目的：在家搭建一个自己私有NAS，不是配置路由器。

硬件环境：联想瘦客户机。

软件版本：openwrt-21.02.2-x86-64-generic-ext4-combined-efi.img.gz

创建系统：用U盘启动瘦客户机，使用”IMG写盘工具.exe“将镜像写入瘦客户机的SSD中，然后就可从SSD上启动瘦客户机。

一.重新创建镜像

  1. 在虚拟机中安装ubuntu桌面版

ubuntu-21.10-desktop-amd64

  1. 安装相关依赖包
sudo apt install build-essential libncurses5-dev libncursesw5-dev \
zlib1g-dev gawk git gettext libssl-dev xsltproc rsync wget unzip python
  1. 获取Image Builder
wget https://downloads.openwrt.org/releases/21.02.2/targets/x86/64/openwrt-imagebuilder-21.02.2-x86-64.Linux-x86_64.tar.xz
  1. 解压压缩包，并进入解压目录
tar -J -x -f openwrt-imagebuilder-*.tar.xz
cd openwrt-imagebuilder-*/
  1. 修改为国内镜像源，提高创建镜像的速度

清华大学：mirrors.tuna.tsinghua.edu.cn/openwrt

中科大：mirrors.ustc.edu.cn/openwrt

腾讯：mirrors.cloud.tencent.com/openwrt

cp repositories.conf  repositories.conf.bak
vi repositories.conf
  1. 可以使用下列变量自定义镜像 The image building can be customized with the following variables:

Variable变量名

Description描述

​​PROFILE​​

Specifies the target image to build

​​PACKAGES​​

A list of packages to embed into the image

​​FILES​​

Directory with custom files to include

​​BIN_DIR​​

Alternative output directory for the images

​​EXTRA_IMAGE_NAME​​

Add this to the output image filename (sanitized)

​​DISABLED_SERVICES​​

The names of services from ​​/etc/init.d​​​ to disable, e.g. ​​dhcp​​ for dnsmasq

  1. 创建镜像

原根目录尺寸仅104M。保留其它参数不变，仅修改根目录尺寸。

cp .config .config.bak
vi .config
...修改内容
CONFIG_TARGET_KERNEL_PARTSIZE=16
CONFIG_TARGET_ROOTFS_PARTSIZE=960
...

make clean
make image

当rootfs设置尺寸大于1G时，make imge报错，不知道什么原因！！！

二 网卡IP配置

设置静态地址。网关和DNS直接设成自己路由器的网关地址.

配置文件路径/etc/config/network


config interface 'loopback'
        option device 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config globals 'globals'
        option ula_prefix 'fd00:000f:d776::/48'

config interface 'lan'
        option ifname 'eth0'
        option proto 'static'
        option ipaddr '192.168.1.100'
        option netmask '255.255.255.0'
        option gateway '192.168.1.1'
        option dns '192.168.1.1'
        option ip6assign '60'

然后重启网卡

#/etc/init.d/network restart

三. 安装软件包

  1. 安装fdisk
root@OpenWrt:# opkg update
root@OpenWrt:# opkg install fdisk
