Open Port 80 Oracle Cloud Compute Instance (CentOS)

FYI This was harder than it needed to be:

1. Looking at your instance info, find VNIC section, click "Public Subnet".
2. Click on your security list.
3. Add a new entry with the following options:

• "Stateless" = No, "Source" = 0.0.0.0/0, "IP Protocol" = TCP, "Source Port Range" = All, "Destination Port Range" = 80

4. SSH to your instance.
5. While SSH'ed in your instance, run command firewall-cmd --permanent --add-service=http.
6. While SSH'ed in your instance, run command firewall-cmd --reload.
7. Now start Apache, NGINX, or whatever server you need to on port 80. You can now access from the internet.

Mounting VirtualBox shared folders on Ubuntu Server 18.04 LTS (Bionic Beaver)

This guide will walk you through the steps on how to setup a VirtualBox shared folder inside your Ubuntu Server guest.

Prerequisites

This guide assumes that you are using the following setup:

• Oracle VM VirtualBox version 6.0.10 with Extension Pack installed
• Microsoft Windows 7 SP1 as the host OS
• A fresh install of Ubuntu Server 18.04.2 LTS as the guest OS

You could still make this guide work with other setups (possibly with some modifications to the commands and whatnot).
