When I was preparing this post<\/a> I bought a domain just for testing purposes called nikola-dev.com<\/a>\u00a0and I wanted to have Node.js apps running on this VPS (behind a NGINX running as proxy) but that they would be accessible from different domains (for example mean.nikola-dev.com<\/a>). Below are the steps I needed to take in order to make this happen:<\/p>\n

    \n
  1. Clearly, have a droplet on DigitalOcean<\/a><\/li>\n
  2. Buy a domain (where ever you buy it, make sure you use Honey<\/a>, to get the best price)<\/li>\n
  3. Edit the Nameserver information in the admin dashboard of your domain provider (where you bought the domain) to the following three records:
    \nns1.digitalocean.com,\u00a0ns2.digitalocean.com,\u00a0ns3.digitalocean.com<\/li>\n
  4. Add the domain on DigitalOcean DNS settings page:
    \n    \"digitalOcean_dns\"<\/a><\/li>\n
  5. Delete \/etc\/nginx\/sites-enabled\/default<\/strong><\/li>\n
  6. Create\u00a0\/etc\/nginx\/sites-available\/nikola-dev.com<\/strong>\u00a0file with the following content (this will be a simple single HTML file which will list the available test apps on this server):\n
    server {\r\n    listen 80;\r\n    server_name nikola-dev.com;\r\n    root \/var\/www\/nikola-dev.com\/public_html;\r\n}<\/pre>\n<\/li>\n
  7. Create\u00a0\/etc\/nginx\/sites-available\/mean.nikola-dev.com<\/strong>\u00a0file with the following content (this will serve the actual Node.js app that we’re building in this tutorial):\n
    server {\r\n    listen 80;\r\n\r\n    server_name mean.nikola-dev.com;\r\n\r\n    location \/ {\r\n        proxy_pass http:\/\/127.0.0.1:3000;\r\n        proxy_http_version 1.1;\r\n        proxy_set_header Upgrade $http_upgrade;\r\n        proxy_set_header Connection 'upgrade';\r\n        proxy_set_header Host $host;\r\n        proxy_cache_bypass $http_upgrade;\r\n    }\r\n}<\/pre>\n<\/li>\n
  8. Restart NGINX:\n
    sudo service nginx restart<\/pre>\n<\/li>\n<\/ol>\n
    Clearly, if you would need to add more subdomains, just repeat the steps from step 6\u00a0<\/strong>onward. Of course, you would need to put your other Node.js apps on different ports<\/strong>, since only one app can work on one port.<\/p>\n","protected":false},"excerpt":{"rendered":"
