IPxe Boot step by step
- brctl addbr net
- ifconfig net 10.0.1.1/24 up
- edit the
dnsmasq.conf
likednsmasq.conf_pxe_boot
- /etc/init.d/dnsmasq start
- enable tftp server; then you should disable tftp-hpa service
service tftp-hpa stop
- configure the
interface
as your need - configure
dhcp-sequential-ip
get a ip in order - !! or you can use the command line to start the dnsmasq
/usr/sbin/dnsmasq -C /etc/dnsmasq.conf -x /var/run/dnsmasq/dnsmasq.pid -u dnsmasq -r /var/run/dnsmasq/resolv.conf -7 /etc/dnsmasq.d,.dpkg-dist,.dpkg-old,.dpkg-new --local-service
