PXE 安装UOS 提示NFS over TCP not available from 10.x.x.x
问题：pxe使用nfs安装的时候提示 NFS over TCP not available from ip
解决方案：
1.在grup.cfg修改红色内容
linux /debian-install/amd64/live/vmlinuz console=tty boot=live ethdevice-timeout=120 ip=dhcp netboot=nfs nfsroot=x.x.x.x:/data/nfs/amd64/ components union=overlay locales=zh_CN.UTF-8 livecd-installer --
- systemctl restart rpcbind && systemctl restart nfs-kernel-server
