Configure Caddy Server

---

Create directory for your website,

Replace caddy.domainhere.info with actual domain.

mkdir -p /var/www/html/caddy.domainhere.info

Open caddy /etc/caddy/Caddyfile configuration file and add your domain name and change website's directory,

vi /etc/caddy/Caddyfile

Replace 80 with your actual domain name and change the root directory

# 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.
:80 {
        # Set this path to your site's directory.
        root * /usr/share/

        # Enable the static file server.
        file_server

        # Another common task is to set up a reverse proxy:
        # reverse_proxy localhost:8080

        # Or serve a PHP site through php-fpm:
        # php_fastcgi localhost:9000
}

# Refer to the Caddy docs for more information:
# https://caddyserver.com/docs/caddyfile

Restart the Caddy Server using below command,

sudo systemctl reload caddy
