Lets encrypt Nginx

Introduction

Let’s Encrypt is a Certificate Authority (CA) that provides an easy way to obtain and install free TLS/SSL certificates, enabling encrypted HTTPS on web servers. It simplifies the process by providing a software client, Certbot, that attempts to automate most (if not all) of the required steps. Currently, the entire process of obtaining and installing a certificate is fully automated on both Apache and Nginx.

In this tutorial, you will use Certbot to obtain a free SSL certificate for Nginx on Debian 9 and set up your certificate to renew automatically.

FIXING ESXI 6.5 ON HPE G7 SERVERS3 MIN READ

So there I was, moving VMs off of my main host (DL380 G7, 2x x5690’s, 192GB RDIMM), getting ready to replace the 8x 300GB RAID10 array I’ve been using for a while now with some 1TB disks and SSDs, awesome, right?

So the host was powered down, ready for an upgrade, and being the logical guy I am I decided to do some software upgrades.

I used the latest SPP and ran that through, for some reason I was using a BIOS from 2010? Once that was done I had updated firmware, so I moved onto ESXi. I’ve been running 6.0.0U2 for the longest time and thought this would be the ideal time to upgrade.

I got the HPE official ISO, ran through the upgrade, waited for it to boot annnddd….
