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.
