At my FOSDEM talk earlier this year, I gave a trick for fixing a crashed GTID replica.  I never blogged about this, so now is a good time.  What is pushing me to write on this today is my talk at MinervaDB Athena 2020 this Friday.  At this conference, I will present more details about MySQL replication crash safety.  So you know what to do if you want to learn more about

If you started looking at running your MySQL database on the cloud and thought that taking your data to Oracle Cloud Infrastructure (OCI) is an option (and wondering about integrating to the new MySQL Acnalytics service), well that is probably the natural choice, because MySQL can integrate easily with OCI services like cloud backups in OCI Object Storage service and OCI keyring for transparent data encryption. I will share a few options with advantages of every solution, so to put the idea into practice.

• MySQL Database Service (MDS)
• MySQL on the OCI Marketplace
• MySQL on OCI do-it-yourself

MySQL Database Service (MDS)

The brand new MySQL Database Service is the easiest way to run your Server in OCI, as it offers several …

Getting MySQL working with self-signed SSL certificates is pretty simple. Having it working with a certificate signed by a trusted authority is also very simple, we just need to set the correct path and privileges to the file. The problem comes when we need to make MySQL validate the certificate signature against the authority public key.

I’ve searched on the internet but wasn’t able to find much information about it. There are a good number of posts on how to set up your own certificate authority and self-sign your certificates, but not much about how to use one signed by a public trusted authority.

I used a certificate signed by a Let’s Encrypt on my tests but the concepts and steps shared here should work for any public trusted authority. I also generated one certificate to be used by MySQL server and another one to be used by the client. It is possible to use the …

The ALTER TABLE statement is one of the most frequently used statements in the MySQL world - the statement allows you to add, delete or modify columns in a table. In this blog post we will try to look deeper into what it is, what it does and when should it be used.

What is ALTER TABLE and What Does it Do?

As already mentioned above, the ALTER TABLE statement enables DBAs and developers to add, delete or modify columns in a table. Simply put ALTER TABLE changes the structure of a table - it enables you to add, delete columns, add or remove indexes, rename columns or change their type.

When and How Do I Use ALTER TABLE?

In order to use ALTER TABLE you generally need the ALTER, CREATE and INSERT privileges. For renaming a table, required privileges are ALTER and DROP for the old table, then CREATE, ALTER and INSERT privileges …

Recently (earlier today), I blogged about how to use PHPMyAdmin with a MDS instance. I also showed at the end of the video that it’s possible to open MySQL Router on the compute instance to connect from anywhere. However this has security risks of course. Therefor, it’s not recommended.

If you want to connect from on-premise to your MDS instance you should use a VPN or a SSH tunnel. Take a look at these previous post:

• https://lefred.be/content/migrate-from-on-premise-mysql-to-mysql-database-service/
• …

I recently received several messages from developers not being comfortable with command line when they need to create schemas, tables, … They were asking me for an easy alternative when testing MDS.

There is a very popular tool in the developer community to manage their databases in MySQL: PHPMyAdmin.

So if you are trying MDS (MySQL Database Service in Oracle Cloud Infrastructure), it’s possible to deploy such instance with a compute instance hosting PHPMyAdmin very easily using OCI’s Resource Manager and a stack (zip file) that you can find here: https://github.com/lefred/oci-phpmyadmin-mds/releases/tag/1.1.0

If you want to try MDS in OCI, you can get free credits using this url: …
