Speed up & Secure with CloudFlare

Overall

To make your server safer, you can use Nginx Reserved Proxy and WebSocket supported CDN to hide your original IP and speed up, we take a VPS and a CloudFlare as example to show how to do.

---

Situation

1. Your ISP didn't provide you with a public IP address.
2. You have a VPS, with Nginx (Port 80), local web expose tool (Port 8080, for example Frp-Server) is installed, and your Raspberry has also installed Frp-Client.
3. You have your own domain
4. You have a CloudFlare Account, and your domain is hosted in it.

---

How to do

1. Switch on the WebSocket in CloudFlare Dashbroad (Your Domain ––> Network --> WebSockets --> Switch On).
2. Add your record, forwarding to your VPS and light the "cloud", we set "s.example.org" here.
3. Login to your VPS, edit /etc/hosts, add the following line:

127.0.0.1 s.example.org

4. Edit Nginx configure file by the following, it'll work on https://s.example.org/webview/ and WebSocket will work in wss://s.example.org/ws/, the root path can put your profile https://s.example.org/.

server {
    listen 80;
    server_name s.example.org;
        location /webview/ {
        proxy_pass http://s.example.org:8080/;
        proxy_next_upstream error timeout invalid_header http_500 http_503 http_404;
        }
        location /ws/ {
        proxy_redirect off;
        proxy_pass http://s.example.org:8080/ws/;
        proxy_next_upstream error timeout invalid_header http_500 http_503 http_404;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $http_host;
        }
    index index.php index.html index.htm default.php default.htm default.html;
    root /www/htdocs;
    error_page 404 /404.html;
    error_page 502 /502.html;
    access_log  /www/logs/access.log;
    error_log  /www/logs/error.log;
}

5. Set the local listen port to 8073 in Frp-Client configure file frpc.ini, and run Frp-Client in its folder ./frpc -c ./frpc.ini (Frp-Server should be running).

[common]
server_addr = 1.2.3.4
server_port = 3000
token = 123456
login_fail_exit = false
[web]
type = http
local_ip = 127.0.0.1
local_port = 8073
use_encryption = false
use_compression = false
custom_domains = s.example.org

6. In htdocs/openwebrx.js, replace any ws:// with wss://, in config_webrx.py, set:

server_hostname="s.example.org/webview/"

in openwebrx.py, replace line 673 with:

("%[WS_URL]","wss://s.example.org/ws/"),

7. Ok, now type python openwebrx.py in terminal, and open https://s.example.org/webview in your browser, it runs!
