Reference configuration for caddy2 server

[Kent Hulick]

I've created a Caddyfile to enable using Caddy2 as the web server, and thought I would share. I'd suggest adding this as mythweb.conf.caddy.

# The Caddyfile is an easy way to configure your Caddy web server.
#
# Unless the file starts with a global options block, the first
# uncommented line is always the address of your site.
#
# To use your own domain name (with automatic HTTPS), first make
# sure your domain's A/AAAA DNS records are properly pointed to
# this machine's public IP, then replace ":80" below with your
# domain name.

# Global options https://caddyserver.com/docs/caddyfile/options
{
	auto_https off
	admin off
	log {
		output file /var/log/caddy/caddy.log {
			roll_size 50
			roll_keep 5
			roll_keep_for 2d
		}
		format console
		level INFO
		#level   DEBUG
	}
}

:8080 {
	# Set this path to your site's directory.
	root * /usr/share/caddy/mythweb

	# Add trailing slash for directory requests
	@canonicalPath {
		file {path}/mythweb.php
		not path */
	}
	redir @canonicalPath {path}/ 308

	# Enable the static file server.
	file_server

	# rewrite rules
	@myth_do_nothing {
		path_regexp myth_do_nothing_reg ^/(css|data|images|js|themes|skins|[a-z_]+\.(php|pl)).*
	}
	@myth_perl {
		path_regexp myth_perl_reg ^/(pl(/.*)?)$
	}
	@myth_php {
		path_regexp myth_php_reg ^/(.+)$
	}
	handle @myth_do_nothing {
		#do nothing but keep other handlers from running
		#rewrite @myth_do_nothing {http.regexp.myth_do_nothing_reg.0}
	}
	handle @myth_perl {
		rewrite @myth_perl /mythweb.pl/{http.regexp.myth_perl_reg.1}
	}
	handle @myth_php {
		rewrite @myth_php /mythweb.php/{http.regexp.myth_php_reg.1}
	}
	handle * {
		rewrite * mythweb.php
	}

	# Proxy PHP files to the FastCGI responder
	@phpFiles path *.php*
	reverse_proxy @phpFiles unix//run/php/php7.4-fpm.sock {
		transport fastcgi {
			split .php
			env db_server localhost
			env db_name mythconverg
			env db_login mythtv
			env db_password mythtv
		}
	}
}
