need database configaration before step 6

STEP 6

Configure nginx

  
    sudo nano /etc/nginx/sites-available/yourdomain.com
    #this is for next js
    server {
    listen 80;
    server_name yourdomain.com www.yourdomain.com;
    location / {
        proxy_pass http://localhost:3000; # Next.js runs on port 3000
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        }
    } 
    sudo ln -s /etc/nginx/sites-available/yourdomain.com /etc/nginx/sites-enabled

    #this is backend server setup
    server{
        listen 80;
        server_name api.myfinancialtrading.com;

        location / {
                proxy_pass  http://localhost:3000;
            # Add other proxy settings if needed
               proxy_set_header Host $host;
               proxy_set_header X-Forwarded-Host $host;
               proxy_set_header X-Forwarded-Proto $scheme;
               proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
     }


   ##For Websocket

  sudo nano etc/nginx/conf.d/file.conf


   
    server{
        listen 80;
        server_name api.myfinancialtrading.com;
           client_max_body_size 1000M;

      location / {
             proxy_pass http://localhost:5008;
             
             # WebSocket-specific headers
             proxy_http_version 1.1;                 
             proxy_set_header Upgrade $http_upgrade; 
             proxy_set_header Connection "Upgrade";  
         
             # Additional proxy headers
             proxy_set_header Host $host;                    
             proxy_set_header X-Forwarded-Host $host;      
             proxy_set_header X-Forwarded-Proto $scheme;     
             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
         
             # Optional: Disable caching for WebSocket connections
             proxy_cache_bypass $http_upgrade; # Ensures that WebSocket connections are not cached.
         }

     }
    
    sudo ln -s /etc/nginx/sites-available/api.yourdomain.com /etc/nginx/sites-enabled
    sudo nginx -t
    sudo systemctl reload nginx
  

create folder

  
    sudo mkdir -p /var/www
  

  
    ls -l /var/www
  

STEP 7

     sudo nano /etc/mongod.conf 


   replication:
    replSetName: "rs0"

   sudo systemctl restart mongod
     mongosh
     rs.initiate()

   ## for env 
     DATABASE_URL="mongodb://127.0.0.1:27017/kumba?replicaSet=rs0"
   
    
  

STEP 9
