首先我们在openwrt.ai上构建一个固件

(下图案例)

定制软件包

-zram-swap luci-app-lucky luci-app-daed luci-app-diskman cfdisk luci-app-netdata luci-app-store luci-app-turboacc luci-app-wrtbwmon luci-theme-argon btop docker-compose luci-app-argon-config jq bpftool-full zoneinfo-all

这里的初始化自定义shell作用是

设置全局倒计时1秒删掉默认的ip 改成DHCP 重启网络

uci set luci.apply.holdoff='1'
uci commit luci
uci delete network.lan.ipaddr
uci delete network.lan.netmask
uci set network.lan.proto='dhcp'
uci commit network
/etc/init.d/network restart

针对某些DNS挟持不了的机子重启网络

uci set dhcp.lan.start='120'  # 将 DHCP 地址池起始位置设置为 172.16.0.120
uci set dhcp.lan.limit='150'  # 限制 DHCP 地址池大小为 150
uci commit dhcp
/etc/init.d/dnsmasq restart

我们需要一台云服务器安装好Ubuntu系统

随后我们通过 VNC 远程链接服务器

进入后台后查看自己的ip地址

ip addr

到openwrt.ai构建一个系统镜像(设备选择X86_64 把ip地址填上去)

注意我这里是/20的掩码换算过来就是255.255.240.0(不懂的话度娘)

系统初始化脚本的意思是
设置全局更改倒计时为1秒删除默认地址默认掩码将网络变成成自动获取地址重启网络

uci set luci.apply.holdoff='1'
uci commit luci
uci delete network.lan.ipaddr
uci delete network.lan.netmask
uci set network.lan.proto='dhcp'
uci commit network
/etc/init.d/network restart

然后点击构建新固件

等待他构建完成

好了以后点击下载

右键出来的固件复制地址

我们用一段命令完成解压 dd来重装

国内加速

https://raw.githubusercontent.com/leitbogioro/Tools/master/Linux_reinstall/InstallNET.sh

wget --no-check-certificate -qO InstallNET.sh 'https://gitee.com/mb9e8j2/Tools/raw/master/Linux_reinstall/InstallNET.sh' && chmod a+x InstallNET.sh

bash InstallNET.sh --nomemcheck -dd +刚刚复制的链接(把我删掉替换)

把脚本里的源换成中国的镜像

sed -i "s/export IsCN=''/export IsCN='cn'/" InstallNET.sh

低内存机

https://raw.githubusercontent.com/bin456789/reinstall/main/reinstall.sh

curl -O https://cnb.cool/bin456789/reinstall/-/git/raw/main/reinstall.sh || wget -O reinstall.sh $_ && chmod a+x reinstall.sh

bash reinstall.sh dd --img

备用命令解压并dd安装

zip_file=$(find . -maxdepth 1 -name "*.img.gz" | head -n 1) \
&& [ -n "$zip_file" ] && gunzip "$zip_file" && \
img_file=$(find . -maxdepth 1 -name "*.img" | head -n 1) && [ -n "$img_file" ] && \
dd if="$img_file" of=/dev/vda bs=4M conv=fdatasync status=progress && \
dd if=/dev/zero of=/dev/sda bs=4M seek=244 conv=notrunc status=progress
