MDS, PHP and authentication

Recently I blogged about how to easily deploy a LAMP application to MDS.

Using the Terraform module (OCI Resource Manager’s Stack) you also have the possibility to choose the PHP version to install:

But as you should already know, not all versions support the latest default authentication method in MySQL 8.0: caching_sha2_password [1], [2], [3].

Most of the PHP applications are using mysqli and mysqlnd

MySQL Cluster NDB API Hello World!

In this post I will show how to program a C++ client for MySQL NDB Cluster. I have already presented MySQL Cluster, the distributed database using the in-memory storage engine, in several occasions. You may have learnt how to configure and start MySQL Cluster, so I will assume that a cluster is up and running. If you want to develop a simple C++ client, just run the cluster in a single host, which may be your very laptop. In order to compile an NDB API client, you will need.

  1. MySQL NDB Cluster installed. Community distributions are here (I like to work with the self contained TAR).
  2. The cluster up and …

MySQL Shell 101 – System Log

One of the new features introduced in MySQL 8.0.24 was the ability to log all SQL statements that are issued in the MySQL Shell to the system log. This is a useful feature that can greatly assist in tracking who did what on the system.

Usage

The simplest way to utilize the new Shell logging feature is to simply start the MySQL Shell with the syslog option enabled like so:

$> mysqlsh --syslog --sql root@localhost

From this point forward all SQL entered in the MySQL Shell will be logged to the system log. For example, the following SQL is entered into the Shell:

MySQL  localhost:33060+ ssl  SQL > show databases;

+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
+--------------------+

We can now check the system log and verify that the statement above was indeed …

Using MySQL 8 Dual Passwords

MySQL 8 brought many highly anticipated features, with support for user roles, a new shell, a more robust data dictionary, and better SQL support, just to name a few. There are lesser-known new features, however, that aim to reduce overall DBA workload and streamline management processes – and one of these is support for dual passwords, first implemented in MySQL 8.0.14. User accounts are now permitted to have dual passwords, with a designated primary and secondary. This makes it possible to seamlessly perform user credential changes even with a large number of servers, or with multiple applications connecting to different MySQL servers.

Historically, a MySQL credential change had to be timed so that when the password change was made and propagated throughout the database nodes, all applications that use that account for connections had to be updated at the same time. This is problematic for many reasons, but with database and application …
