Configuring the MySQL Shell Prompt

Tweet

With the introduction of MySQL Shell 8.0, the second major version of the new command-line tool for MySQL, a new and rich featured prompt was introduced. Unlike the prompt of the traditional mysql command-line client, it does not just say mysql> by default. Instead it comes in a colour coded spectacle.

The default prompt is great, but for one reason or another it may be that you want to change the prompt. Before getting to that, let’s take a look at the default prompt, so the starting point is clear.

The Default Prompt

An example of the default prompt can be seen in the screen shot below. As you can see, there are several parts to the prompt, each carrying its information.

InnoDB Cluster in a Nutshell Part 3: MySQL Shell

Welcome to the third part of this series. I’m glad you’re still reading, as hopefully this means you find this subject interesting at least. Previously we presented the first two components of MySQL InnoDB Cluster: Group Replication and MySQL Router and now we will discuss the last component, MySQL Shell.

MySQL Shell

This is the last component in the cluster and I love it. Oracle have created this tool to centralize cluster management, providing a friendly, command-line based user interface.

The tool can be defined as an advanced MySQL shell, which is much more powerful than the well known MySQL client. With the capacity to work …

MySQL InnoDB Cluster : MySQL Shell and the AdminAPI

As promised, here is a post more detailed on how to create a MySQL InnoDB Cluster using MySQL Shell and the AdminAPI.

First of all, as a good practice is never enough repeated, whatever the version of MySQL you are using, please use the latest MySQL Shell ! So if you are using 5.7, please use MySQL Shell 8.0.11. See this compatibility matrix or this official one.

dba class

The AdminAPI can be accessed by the MySQL Shell via the dba object. The reference manual for this class is here. The Shell …

MySQL 8.0 InnoDB Cluster – the quick hands-on manual

I’m just back from a trip in Barcelona where I presented MySQL 8.0 InnoDB Cluster (at dataops and Barcelona MySQL Meetup) and the majority of feedback was great, but I also had some comments on the demos I showed. The first one was:

This is a joke of course (maybe it’s true for some), people found it very easy and they liked it.

But then, the second one was that all I showed wasn’t easy to find, some people who already played with the solution didn’t succeeded in creating a cluster so easily… not because they had errors or encountered bugs, but more because they just didn’t know how to do it.

The goal of this …

Top 10 reasons for NoSQL with MySQL

As you know, one of the great new feature in MySQL 8.0 is the Document Store. Now with MySQL you can store your JSON documents in collections and manage them using CRUD operations. NoSQL is now part of MySQL ! Instead of a mix of MongoDB and MySQL, now you can eliminate MongoDB and consolidate with MySQL !

This is a historical meeting of NoSQL and SQL in the same database server!

To use MySQL 8.0 as Document Store, you need to have the X plugin installed (by default since 8.0.11). This plugin enables the X DevAPI that offers a modern programming interface. Clients that communicate with a …

MySQL InnoDB Cluster – Compatibility Matrix

Recently during my several talks and trips to meet the MySQL Community and MySQL InnoDB Cluster, I realized that some important message was missing. I got a lot of questions about which version of Router or Shell people should use. There is some confusion about which version to use, it seems that people thinks they should use MySQL Shell 1.0.x and MySQL Router 2.1.x with MySQL 5.7 and use the 8.0.x version having the same version as MySQL 8.0. This is wrong !

In fact, whatever the version of MySQL InnoDB Cluster you are using, you should ALWAYS use the latest version of Router and Shell. Currently it’s 8.0.11. So yes, even if you use MySQL 5.7.22, you MUST use MySQL Router 8.0.11 and …
