1. 下载caddy存储库：

git clone "https://github.com/caddyserver/caddy.git"

2. 下载xcaddy：

wget https://github.com/caddyserver/xcaddy/releases/download/v0.1.5/xcaddy_0.1.5_linux_amd64.tar.gz
tar -zxvf xcaddy_0.1.5_linux_amd64.tar.gz

3. 编译caddy：

./xcaddy build

添加插件进行编译（这里举例添加caddy的cf与ntlm-transport插件）：

xcaddy build \
    --with github.com/caddy-dns/cloudflare
    --with github.com/caddyserver/ntlm-transport@v0.1.1

完成！
