阶段测试centos7网络安装...
如果希望提供centos7u2 centos6u6多个系统：
1. 为每个系统准备/var/lib/tftp/centosX/{vmlinuz,initrd}
2. 为每个系统准备引导菜单/var/lib/tftp/pxelinux.cfg/default
3. 为每个系统准备安装树/var/ftp/centosX
[root@tianyun tftpboot]# mkdir
centos7u2
[root@tianyun tftpboot]# mkdir centos6u6
[root@tianyun tftpboot]# ls centos6u6
vmlinuz initrd.img
[root@tianyun tftpboot]# ls centos7u2
vmlinuz initrd.img
3. 编辑多系统启动菜单
[root@tianyun tftpboot]# vim pxelinux.cfg/default
label centos6u6
menu label ^Install centos 6
menu default
kernel centos6u6/vmlinuz
append initrd=centos6u6/initrd.img
label centos7u2
menu label ^Install centos 7
kernel centos7u2/vmlinuz
append initrd=centos7u2/initrd.img inst.stage2=ftp://192.168.2.128/centos7u2 inst.repo=ftp://192.168.2.128/centos7u2
label rescue

append initrd=centos7u2/initrd.img rescue inst.stage2=ftp://192.168.2.128/centos7u2 inst.repo=ftp://192.168.2.128/centos7u2
