有了上篇IPXE的启动方法，我们来启动一个Ubuntu来玩：
简单的修改boot2.php即可：
case '\ec:f4:bb:d9:96:40':
$ip="172.16.36.2:172.16.37.254:255.255.254.0:myhost-16-36-2";
$ipa=explode(':',$ip);
echo "ifopen net0\n";
echo "set net0/ip $ipa[0]\n";
echo "set net0/netmask $ipa[2]\n";
echo "set net0/gateway $ipa[1]\n";
echo "set net0/dns $dns\n";
echo "kernel http://172.16.8.1/ks/ubuntu/vmlinuz.efi root=/dev/nfs boot=casper netboot=nfs nfsroot=172.16.11.6:/root/ubuntu ip=172.16.36.2::172.16.37.254:255.255.254.0:renhe-16-36-2:eno1 ro\n";
echo "initrd http://172.16.8.1/ks/ubuntu/initrd.lz\n";
echo "boot\n";
break;
注意：变的就是kernel和init那两行，netboot支持nfs和cifs，不支持http啊，试了半天！另外ip那一行，如果是动态的，ip=dhcp，如果是静态的，格式如下：
ip=客户端ip:服务器端ip:网关:掩码:主机名:网卡
服务器端ip不填，主机名也可以不填。
首先我们要去下个ISO
wget http://mirrors.163.com/ubuntu-releases/16.04/ubuntu-16.04-desktop-amd64.iso
然后把vmlinuz.efi和initrd.lz弄出来，放到[http://172.16.8.1/ks/ubuntu ]目录下
mount -o loop ubuntu-16.04-desktop-amd64.iso /mnt/iso
cp /mnt/iso/casper/vmlinuz.efi /var/www/html/ks/ubuntu
cp /mnt/iso/casper/initrd.lz /var/www/html/ks/ubuntu
然后建立nfs，把iso里的东西都弄到nfs共享里去：
mkdir -p /export/ubuntu
vi /etc/exports
/export/ubuntu *(rw,sync,no_subtree_check,fsid=0,no_root_squash)
yum install -y nfs-utils rpcbind
service nfs start
ok，启动pxe，就看到桌面了。
