10/11/21: This article does not explain every step well but may be useful so I’m posting it.

Add the following to the root crontab: screen -d -m bash /home/josh/caddystart

Create a bash script that launches Caddy with your Caddyfile.

Create a Caddyfile in same directory you put your script in:

blog.joshmudge.com
tls myemail@email.com

root * /var/www/wordpress
php_fastcgi unix//run/php/php7.4-fpm.sock
#php_fastcgi localhost:9000
#log {
#output file /home/josh/log.txt
#}
#php_fastcgi 127.0.0.1:9000

# Prevent malicious PHP uploads from running
@uploads {
path_regexp path /uploads\/(.*)\.php
}
rewrite @uploads /

@wp-admin {
path not ^\/wp-admin/*
}
rewrite @wp-admin {path}/index.php?{query}
file_server

I did have to install php-fpm and configure wordpress.
