How to Use Caddy
·
1 min read
Caddy is simpler compared to Nginx and very convenient for server proxying, especially for obtaining HTTPS certificates.
Here are some common operations recorded.
Installation
It is recommended to use a package manager for installation, such as on Mac:
brew install caddy
On CentOS7:
yum install yum-plugin-copr
yum copr enable @caddy/caddy
yum install caddy
On Ubuntu:
sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https curl
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update
sudo apt install caddy
For installation on other OS, see https://caddyserver.com/docs/install#install
Common Commands
# Start service
caddy start --config ./Caddyfile
# Format config file
caddy fmt --overwrite
# Stop service
caddy stop

At the end
That’s all I know. I recommend learning from the official doc for more information on how to use it.
