Installing Caddy\"Caddy<\/a><\/h3>\n

Download Caddy<\/a> from the official website.<\/p>\n

Give the executable root permissions1<\/sup>:<\/p>\n

$ chown root .\/caddy\r\n$ chmod +s .\/caddy<\/code><\/pre>\n
Caddyfile<\/h3>\n
Caddy reads it configuration for the Caddyfile<\/em>. More information can be found in the official documentation<\/a>.<\/p>\n
Launchd config<\/h3>\n
Create a launchd<\/em> plist file: ~\/Library\/LaunchAgents\/com.caddyserver.web.plist<\/code>. This file should look like this:<\/p>\n

The launchd script will stop the built-in Apache server on macOS X, set the ulimit<\/code> and execute Caddy. The Caddy command line arguments are quite trivial:<\/p>\n
    \n
  1. -agree<\/code>: agree to the CA’s (Let’s Encrypt) Subscriber Agreement.<\/li>\n
  2. -email<\/code>: your email address used for the certificates authority.<\/li>\n
  3. -conf<\/code>: full path to your Caddyfile.<\/li>\n<\/ol>\n
    The launchd file will make sure that Caddy is started at boot and kept alive.<\/p>\n
    Start and Stop Caddy launchd service using the following commands:<\/p>\n
    $ launchctl load ~\/Library\/LaunchAgents\/com.caddyserver.web.plist\r\n$ launchctl unload ~\/Library\/LaunchAgents\/com.caddyserver.web.plist<\/code><\/pre>\n
    \n
      \n
    1. Yes, I know, it’s not good practice to run a service as root. But there is no other decent way on OS X. setcap<\/code> doesn’t exist on macOS. Since Caddy won’t be touching any files, and Caddy doesn’t execute shell script, there is not a lot that can go wrong in this case. If you feel uncomfortable running Caddy as root, you could use portforwarding in your firewall and listen on a port >= 1024, for which you won’t need root privileges. This can be done using this command:\n
      echo \"\r\nrdr pass inet proto tcp from any to any port 80 -> 127.0.0.1 port 8080\r\n\" | sudo pfctl -ef -<\/code><\/pre>\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
