之前和友人聊天,知道可以利用PXE安裝虛擬機,相信很多用戶都和小編一樣還不是很清楚,在這小編就把學習到的方法分享給大家。
方法如下:
1.1 dnsmasq
apt-get install dnsmasq
vim /etc/dnsmasq.conf
bogus-priv
filterwin2k
interface=eth0
dhcp-range=192.168.100.172,192.168.100.180,12h
dhcp-host=52:54:00:ed:00:f7,192.168.100.178
dhcp-boot=pxelinux.0
enable-tftp
tftp-root=/var/ftpd
dhcp-authoritative
/etc/init.d/dnsmasq restart
注意:如果想要為pxe client分配固定IP,可使用dhcp-host參數.采用這種方式的好處是可以避免將已經網絡的IP搞亂。
如果使用KVM提供的虛機作為pxe client來測試時, 應該每測試一次新建一個虛機(千萬不能重復測試)。
1.2 PXE
mkdir /var/www/ubuntu
mount -o loop/bak//kvmimages/ubuntu-11.10-server-amd64.iso /mnt
cp /mnt/preseed/ubuntu-server.seed /var/www/ubuntu
cp -a /mnt/* /var/www/ubuntu
cp -r /mnt/install/netboot/* /var/ftpd/
vim /var/ftpd/pxelinux.cfg/default
default linux
label linux
kernel ubuntu-installer/amd64/linux
append ks=http://192.168.100.171/ubuntu/ks.cfg preseed/url=http://192.168.100.171/ubuntu/ubuntu-server.seed vga=normal initrd=ubuntu-installer/amd64/initrd.gz --
注意:上述ks,與preseed應該配置一個Web服務器指向/var/www/ubuntu目錄。 上一頁123下一頁共3頁

以上就是利用PXE安裝虛擬機的方法了。值得注意的一點是我們如果要用虛機為pxeclient測試的話,應每測試一次新建一個虛機。
