sudo chown -R root:www-data /etc/caddy

• 配置ssl证书目录

sudo mkdir /etc/ssl/caddy
sudo chown -R www-data:root /etc/ssl/caddy
sudo chmod 0770 /etc/ssl/caddy

• 配置网站目录

sudo mkdir /var/www
sudo chown www-data:www-data /var/www

• 配置 systemd

sudo curl -s  https://raw.githubusercontent.com/mholt/caddy/master/dist/init/linux-systemd/caddy.service  -o /etc/systemd/system/caddy.service

sudo systemctl daemon-reload
sudo systemctl enable caddy.service
sudo systemctl status caddy.service

• 配置Caddfile配置文件

     修改Caddfile文件

vi /etc/caddy/Caddyfile

    一个简单的websocket加静态网站配置

www.google.com
{
  log /var/log/caddy/access.log
  tls google@gmail.com
  proxy /caressr 127.0.0.1:10000 {
    websocket
    header_upstream -Origin
  }
  root /var/www/
}

    给log路径赋权

sudo chown www-data:www-data /var/log/caddy

上例是一个简单的websocket加静态网站配置。第一行为自己的域名，tls后面加上邮箱会自动申请let’sencrypt ssl证书。Caddfile更多配置详见官网。

3. 通过systemd管理caddy

sudo systemctl start caddy.service
sudo systemctl stop caddy.service
sudo systemctl restart caddy.service
sudo systemctl reload caddy.service
