How to get started learning Infra with a Homelab

Sun, 29 Sep 2024 22:12:09 +0000

Here is my recommendation for quickly learning at least the basics of infrastructure:

Hardware:

If you can start with a cluster of at least 3 computers.
- If not a single computer for a hypervisor will work
- If not then VirtualBox or VMWorkstation will get you started with the absolute basics until you can get a hypervisor
If you have a couple old computers or laptops (at least 8gb ram each) then start with those.

AWS Lightsail Wordpress Let's Encrypt Renewal

Problem:

Let’s Encrypt certificate expired

Time: 1 minute

Solution:

All you have to do is run a single command:

sudo /opt/bitnami/bncert-tool

Enter the domain names of your website and press enter.

I choose to enable HTTP -> HTTPS redirection, because I want users to use the https version of the site.

I also went with www to non-www redirection because I already have a dns rule that points all www requests to the non-www address, so this should make no real difference but seems simpler to me.

How the problem was resolved:

Was the problem resolved?

No, the initial problem was fixed, the server booted and all checks were good, but it failed again after a month.

Update 2024:

The issue seems to persist, occasionally powering off abruptly. It happens about once every few months.
