### Instalação do Proxy Reverso NGINX

Exemplo de configuração do proxy reverso utilizando o nginx.

```shell
map $http_x_forwarded_proto $protoscheme {
    default $scheme;
    https https;
}

# required for WebSockets
map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}

upstream ws-simon-bal {
    server 127.0.0.1:80; # IP Master Node
}

server {

    # ...

    keepalive_timeout   60;
    server_tokens off;

    # Strict Transport Security
    add_header Strict-Transport-Security max-age=2592000;

    # proxy buffers
    proxy_buffers 16 64k;
    proxy_buffer_size 128k;

    location ~* ^/(ws)/ {
        rewrite  ^/(ws/.*)$ /$1 break;
        proxy_pass         http://ws-simon-bal;
        # proxy_redirect    off;
        proxy_redirect     http://ws-simon-bal/ $scheme://127.0.0.1/;

### Instalação do Proxy Reverso Apache2

Exemplo de configuração do proxy reverso para apache com os modulos obrigatórios: (*proxy, rewrite, proxy\_http, proxy\_wstunnel*).

```shell
a2enmod proxy rewrite proxy_http proxy_wstunnel
```

```shell

# Exemplo para porta 80/443
# Redirecionar tráfego da porta 80 -> 443

<VirtualHost *:80>
  ServerName simon.seudominio.com
  # ... Outras configurações

  Redirect permanent / https://simon.seudominio.com
  
</VirtualHost>

<VirtualHost *:443>
  
  ServerName simon.seudominio.com

  # ... Outras configurações

  ProxyRequests Off
  ProxyPreserveHost On

  # Suporte à Websockets
  RewriteEngine On  
  RewriteCond %{REQUEST_URI}   ^/                [NC]
  RewriteRule /(.*)            http://simon.seudominio/$1 [P,L]
  RewriteCond %{HTTP:Upgrade}  =websocket        [NC]
  RewriteCond %{REQUEST_URI}   ^/ws/             [NC]
  RewriteRule /(.*)            ws://simon.seudominio/$1   [P,L]

  # 
  ProxyPass        / http://simon.seudominio/ timeout=600
  ProxyPassReverse / http://simon.seudominio/ timeout=600

</VirtualHost>
```
