Homelab | 架构设计与实现-Low-level design---Proxmox

一介绍

关于 “架构设计与实现-High-level design”篇章里，云下部分，本地环境的实现包括 Proxmox 及其数个不同功能的 VM ，以及 VM 内的众多不同功能的 Docker 。

如下：

Proxmox ，安装及配置等等，功能众多而杂，可以类比 Vsphere
Debian VM ，这里作为主力 Linux 使用，有点 Ubuntu 的稳定版分支的意思，适合做生产环境下的系统
OpenMediaVault,一个开源轻量的 NAS 系统
OpenWrt,作为代理服务，供其他服务使用，非透明代理
Win10 ，一个图形化的工作台
一个树莓派，裸机运行，跑了多个 ARM 架构的 Docker 应用

二部署

1 Proxmox ，安装及配置

安装后，让能跑起来还是比较简单，这里说明下网络相关的配置，以我的环境为例，我是使用 wireless 连接网络。 Proxmox 7 (Debian 11 Bullseye) – How to setup WiFi network

root@pve01:~# cat /etc/network/interfaces
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

[scode type="blue"]配置逻辑：

无线网卡 wlp0s20f3 作为网关，通过前面配置的 wpa_supplicant 服务，连接家里 WiFi 网络
有线网卡是 enp1s0 ，桥接到 vmbr0 虚拟交换机
另一个虚拟交换机 vmbr999 ，用于连接其他 VM 网卡
其他虚拟网络网段配置源 NAT ，用于访问互联网
配置针对无线网卡 wlp0s20f3 的 NAT Server ，用于从外部网络方便直接访问 VM
