Intro

In a set of blog posts I will explain to you how different attacks on the network traffic of MySQL look like and what you can do to secure your systems againt these kinds of attacks.

How to gain access

To gain access to MySQL network traffic you can use tcpdump, dumpcap, snoop or whatever the tool to capture network packets on your OS is. This can be on any device which is part of the connnection: the server, the client, routers, switches, etc.

Besides application-to-database traffic this attack can also be done on replication traffic.

Results

This allows you to extract queries and result sets.

The default password hash type mysql_new_password uses a nonce to protect against password sniffing. But when you change a password this will be sent accross the wire by default. Note that MySQL 5.6 and newer has …

In this blog post, we’ll discuss services monitoring using probabilistic fault detection.

Let’s admit it, the task of monitoring services is one of the most difficult. It is time-consuming, error-prone and difficult to automate. The usual monitoring approach has been pretty straightforward in the last few years: setup a service like Nagios, or pay money to get a cloud-based monitoring tool. Then choose the metrics you are interested in and set the thresholds. This is a manual process that works when you have a small number of services and servers, and you know exactly how they behave and what you should monitor. These days, we have hundred of servers with thousands of services sending us millions of metrics. That is the first problem: the manual approach to configuration doesn’t work.

That is not the only problem. We know that no two servers perform the same because no two servers have exactly the …

We saw yesterday that the new MySQL Shell was out and how we could create a MySQL InnoDB Cluster manually using the Shell.

Today, I would like to show you how easy it is to create recipes to automate all the process. I have created a Puppet module that can be used as Proof-of-concept (You might need more features to use it in production, feel free to fork it).

The module can be found on this github repo.

When using Puppet, I really like to put all configuration in hiera.

Environment

We have 3 GNU/Linux servers: mysql1, mysql2 and mysql3.

We won’t install anything related to MySQL manually, everything will be handled by Puppet.

 Earlier this week,  MySQL Shell 1.08 has been released. This is the first Release Candidate of this major piece of MySQL InnoDB Cluster.

Some commands have been changed and some new ones were added.

For example the following useful commands were added:

• dba.checkInstanceConfiguration()
• cluster.checkInstanceState()
• dba.rebootClusterFromCompleteOutage()

So let’s have a look on how to use the new MySQL Shell to create a MySQL InnoDB Cluster.

Action Plan

We have 3 blank Linux servers: mysql1, mysql2 and mysql3 all running rpm based Linux version 7 (Oracle Linux 7, CentOS 7, …).

We will install the required MySQL yum repositories and install the needed packages …
