How to install YOURLS with caddy

Posted on Edited on In Views: Word count in article: 5.4k Reading time ≈ 5 mins.

YOURLS is an open-source program which can be used to shorten your url. It is a great url-shorten tool. However, the official instruction is only based on apache. For some specific reason, I must use caddy as my web server. Caddy and Apache cannot be used simultaneously as they occupy the same port. So I just try and succeed install YOURLS with caddy.

Environment

Debian12

caddy version: v2.7.5
