When the use of the Nginx internet server, you’ll use server blocks (very similar to digital hosts in Apache) to encapsulate configuration main points and host a couple of area from a unmarried server. We will be able to arrange a website known as instance.com, however you will have to change this with your individual area title. To be told extra about putting in a website title with DigitalOcean, see our introduction to DigitalOcean DNS.

Luck! The instance.com server block is operating!

Save and shut the report if you end up completed.

Make a brand new server block at /and so on/nginx/sites-available/instance.com:

  • sudo nano /and so on/nginx/sites-available/instance.com

Paste within the following configuration block, up to date for our new listing and area title:

/and so on/nginx/sites-available/instance.com

server {

Two server blocks at the moment are enabled and configured to answer requests in keeping with their pay attention and server_name directives:

  • instance.com: Will reply to requests for instance.com and www.instance.com.
  • default: Will reply to any requests on port 80 that don’t fit the opposite two blocks.

To steer clear of a imaginable hash bucket reminiscence drawback that may get up from including further server names, it is important to regulate a unmarried worth within the /and so on/nginx/nginx.conf report. Open the report:

  • sudo nano /and so on/nginx/nginx.conf
