Here is how to set up a MySQL-compatible database in Amazon Web Services,
in case it is useful to anyone:

- Go to the AWS console and log on. Yes, you need an account.

- Select an appropriate region.

- Select "RDS" (Relational Database Service) from Services.

- Select "Create database".

- You have a choice of MySQL, MariaDB, and Amazon Aurora MySQL-compatible
edition. I'm using Aurora. Subsequent settings may depend on the variant

- I suggest turning on "Show versions that support Serverless v2" and
choosing the one available version, currently "Aurora MySQL 3.02.0
(compatible with MySQL 8.0.23)". (Having said that, I don't think this
qualifies for the free tier.)

Skipping many settings where the defaults are OK and/or the choice
is obvious...

- In "Instance configuration", choose "Serverless" and set min and max
memory sizes (I'm trying 0.5 and 2).

- In "Connectivity", you can either choose "Public access - yes" in
which case you'll be able to connect from a client outside AWS, or
"Public access - no" and a VPC/subnet, in which case you'll be able
to connect only from within AWS, e.g. from an EC2 instance.

- Note that the "VPC security group" is essentially the firewall
rules for the database. Choosing "create new" will open the default
port 3306. Take care with this, it may have granted access only to
the IP address of my web browser when I tried it just now.

- I don't suggest letting it generate the password automatically, I
don't think it told me what it was :-( You can change it later.

- Click "Create database".

- You should now see a simple tree of instances with a parent
"Regional Cluster" with a single child "Writer Instance". Wait until
both show Status Available.

- Copy the "Endpoint name" for the "Writer instance".

- On your client, try to connect using the endpoint name as the

$ mysql -h -P 3306 -u admin
Enter password:

(Beware of -p vs. -P on the command line there...)

Now to see if I can make this library communicate with it!

Regards, Phil.
