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 …

This topic is about general usage for MySQL Shell and X-Plugin.
The most important thing, i think we should keep in mind that, the X-Plugin will listen not MySQL’s port, but it’s own 33060 port as shown from log:

2016-07-15T07:21:09.454761Z 200 [Note] Plugin mysqlx reported: 'X plugin tcp connection enable at port 33060.'

2016-07-15T07:21:09.501752Z 0 [Note] Plugin mysqlx reported: 'Server starts handling incoming connections'

That’s …

Interesting developments in the MySQL world – it can now be used as a document store and you can query the database using JavaScript instead of SQL (via the MySQL Shell). There is also a new X Plugin (see: mysql-5.7.12/rapid/) (which now makes use of protocol buffers (see: mysql-5.7.12/extra/protobuf/)). I will agree, this is more than just a maintenance release.

Do get started playing with MySQL Shell. If you’re using the yum repository, remember to ensure you have …

Recently Todd Farmer shared an interesting story about the mysql command line prompt in MySQL 5.7: how it was changed to provide more context and why the change was finally reverted. This made me think that after using the command line client for MongoDB for awhile, I would love seeing a much more modern mysql shell prompt. Here are a few examples of what a modern command line client can do.

Add dynamic information to the prompt

If you use replication with MongoDB, you have probably noticed a nice feature of the prompt: it is replication aware. What I mean is that for a standalone instance, the prompt is simply:

>

When you configure this instance to be the primary of a replica set named RS, the prompt automatically becomes:

RS:PRIMARY>

and for secondaries, you will see:
