Today we will see how to install WordPress in Oracle Cloud (OCI).

We will use Oracle Cloud’s Free Trier and deploy 2 compute instances:

• the webserver (apache, PHP and WordPress)
• the database server (MySQL 8.0)

We will use one public IP to reach our site and our two servers will communicate using their own private network:

Deploying 2 compute instances

Let’s start by creating 2 compute instances:

We will use the Oracle Linux 7.7 on Micro Instances:

As I am in Belgium, I use the Frankfurt datacenter.

When our instances are deployed, we can find the public IP of one of them. This is the one we will use as webserver (you can free the public IP on the other one, the MySQL one):

At the creation, we entered a ssh key to access …

As you know, Oracle Cloud Infrastructure (aka OCI) becomes more and more popular. You can find OCI data centers almost everywhere and the price is very attractive.

Something very interesting is the possibility to have different availability domains but also different fault-domains in the same availability one !

Oracle provides a lot of modules to deploy your architecture on OCI using Terraform. Those are called oracle-quickstart repos. You can find them on Github.

There is an official Reference Architecture for MySQL InnoDB Cluster in OCI that I encourage you to read before deploying your MySQL HA solution …
