先从官方上获取ubuntu core的tar包：http://cdimage.ubuntu.com/ubuntu-base/releases/16.04/release/
选择下载ubuntu-base-16.04-core-armhf.tar.gz，下载完之后，创建临时文件夹并解压根文件系统：
mkdir tmp sudo tar -xf ubuntu-base-16.04-core-armhf.tar.gz -C tmp/
sudo cp -b /etc/resolv.conf tmp/etc/resolv.conf
cp /usr/bin/qemu-arm-static tmp/usr/bin/
sudo vim tmp/etc/apt/source.list 将下面的两行的注释取消掉： deb http://ports.ubuntu.com/ubuntu-ports/ xenial universe deb-src http://ports.ubuntu.com/ubuntu-ports/ xenial universe
sudo chroot tmp/
apt update
apt upgrade
apt install udev #否则ttyAMA0无法找到 apt install vim #vim编辑器 apt install net-tools #ifconfig，netstat，route，arp等 apt install iputils-ping #ping apt install sudo #sudo命令 #apt install ssh #ssh的client和server apt install ethtool #ethtool命令，显示、修改以太网设置 #apt install wireless-tools #iwconfig等，显示、修改无线设置 apt install ifupdown #ifup，ifdown等工具 #apt install network-manager #Network Manager服务和框架，高级网络管理 apt install iputils-ping #ping和ping6 apt install rsyslog #系统log服务 apt install bash-completion #bash命令行补全 apt install htop #htop工具，交互式进程查看器
useradd -s ‘/bin/bash‘ -m -G adm,sudo pengdl #增加pengdl用户 passwd pengdl #给pengdl用户设置密码 passwd root #修改root密码

编辑/etc/network/interfaces，添加如下内容：
auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.1.5 netmask 255.255.255.0 gateway 192.168.1.1
设置主机名称： echo "ubuntu-arm">/etc/hostname 设置本机入口ip： echo "127.0.0.1 localhost">>/etc/hosts echo "127.0.1.1 ubuntu-arm">>/etc/hosts
