二、OpenWRT简介
OpenWRT（曾用名 LEDE）是一款广泛应用于路由器的嵌入式操作系统。本站提供 OpenWRT 的包管理器 opkg的镜像，以加快国内访问速度。
三、使用VM虚拟机安装OpenWRT操作步骤
1、下载OpenWRT.img镜像源
下载地址：https://mirrors.aliyun.com/openwrt
2、将.img镜像文件转换成.vmdk虚拟硬盘格式文件
所需工具为：StarWind V2V Image Converter
（1）打开StarWind V2V Image Converter
（2）选择将要转换的镜像文件存储的位置
（选择Local file）本地文件夹
（3）选择源镜像文件
（4）选择转换格式
（5）选择磁盘格式
（6）确认信息，开始转换
（7）转换完成
3、使用VM虚拟机创建OpenWRT
部分关键截图如下图所示
① 选择的客户机操作系统如下图所示
② 使用NAT地址转换模式
③ 选择磁盘，为刚刚转换过后的.vmdk磁盘格式文件
④ 创建完成，点击“开启此虚拟机”
⑤ 登录成功
4、修改网络参数信息并SSH连接
root@OpenWrt:~# vi /etc/config/network root@OpenWrt:~# cat /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 'fd33:8f52:e9fd::/48' config device option name 'br-lan' option type 'bridge' list ports 'eth0' config interface 'lan' option device 'br-lan' option proto 'static' option ipaddr '192.168.200.50' option netmask '255.255.255.0' option ip6assign '60' root@OpenWrt:~# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master br-lan state UP qlen 1000 link/ether 00:0c:29:b4:2f:04 brd ff:ff:ff:ff:ff:ff 5: br-lan: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000 link/ether 00:0c:29:b4:2f:04 brd ff:ff:ff:ff:ff:ff inet 192.168.200.50/24 brd 192.168.200.255 scope global br-lan valid_lft forever preferred_lft forever inet6 fd33:8f52:e9fd::1/60 scope global noprefixroute valid_lft forever preferred_lft forever inet6 fe80::20c:29ff:feb4:2f04/64 scope link valid_lft forever preferred_lft forever root@OpenWrt:~# _________________________________________________________________ C:\Users\xybdiy>ssh root@192.168.200.50 The authenticity of host '192.168.200.50 (192.168.200.50)' can't be established.

5、访问OpenWRT的WEB界面，输入配置的IP地址即可
四、更换阿里OpenWRT镜像源
手工替换
登录到路由器，并编辑 /etc/opkg/distfeeds.conf文件，
将其中的downloads.openwrt.org 替换为 **mirrors.aliyun.com/openwrt`**即可。
快捷替换
执行如下命令自动替换
sed -i 's_downloads.openwrt.org_mirrors.aliyun.com/openwrt_' /etc/opkg/distfeeds.conf
操作过程如下：
root@OpenWrt:~# cat /etc/opkg/distfeeds.conf src/gz openwrt_core https://downloads.openwrt.org/releases/21.02.1/targets/x86/64/packages src/gz openwrt_base https://downloads.openwrt.org/releases/21.02.1/packages/x86_64/base src/gz openwrt_luci https://downloads.openwrt.org/releases/21.02.1/packages/x86_64/luci src/gz openwrt_packages https://downloads.openwrt.org/releases/21.02.1/packages/x86_64/packages src/gz openwrt_routing https://downloads.openwrt.org/releases/21.02.1/packages/x86_64/routing src/gz openwrt_telephony https://downloads.openwrt.org/releases/21.02.1/packages/x86_64/telephony root@OpenWrt:~# sed -i 's_downloads.openwrt.org_mirrors.aliyun.com/openwrt_' /etc/opkg/distfeeds.conf root@OpenWrt:~# cat /etc/opkg/distfeeds.conf src/gz openwrt_core https://mirrors.aliyun.com/openwrt/releases/21.02.1/targets/x86/64/packages src/gz openwrt_base https://mirrors.aliyun.com/openwrt/releases/21.02.1/packages/x86_64/base src/gz openwrt_luci https://mirrors.aliyun.com/openwrt/releases/21.02.1/packages/x86_64/luci src/gz openwrt_packages https://mirrors.aliyun.com/openwrt/releases/21.02.1/packages/x86_64/packages src/gz openwrt_routing https://mirrors.aliyun.com/openwrt/releases/21.02.1/packages/x86_64/routing src/gz openwrt_telephony https://mirrors.aliyun.com/openwrt/releases/21.02.1/packages/x86_64/telephony root@OpenWrt:~#
五、问题反馈
暂未解决使用VM虚拟机创建的OpenWRT系统，使其能够访问外网，已经尝试多种方法，依旧不行。问题留存，待解决。
