背景：
官网下载Ubuntu镜像安装，交互模式需要手动配置很多东西，为了快速安装，特制作自动安装镜像，方便安装系统。
以下方法是参照已经做好的12.04自动安装镜像修改16.04的镜像，最终成功，此配置方法应该是普适的。
制作方法：
下载官网镜像iso文件：ubuntu-16.04.4-server-amd64.iso （http://mirrors.zju.edu.cn/ubuntu-releases/16.04/ubuntu-16.04.4-server-amd64.iso）
cd /root/ wget http://mirrors.zju.edu.cn/ubuntu-releases/16.04/ubuntu-16.04.4-server-amd64.iso mkdir mnt mount ubuntu-16.04.4-server-amd64.iso mnt/ cp -rf ./mnt/* ./mnt/.disk/ ./ubuntu/ #将挂载的镜像目录copy到ubuntu目录中
将镜像文件拷贝出来后，根据以下链接修改相关配置文件：

1.用以下内容替换isolinux.cfg文件内容（相关说明见上面链接）
cp ubuntu/isolinux/isolinux.cfg{,.bak}
default autoinstall prompt 0 timeout 100 menu title Custom Live CD menu background splash.png menu color title 1;37;44 #c0ffffff #00000000 std label autoinstall menu label autoinstall - auto install ubuntu kernel /install/vmlinuz append initrd=/install/initrd.gz file=/cdrom/preseed/ubuntu-server.seed boot=install debian-installer/locale=en_US console-setup/ask_detect=false keyboard-configuration/layoutcode=us automatic-ubiquity quiet splash --
2.用以下内容替换ubuntu-server.seed文件内容（相关说明见上面链接）
cp ubuntu/preseed/ubuntu-server.seed{,.bak}
#locate d-i debian-installer/locale string en_US d-i console-tools/archs select true d-i debian-installer/language string en d-i debian-installer/country string us d-i localechooser/supported-locales multiselect en_US.UTF-8,zh_CN.UTF-8 #keyboard d-i console-setup/ask_detect boolean false d-i console-configuration/layoutcode string us d-i keyboard-configuration/modelcode string SKIP #clock d-i clock-setup/utc boolean false d-i time/zone string Asia/Shanghai #network d-i netcfg/choose_interface select auto d-i netcfg/dhcp_Failed note d-i netcfg/dhcp_options select Do not configure the network at this time d-i netcfg/get_hostname string cc d-i netcfg/get_domain string cc-domain d-i netcfg/wireless_wep string # Mirror d-i pkgsel/language-pack-patterns string d-i pkgsel/install-language-support boolean false d-i apt-setup/partner boolean true d-i debian-installer/splash boolean false d-i oem-config-udeb/frontend string debconf d-i mirror/http/proxy string # clock d-i clock-setup/ntp boolean true #user d-i passwd/root-login boolean false #d-i passwd/root-password password 123 #d-i passwd/root-password-again password 123 d-i passwd/make-user boolean true d-i passwd/user-fullname string leo ##用户名 d-i passwd/username string leo ##用户名 d-i passwd/user-password password 123 ##密码 d-i passwd/user-password-again password 123 d-i user-setup/allow-password-weak boolean true d-i user-setup/encrypt-home boolean false #basic system #d-i base-installer/kernel/linux/initramfs-generators string yaird #package tasksel tasksel/first multiselect ubuntu-desktop d-i pkgsel/include string openssh-server build-essential vim landscape-common d-i pkgsel/update-policy select none #grub d-i grub-installer/only_debian boolean true d-i grub-installer/with_other_os boolean true # Finish d-i finish-install/reboot_in_progress note oem-config oem-config/steps multiselect language,timezone,keyboard,user,network,tasksroot
修改完毕后，将ubuntu目录重新打包成iso镜像
mkisofs 命令使用参考这里（http://man.linuxde.net/mkisofs）
mkisofs -R -J -T -v -no-emul-boot -boot-load-size 4 -boot-info-table -b isolinux/isolinux.bin -c isolinux/boot.cat -o auto-ubuntu-16.04.4-server-amd64.iso ubuntu/
生成的可以自动安装的iso镜像为：auto-ubuntu-16.04.4-server-amd64.iso
完毕。
