This blog post discusses how to use MySQL shell securely from Bash.

The Bourne shell is everywhere. It is part of the most basic Linux install. You will find it on the biggest SPARC machines down to a Raspberry Pi. It is nice to know it will always be there. Unlike other, more complex scripting environments such as Perl and Python, it doesn’t require any additional dependencies to be installed.

Anyone that has automated a MySQL task using a Bourne shell such as Bash will be familiar with the following message:

Warning: Using a password on the command line interface can be insecure.

This semi-ominous warning describes a security flaw in passing credentials on a process command line. Any unprivileged user on the system can use a command …

How does an application configure its database connection?  I find this to be a pretty interesting question. As the application moves from a developer’s workstation to a test harness, then to staging, and on to production, the database connection properties can change each time. …

In MySQL 5.7 we introduced JSON functionality into the MySQL Server. This work included the introduction of a JSON data type, virtual columns and a set of approximately 20 SQL functions that allow you to manipulate and search JSON data on the server side.…

The second MySQL tutorial session at Oracle Open World was “MySQL Group Replication in a Nutshell” by MySQL Community Manager Frederic Descamps. This is succinctly described as:

“Multi-master update anywhere replication for MySQL with built-in conflict detection and resolution, automatic distributed recovery, and group membership.”

MySQL Group Replication (GR) is a virtually synchronous replication solution which is an integral component of MySQL InnoDB Cluster announced at the MySQL keynote. You can download a labs version of MySQL InnoDB cluster which includes three components.

Somebody recently asked, what they had to do, if they wanted to move their InnoDB-Logfiles back to the datadir. As a challenge, the servers were part of a Galera Cluster.

My first thought was:

The problem is not the Galera Cluster itself, it is the rsync-SST (wsrep_sst_method = rsync) that could cause trouble and destroy your InnoDB-Logfiles, by simply overwriting or deleting them.

So I tried to confirm my thought and realised, I was wrong. This works anyway, because the node just takes the dataset from the other node. (The backup plan was ready now.)

Preferably, the cluster does an IST, where it only fetches the missing write sets. This way you do not have the danger of losing the …
