eof

debug=yes

noninteractive=yes

noconfirm=yes

nowarn=yes

disk=mfid0

partition=all

bootmanager=standard

diskpartitioneditor

mfid0s1-1=ufs 0 /

disklabeleditor

trydhcp=yes

netdev=bce0

hostname=tfreebsd

distsetminimum

nfs=1.1.1.1:/var/www/cobbler/ks_mirror/freebsd-8.3-x86_64

mediasetnfs

installcommit

shutdown

eof

6. 将install.cfg合并到mfsroot

cd ~

umount /mnt

mdconfig -d -u0

gzip mfsroot

再通過網絡傳輸到cobbler伺服器覆寫原/var/www/cobbler/ks_mirror/freebsd-8.3-x86_64/boot/目錄下的mfsroot.gz檔案

7. 安裝配置nfs伺服器

# 預設freebsd的網絡引導程式pxeboot隻支援nfs，如果想支援tftp需要自行重新編譯這個程式

yum install -y nfs-utils

echo "/var/www/cobbler/ks_mirror/freebsd-8.3-x86_64 *(ro,root_squash)" > /etc/exports

/etc/init.d/rpcbind start

/etc/init.d/nfs start

8. 更改cobbler的dhcp模闆檔案dhcp.template

# ******************************************************************

# cobbler managed dhcpd.conf file

#

# generated from cobbler dhcp.conf template ($date)

# do not make changes to /etc/dhcpd.conf. instead, make your changes

# in /etc/cobbler/dhcp.template, as /etc/dhcpd.conf will be

# overwritten.
