Setup Digital Ocean Droplet

Digital Ocean is a cost effective cloud server solution that you can use to do quick rapid testing on different server configurations. Head over to Digital Ocean, and create a new droplet with the following configurations:

Distribution: Ubuntu ****19.10 x64

Plan: The lowest plan at $5 per month works just fine for testing purposes

Region: Any

Create SKALE Chain

You will need to use a terminal to SSH into your new Digital Ocean server. Open your terminal and run the following commands:

1. Log into your Digital Ocean server

ssh root@[DIGITAL_OCEAN_IP] #example ssh root@123.123.123

2. Install updates

sudo apt-get update

3. Install Docker

sudo apt install docker.io

4. Clone the SKALE Chain SDK repo code

git clone --recurse-submodules https://github.com/skalenetwork/skale-dev-env.git

5. Setup NGNIX

sudo apt update;
sudo apt install nginx;
sudo ufw app list;
sudo ufw allow 'Nginx HTTP';
sudo ufw allow 'Nginx HTTPS';
sudo ufw allow 'OpenSSH';
sudo ufw enable;
sudo ufw status;
****sudo systemctl start nginx; 

nano /etc/nginx/sites-available/default

Update the server file to be:

server {
        listen 80;
        listen [::]:80;

        root /var/www/html;

        # Add index.php to the list if you are using PHP
        index index.html index.htm index.nginx-debian.html;

        server_name myservername.com;

				location /skaled-blockchain-explorer {     
          try_files $uri $uri/ =404;
        }

				location /skaled-stats-viewer {     
          try_files $uri $uri/ =404;
        }

        location / {
            proxy_set_header X-Real-IP
            $remote_addr;
            proxy_set_header
            X-Forwarded-For
            $proxy_add_x_forwarded_for;
            proxy_set_header Host
            $http_host;
            proxy_set_header
            X-NginX-Proxy true; proxy_pass
            http://123.123.123.123:1234;
            proxy_redirect off;
            proxy_http_version 1.1;
            proxy_set_header Upgrade
            $http_upgrade;
            proxy_set_header Connection
            "upgrade";
            proxy_redirect off;
            proxy_set_header
            X-Forwarded-Proto $scheme;
        }
}

systemctl restart nginx
