On a previous blog post, we saw how to create an account on the Oracle OCI using the Oracle Cloud Free Tier offer and then how to instal MySQL Server on the Compute instance.
Some weeks later, the new MySQL Database Service (MDS) was out and I can show you now how to install and configure it.

We are talking about the MySQL 8.0 Enterprise Edition on the on Oracle Generation 2 Cloud Infrastructure. For the moment it’s only available on some of the data regions (Frankfurt and London for the EMEA zone), but normally others will be …

OCI CLI is a powerful tool that does it all for OCI administration: from creating a compute instance to configuring a Virtual Cloud Network (VCN), from setting up Identity Management Service (IAM) to managing all the different storage flavours. Consult the OCI CLI command reference.

MySQL Database Service (MDS) is not an exception, everything related to the new MySQL Server service running over OCI can be easily managed with a set of commands using OCI CLI, check it here. Starting new DB Systems, creating and managing backups, dealing with …

It’s now more than two months since MDS, the managed MySQL Server solution by Oracle MySQL team, hosted on Oracle Cloud Infrastructure (OCI), became available in several regions on the 1st of September. You can find online several resources online, such as:

• MDS documentation
• Oracle MySQL blog
• MySQL Database Service Release Notes

If you haven’t tried it for free, time to do so with the …

This post was first published on Oracle MySQL Blog.

If you are running MySQL on premise, it’s maybe the right time to think about migrating your lovely MySQL database somewhere where the MySQL Team prepared a comfortable place for it to stay running and safe.

This awesome place is MySQL Database Service in OCI. For more information about what MDS is and what it provides, please check this blog from my colleague Airton Lastori.

One important word that should come to your mind when we talk about MDS is SECURITY !

Therefore, MDS endpoint can only be a private IP in OCI. This means you won’t be able to expose your MySQL …

During the MDS webinar on how to deploy WordPress on OCI using MDS (slides & video), I briefly explained how to deploy the full architecture on OCI using Resource Manager and Stacks.

The Stack for that architecture is now available on my github: https://github.com/lefred/oci-wordpress-mds/releases/tag/0.0.1

To deploy it, it’s very easy. In OCI’s Dashboard, go on “Resource Manager” and then choose “Stacks“:

Create a new stack and just drop the …

Today we will see how to use MySQL Database Service aka MDS with WordPress.

To achieve this easy task, we will use the architecture we already deployed in this article.

We have then two Compute Instances on OCI, 1 running WordPress (Apache and PHP) and one running MySQL 8.0.

The Plan

This is how we will proceed to migrate to MDS with minimal maintenance time, we will:

1. create a MDS instance
2. verify if the database is ready to act as replication source
3. dump the MySQL instance running on OCI for being migrated to MDS.
4. load the dump in MDS
5. create a user dedicated to the replication
6. create a replication channel on MDS (from OCI to MDS)
7. modify WordPress config to point to MDS

Create a MDS …

In a recent article, I explained how to test MySQL Database Service (aka MDS) on OCI without having to setup a VPN.

A VPN is the recommended way and of course using some man-in-the-middle exposing the MySQL Classic and X Protocol port is something you should absolutely avoid !

So, in this article we will see another way to test or use MDS without VPN but using a more secure option.

SSH

The solution uses a SSH tunnel between your machine (laptop, etc..) and OCI.

How does it work ?

We have a MDS instance (10.0.1.3), and a compute instance (10.0.0.2). The compute instance is in the public subnet and has a public IP assigned to it.

Then we open a SSH tunnel to the compute instance’s public IP that forward all traffic to a certain port on localhost (we will use 3406) …

Please note that this is not recommended for any production purpose, don’t expose MySQL traffic to the Internet !

MySQL Database Service is now available, take a look at this nice introduction video:

It is usually a very bad idea to expose a database on a public IP (MySQL or any other database ). MDS doesn’t allow you to implement such bad security practice.

The best way to use your MySQL instance is to use a VPN as I explained in this article.

However, this can be restrictive for a simple test. In this post I will illustrate how you can setup a MDS instance and test it without having to setup any kind of VPN. Of course I recommend you to use such practice only for testing …

You may have noticed, I started to blog also on the official Oracle MySQL Blog.

When I will do so, I will also publish my articles on lefred.be after a short delay.

I really invite you to follow the official Oracle MySQL Blog where you will find information related to MySQL Community but also about our webinars.

Currently, we put the highlight on our great new MySQL Database Service on OCI. My first post, is precisely dedicated to it.

This year’s last log buffer edition looks at the marvelous and splendid blog posts of Oracle, SQL Server and the MySQL databases which promise to bring more and more next year. This Log Buffer #301 promises to be the anchor for yet another action packed blogging carnival next year.
