VPS

Buy a VPS with external IP address. I used a ubuntu server.

In Godaddy console panel, set A address for the VPS IP address. Such as host.name.

the generate certification will be put at /etc/letsencrypt/live/

apt install nginx

Trojan-Go Server

Download trojan code

git clone https://github.com/p4gefau1t/trojan-go.git

Build binary

go build -o trojan --tags "full" # go 1.17
mv trojan ~/.local/bin # add ~/.local/bin to your PATH
