Steps to MySQL Management

Here are the steps that are required for MySQL management as a DBA:

1. Installation

The “yum” tool is your friend.  If you’re using Debian, you’ll use apt-get but it’s very similar. You can do a “yum list” to see what packages are available. We prefer to use the Percona distribution of MySQL.

It’s fully compatible with stock MySQL distribution, but usually a bit ahead in terms of tweaks and fixes. Also, if you’re not sure, go with MySQL 5.5 for new installations. …

There are a lot of considerations for deploying MySQL in the Cloud. Some concepts and details won’t be obvious to DBAs used to deploying on traditional servers.

For this, we have provided eight best practices in this guide that will certainly set you off on the right foot. Let’s explore them below.

8 Practices You Should Follow While Deploying MySQL on Amazon

Here are eight best practices that you must follow while deploying MySQL on Amazon:

1. Replication

Master-Slave replication is easy to setup and provides a hot online copy of your data.  One or more slaves can also be used for scaling your database tier horizontally.

Master-Master active/passive replication can also be used to bring …

There is no need to mention that speed is one of the most sought-after attributes in any database system. Optimizing MySQL for high speed is essential to ensure responsive applications and efficient data processing.

There are basically two best ways to speed up UNION in MySQL – using UNION ALL and using push-down conditions.

In this article, we’ll explore techniques to achieve optimal performance and speed in MySQL.

Ways to Optimize MySQL for High Speed

Here’s a rundown of how to do those optimizations.

1. UNION ALL is much faster than UNION

How does a UNION work? Imagine you have two tables for shirts. The short_sleeve table looks like this:

And long_sleeve another that looks like this:

In today’s data-driven world, ensuring the safety of your valuable data is crucial.

To safeguard this data using MySQL, implementing a robust backup strategy is essential.

For this, we have mentioned ten important things to consider while dealing with MySQL backups. Let’s learn them in detail below.

10 Things You Must Do While Backing Up MySQL

Here are ten important considerations to keep in mind when dealing with MySQL backups.

1. Use Hot Backups

Hot backups are an excellent way to back up MySQL. They can run without blocking your application, and save tons of restore time. Percona’s xtrabackup tool is a great way to do this.  We wrote a how-to on using xtrabackup for hotbackups.

1. Use Logical Backups

Just because we …

This blog was originally published in February 2017 and was updated in September 2023.

In this blog post, I provide an in-depth introduction to MySQL Replication, answering what it is, how it works, its benefits and challenges, as well as reviewing some of the MySQL replication concepts that are part of the MySQL environment (and Percona Server for MySQL specifically). I will finish by also clarifying some of the common misconceptions people have about replication and how Percona can help.

Since I’ve been working on the Solution Engineering team, I’ve noticed that – although information is plentiful – replication is often misunderstood or incompletely understood.

You may already know that when the mysqldump client utility performs logical backups, it produces a set of SQL statements that you can execute to reproduce the original database object definitions and table data.

Although it dumps one or more MySQL databases for backup or transfer to another SQL server, there are 5 things that you may overlook with MySQL dumps.

Here I’ve discussed 5 things you shouldn’t overlook with MySQL dumps. Let’s explore them below.

5 Things You Need to Concentrate About MySQL Dumps

Here are the five things you may overlook with MySQL dumps:

1. Point In Time Recovery

If you’ve never done point in time recovery, it’s time to take a second look. With a standard mysqldump you restore your database to the time when the backup happened. Only do them once a day, then you can lose as much as 24 hours of data.

Enter point-in-time recovery, and you …

Autoscaling your webserver tier is typically straightforward. Image your Apache server with source code or without, then sync down files from S3 upon spinup. Roll that image into the autoscale configuration and you’re all set.

With the database tier though, things can be a bit tricky. The typical configuration we see is to have a single master database where your application writes. But scaling out or horizontally on Amazon EC2 should be as easy as adding more slaves, right? Why not automate that process?

Below we’ve set out to answer some of the questions you’re likely to face when setting up slaves against your master. We’ve included instructions on building an AMI that automatically spins up as a slave. Fancy!

1. How Can I Autoscale My Database Tier?

Step 1: Build an auto-starting MySQL slave against your master.

Step 2: Configure those to …
