Step 2: Add a custom domain name (optional)

Let’s assume our domain name is www.example.com

Get a domain name from any domain name registrar.
Set up the DNS records for your domain by using a DNS hosting service (which DigitalOcean provides).
Add the domain to your DigitalOcean account:
- Modify the A flag to assign your domain to the right droplet
- Modify the CName flag to allow the www.example.com to link to the domain name (without www).

How to optimize Nginx configuration

Worker Processes and Worker Connections

Two variables need to be tuned here:

Download & install Google Chrome Google Chrome is a fast, free web browser. Before you download, you can check if Chrome supports your operating system and you have all the other system requirements.

A more simple, secure, and faster web browser than ever, with Google’s smarts built-in. Free install google chrome.

worker_processes: a common practice is to run 1 worker process per core. To figure out what number you’ll need to set worker_processes to, simply take a look at the amount of cores you have on your setup. Use the following bash code:

worker_connections: tells our worker processes how many people can simultaneously be served by Nginx. Default value is 768. Check your core’s limitations by using the following bash command:

On a smaller machine (512MB droplet) this number will probably read 1024, which is a good starting number.

Update your config file as follow

Remember, the amount of clients that can be served can be multiplied by the amount of cores. In this case, we can server 1024 clients/second. This is, however, even further mitigated by the `keepalive_timeout directive.

How to Kill a process running on port 80

If you get following error, when you try to start nginx…

Heroku’s free cloud services begins with the apps - apps which can be deployed to dynos - our lightweight Linux containers that are at the heart of the Heroku platform.When you sign up with Heroku, you automatically get a pool of free dyno hours to use for your apps. Install letsencrypt heroku free. Heroku plugins:install heroku-cli-oauth; heroku authorizations:create -d 'letsencrypt-heroku' Save the token from this. We'll use it later. Installation on Heroku. Deploy automatically to Heroku using this button: Input all the required parameters as asked for by the Heroku setup wizard. This includes the heroku token from above.

Then it means nginx or some other process is already using port 80.
