openwrt的各种玩法

1. 想要所有设备科学上网，不需要有wifi功能的新硬件

你只需要一个能运行openwrt的硬件，然后设置你设备的默认网关为openwrt设备即可。

2. openwrt也可以的容器中运行

$ docker import http://downloads.openwrt.org/attitude_adjustment/12.09/x86/generic/openwrt-x86-generic-rootfs.tar.gz openwrt-x86-generic-rootfs
$ docker images
REPOSITORY                           TAG                   IMAGE ID            CREATED             VIRTUAL SIZE
openwrt-x86-generic-rootfs           latest                2cebd16f086c        6 minutes ago       5.283 MB

$ docker run -i openwrt-x86-generic-rootfs -name openwrt /sbin/init
$ docker exec -it openwrt /bin/ash

raspberry pi 3B :https://archive.openwrt.org/releases/21.02.2/targets/bcm27xx/bcm2710/openwrt-21.02.2-bcm27xx-bcm2710-rpi-3-ext4-factory.img.gz

docker install

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh ./get-docker.sh

3. openwrt的树莓派镜像可以用rpi-imager安装

https://firmware-selector.openwrt.org/?version=21.02.0&target=bcm27xx%2Fbcm2710&id=rpi-3

4. rpi-imager在linux下失败可以去windows下试试

Linux下的USB可能有些问题，可能是缓冲区太大了。

组网

@startuml
!include <office/Servers/application_server>
!include <office/Servers/database_server>
nwdiag {
  network chinamobile {

      router [address = "210.x.x.1", description="<&wifi*4>"];
      other_routers [address = "x"];
  }
  network internal {
      address = "192.168.1.0/24";

      router [address = "192.168.1.1"];
      rpi [address = "192.168.1.10"， description="<&wifi*4>\n rpi"];
      phone1 [description="<&phone*4>\n phone\n gw=192.168.1.10"];
      phone2 [description="<&tablet*4>\n tablet\n gateway=192.168.1.10"];
      pc [description="<$database_server>\n pc"];
      macbook [description="<&laptop*4>\n laptop"];
  }
}
