Create Let's Encrypt SSL with Ubuntu

This video will show how you can use Certbot to create Let's Encrypt SSL certificates. This is the process we use to create certificates for our video tutorials.
Some organizations will also use Let's Encrypt SSL certificates for production usage.

You might have another web server running

What do you use to create the A records?

[@evermightsystems]

Thanks for your message. I use the DNS editors that come with any place where you've bought your domain from. Sometimes I might just add an entry to /etc/hosts file or the C:\Windows\System32\drivers\etc\hosts file of every machine as an alternative. I think you'll be able to find lots of blog articles online that explain how DNS editors work or how host files work. Good luck!

[@kientrung-io4jt]

can you explain how to setup that domain name. i mean that when start you ping to the domain name but not tell me how you setup to ping

[@evermightsystems]

Sure. Basically you need to go to where you originally bought your top level domain (eg. GoDaddy, google, hostgator etc...). Then you click on the DNS manager. Then you click add new "A Record". Then type the subdomain and the IP address of the server you want to point the sub domain too.

@@evermightsystems currently i not use any domain name, i just want to slove big data problem, can i use /etc/hosts to map ip or any easier solution

[@evermightsystems]

@@kientrung-io4jt Let's Encrypt needs to be able to reach your server via domain name to be able to generate the cert. That's the whole goal/purpose of publicly signed certificates, their job is to act as a 3rd party external organization to verify the domain you request SSL for does indeed belong to the server.
If you want to use /etc/hosts, then you'll need to create your own self signed certificates. I do not have a video yet on self signed certificates.

[@evermightsystems]

I do have videos on creating self-signed certificates for just the elasticsearch platform for any of my tutorials on setting up ELK. But if you're not doing anything with ELK, then those videos would not be relevant to you.
