Arch-Linux-reverse-proxy-for-ARM-and-x86_64

Arch Linux reverse proxy for ARM/Raspberry Pi and x86_64, incl WSL

Background

I have 2 Raspberry Pis, each running Arch Linux (https://archlinuxarm.org/), and several PCs running Arch (incl. Arch on WSL). (Because of the quarantine) I decided to reduce the load on the Arch servers and cache updated packages locally (on a RPi), for Arch running on RPi and PC.

Instructions

I applied the instructions from the Arch wiki for Dynamic reverse proxy cache using nginx, modifying the linked nginx pacman cache config.

As packages for Arch Linux on RPi and Arch Linux on x86_64 cannot be interchanged, I modified the location directives by matching the query with either /armv7h/ or /archlinux/. This match would determine the architecture of the system making the pacman query, /armv7h/ for RPi and /archlinux/ for x86_64. Inside these location directive blocks, processing would continue as described in the wiki section referenced above.

Please see my nginx.conf in this folder as an example.

Caution

1. Update the server_name
2. Update the proxy_pass directive with preferred mirrors that have the same $request_uri structure
3. Overtime you may find your preferred mirrors may need to be updated
4. If you add a http mirror, it may redirect to https. Note that these instructions do not handle redirections well.

Further work

1. Handle redirections.
2. Automatically update the mirrors.
