pacman-cache-server

Caching pacman mirror for faster downloads at home

Install from github

git clone https://github.com/antonilol/pacman-cache-server.git
cd pacman-cache-server
npm i
npm run build

Copy the sample config and edit it (optional)

cp config.sample.json config.json

Install from AUR

With an AUR helper, for example yay

yay -S pacman-cache-server-git

The config can be edited in /usr/lib/pacman-cache-server-git/ and the server can be started with systemd with

systemctl start pacman-cache-server

Usage

Start the server with

npm run start

On the clients, add

Server = http://<host>:<port>/$repo/os/$arch

at the top of /etc/pacman.d/mirrorlist

Replace <host> with the IP address of your server (or localhost if you run it on the same machine) and <port> with the http port specified in config.json (default: 8080)

This server redirects all requests to the mirror specified in config.json and saves a local copy of the file in cacheDir. When the next time the same file is requested, instead of asking the mirror for it, the local copy is given to the client.

By default, only *.pkg.tar.zst and *.pkg.tar.zst.sig are cached (this can be changed in config.json). It is not recommended to include *.db here because the package database changes without the filename changing.

To not get your disk at 100% somewhere in the future you can schedule a cron job to run pkgcacheclean every week/month. (Requires cacheDir to be set at pacman's cache dir /var/cache/pacman/pkg/)
